JPH02154059A - Method for making wash-out like wrinkles on cloth - Google Patents

Abstract

PURPOSE:To obtain cloth for casual purposes, having good hand or touch with fine and uniform wrinkles and worn-out appearance by treating ropes of synthetic fiber cloth with hot water at a specific temperature, coating the cloth with a solution containing a pigment on one surface, and crumpling the cloth soft. CONSTITUTION:The cloth of synthetic fibers is made rope-like and treated with hot water at 80 to 140 deg.C. Then, the cloth is coated with a resin solution containing pigments on one surface, dried, heat-treated to fix the pigments. The cloth is sewed and crumpled soft in a rotary washer or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wash-out wrinkle treatment for fabrics that can impart fine and uniform wrinkles and a washed-out feel.

(Prior art and its problems) Conventionally, various developments have been made regarding wrinkled fabrics, and many have been on the market. However, most of these are simply wrinkles added to the final product using a wince, jet dyeing machine, rotary washer, etc., or
6-5867, Japanese Patent Publication No. 59-39648, etc., the wrinkles are simply added using a special wrinkle processing machine, or the wrinkles are only added by embossing or the like. There was a problem in that the unevenness was large and the difference between products was large, making it impossible to obtain fine and uniform wrinkles with high firmness.

Therefore, for synthetic fiber fabrics, use highly twisted yarns for the warp and/or weft! i! A method has been used to create wrinkles by making use of the shrinkage of the highly twisted yarn after weaving.
There has been a problem in that grain spots occur when creating grains with a washer or the like.

In view of the above-mentioned circumstances, the inventors of the present invention have conducted repeated studies with the aim of imparting fine and uniform wrinkles to synthetic fiber fabrics, and as a result, they have developed a method of hot water treatment at 90 to 140°C in the form of ropes. It has been found that it is suitable to perform a rubbing treatment after that.

The present invention was made based on the above-mentioned knowledge, and provides a fabric that can satisfy the effects of fine and uniform wrinkles and a washed-out feeling without impairing the texture and strength of the synthetic fiber fabric itself. The purpose of the washout wrinkle processing is to provide a processing method.

(Means for solving the problem) The above purpose is to attach 9 ropes to a fabric made of synthetic fibers.
The washout creasing of the fabric is achieved by a processing method characterized by subjecting it to a hot water treatment at 0 to 140° C., followed by coating with a pigment-containing solution and subsequent manipulation.

Furthermore, the method of the present invention will be described in detail.The fabric made of synthetic fibers referred to in the method of the present invention includes woven fabrics and articles made of nylon, polyester, acrylic, etc. alone or blended or interwoven with these fibers. The counts and densities of the warp and weft yarns constituting the structure are not particularly limited as long as wrinkling and fabrication do not occur during processing. The synthetic I&fiber fabric is then desizing, scouring, and
Preprocessing such as presetting is performed.

What is important in the hot water treatment process to achieve the method of the present invention is to maintain the state in an expandable and contractible state.Under these conditions, a liquid jet dyeing Ch1 car scouring machine is suitable, especially with low tension and a massaging effect. A jet dyer is preferred. The treatment temperature is preferably 90 to 140°C in order to develop the stretching effect; below 90°C, wrinkles are less likely to occur;
The above is difficult to implement with normal equipment due to the high pressure. Further, the treatment time may normally be 20 to 60 minutes.

In the method of the present invention, the method of coating with a solution containing a pigment may be either dry coating or wet coating, and coating methods such as a floating knife coater, a knife over roll coater, a reverse roll coater, a roll doctor coater, etc. can be used. However, when using a doctor's knife, the fabric is squeezed with the doctor's knife, which stretches the wrinkles, so there is no need to increase the width of the fabric afterwards. It is necessary to release it. Of course, after coating, it is necessary to fix the pigment to the fiber to some extent by a gentle heat treatment at about 140°C. In addition to coating, it is of course possible to perform various treatments such as pumping and softening.

However, water repellent treatment can be performed either before or after coating, but if it is performed before coating, it is necessary to pay sufficient attention to adhesive strength.

In the method of the present invention, a wince, a rotary washer, and a liquid jet dyeing machine are used as devices for imparting wrinkles and a washed-out feeling by rubbing the cloth, but a rotary washer is used to obtain finer wrinkles.

The processing conditions for the rotary washer are a rotation speed of 3 to 40 revolutions/minute and a bath ratio of 1:5 to 1:40. Set temperature 40-1
Preferably, the temperature is 30°C and the setting time is in the range of 5 to 120 minutes.
Rotation speed 10-20 rotations/min, bath ratio 1:20-+:go,
More preferably, the set temperature is 50 to 90°C and the set time is 20 to 60 minutes.

If the treatment conditions are outside the above range, wrinkles may become uneven or defects such as pilling may occur on the surface of the fabric.

This rubbing process can be done before or after sewing, but
It is preferable to do it after sewing to create a natural wrinkled feel at the seams. Of course, in the case of sewing after sewing, only a rotary washer can be used among the above-mentioned devices.

(Example) Next, the method of the present invention will be specifically explained with reference to Examples.

Example 1 Both warp and weft are 50 denier 72 filament twin yarns,
Polyester taffeta having a warp density of 121 yarns/inch and a weft yarn density of 88 yarns/inch was subjected to a scouring preset treatment. Next, the bath ratio was 1 using a Loco jet dyeing machine manufactured by Hokuriku Kako A.
: Hot water treatment was carried out at 135° C. for 60 minutes at 15°C. Next, acrylic ester resin perchlorethylene solution (solid content) 1
A pigment solution prepared by mixing 5 parts of pigment per 00 parts of pigment was applied to one side of the fabric using a knife-over roll coater, and immediately dried (120°C) and heat-treated (140°C).

Next, the fabric after the heat treatment was sewn, placed in a rotary washer, and subjected to a kneading process. The processing conditions for the rotary washer are 15 rotations/min, bath ratio 1:20, and temperature 90.
The temperature was 30 minutes.

After the treatment with a rotary washer, the fabric was centrifugally dehydrated and tumble-dried at a temperature of 90° C. for 50 minutes to obtain a product of an example according to the method of the present invention.

Comparative Example 1 Using the same polyester taffeta as in Example 1, the same process as in Example 1 was carried out except for the part that was treated with hot water using a loco-type jet dyeing machine during the process of Example 1 to produce a product of comparative example. I got it.

The wrinkles of the product produced by the method of the present invention were fine and uniform;
The conventional product of Comparative Example had uneven wrinkles.

(Effects of the Invention) As described above, according to the method of the present invention, fine and uniform wrinkles and a washed-out feel can be obtained on the fabric, and such fabric has a good texture and thickness, making it suitable for casual use. Very useful.
