Description

DETAILED DESCRIPTION OF THE INVENTION The present invention also relates to a method of overprinting fine partial prints on the entire surface in a darker color than ground dyeing and then raising the fabric to obtain a marbled raised fabric with a three-dimensional effect.

1- Conventionally, various methods have been proposed for imparting marbled patterns to brushed fabrics made of long fibers. For example, the so-called undyed method involves dyeing the yarn in spots, weaving it, and then raising it to obtain a marbled-like raised fabric.However, this method increases the cost due to the increased number of steps, and also increases the product quality. It has the disadvantage of large variations in quality. In addition, a different color dyeing method is often used that uses a mixture of two types of fibers with different dyeability to weave, then dyes and raises them to create a marbled pattern, but the dyeing process depends on the properties of the fibers. It is necessary to use different dyeing methods and dyes depending on the type of fiber, and there are also problems with fastness due to the difficulty of removing contaminated dyes, and finishing conditions to improve dimensional stability etc. Currently, it is not possible to finish the material under sufficient conditions due to the need to match the properties of the material.

Another way to create a marbled pattern is to use printing technology to dye the fabric before or after raising it, but even though it is an easier method in terms of process, printing it after raising the cloth is a method. It is assumed that the three-dimensional effect of the marbled pattern would be lacking.

Before raising, there were many problems as to what type of - should be printed to obtain the marbled pattern seen on woolen fabrics, etc.9, so this practice was rarely done at present.

In addition, in a raised fabric that uses ultrafine fibers of 1 d or less and most of the ultrafine fibers are present on the raised surface, it is difficult to produce a marbled woolen fabric without losing the soft feel of the ultrafine fibers or the chalk marks. Applying the undyed method or different color dyeing technology does not solve the problem easily, because in the process of manufacturing and weaving fibers of 1 d or less, even if you try to apply the undyed method, the fibers will be thin and may become single fibers. Due to the large number of yarns, it is difficult to handle them in the undyed process, and undying them in a ready-to-weave state is currently not being adopted due to productivity and product quality concerns. be. In addition, when trying to apply the different color dyeing method to these ultrafine fibers of 1 d or less, there is another technical difficulty. In other words, when different fibers are blended in the short fiber state, they cannot be spun because they are too thin, and when trying to mix them into filament F, both of the different fibers must be 1 d or less.
There are disadvantages that the finished feel of the brushed surface is not utilized, resulting in a rough and hard texture, and that only the thicker fibers are brushed first9. Even if you think about it, it is necessary to manufacture both types of ultra-fine fibers using advanced technology, and it is necessary to mix the filaments in appropriate bundles to prevent filaments from being cut. Currently, it has not been adopted due to the quality of the product and the thinness of the fibers, so even if mixed fibers are dyed in different colors, they will look plain, and when twisted as double yarns, etc. It becomes difficult to raise the hair.

There is a weaving technique that alternately inserts different types of fibers into the weft, but due to differences in shrinkage and differences in the difficulty of raising, dense raising cannot be achieved, and even if dyed with different colors, a product with a marbled tone and a natural three-dimensional effect cannot be obtained. Even with ultrafine fibers, there were many problems, especially when the fibers were less than 5 d, a woolen fabric with a harmonious marbling could not be obtained.

The present invention was made in view of the current situation.

By adopting print dyeing technology, which has not been widely used in the past, and making several improvements, we have developed a method to easily obtain marbled harmonious woolen fabrics, in which most of the ultra-fine fibers are on the raised side, with good productivity and high quality. The purpose is to provide the following. In order to achieve this object, the present invention has the following configuration. That is, in the present invention, the warp has a total denier of 50 to 150 d, and the filament fineness is 1.
It is a false twisted yarn consisting of ~5d, and the weft has a total denier of 5.
The first step is to dye 4 to 8 double-sided satin fabrics made of filament yarns with i1 to 150 d and filament fineness of 1 d or less.
Step 2: Partially dyeing small patterns on the entire surface of the ground-dyed fabric so that the color is darker than the ground-dyed phase and the area is 60 to 70% of the ground-dyed area; 6th step, where the fabric is raised on both sides. This is a method for producing a woolen fabric with a smooth texture.

