Description

[Detailed description of the invention]

The present invention relates to milled knitted fabrics. Specifically, the present invention relates to a novel milled-like knitted fabric made of polyester fiber, acrylonitrile fiber, and animal hair, and a method for producing the same. In general, animal blankets that are mainly made of wool can be divided into two types: clear-cut and milled. The characteristic of clear-cut finished products is that the twill of the woven structure is clearly visible in plain textiles, but the twill of the woven structure is not visible in milled finished products due to raised or wrinkled or both. be. In particular, an important feature of flannel, which is a typical milled fabric, is that it is sufficiently shrunk in the warp and weft directions by fullening, and the napping and shearing processes are repeated to neatly entangle the fuzz. Fulling is a phenomenon in which textiles, etc., shrink due to the movement of the fibers that make up the fabric in their axial direction due to repeated external mechanical action, and the shrinking property of animal hair This is because the scale (scale-like structure on the surface of animal hair) causes a directional friction effect. Hydrophobic synthetic fibers that are free of scale and have a smooth surface have no shrinkage properties at all, so non-shrink synthetic fiber/animal hair blends are suitable for clear cut finishing, but they do not have shrinkage properties. When trying to obtain a milled finished product that requires a process, the non-shrinking synthetic fibers block the shrinking of animal hair, so the shrinking effect is generally insufficient and there are problems with texture. Is it what you were doing?
Furthermore, it took several times as long to achieve the same shrinkage properties as 100% animal hair. The present inventors previously proposed a method for improving the above problems in Japanese Patent Application Laid-Open No. 128040/1983, but some problems such as spinnability and drawability of polyester fibers with ultra-high shrinkage ability. Problems remained and stable production was difficult, resulting in the drawback of variations in shrinkage or fabric quality. In view of these points, the inventors of the present invention have arrived at the present invention as a result of intensive studies aimed at making it possible to make flannel fabric a synthetic fiber/animal hair blend that is stable and has consistent fabric quality. The purpose of the present invention is to make the above-mentioned shrinkage property extremely good despite using a synthetic fiber/animal hair blend yarn, and also to improve the shrinkability of natural animal hair by using synthetic fibers. Excellent pleat workability that could never be achieved with milled knitted fabrics made of 100% wool.
The object of the present invention is to provide a novel milled knitted fabric that can satisfactorily impart the characteristics of synthetic fibers such as high strength and durability, and a method for producing the same. This purpose is to provide a milled knitted fabric composed of yarn-dyed blended spun yarn in which short fibers A of polyester synthetic fibers, short fibers B of acrylonitrile synthetic fibers, and animal hair are mixed. short fiber B has a potential shrinkage rate of 5 to 20% when treated with hot water (100℃) and a shrinkage stress capacity of 30 to 300mg/d, and short fiber B has a shrinkage rate of 5 to 20% when treated with hot water (100℃). High contractility with a shrinkage rate of 10-30% and 30-300mg/d during processing
The milled-like fabric is characterized in that the short fiber A and the short fiber B have the latent shrinkage stress ability and the shrinkage stress ability of the short fiber B in the state of the knitted fabric. knitted fabric, and third
Polyester tow contains 1.5 to 20 mol% of copolymerized components, and when treated with hot water (100°C), the shrinkage rate is 10 to 30%, and the shrinkage stress is 30 to 30%.
A copolymerized acrylonitrile tow with a shrinkage capacity of 300 mg/d is tow dyed and cut into short fibers, and then these two short fibers and animal hair are blended to form a spun yarn, and then knitted. This is achieved by a method for manufacturing a milled-like knitted fabric, which is characterized in that it is made into a woven fabric and then subjected to a crimp process. Hereinafter, the milled knitted fabric of the present invention and the method for producing the same will be explained in more detail. The spun yarn used in the present invention is a yarn-dyed blend of polyester synthetic fiber short fiber A, acrylonitrile synthetic fiber short fiber B, and animal hair.
Bicyuna, camel, alpaca, etc. can be used. Polyester synthetic fiber short fiber A has a medium shrinkage capacity of 5 to 20% and developed stress of 30 to 300 mg/
Short fibers B, which are acrylonitrile-based synthetic fibers, potentially have the shrinkage stress capacity of d.
