Description

Description: TECHNICAL FIELD The present invention relates to high density fabrics. More specifically, the present invention relates to a high-density woven fabric that is thin and light, has high tear strength and good waterproof performance (water pressure resistance).

BACKGROUND ART Conventionally, high-density woven fabrics have been widely used as general garment materials requiring waterproofness, as sports garment applications, or as garment materials for lining of futons.

In particular, in the use of sports clothing, with the spread of outdoor sports, its demand is increasing year by year, and the demand for improved waterproofness is increasing.

In order to meet such demands, by reducing the single fiber fineness of the constituent yarn or by increasing the weaving density,
Various methods have been proposed for increasing the denseness of a woven fabric.

For example, in U.S. Pat.No. 4,548,848, a long fiber yarn having a single fiber fineness of 1.2 denier or less is used for warp and weft, and the total cover factor in the warp and weft directions is 1400.
A high density waterproof fabric of ~ 3400 is disclosed.

Japanese Patent Application Laid-Open No. 2-216238 discloses a structure in which either the warp or the weft has a higher woven crimp rate than the other, and yarns in a direction orthogonal to the yarn having the higher crimp rate overlap each other. A high-density woven fabric having the following is disclosed.

However, in the above two prior art woven fabrics, the woven density of only either the warp or the weft is increased, so that the balance of the warp / weft is poor, and after the fabric is subjected to a water-repellent treatment, When used as a waterproof fabric,
There was a problem that the water pressure required for practical use (1000 mm water column) was not satisfied.

In the past, when the density of the woven fabric was increased, the binding force of the warp and the weft was increased, and the deviation of the yarn was less likely to occur, so the tear stress at the time of tearing was concentrated on a small number of yarns,
It has been said that the apparent tear strength of the fabric is rather reduced (for example, edited by the Japan Textile Machinery Society, Industrial Materials Research Group,
“Handbook of Industrial Textile Materials”, page 24, Figures 1 and 17).

In particular, when the total fineness of the constituent yarns is reduced in order to enhance the denseness of the woven fabric, this phenomenon is conspicuous, and it has been difficult to obtain practically no problem tear strength in a high-density woven fabric.

That is, heretofore, it has not been possible to obtain a high-density woven fabric having high water pressure resistance while maintaining a practically no problem tear strength, in other words, a high-density woven fabric having both high tear strength and water pressure resistance.

DISCLOSURE OF THE INVENTION An object of the present invention is to provide a high-density woven fabric that overcomes the above two trade-offs and has good waterproof performance without lowering tear strength.

The present inventors have conducted intensive studies to solve the above problems, and as a result, when weaving a high-density woven fabric, when keeping the overlap of the warp and weft constituting the woven fabric in a certain relationship, there is no decrease in tear strength. It has been found that a high-density woven fabric having high water pressure resistance can be obtained.

Thus, according to the present invention, the same or different long-fiber yarns, in which at least 40% by weight of the constituent yarns are occupied by single fibers having a single fiber fineness of 1.1 denier or less and whose total fineness is 120 denier or less, are warp and weft, respectively. in the high-density woven fabric arranged, each section overlapping coefficients W _p and W _f of the warp and the weft constituting the woven material is satisfies the following (a) and (b) at the same time, and fabric through and weft direction A high-density woven fabric characterized by having a tear strength of 1000 g or more is provided.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.

In the warp and the weft constituting the high-density woven fabric of the present invention, 40% by weight or more, preferably 65% by weight or more of the constituent yarns are occupied by single fibers having a single fiber fineness of 1.1 denier or less, preferably 0.5 denier or less. In addition, it is assumed that the long fiber yarn has a total fineness of 120 denier or less, preferably 100 denier or less. On the other hand, the lower limit of the single fiber fineness is preferably 0.02 denier, and more preferably 0.05 denier. Further, the lower limit of the total fineness is preferably 10 denier, and more preferably 20 denier.

The composition ratio of fibers with a single fiber fineness of 1.1 denier or less is 40
If it is less than 100% by weight, or if the total fineness exceeds 120 denier, the denseness of the fabric will decrease and the water resistance will decrease, and the texture will be hard, making it unsuitable for clothing applications where waterproofness is required. .

The monofilament fineness of the other fibers constituting the portion of less than 40% by weight of the long fiber yarn is preferably more than 1.1 denier and not more than 3 denier, more preferably more than 1.1 denier and not more than 2 denier.

Examples of the long fiber yarn include a multifilament flat yarn of a thermoplastic synthetic fiber, a false twisted yarn, and a mixed fiber consisting of two or more types of multifilaments having different physical properties.

The long fiber yarns constituting the warp and the weft may be the same or different.

The cross-sectional overlap coefficient W _p and W _f warp and weft constituting the dense fabric of the present invention needs to satisfy the following (a) and (b).

