Description

Pile yarn and its manufacturing method {PILE YARN AND THE METHOD FOR MAKING IT}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to pile yarns, and more particularly, to pile yarns used for weaving fabrics used for highly curved objects such as covers or curtains for sofas or interiors for automobile interiors, such as sheet or door trim of automobiles. It is about. The present invention also relates to a method for producing such pile yarns.

Typically, pile yarns used for weaving fabric fabrics used for interior materials of automobiles, such as car seats or door trims, and for curved shapes such as covers or curtains for sofas, or interiors, are not circular but flat. Because of the shape, the surface of the fabric after the weaving of the fabric has a disadvantage that the surface looks clean due to the reflection of light, there is a drawback that the pile of the pile yarn when the fabric is used. In addition, the conventional pile yarn shows that the surface of the fabric is rough due to the shrinkage of each pile, because the pile uses acrylic or polyester stretching (DTY), and the fabric woven with such pile yarn has a static load elongation of 10% or less. For example, there is a flaw that does not meet the static load elongation of 15% or more required when used in a bent object such as the interior of the car, such as the seat of the car or the door trim, there is a defect that wrinkles when used in the object as mentioned above.

In the conventional manufacturing process of such a conventional pile yarn, as shown in Fig. 3, two strands of screening (polyester DTY, 150D / 48F) (1) is firstly twisted (first twisting step, S 700 times). (2), the second step (secondary step, Z 500 times) (3) to supply the pile (polyester DTY, 150D / 48F) to be fed with the screening, forming a skein in the hanger (Skin forming step) (4), the step of winding the dyeing step (5) of dyeing the skein of pile yarn at 130 ℃ consists of a process to obtain a pile yarn finished product.

Since the pile yarn produced by the prior art pile yarn manufacturing process is a polyester stretched fabricator (DTY), shrinkage occurs after heat treatment of the fabric fabric so that the surface of the fabric fabric becomes rough, the pile is easily removed from the screening, and the pile and the pile are easily All of them are polyester stretched, so when weaving fabrics using them, the static load elongation is less than 10%, which causes wrinkles when working on finished products.

In the present invention, the present invention was made in view of the above-described problems, and the file is prevented from being pulled out from the screening, and by using the file of the low-wound yarn, the surface of the fabric is prevented from being rough, and a static load elongation of 15% or more can be obtained. Provide pile yarn. In addition, the screening is pre-dyed and the pile is made of doped dyed yarn to provide pile yarns with high daylight fastness. The present invention also provides a method for producing such pile yarns.

To this end, in the present invention provides a pile yarn in which the file is interlaced in the yarn to be twisted, the yarn is a stretch processing selected from polyester yarns or nylon yarn and the polyester stretch processing or polyester low-strength yarn with the heat treatment set It is characterized in that it is composed of fused with a low-melting nylon yarn fixing the file to the screening.

In addition, the present invention provides a method of manufacturing a pile yarn in which the file is interlaced in the screening, the method of the present invention comprises the steps of dyeing the screening selected from polyester yarns or nylon yarn, the first step of the dyeing screening, Secondary stages of obtaining the pile yarns by supplying files of low melting point nylon fusion yarns and low-strength yarns to the primary yarn screening, which causes the piles to be interlaced between them and the piles are interlaced, and heat-setting the pile yarns. It is characterized by consisting of steps.

Referring to the present invention in more detail based on the accompanying drawings as follows.

1 is a process diagram of the present invention.

2 is a cross-sectional view for schematically illustrating a pile yarn manufactured according to the present invention.

The pile yarn 10 of the present invention is composed of a screening 12 and a pile 14 similarly to a conventional pile yarn.

1 shows a process diagram of the present invention. In the process diagram of FIG. 1, the screening 12 is selected to have a 20S thick polyester spun yarn so as to increase the friction force with the pile 14 so that the pile does not fall out. Are stained (step 100). In addition, the screening 12 may be 210D nylon yarn to increase the static load elongation of the finished fabric fabric by shrinkage by heat treatment after weaving the fabric fabric. The pile 14 is a polyester yarn for improving daylight fastness, and a polyester low crimp yarn is used so that shrinkage does not occur during heat treatment of the fabric. In addition, the pile 14 may be a polyester stretching of 150D / 48F which is a high winding house. In this case, the polyester drawing process is heat-treated twice at 130 ° C. for 20 minutes in order to minimize shrinkage during heat treatment of the fabric.

The judging 12 is first-twisted in the Z direction 500 times only with the judging 12 before the file 14 is deadlocked (step 102).

The primary twisted screen 12 as described above is supplied with interlaced piles 14 selected from polyester low-stretch yarns or heat-treated polyester drawing processes as mentioned above, and additionally, fusion yarns 16 are supplied with S Secondary firing is performed in 540 directions (step 104).

Here, the fusion yarn 16 is a nylon yarn of 70D is used, and two strands are supplied to the screening 12 to be twisted together with the screening 12. Fusion yarn 16 composed of low-melting nylon yarn is the adhesive to prevent the pile 14 from falling out of the screening 12 by fixing the pile 14, which is melted in the subsequent heat treatment process and stuck to the screening 12. Do it.

In the second continuous yarn step 104, the pile yarn 10 is substantially completed, which is formed through the skein forming step 106 in the hanger. After that, the pile yarn 10 formed as a skein is set by heat treatment at a temperature of 95 ~ 98 ℃ in the heat treatment step (108). In the heat treatment step 108, the nylon fusion yarn 16 that is twisted together with the screening 12 is melted to fix the dead file 14 that is interlaced with the screening 12. Thereafter, in the winding step 110, the finished product pile yarn 10 is obtained.

2 is exaggeratedly expressed to explain the pile yarn 10 manufactured as described above.

As such, the present invention prevents the surface of the fabric fabric from being rough by using a low crimp yarn in the pile 14, and there is no shrinkage after weaving the fabric fabric so that the surface is smooth and smooth. In addition, in the case of the examination 12, this can be dyed in advance, and the pile 14 can provide a pile yarn having a high daylight fastness by using an original yarn. The pile 14 can be fixed in the state of being interlocked with the screening 12 by melting of the low melting point nylon fusion yarn 16 that is twisted together with the screening 12 so that it can be prevented from being pulled out of the screening 12. In particular, the screening (12) is used to stretch polyester yarns or nylon yarns to increase the static load elongation of pile yarns by more than 15%.

As described above, the present invention provides a pile yarn which prevents the pile from falling off from the screening and prevents the surface of the fabric from being rough by using the pile of the low-wound yarn and obtains a static load elongation of 15% or more. In addition, the screening is pre-dyed and the file is made of original yarn, providing a color yarn with high daylight fastness.