°C) treatment, it potentially has a high contractile ability with a shrinkage rate of 10 to 30% and a contractile stress ability with an expressed stress of 30 to 300 mg/d. Conventionally, blended yarns are blends made by combining natural fibers or synthetic fibers,
Blends of synthetic fibers and natural fibers are common, and in recent years, the latter blending method has become universal, but the basic concept of blending up until now has been from the viewpoint of quality. The aim is to match as much as possible the properties of the fibers to be blended, such as fiber length distribution, single fiber denier, strength and elongation characteristics, etc., and such consideration has usually been taken. Therefore, the combination of blended yarns used in the present invention as described above is very different from the concept used in designing conventional blended yarns. This combination is aimed at achieving a good fulling effect, and to explain this effect in more detail, the fulling caused by felting is originally a behavior unique to animal hair such as wool. The fabric as a whole exhibits area shrinkage as if it had undergone shrinkage. The present inventors have discovered that when the fibers are treated with hot water (100°C) as short synthetic fibers, the shrinkage rate is 10% or more.
High contractility of less than 30% and contraction stress of 30mg/
We found that by using a material that potentially has a high shrinkage stress capacity of d or more and 300 mg/d or less, even fabrics made of synthetic fiber/animal hair blended yarn can easily exhibit good shrinkage properties. However, it is more desirable to mix two or more types of synthetic fibers with different shrinkage capacities, i.e., a mixture of three or more types of fibers including animal hair as a blended yarn, to obtain high shrinkage capacity fibers/medium shrinkage capacity fibers/ It is more effective to have a three-layer structure consisting of low shrinkage fibers, and the short fibers A (medium shrinkage fibers) of synthetic fibers have a shrinkage rate of 5 to 20% when treated with hot water (100℃). Short fibers B (high shrinkage capacity fibers) of synthetic fibers, which have medium shrinkage capacity and potential stress capacity of 30 to 300 mg/d or less, shrink when treated with hot water (100°C). High contractility with a rate of 10-30% and developed stress of 30-300
It is more preferable to use synthetic fibers that potentially have a shrinkage stress capacity of mg/d, and that the synthetic short fibers A are polyester fibers and the synthetic short fibers B are acrylonitrile fibers. We have discovered that even better shrinkage properties can be exhibited. If the shrinkage rate of the short fibers A is less than 5%, the probability of mixing with animal hair to be placed on the surface of the yarn or fabric increases, impeding the shrinkage of the animal hair, and if it is more than 20%, It is not preferable because it is mixed with the short fiber B, which is a high shrinkage component, and forms a core with a hard texture in the yarn or fabric. In addition, the shrinkage rate of short fiber B is
If it is less than 10%, the shrinkage of the yarn or fabric is insufficient, and if it exceeds 30%, the texture tends to be stiff, which is not preferable. In addition, the shrinkage stress influences the ease with which a thread or fabric under restraint will shrink, and the higher the shrinkage stress, the more likely it is to shrink even under restraint. A shrinkage stress capacity of less than 30 mg/d is undesirable from this point of view, and a stress capacity of more than 300 mg/d is too sensitive to shrinkage due to the heat received by the fabric during the milling process, making it difficult to manage the process. , which is also unfavorable from the viewpoint of quality control between batches. Furthermore, the factors that influence the shrinkage include the blend ratio of animal hair fibers such as wool, product number, fiber length of animal hair fibers such as wool that make up the spun yarn, twist conditions of the spun yarn, and the fabric. There are different types, textures, densities, etc., and when these individual elements are combined, they exhibit a synergistic effect. However, in the synthetic fiber/animal hair blend fabric as in the method of the present invention, the shrinkage ability of the synthetic fiber is higher than that of the two-way blend. The so-called bulky structure as described above is an important factor in more effectively exhibiting the shrinking effect. In other words, when a synthetic fiber and an animal hair fiber are blended with a shrinkage ability necessary for concentrating the animal hair on the surface layer of the fabric in the heat treatment process, and the synthetic fiber is composed of one type of shrinkage ability. Comparing the shrinkage properties of fabrics with two types of shrinkage ability, the structure according to the present invention shows that the amount of animal hair fibers located in the surface layer of the fabric is the same, but the amount of animal hair fibers is the same. Since the restraint is gentle, the movement of the animal hair during the shrinking process is easy, and the felting progresses smoothly, resulting in good shrinking properties. According to the findings of the present inventors, in order to exhibit such an effect, the synthetic fibers should be a blend of two or more types, and the short fibers A of the synthetic fibers have a boiling water shrinkage capacity of 5 to 20%. Short fiber B has a boiling water shrinkage capacity of 10 to 30%, and the shrinkage stress of both short fibers A and B is
It is important to have 30-300 mg/d. When a milled knitted fabric is produced according to the present invention,
In the center layer of the knitted fabric, short synthetic fibers B
The composition ratio of synthetic fiber A is generally higher than the standard composition ratio in the middle layer, and the composition ratio of synthetic fiber A is generally higher than the standard composition ratio in the surface layer. This fabric tends to have a so-called three-layer structure. Therefore, the knitted fabric is made of animal hair fibers.