Below, nine aspects of the present invention will be explained in detail.

In the method of the present invention, mainly polyester fibers are preferably used from the viewpoint of product durability, texture, etc., but synthetic fibers such as polyamide fibers and polyacrylic fibers may also be used. The total denier for the warp is 50 to 15.
Filament fineness 1, which is often used for general clothing with 0d
-5d, and it is preferable to use a false twisted yarn to improve the texture.

For the weft, use a filament yarn with a total density of 50 to 150 (1, filament fineness of 1 d or less).

Preferable in terms of strength and finger marks. When weaving using these yarns for the warp and weft, weft satin fabric is woven to facilitate napping. 4 to 8 pieces of satin, especially 5 pieces of satin, are good for product stability, especially ease of napping (1) maintaining strength (9) improving fluff density; May be brushed. There is no need to brush the surface of the back side. This double-sided satin fabric is refined if necessary, and then ground-dyed using a disperse dye in a light to medium color. The first step to dye this ground dye
After the process, background dyeing overprinting is performed to obtain the marbled pattern of the present invention. That is, a second step is carried out on the ground-dyed fabric, in which the entire fine pattern is partially dyed in a darker color than the ground-dyed phase and with a print area of 30 to 70% of the ground-dyed area. One of the important points of the present invention is that the background dyeing in the first step must not be a dark color, such as dark blue or black, because of the necessity of overprinting in the second step. The second step is the most important step in the present invention in order to obtain a marbling tone in the subsequent raising step. The reason why the color is darker than the ground dyeing is to express the marbled shading.

The same reason is why the print area is set to 30 to 7096 times the ground dyeing area.If the overprint area is 50% or more of the ground dyeing area, the color tone of the ground dyeing will be strong and a sufficient marbling effect will not be obtained. Also, the overprint area is 7
This is because if it exceeds 0%, the density of the overprint will be too strong, resulting in a plain color tone. Therefore, in order to express marbled shading, it is most suitable for the printing area to be 50 to 70% of the background dyeing area. Printing involves partial dyeing of minute patterns on the entire surface of the background dyeing, but minute patterns mean dots or short lines, and nine dots are the kind that can be created when a dye solution is sprayed onto the dye. For large pieces, it is desirable that the diameter is about 1 mm or less, and for linear pieces, the width is about 1 fl and the length is 3 to 10 mm.
The shape may be about the size of a fin, or it may be a linear combination of shapes such as shi, mouth, or thousand. It may also be a combination of dots and lines, or similar trees and leaves, flowers and leaves, triangles, squares, etc. alone or in combination. It is desirable that the entire fine pattern in the second step is large enough that the shape of the pattern itself will not remain in the brushing process performed in the next sixth step. cannot achieve its purpose. A dotted, all-over micro pattern can be created using a roller print method using a commercially available speck dye, but it is preferable that the size of the speck after dyeing be close to 1n, and if the size of the speck is about +0.1am, it will not be possible to create a speckled pattern after raising. The color will be plain and you will not be able to get a marbled pattern. After the second process.

By using a needle cloth raising machine or the like to mainly raise the overprint surface until there are no dotted or linear patterns, a marbled-like raised fabric with deep and light shading and a three-dimensional effect can be obtained. After this sixth step, finishing agents such as urethane resin, softener, and antistatic agent are applied as needed. In the sixth step, the back side is also slightly raised, which improves the texture and feel of the fabric, resulting in a high-quality marbled-like raised fabric.

Next, the method of the present invention will be explained with reference to Examples, but the present invention is not limited thereto.

