Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for knitting a double-sided pile type long towel warp knitted fabric, which is a towel fabric most suitable for roll towels for towel cabinets installed in toilet rooms and the like.

In recent years, in order to improve the sanitary environment in the bathroom, many places are switching from short bath towels to long, seemingly endless roll towels for drying their hands after washing, and towel cabinet devices have become popular. gives the impression that it has become established in Japan. The main reason for this popularity was that with regular short towels, people had to wipe their hands again on the wet part after wiping, and there was a general need in society to eliminate this unsanitary problem.

The roll towels are usually 18cm to 30cm wide and long.
A long towel with a narrow width of 10 to 50 meters is wound into a roll. Conventionally, the material of this roll towel was
It was customary to be made of pileless fabric from 100% cotton yarn or a blend of cotton and synthetic fibers. cotton
The reason 100% woven fabric is used is because of its excellent water absorption properties. However, cotton has low tensile strength, and especially when the towel is manually pulled to expose a new towel surface, such as with rolled towels, the fibers may not be durable enough to repeat this pulling operation many times. An inconvenience occurred. Since roll towels are rented, they must be durable enough to withstand long-term use.
% toweling is difficult to fit. on the other hand,
When using cotton and synthetic fibers, there are few problems in terms of strength and durability, but the disadvantage is that the towels contain a considerable amount of synthetic fibers, which makes them poorly absorbent and reduces the towel's original water absorption function. . In addition, since none of the rolled towels had piles formed on the surface, they were inferior in feel when touched with the hand, that is, in terms of texture.

On the other hand, 100% cotton fabrics with pile on the surface are known as short bath towels. However, since it is a woven fabric, the pile easily comes off, and since the ground yarn and pile yarn are cotton, there is a problem in terms of strength.Furthermore, there are problems when manufacturing pile cotton towels using a warp knitting machine. When making a 100% cotton towel into a long length for use as a roll towel, it was impossible to apply tension to the towel with a roller because it was extremely weak in the longitudinal direction, so it was impossible to make it into a long length.

The present invention has been made to improve the above-mentioned drawbacks, and it improves the texture by forming front piles and back piles on the upper and lower surfaces of the ground fabric formed from chain yarns and inserted yarns, and also allows the pile to come out of the ground fabric. The chain yarn and insertion yarn are made of synthetic fibers to give strength in the longitudinal and width directions of the towel and improve durability, making it especially suitable for rental roll towels. The purpose of the present invention is to provide a method for knitting a double-sided pile type long towel warp knitted fabric that maintains water absorption by composing the pile yarn with 100% cotton yarn.

EMBODIMENT OF THE INVENTION Hereinafter, an embodiment of the method for knitting a double-sided pile type long towel warp knitted fabric according to the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a longitudinal cross-sectional view of a warp knitting machine used to carry out the method of the present invention, in which a front pile yarn guide 1, chain yarn guide 2, insertion yarn guide 3, and back pile yarn guide 4 are shown. They are attached to guide bars 5, 6, 7, and 8, respectively. Each guide 1, 2, 3, 4 is driven by each guide bar 5, 6, 7, 8 to move back and forth and left and right. 9 is a sinker, and a needle 10 is configured to be able to move up and down between the sinkers 9. Reference numeral 11 denotes a sheaver, which operates so that when the tip of the needle 10 captures a thread, the thread is successfully separated from the tip.

FIG. 2 is a simplified configuration diagram showing the relative relationship between needle rows and guide rows, in which needles N ₁ to _{N 5} are arranged in a row, and the four guides 1 and 2 are arranged at every other needle. , 3, and 4 are arranged in a row as a guide row. The front pile yarn S 1 is attached to the front pile yarn guide ₁ , and the chain yarn S ₂ is attached to the chain yarn guide 2.
However, the insertion thread S3 is threaded through the insertion thread guide ₃ , and the back pile thread S4 is threaded through the back pile thread guide ₄ . Therefore, the needle N ₃ also has N ₅
Also, four guides are threaded and arranged. However, needles N ₂ and N ₄ are not provided with guides.