Almost the same texture as 100% milled knitted fabric,
At the same time, it has the characteristics of good pleatability due to synthetic fibers, high strength, and high durability. In the present invention, the copolyester fiber, acrylic fiber, and animal hair must be pre-dyed. Preferably, the copolyester fiber and acrylic fiber are tow-dyed. By combining such yarn dyeing and stretch-cut spinning, shrinkage properties are developed for the first time, and high value-added products can be obtained. The most preferable dyeing method for the tow dyeing is Vigoro dyeing. This allows a variety of colors to be combined, and although each single fiber has a different color, the fabric as a whole has the same color system, giving high-quality colors that cannot be obtained with piece dyeing. This is because it can be done. When trying to obtain a milled knitted fabric as described above using the spun yarn having the above-described fiber structure according to the present invention, polyester fibers are used as the short fibers A of the synthetic fibers, and polyester fibers are used as the short fibers B of the synthetic fibers. The combination of acrylonitrile fibers and wool as natural animal hair fibers is most effective and practical. In such a case, the polyester fibers consisting of short fibers A mainly contribute to imparting characteristics to the fabric by the synthetic fibers, and the polyacrylonitrile fibers consisting of short fibers B contribute to shrinking the fabric. The short fibers B are located in the center layer of a milled-like knitted fabric, and are generally a drawback for fabrics with a core, but due to the thermal properties of polyacrylonitrile fibers, they feel like a core in terms of fiber density. The degree becomes smaller. Therefore, the core becomes soft. As an example of the polyester fiber, by using a copolymerized polyester as described below, it can easily be made to potentially have the above-mentioned shrinkage ability and shrinkage generating stress ability. That is, polyethylene terephthalate fibers in which at least one of the following compounds (1) to (3) is copolymerized as the third component in an amount of 1.5 to 20 mol% of the total repeating units are suitable. Here, the first component means terephthalic acid, and the second component means ethylene glycol.
As the third component, the following are preferred. (1) Polyethylene terephthalate copolymerized with isophthalic acid. In this case, in addition to the isophthalic acid group, other quaternary
The components may be copolymerized within a range not exceeding 10 mol%. Examples of the fourth component include difunctional carboxylic acids such as adipic acid, sebacic acid, and naphthalene dicarboxylic acid, and diol compounds such as trimethylene glycol, diethylene glycol, polyethylene glycol, and 1,4-cyclohexanedimethanol. Can be mentioned. In the case of (1), it is preferable to copolymerize 3 mol% or more of isophthalic acid groups, preferably 4 to 10 mol%; if the copolymerization of isophthalic acid groups is less than 3 mol%, it is difficult to obtain large shrinkage performance. ,
If it exceeds 20 mol%, it will be difficult to obtain sufficient thread quality. (2) Polyethylene terephthalate copolymerized with 2,2-bis(4'-β-hydroxyethoxyphenyl)propane. In this case, in addition to 2,2-bis(4'-β-hydroxyethoxyphenyl)propane, another fourth component may be copolymerized within a range not exceeding 10 mol%. Such fourth components include isophthalic acid, adipic acid, sebacic acid,
Diol compounds such as naphthalene dicarboxylic acid, trimethylene glycol, and 1,4-cyclohexanedimethanol can be mentioned. In the case of (2), the copolymerization amount of 2,2-bis(4'-β-hydroxyethoxyphenyl)propane is 1.5 mol%.
If it is less than 20 mol%, it will be difficult to obtain the desired high shrinkage performance, and if it exceeds 20 mol%, it will be difficult to obtain sufficient thread quality. (3) Polyethylene terephthalate copolymerized with meta-sodium sulfoisophthalate. As the fourth component, adipic acid, sebacic acid,
2 such as isophthalic acid, naphthalene dicarboxylic acid, etc.
