Abstract

PURPOSE:To obtain cloth having a vivid pattern and capable of largely changing shade of color of the pattern by an angle observed and simultaneously containing a polyester fiber having soft handle and high color fastness. CONSTITUTION:A printing sizing material containing a carrier capable of swelling a polyester and a water soluble resin is printed onto cloth containing a polyester fiber and then the cloth is heat-treated to nap the cloth and the cloth is washed to remove the water soluble resin and then the polyester fiber is dyed to produce the objective napped cloth having the printed part dyed into deep color and reduced in napping and having vivid pattern.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a napped cloth having a clear pattern.

[0002]

2. Description of the Related Art Conventionally, a water-insoluble resin is printed and dyed before or after the step of raising the surface of a cloth to produce a napped cloth having a pattern due to the deep dyeing effect of the resin. However, in the conventional method, the resin remains on the cloth, the texture is hardened, or the dye fastened to the resin portion causes a decrease in dyeing fastness, and further, the pattern becomes unclear due to the hue. ..

Japanese Patent Publication No. 54-38240 discloses a paste paste comprising a sizing agent which can be removed by washing with water on a woven or knitted fabric mainly composed of synthetic fibers, and a swelling agent for the synthetic fibers. Is printed in a pattern and then heat-treated to make the printed part of the woven or knitted fabric a dense structure with a swelling agent, and then napped to prevent napping of the printed part, and further to wash the paste paste by washing with water or the like. Disclosed is a method for producing a patterned brushed fabric, which is characterized by being removed. However, this method has a drawback of lacking the sharpness of the pattern because the pattern is imparted only by suppressing the raising of the fabric by the dense structure of the fabric by the swelling agent.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and produces a napped fabric having a sharp pattern and a soft texture and high dyeing fastness. It provides a way to do it.

Means for Solving the Problems That is, according to the present invention, a printing paste containing a carrier for swelling a polyester and a water-soluble resin is printed in a pattern on a fabric containing polyester fibers, then heat-treated, and then raised. Thereafter, the cloth is washed to remove the water-soluble resin, and then the polyester fiber is dyed, and the above-mentioned printed portion is dyed in a dark color and has a sharp pattern pattern with less napped cloth. The manufacturing method of

The carrier itself for swelling the polyester used in the present invention is known, and examples thereof include phenylphenols, chlorobenzenes, naphthalenes, diphenyls, phenol, cresol, benzyl alcohol,
Examples thereof include phenylethyl alcohol and tolyl alcohol. The concentration of the carrier in the printing paste is usually 1 to 3
It is 0% by weight, preferably 5 to 15% by weight.

As the water-soluble resin, water-soluble synthetic resins such as polyvinyl alcohol, polyvinylpyrrolidone, polyacrylic acid ester and the like are used. The concentration of these resins in the printing paste is usually 1
It is 0 to 60% by weight, preferably 20 to 40% by weight.

The amount of the carrier and the water-soluble resin applied to the cloth is preferably 0.5 to 20% by weight, particularly preferably 2 to 10% by weight, based on the weight of the cloth in the pattern portion.

The cloth containing the polyester fiber of the present invention is a woven or knitted fabric having a content ratio of the polyester fiber of 20% by weight or more, and preferably the content ratio thereof is 50% by weight.
That is all. Examples of the polyester fibers include polyethylene terephthalate, polytetramethylene terephthalate, polyethyleneoxybenzoate, poly 1,4-dimethylcyclohexane terephthalate, polypivalolactone, and copolyesters containing these as components. The fibers other than polyester are not particularly limited, and polyamide, acrylic, cotton, etc. are used.

In the present invention, a printing paste composed of such a carrier for swelling polyester and a water-soluble resin can be printed on the surface of the fabric in a pattern to obtain a desired pattern.

The subsequent heat treatment may be carried out under dry heat or wet heat, and is preferably carried out at 100 to 180 ° C. for 2 to 15 minutes. By the heat treatment, the carrier can be diffused into the polyester molecule, and the polyester fiber in the printed portion swells by the action of the carrier.

The raising is preferably carried out by using a sanding raising machine, but a needle cloth raising machine or the like may be used. In the present invention, the pattern-like printed portion is suppressed from napping because the water-soluble resin forms a film on the surface of the cloth.

Next, the cloth is washed to remove the water-soluble resin. In the present invention, since the resin is water-soluble, the resin can be completely completely removed only by washing with water.

For dyeing polyester, a disperse dye is usually used as a dye, and as a dyeing method, a batch dyeing method such as a jet dyeing machine, a Wins dyeing machine and a jigger, or a continuous dyeing method such as a thermosol method may be used. ..

As described above, according to the method of the present invention, the printed portion is not raised, so that a pattern is formed between the raised portion and the non-raised portion. Further, the pattern portion is dyed dark due to the action of the carrier in dyeing. Therefore, a very clear pattern pattern can be obtained even on a fabric having long naps. Further, since the naps are partially present, it is possible to obtain a characteristic that the shade of the pattern pattern greatly changes depending on the viewing angle. In addition, since the water-soluble resin is used, there is no residual resin, so the texture is soft,
In addition, it is possible to manufacture a napped fabric having high dyeing fastness.

Hereinafter, the present invention will be described in more detail by way of examples, but the present invention is not limited to these examples.

Subsequently, heat setting was carried out at 190 ° C. for 1 minute.

10% by weight of phenylphenol as a carrier for swelling polyester on the cloth and 20% of polyvinyl alcohol (PVA217) as a water-soluble resin.
Printed in a pattern with a printing paste containing 10% by weight. The applied amounts of the carrier and the water-soluble resin were 5% by weight and 10% by weight, respectively, based on the weight of the fabric in the pattern portion. next,
Heat treatment was carried out at 180 ° C. for 10 minutes in the presence of steam. Then, the fabric surface was raised by a sanding raising machine.

Next, the napped fabric is kept at 20 ° C. for 3 hours.
After washing with water for 0 minutes to remove the water-soluble resin, a jet wins dyeing machine was used and the following dyeing recipe was used to obtain a temperature of 130.
Dyeing was carried out at 60 ° C. (pressure 2.8 kg / cm ² ) at a bath ratio of 1:10 for 60 minutes.