Example 1 Using polyester false twisted yarn 75d156f (filament fineness approximately 2d) for the warp and polyester filament yarn 110d/400f (filament fineness approximately 0.5d) for the weft, weaving was performed on both sides with a weaving date of approximately 140Q/d. Five pieces of satin fabric were woven. The warp density after weaving is 11
The weft density was 164 yarns/inch. Next, it was relaxed and refined using a jet dyeing machine, and then the first step of gray machine ground dyeing was carried out using a disperse dye under the conditions of dyeing recipe 1 below.

Dyeing Recipe 1 After dyeing 9 Normal reduction washing was carried out, and after drying, it was set at 17°C to remove dyed wrinkles, and then the following second step was carried out.

The second process is the overprinting process, using a roller printing machine, and the engraving opening to the top of the small pattern on the entire surface is a combination of the upper pattern, the width of the line of the pattern is about 0.81N, and the distance between the patterns is also It was set to about 0.8- and was arranged in a staggered manner. As a result of setting the long part of the upper pattern line to about 4M, the print area is about 47mm compared to the ground dyeing.
%. In order to make the hue density of this overprint darker than the gray of the background dyeing, the hue was set to black. The dyeing recipe for the second step is shown below.

10- Overblint prescription The viscosity of the above formulation was 1100 cps.

After drying the print, use a continuous high temperature steamer at 175℃
After fixing the dye for 10 minutes, the dye was then washed with water, hot water, reduction cleaning, etc. using a wince.

The surface of the fabric, which has undergone the second step of drying in a short loop after dehydration, has a fine black pattern overprinted on top of the dyed gray background. When looking at this surface from a distance of 5m, the microscopic burrows are not recognized as upper pedicels and appear almost dotted, and from a distance of 2m, even if they are not brushed, they appear to be almost black and gray with a marbled tone. It was something. Subsequently, the front surface was brushed 10 times and the back surface was brushed 6 times using a hydraulic needle cloth raising machine.

When the number of brushing on the surface was about 6 to 4 times, the overprint pattern was still only slightly broken, and it could not be said to have a marbled look, but the density of the brushing was high (the more it became, the closer it became to a marbled look). As a result, when the ground structure of the 5-ply satin fabric was raised to the extent that it could not be seen due to the raised naps, no upper pattern was recognized, and the fabric that had completed the 5th process was recognized as having a marbled tone.Subsequently, it was set. However, after uniformly applying 3% urethane resin, 2% softener, and 2% antistatic agent, and drying while smoothing with a brush, the fabric was finished with marbled harmonious wool with a three-dimensional effect.Moreover, most of the brushed fluff was removed. is 0.6
Since it was a fluffy material (d), it had an excellent feel and texture. The finish date was approximately 2509//71'.

Example 2 In the same manner as in Example 1, the following second step was carried out on the ground-dyed fabric that had been subjected to the first step. In the second step, a commercially available black speck dye was used as a small pattern on the entire surface, and the printing paste viscosity was adjusted to 5200 cps using a rotary screen method to perform background dye overprinting. After drying, overprinting was performed once again in the same manner as described above. This was done for the purpose of increasing the degree of overlapping specifications, increasing the size of the dots, and preventing smearing. After this, the dye was fixed in the same manner as in Example 1, and the surface was
There are small black dots almost uniformly over the entire surface, and there are about 40 pieces/c4° with a diameter of about 0.8 to 1-1.
Approximately 50 pieces/d of 0.8 cod, 20 pieces/d of about 0.5 m in diameter, 10~10 pieces/d of cod with a diameter of about 0.5 u or less
There are 50 pieces/i, and the area of spec dyeing is about 5
After the second step, which was 096, the fifth step was the same as in Example 1, where the material was raised and finished. The brushed fabric that finished the 6th process was a marbled-textured fabric with a three-dimensional feel. Patent applicant: Yunichika Honshu Shiki Kokoshichi 15-