Functional dicarboxylic acids, trimethylene glycol, diethylene glycol, polyethylene glycol, diol compounds such as 1,4-cyclohexanedimethanol, monofunctional compounds such as benzoylbenzoic acid, benzyloxybenzoic acid, methoxypolyethylene glycol, glycerin In some cases, it may be desirable to copolymerize a trifunctional or higher functional compound such as trimellitic acid, pentaerythritol, etc. Note that the fourth component may be a mixture of two or more of the above compounds. In the case of (3), it is desirable to copolymerize 1.5 mol% or more of the meta-sodium sulfoisophthalic acid component;
The total copolymerization amount of the sodium sulfoisophthalic acid component and the fourth component is 2 mol% or more, especially 2.4 to 11
It is desirable that it is mol%. If it is less than 1.5 mol%, the shrinkage rate is difficult to increase, and if it is more than 20 mol%, properties other than the shrinkage rate may deteriorate, which is not preferable. As an example of the polyacrylonitrile fiber, it is preferable to use acrylonitrile obtained by copolymerizing acrylonitrile with 2 to 10 mol% of methyl acrylate and 0.1 to 5.0 mol% of sodium allylsulfonate. These fibers mentioned above preferably have the above-mentioned shrinkage ability and shrinkage stress ability, and conventionally, it has been very difficult to shrink synthetic fiber/wool blends, and it has taken a long time. Although this was thought to be necessary, by using such a composition of high shrinkage acrylic/medium shrinkage polyester/animal hair mixture, an extremely good shrinking effect can be obtained. The shrinkage rate due to hot water treatment (100℃) is determined by making a small reel with 10 turns using a lap reel with a frame circumference of 1m, determining the original length a of the sample yarn, and then applying hot water treatment (100℃).
After drying naturally for 24 hours, the length b is calculated using the following formula. Shrinkage rate (%) = a-b/a x 100 (%) Here, the sample yarn to be measured is a 100% synthetic fiber N _n = 2/52 (meter count) yarn used for measurement, and a The measurement load for and b is 200g. In addition, the shrinkage stress can be determined by attaching the other end to a strain meter and fixing the other end to a fiber that is kept at a constant length.
The material is placed in a hot water bath at .degree. C., the shrinkage stress generated is recorded on a recorder, and its maximum value (g/d) is determined as the shrinkage stress capacity. The polyester fibers or synthetic fibers such as polyacrylonitrile fibers used in the present invention are
The first drawn tow can be cut into short fibers either directly or after the second drawing by a cutting method, and the tow can be dyed. The fact that the starting raw material form of the synthetic short fibers is a primary drawn tow is thermally stable, and therefore has the effect of making it possible to stably perform the dyeing, chemical treatment, etc. In addition, even when the tow is subjected to secondary drawing, it is possible to maintain a high shrinkage level comparable to that of the primary drawn tow. It can be said that it is more practical. In the present invention, the mixing ratio of short fibers A of polyester-based synthetic fibers, short fibers B of acrylonitrile-based synthetic fibers, and animal hair fibers C is arbitrary, but from the viewpoint of texture etc., C is preferably 20 to 80% by weight. . If C is less than 20% by weight, the characteristics of animal hair fibers cannot be exhibited, and if it is higher than 80% by weight, the characteristics of synthetic fibers such as polyester cannot be exhibited. Further, the short fiber B of the acrylonitrile synthetic fiber is preferably 10 to 40% by weight. If B is less than 10% by weight, the shrinkage ability of the fabric will be insufficient and good shrinking property will generally not be obtained.If B is more than 40% by weight, not only will the properties of polyester and wool not be exhibited, but the fabric will form a core and become wind-resistant. harm the relationship. The characteristics of animal hair fibers are comprehensive characteristics represented by wool, such as heat retention, bulk, elasticity, tension/waist, resilience, and touch, while synthetic fibers have characteristics such as pleat retention, It refers to the overall characteristics of high strength/reinforcement, wrinkle resistance, durability, dimensional stability, washing resistance, and insect repellency. Of course, a small amount of other fibers may be mixed into the blended yarn or knitted fabric as long as the effects of the present invention are not impaired. A knitted fabric made using the blended yarn as described above is subjected to an appropriate finishing process as required, and then subjected to a fulling process. Preferred specific finishing processes are as follows. That is, as a finishing process, it is preferable to perform hot water shrinkage treatment under the following conditions before shrinking. The hot water treatment temperature is 60℃ or higher and 98℃ or lower, preferably 60℃
