Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for wrinkling a raised fabric made of polyester fibers.

Conventionally, the method of wrinkling fabric is to use strongly twisted yarns for the warp, weft, warp, and weft, and to make use of the shrinkage of the twisted yarns after weaving to perform a wet treatment called shibo-etaki to create wrinkles on the surface of a 1wk item. There is a mechanical method in which the fabric is passed between two rolls with unevenness in a linear or other shape and pressed strongly from above and below to form the pattern.

However, with these conventional wrinkle processing methods, the degree of wrinkles is very fine, the unevenness of the wrinkles is low, and it is not possible to obtain a fashionable and high-quality cough that is acceptable to today's young people. The problem was that there was no

In order to solve these problems, the inventors of the present invention conducted extensive research and found that a fabric made of polyester fibers with limited thickness, electrolytic corrosion, and moisture content was twisted a limited number of times, and in this state was subjected to high-pressure steaming. As a result, it has durable, moderately sized wrinkles with high unevenness, and the wrinkles on the surface of the fabric have good uniformity, and by using a raised fabric as the fabric, changes in the fluff at the wrinkles are added, creating a fashionable look. The present invention was achieved by discovering the fact that high quality wrinkles can be obtained.

That is, 1. The present invention is a rope that is twisted 5 to 20 times per 1 meter length to a raised fabric made of polyester yarn fibers having a thickness of 0.2 to 1 fi, 100 to 300 g per weight, and a moisture content of 1096 or less. The gist of the patented wrinkling processing method is to perform a high-pressure steaming treatment at 120 to 140° C. in width.

Two aspects of the present invention will be described in detail below.

The raised fabric made of polyester fiber used in the present invention refers to one-sided or double-sided knitted fabric such as woven fabric, knitted fabric, nonwoven fabric, etc.
It is a fabric that is raised using side rolls, sand belts, etc. Here, polyester fibers are especially selected because of their heat resistance when made into fabrics. ! ! This is because it has excellent setting properties, strength, texture, color fastness, etc.

The thickness of the raised fabric is 1W or less, and the weight is 100 to 3 per 1 d.
The reason why it is set at 00g is that this range is the condition under which the wrinkles of the present invention can be obtained most stably. That is, the thickness is 1fi
If the thickness is less than 1U, the fold angle of the fabric will be acute when wrinkled, and the wrinkles will be beautiful and have excellent durability, but if the thickness is 1U or more, the wrinkled fabric will be folded at an acute angle. The fold angle is obtuse, and when wrinkled, the angle of the wrinkles afterward becomes rounded, making it unattractive and inferior in durability. In the present invention, as mentioned above, the thickness only needs to be 1 fi or less, but in order to obtain even better quality, the thickness of the fabric is 0.4 to 0.8 f.
l is the most suitable. In addition, when Q is less than 4 mg, even raised fabrics made of polyester fibers do not have a tear strength that is practical for clothing.

In addition, the weight of the fabric is 100 to 600 g per 1771'
Like the thickness, this is the condition for the raised fabric that provides the most stable wrinkles according to the present invention. Namely.

There is a relationship between the weight per piece and the thickness, and when the thickness of a raised fabric is 1 fl or less and is 100 to 300 Q, the width of the raised fabric is usually about 901 to 150 cm. In addition, for clothing applications, the weight per 1 d of raised fabric is 10
0-300g is the most suitable weight.

In terms of strength, it is a weight that provides practical strength. However, the important thing is that when performing the wrinkle processing of the present invention,
If the weight per 1 d is less than 100 g, it is easy to wrinkle and a durable fabric can be obtained, but the actual situation is that the fabric lacks practical strength as a raised fabric. In addition, when the weight per y/y exceeds 500g, it is also related to the thickness, and with wrinkles as mentioned above, the folding angle of the fabric becomes obtuse, and with 1wI, the angle of the image afterward becomes rounded and not beautiful. Only products with inferior durability can be obtained.

The raised fabric used in the present invention has a thickness of 0.2 to 11+1. It is made of polyester fibers of 100-101 F/d of weight, and one more important thing is that the moisture content of the fabric is 10% or less. The moisture content of 10% here means that when the weight in a normal dry state is 200g per in/in, the weight when water is uniformly applied is 220g per 1d.
In the following, it means close to the so-called almost dry state. This is because if the moisture content is 10% or more, a distributed bed of moisture content will occur during the next high-pressure steaming treatment in the rope state, resulting in wrinkles and spots on the dyed fabric.

In the present invention, high-pressure steaming at 120 to 140° C. is performed on the above-mentioned raised t rope, which is twisted 5 to 20 times per meter of length. Regarding rope-like twists, if the number of twists is less than 5 times per 1 m of length, the shape of the warmer is only in the length direction, resulting in wrinkles that are too large for clothing, which is undesirable, and 20 times per 1 m of length. If such twisting is applied, the effects of the subsequent high-pressure steaming treatment will not reach the inside of the rope, resulting in defects such as uneven treatment and an unnecessarily long treatment time. Furthermore, if the thickness of the fabric is close to 1111 and the weight of 1 is close to 5009/ld, then 1
This is because applying twists of 20 times or more per m is mechanically impossible, creating a condition that may cause damage to the fabric.