In this embodiment, nylon filament yarns are used as the chain yarn S ₂ and the insertion yarn S ₃ , but other synthetic fibers such as polyester and others may also be used. In particular, since chain yarn is a material that determines the tensile strength in the longitudinal direction of the towel, various synthetic fibers with high tensile strength must be selected. This is because the insertion thread S ₃ is made of synthetic fiber, so in the case of a towel, it is also pulled in the width direction when wiping. Further, the front pile yarn _S1 and the back pile yarn _S4 are made of pure cotton (100% cotton).

As will be described later, the pile is the part that floats on the surface of the towel and comes into direct contact with people's hands, so it is necessary to use highly absorbent fibers that absorb water from the hands. Therefore, pure cotton yarn is optimal.

FIG. 3 is an organization chart showing an embodiment of the present invention. N ₁ to _{N 6} correspond to the needle arrangement of FIG. 2 described above. 0 to 6 indicate the distance between the needles. T ₁ to _{T 6} indicate the rising positions of the needle, and for example, the time difference between the positions T ₁ and T ₂ gives the period required for the needle to perform one round trip of rising and falling.

First, at the raised position T ₁ of the needle, the chain thread S ₂ is overlapped 1-0, 3-2, 5-4 with respect to every other needle N ₁ , N ₃ , N ₅ , and The front pile yarn S ₁ is knitted so that the chain yarn S ₂ forms a loop around the overwrapped needle so that the front pile yarn S 2 will not be overwrapped. At the same time, the back pile yarn _S4 is overlapped with needles _N2 , _N4 , and _N6 having no guides so as not to form a loop, and this portion is raised and becomes a back pile B. The inserted yarn _S3 is 0- across the three stitch rows of the chain yarn _S2 .
It is underwrapped with 5. At the next needle raising position _T2 , the chain thread _S2 is 0-1, 2-3,
4-5 and the needles N ₁ , N ₃ , N ₅ , and the front pile yarn S ₁ is wrapped over the left adjacent needles N ₂ , N ₄ which do not have a guide so as not to form a loop. , this part is raised and becomes the front pile F. Also, the back pile yarn _S4 is overwrapped in such a way that the needle without a guide on the left side and the chain yarn _S2 between the needle without a guide on the left side form a loop in the overwrapped needle. It is knitted and fixed within the stitch row,
The back pile B is longer than the front pile F. The inserted yarn _S3 is underwrapped with 5-0 to knit three stitch rows. After T ₃ , the formation states of T ₁ and T ₂ are simply repeated.

In Figure 3, not all the threads are shown. The solid lines indicate each of the yarns S ₁ to _{S 4} , and the dotted lines indicate the second front pile yarn and back pile yarn. This knitting structure spreads vertically and horizontally to form a double-sided pile type long towel warp knitted fabric.

When the long towel warp knitted fabric is knitted as shown in Fig. 3, the front pile F is formed of the front pile yarn _S1 and the front pile is formed of the back pile yarn _S4 as shown in Fig. 4A. The back pile B, which is longer than the pile F, protrudes from one side of the ground structure C formed by the chain yarn _S2 and the insertion yarn _S3 . Therefore, by applying brushing with a roller brush (not shown) from the non-protruding side of the pile of this warp knitted fabric, the front pile F, which is shorter than the back pile B, protrudes to the opposite side and rises, as shown in Fig. 4B. The state shown is shown.

Figure 5 shows a perspective view of the roll towel.
The double-sided pile type long towel warp knitted fabric shown in Figure 4B is wrapped into a roll towel, and can be used as a roll towel 14 to be installed in a towel cabinet normally installed in a toilet. .

As described in detail above, the present invention has piles on both sides, giving it a good texture and feel.Moreover, since the piles are made of pure cotton yarn, it has extremely good water absorption when wiping wet hands. Because of this, it is difficult to escape from the ground organization. On the other hand, the chain threads and insertion threads are made of synthetic fibers, so they have sufficient strength even when the towel is stretched a little, and they are also durable enough even when renting a roll towel and using it many times. are doing.

In addition, even when continuous production is performed on a warp knitting machine as a long product, since the chain yarn is a synthetic fiber, it has sufficient strength even when tension is applied with a roller, and the manufacturing method of the warp knitted towel fabric is suitable for long roll towels. We have provided the best possible solution.