~90°C, most preferably in the range of 70°C to 90°C. Since this hot water treatment mainly causes contraction in the warp direction, it is desirable to use it under as low a tension as possible. Examples of the processing machine include a relaxer, a wince, and the like. Further, after drying, an intermediate setting is performed, and the temperature of the intermediate setting is preferably 150°C to 190°C. After that, it is subjected to a shrinking process. If the fiber shrinking process is performed without hot water treatment or intermediate setting, sharp wrinkles are likely to occur, which may impair commercial value. Furthermore, the step of performing greige setting in order to avoid such wrinkles is generally inappropriate because it may impair the high shrinkage performance of the synthetic short fibers. Preferably, after performing such hot water treatment and intermediate setting to shrink the fibers, the fibers are further subjected to finishing treatments such as napping, shearing, and steaming. Note that the shrinking process in the present invention is preferably carried out by the method and conditions generally used for wool, for example, in water at a temperature of 10 to 80°C, preferably 30 to 60°C, in the presence of a surfactant, the fabric is formed into small pores. This process involves rolling, pulling, and stretching the dough several times, essentially giving it the effect of kneading. According to the present invention as described above, synthetic fibers/
Even though animal hair blended yarn is used, it is possible to achieve extremely good shrinkage when producing milled-like knitted fabrics.In addition, by using synthetic fibers, it is possible to obtain 100% natural animal hair. A novel milled-like knitted fabric and a method for producing the same are provided, which can satisfactorily impart the characteristics of synthetic fibers, such as good pleatability, high strength, and durability, which cannot be obtained with conventional milled-like knitted fabrics. Hereinafter, the configuration and effects of the present invention will be specifically explained using Examples. Example 1 Modified polyethylene terephthalate copolymerized with 12 mol % of isophthalic acid was polymerized by a conventional method to form chips with an intrinsic viscosity of 0.505. After drying this chip under reduced pressure at 160℃, it is discharged from 300 holes with a diameter of 0.23mm, spun at 1200m/min, and converged to form 45
It was made into a tow of 10,000 denier. This tow is stretched at a temperature of 75
The stretched tow obtained by submerged stretching at 3.82 times the stretching ratio was dyed black. The dyeing conditions were 130°C x 60 minutes and a disperse dye was used. This tow is called "P-1". On the other hand, modified polyethylene terephthalate copolymerized with 5 mol % of isophthalic acid was polymerized by a conventional method to form chips with an intrinsic viscosity of 0.500. After drying this chip at 160℃ under reduced pressure,
It is discharged from a hole and spun at 1500 m/min, and converged to form a tow of 450,000 denier. This tow was stretched in liquid at a stretching temperature of 75°C and a stretching ratio of 3.82 times, and the drawn tow obtained was dyed black using a disperse dye at 130°C for 60 minutes. This tow is called "P-2". In addition, a copolymer consisting of 93.64 mol% acrylonitrile, 6.0 mol% methyl acrylate, and 0.36 mol% sodium allylsulfonate was spun by normal wet spinning, bundled, stretched, washed with water, batch-set at 113°C with moist heat, and then towed. And so. The tow was dyed red using a cationic dye at 100° C. for 60 minutes. This tow is called "Ac-1". Each yarn-dyed tow was subjected to secondary stretching in a tow reactor manufactured by O-M Manufacturing Co., Ltd., and then cut to form a sliver. The shrinkage characteristics of the single fibers of the obtained sliver were evaluated and were as shown in Table 1.

[Table] On the other hand, the undyed top of wool (Merino No. 64) is used as a sliver, and the basic blending rate is 50% synthetic fiber and 50% wool.
%, P-1: 50% and wool 50%, P-2: 50%
A spun yarn of N _n 2/52 (N _n : metric count) was made with a combination of three types: P-2: 30%, Ac-1: 20%, and wool: 50%. The spun yarn was skeined and subjected to hot water treatment at 90°C for 5 minutes. Table 2 shows the results of observing the blending ratio in each cross section of the surface layer, intermediate layer, and center layer of the treated yarn using an optical method.