The high-pressure steaming treatment of the rope-like fabric may be carried out by wrapping it around a perforated drum made of aluminum or wood.

Alternatively, the method may be carried out by cramming several cases. However, at this time, it is necessary to wrap or spread an undercloth to prevent the rope-like fabric from coming into direct contact with the drum or case and causing partial gloss spots. Furthermore, it is necessary to take similar measures to the upper part to prevent defects such as partial drying during setting or partial lidding caused by drain. As the high-pressure steam treatment device, a device equipped with a vacuum device and capable of saturated steam treatment is desirable, and a set of processed yarns generally made of synthetic fibers or a Nuchi Gosana Tsuta used for color development in textile printing may be used. A good treatment temperature is 120 to 140°C (120 to 140°C).
Below 140°C, acid fixation is insufficient and durability is poor;
If the temperature is higher than 0.degree. C., the dye may begin to migrate, and the high pressure may cause strain on the equipment, making it uneconomical. Processing time is usually 30~
60 minutes is fine.

As mentioned above, in the present invention, a raised fabric made of polyester fibers having a thickness of 0.2 to 1 M, a weight of 100 to 300 g per meter, and a moisture content of 10% or less is twisted 5 to 20 times per 1 meter in length. Seeding of a fabric is a processing method characterized by subjecting it to high-pressure steaming at 120 to 140°C in the form of a rope.1 The wrinkled raised fabric of the present invention is banded in the warp direction as a whole. , the distance between the width of warm and wrinkles is 5-1
Most are around 5W, and the length is 10cN-60CM
There are many types of degree. Untwist after high-pressure steaming treatment,
Fabrics that are stretched under suitable conditions to prevent wrinkles from disappearing and then finished with a finishing agent such as a softener or antistatic agent have durable, moderately sized wrinkles and high unevenness, and the entire surface of the fabric is smoothed. The uniformity of the wrinkles when viewed from the outside is good, and there are also changes in the wrinkles in the areas where the hair is raised, and it is of high quality.

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

Example 1 A polyester false twisted yarn 75d/36f (filament fineness approximately 2d) with an S twist of 500 Wm was used for the warp, and an e-twisted polyester filament yarn 55d/166f (filament fineness approximately 0.5) was used for the warp. d
) A 5-ply sateen fabric for both lines was woven using backboard twisted yarn with S twist ends falsely twisted at 280@/m. The width immediately after weaving is 17
50g, warp density 110 g, weft density 178.

The weight per No. 11 was 87 g. After the usual relaxing, scouring, and dyeing, this was set in a pin tenter at 170° C. for 60 seconds, and then the front side was raised 10 times and the back side was raised 4 times using a needle cloth raising machine. This raised fabric had a width of 115 al, a thickness of about 0.7 fl, and a weight of 149 g per 1 m. Next, water was applied uniformly, squeezed with a mangle, and semi-dried with a roller dryer. The weight per 177 after drying is 158g, and the moisture content is approximately 6%.
Met. Next, 7- Tie one end of the napped fabric to an aluminum case fixed on a rotating table and having one or more holes around the circumference, and rotate the rotating table once to twist it 16 to 18 times per 1 m of length. It was kept in a rope state and stored in the aluminum case mentioned above. Other fabrics were layered around the inside of the aluminum case to prevent scratch-like defects from appearing on the treated fabric. Furthermore, another fabric was placed over the top of the aluminum case to prevent defects from occurring due to drainage.

Next, remove the aluminum case from the turntable and place it in a steam setter manufactured by Toda Seisakusho, and first apply vacuum operation to
After vacuuming to 0 txflg, saturated steam was introduced and high-pressure steaming was performed at 152° C. for 50 minutes. After processing, take it out from the steam setter, pour water over it and cool it down to fix the wrinkles well, then place it on the rotating table mentioned above to fix it.
The fabric was untwisted and taken out while rotating in the opposite direction, dehydrated and spread, and then dried in a short μm dryer.A softener and an antistatic agent were evenly applied, and the fabric was lightly spread to dry.

The obtained raised fabric of the present invention has 8-puff wrinkles all over the length in the length direction, and the distance between the wrinkles is 5.
Most of them are about 151m from the sun, and the length is 15m.
It contained a large amount of copper that intersects at position 401 from cII.

This was a wrinkled fabric that could withstand three wet washes and five dry cleanings. In addition, the unevenness of the wrinkles is moderately high at 0.5 to 3 degrees, and the uniformity of the wrinkles from the entire surface of the fabric is good.
There were wrinkles in the raised part, and it was of high quality.