(A) 1.30 ≧ W _p ≧ 1.10, preferably 1.30 ≧ W _p ≧ 1.15 (b) 1.20 ≧ W _f ≧ 0.85, preferably 1.20 ≧ W _f ≧ 0.90 where the cross-section overlap coefficients W _p and W _f are Is defined as

W _P = W _1f / W _0f W _f = W _1p / W _{0p In} the above equation, W _0f , W _1f , W _0p and W _1p are defined as follows.

W _0f : the width occupied by the minimum repeating unit in the cross section of the woven fabric along the bisection line in the length direction of an arbitrary weft in the minimum repeating unit of the woven fabric, for example, two warps in the case of a plain woven fabric, 2 /
In the case of 2 twill weaves, it means the width occupied by 4 warp threads and in the case of 5-sheet satin, 5 warp threads. However, the width is an average value of three different minimum repeating units.

W _1f : refers to the sum of the widths of the warps included in the minimum repeating unit in the cross section of W _0f . However, the sum of the widths is an average value in three different minimum repeating units.

W _0p : width of any warp in the minimum repeating unit of the woven fabric in the cross section of the woven fabric along the bisection line in the length direction, occupied by the minimum repeating unit, for example, two warps in the case of plain weave, 2 /
In the case of 2 twill weaves, it means the width occupied by 4 warp threads and in the case of 5 sachets, 5 warp threads. However, the width is an average value of three different minimum repeating units.

W _1p : Sum of widths occupied by each weft included in the minimum repeating unit in the cross section of W _0p . However, the sum of the widths is an average value in three different minimum repeating units.

For example, FIG. 1 is a cross-sectional view of a plain woven fabric in a direction perpendicular to the warp, for explaining the cross-sectional overlap coefficient of the warp.
_0f the maximum width of two per warp is the smallest repeating unit of plain weave, also W _1, W ₂ represents the maximum width of warps contained in said repeating unit, W _1f by W _1f = W ₁ + W ₂ is Desired.

Sectional overlap factor W _f of the weft yarn is also obtained by the same method as W _p from the direction of the fabric cross-section perpendicular to the weft.

Figure 2 is a graph showing the relationship between W _p and W _f, dense fabric of the present invention have a W _P and W _f in the range of C of FIG. 2.

In other words, the high-density woven fabric of the present invention is 40% by weight of the constituent yarn.
The above is occupied by monofilaments having a single fiber fineness of 1.1 denier or less, and using a long fiber yarn having a total fineness of 120 denier or less, W
Due to the control the value of _p and W _f in the range of C of FIG. 2, has a sufficient compactness in both the warp direction and the weft direction, and for over / weft balance is good, high Has water pressure resistance.

In contrast, conventional high-density woven fabrics including the aforementioned U.S. Pat. No. 4,548,848 and the woven fabric disclosed in Japanese Patent Laid-Open No. 2-216238 mainly increase only the warp density to increase the density of the entire woven fabric. For example, _p and _Wf were in the region A in FIG. 2, and the denseness of the woven fabric, particularly the denseness in the weft direction, was insufficient, and a sufficient water pressure was not obtained.

The reason is that it is technically difficult to increase the weft density of the woven fabric, and in the conventional method, if the weft density is to be increased, the warp density will be greatly reduced. In this case, W _p and W _f shifts to the region of the example of FIG. 2 B.

Therefore, conventionally, only the density of either the warp or the weft can be increased, and a woven fabric having sufficient denseness in both the warp and the weft as in the high-density woven fabric of the present invention has not been obtained.

In the present invention, by setting _Wp and _Wf in the above ranges, a sufficient water pressure can be imparted, and the total fineness is 12
Despite using a long fiber yarn of 0 denier or less, the tear strength of the woven fabric can be maintained at a high level.

That is, in the high-density woven fabric of the present invention, since adjacent warp yarns (and weft yarns) overlap each other, many yarns are simultaneously subjected to a tearing stress, and the tearing force required to break the yarns is reduced. As a result, the apparent tear strength, which has been decreasing with the increase in density, greatly increases in both the warp and weft directions.

In the present invention, there is a portion where the wefts do not overlap with each other (a portion of 0.85 ≦ W _f ≦ 1.0), but since the warp tension is extremely high as described later, the warp becomes integral with the weft and the tearing force is increased. Therefore, it was confirmed that the tearing strength could secure 1000 g even in this part.

Because, in the case of normal warp tension (W _f is less than 0.85), a gap 4 is formed between the adjacent warps 1 and 2 and the weft 3 as shown in FIG. In contrast to the independent behavior, the warp tension is extremely high in the present invention, so that the voids 4 hardly exist as shown in FIG. 3 (b), and the warp and the weft behave integrally. .