[Table] The surface hue of the yarn after hot water treatment in Experiment No. 1 was whiter than that of the spun raw silk, and undyed wool fibers were concentrated in the surface layer. However, unevenness is observed in the yarn surface hue due to unstable spinning and drawing properties of P-1 tow. It can be seen that the yarn surface hue after hot water treatment in Experiment No. 2 had a smaller tendency to whiten than in Experiment No. 1, and the degree of concentration of wool on the surface layer was small. However, almost no hue unevenness in the yarn surface layer is observed. On the other hand, experiment number 3 according to the present invention
The yarn surface hue after hot water treatment was comparable to that of P-1/wool, with wool concentrated on the surface layer, and no uneven hue was observed, presenting a good surface condition. Example 2 Modified polyethylene terephthalate copolymerized with 12 mol % of isophthalic acid was polymerized by a conventional method to form chips with an intrinsic viscosity of 0.500. After drying this chip under reduced pressure at 160°C, it was discharged from 300 holes with a diameter of 0.23 mm and spun at 1200 m/min, which was converged to form tow of 450,000 denier. This tow is stretched at a temperature of 75
The stretched tow obtained by submerged stretching at a stretching ratio of 3.82 times at 3.82° C. was subjected to Bigolo printing consisting of black and white at a ratio of 1:1. This tow is called "PB-1". On the other hand, modified polyethylene terephthalate copolymerized with 5 mol% of isophthalic acid was polymerized by a conventional method to obtain an intrinsic viscosity.
I made it a 0.500 chip. After drying this chip under reduced pressure at 160°C, it was discharged from 300 holes with a diameter of 0.23 mm and spun at 1,500 m/min, which was converged to form tow of 450,000 denier. This tow is stretched at a temperature of 75°C.
The stretched tow obtained by submerged stretching at a stretching ratio of 3.82 times was subjected to Bigolo printing consisting of black and white at a ratio of 1:1.
This tow is called "PB-2". In addition, a copolymer consisting of 93.64 mol% of acrylonitrile, 6.0 mol% of methyl acrylate, and 0.36 mol% of sodium allylsulfonate was spun by normal wet spinning, bundled, stretched, washed with water, batch-set at 113°C under moist heat, and then towed. did. The tow was subjected to Bigolo printing consisting of black and white in a ratio of 1:1. This tow is called "AcB-1". Each tow subjected to Vigoro printing was subjected to secondary stretching in a tow reactor manufactured by OEM Seisakusho, and then cut into slivers. On the other hand, using the bigolo-printed top of wool (Merino No. 64) as a sliver, blend it with the following combination: N _n
The spun yarn was 2/52 (N _n : metric count). The results are shown in Table 3.

【table】

[Table] A 2/2 twill fabric was created using the spun yarn, and the fabric was washed at 40°C and then washed at 90°C.
Hydrothermal relaxation treatment was performed at ℃. The shrinkage rates of the gray fabric base at this time were as follows.

[Table] After drying, an intermediate setting was performed at 180°C, followed by a shrinking process for 60 minutes. The shrinkage rates after shrinking were as follows.

[Table] Next, the hair was brushed, sheared, and finished by steaming. The surfaces of the fabrics thus obtained are as follows: The fabric according to the present invention (Experiment No. 7) was almost entirely covered with wool, and had a uniform and fine milled tone (furano tone).
The fabric was excellent in both texture and appearance. Experiment No. 4: Although it was almost covered with wool and had a milled appearance, it was uneven and the quality was slightly inferior. Although the texture was good, core was observed and was not desirable. Experiment No. 5: The degree of shrinkage was poor, and it could not be described as a milled-like (furano-like) fabric, which was not desirable. Experiment No. 6: Appearance quality was almost the same as level 4, and the texture was also favorable. Experiment No. 7: Uniform shrinkage, a splendid milled-like (furano-like) appearance, and a good texture. Experiment Nos. 8 and 9...Although the texture was almost the same as Experiment No. 7, it was slightly inferior to Experiment No. 7 in terms of shrinkage and texture. However, something with commercial value was obtained. The reason why Experiment Nos. 6, 7, 8, and 9 according to the present invention exhibited such a uniform surface condition with excellent wool coverage was due to the moderate shrinkage on the fabric surface during the heat treatment process (relaxation treatment). It is thought that this is because the flexibility of the wool has been significantly improved by concentrating the wool and creating a yarn or fabric structure that does not restrict the wool during the shrinking process.