Such knowledge was first discovered by the probability of the weaving technique described below, which maximizes the overlap of warp (weft) yarns in high-density woven fabrics. It has become possible to obtain a high-density woven fabric having a high water pressure without lowering the strength.

Furthermore, even if W _p and W _f satisfy the above-mentioned values, (W _p −
If the value of W _f) exceeds 0.3 (to a range of C ₂ in FIG. 2) is subjected / weft balance of the fabric is slightly disturbed, because the water pressure resistance and tear strength tends to decrease, (W _p - W _f ) is 0.3
The following is preferably (the range of C ₁ of FIG. 2).

The long fiber yarn used in the high-density woven fabric of the present invention is preferably a multifilament formed from polyester, and the polyester is a polyester having an ethylene terephthalate unit of 80 mol% or more of all repeating units. Is advantageous.

As a method for obtaining the high-density woven fabric of the present invention, for example, 40% by weight or more, preferably 65% by weight or more of the constituent yarn is occupied by single fibers having a single fiber fineness of 1.1 denier or less, preferably 0.5 denier or less; Total fineness is 120 denier or less,
Preferably, a polyester multifilament flat yarn of 100 denier or less is placed on each of the warp and the weft, and the tension of the warp is increased to twice or more of the conventional (at most 0.3 g / denier), and the warp and weft cover factors (CF )
Is obtained by weaving with a total of 1800 to 3500.

Here, the cover factor (CF) is a value determined based on the following equation.

In the above formula, n indicates the number of warps or wefts per inch of the fabric, and de indicates the denier of the warp or weft of the fabric.

The fabric of the present invention has a total cover factor (CF) in the warp direction and the weft direction in the range of 1800 to 3500, preferably 2000 to 3500.

At this time, the number of twists of the multifilament yarn used is
The flat yarn is preferably 300 T / m or less, and more preferably a substantially untwisted flat yarn.

Here, the substantially non-twisted state refers to a state in which active twisting with twisted yarn or the like has not been performed and only unintended twisting such as untwisting has been applied.

The multifilament yarn may have a crimp by false twisting or the like. For example, two or more types of multifilaments having different heat shrinkage rates may be aligned and mixed by a known means such as twisting or air entanglement. It may be delicate.

As a method of increasing the tension of the warp, a method of increasing the winding speed difference between the back roller and the press roller of the loom can be adopted.

FIG. 4 schematically shows an example of the structure of a loom for weaving the high-density woven fabric of the present invention by increasing the warp tension, wherein 5 is a beam, 6 is a back roll, 7 is a warp, 8 Indicates a heald, 9 indicates a reed, 10 indicates a press roll, and 11 indicates a cross roll.

In the present invention, the diameter of the back roll 6 and the press roll 10 is set to, for example, 1.5 times or more the normal diameter (at most about 100 mm), and the difference in the winding speed between the two rollers is increased so that the rolls can be wound without slipping. , The tension of the warp 7 is increased.

The value of the tension may be appropriately set according to the fineness and the weaving density of the multifilament to be used.
0.35 to 0.9 g / denier, preferably about 0.4 to 0.7 g / denier is required.

As described above, increasing the weft density of a woven fabric is technically more difficult than increasing the warp density.

In other words, in order to increase the weft density, it is necessary to increase the number of driving yarns.However, if a normal loom is used, loosening of the warp after beating occurs, etc. Physical limitations arise.

On the other hand, in the present invention, the warp tension is increased to a level far exceeding conventional common sense and the weft is driven in a state where the warp is stretched, so that the warp does not loosen and the balance of the warp / weft is maintained. It is possible to increase the density of the woven fabric.

The loom used in the present invention is not particularly limited, and a water jet loom or an air jet loom can be used in addition to a normal loom.

In addition, there is no restriction on the weaving structure.
Any organization such as a satin organization can be adopted.

It is preferable that the woven fabric after weaving is subjected to scouring, relaxation, presetting, dyeing, and, if necessary, water-repellent treatment followed by calendering.

In the water-repellent treatment, a fluorine-based or silicon-based water-repellent may be applied by a method such as a spray method, a padding method, or an immersion method. At this time, the amount of the water repellent attached to the fabric is preferably 15 to 80% by weight.

It is also preferable to add a permeability improver such as isopropyl alcohol to the treatment bath, or to increase the treatment time longer than in the case of ordinary fabrics to increase the penetration of the water repellent.

The high-density fabric thus obtained has a tear strength of 1000 g or more in both the warp and weft directions, far exceeding that of conventional high-density fabrics, and has a high water pressure of 1000 mm water column or more after the water repellent treatment. Is shown.

As described above, the high-density woven fabric of the present invention is characterized in that it has a sufficiently high water pressure resistance based on the structure of the woven fabric without forming a water-repellent coating on the fabric surface.
