JPH05171578A - Production of polyester cloth having particular pattern - Google Patents

Abstract

PURPOSE:To obtain a cloth having particular pattern with partly different glass by carrying out the alkali-treatment of a cloth manufactured from a splittable polyester conjugate fiber composed of a component scarcely soluble in alkali and a component easily soluble in alkali. CONSTITUTION:An alkali-containing printing paste is printed to a cloth manufactured from a splittable polyester conjugate fiber composed of a component scarcely soluble in alkali (e.g. polyethylene terephthalate) and a component easily soluble in alkali (e.g. a polyester copolymerized with 5-sulfoisophthalic acid). The printed cloth is heat-treated to split the single fiber of the alkali- treated part or to form edge-like recesses in the direction of the fiber length. The alkali-treated part causes irregular reflection of light to develop white opaque gloss and, accordingly, the obtained polyester cloth has gloss difference between the alkali-treated part and the non-treated part.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a specially patterned cloth using polyester split fiber-type composite fibers and having a portion having a partially different gloss, which is used for interiors, general clothing and the like. it can.

[0002]

2. Description of the Related Art Conventionally, as a method of manufacturing a patterned cloth partially having a different gloss, there is a method of partially coating the cloth with a white pigment such as titanium oxide or zinc oxide added to the adhesive. The coated fabric has drawbacks such as a hard texture and difficulty in additional processing such as imparting flameproofness.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of such a situation as described above, and does not harden the texture of the fabric, and is easy to post-process such as flameproof treatment and has different gloss. It is intended to obtain a method for producing a special pattern fabric having a portion.

[0004]

The present invention achieves the above object and has the following structure. That is, the present invention is to print a fabric containing a polyester-based split fiber composite fiber composed of an alkali hardly soluble component and an alkali easily soluble component on at least a part of the constituent yarns, and print with an alkali-containing printing paste and heat. The gist of the present invention is a method for producing a polyester-based special pattern fabric, which is characterized by performing neutralization and washing treatment after the treatment.

The present invention will be described in detail below. In the present invention, a polyester-based split fiber type composite fiber composed of an alkali hardly soluble component and an alkali easily soluble component is used for at least a part of the yarn constituting the cloth. The polyester split fiber type composite fiber composed of an alkali hardly soluble component and an alkali easily soluble component is, for example, in a fiber single yarn cross section as shown in FIG.
It is a fiber obtained by arranging a polyester-based polymer which is a component hardly soluble in alkali and a polyester-based polymer which is a component easily dissolved in alkali, and which is subjected to composite spinning and stretching at a weight ratio of 1: 5 to 5: 1. The number of divisions of the polyester split fiber type composite fiber is preferably 4 or more. If it is less than 4 divisions, even if the single yarn is split by alkali treatment, the pattern due to the difference in gloss, which is a feature of the present invention, becomes monotonous.

The alkali hardly soluble component of the polyester split fiber type composite fiber comprising the alkali hardly soluble component and the alkali easily soluble component of the present invention contains a general polyester component terephthalic acid as a main acid component and has 2 to 6 carbon atoms. An alkylene glycol, particularly preferably a polyester component containing ethylene glycol as a main glycol component, or a polyester component containing terephthalic acid as a main acid component and butadiene glycol as a main glycol component.

The alkali easily soluble component is the above polyester, which contains 5-sodium sulfoisophthalic acid as the third component,
Sulfoisophthalic acid, isophthalic acid, adipic acid, P-
Oxybenzoic acid, naphthalene-2,6-dicarboxylic acid,
It is a polyester component obtained by copolymerizing a known copolymerization component such as sebacic acid, 1-4 butanediol, P-B oxyetokin benzoic acid, cyclohexane dicarboxylic acid, neopentyl glycol and the like in several mol% to 20 mol%.

In the present invention, a fabric is prepared by using polyester split fiber type composite fibers for at least a part of the constituent yarns. This fabric may be woven, knitted, non-woven fabric, etc. For example, in the case of woven fabric, polyester-based split fiber composite fibers may be used for all of the warps and wefts, and may be used for part of the warps or wefts. .

A cloth using polyester split fiber type composite fibers is subjected to alkali treatment. Alkali treatment is performed by applying an alkali-containing printing paste to a desired pattern on a fabric using polyester split fiber composite fibers, drying and then heat-treating with dry heat or wet heat to neutralize and wash. It means that the easily soluble alkali component is removed.

As the alkali of the printing paste containing alkali,
It is a hydroxide of an alkali metal such as potassium and sodium. As the paste material used for printing paste, there are paste materials such as starch, rice bran, tokacan gum, sodium alginate, polyvinyl alcohol and polyvinyl acetate.

After the alkali treatment, the single filament of the polyester split fiber type composite fiber dissolves the alkali easily soluble component and splits, or edging-like depressions are formed in the length direction of the fiber. The alkali-treated portion shows a white opaque luster due to diffuse reflection of light as if the transparent ice was shattered into pieces.

[0012] The proportion of the alkali-soluble component that is removed by alkali treatment is preferably 20% or more, more preferably 30% or more. When this ratio is small, production control becomes difficult and the pattern becomes monotonous.

The alkali-treated fabric may be subjected to post-treatment, if necessary. For example, when flameproofness is required, sufficient flameproofing performance can be obtained by adsorbing or coating an ordinary flameproofing agent on the cloth. The present invention has the above configuration.

[0014]

According to the present invention, when a cloth using a polyester-based split fiber composite fiber composed of an alkali hardly soluble component and an alkali easily soluble component is printed with an alkali-containing paste and alkali-treated, the polyester-treated portion of the alkali-treated polyester Split single fibers of split fiber or split fibers or edging-like depressions in the length direction of the fiber, as if the transparent ice was shattered finely, the light diffusely reflected and showed a white opaque luster. A special pattern is created due to the difference in gloss from the untreated part.

[0015]

EXAMPLES Examples of the present invention will be described below. Fibers obtained by composite spinning and stretching at a weight ratio of 1: 1 using a polymer in which 2.5 mol% of 5-sulfoisophthalic acid is copolymerized with polyethylene terephthalate as an alkali easily soluble component and polyethylene terephthalate as an alkali hardly soluble component are shown in FIG. Polyester split-type composite fiber with single fiber cross section
A plain woven fabric having a warp density of 95 yarns / inch and a weft density of 95 yarns / inch was woven by using yarns twisted in a S direction of 500 T / m in 100 denier / 24 filament for warp and weft. This greige machine was heat set at 180 ° C, scoured with anionic surfactant, dried, printed with the following special printing paste, steamed for 15 minutes after hot air drying, and sizing while rubbing the fabric in a hot water bath. Was removed, washed in a PH4.5 bath containing acetic acid, washed with water, dried and subjected to finishing heat setting to obtain a special patterned fabric of the present invention.

The alkali-dissolvable component of the fiber single yarn of the printed portion of the obtained fabric is dissolved to form a depression in the length direction of the single yarn, showing a bright white luster due to irregular reflection of light and printing. Due to the difference in gloss from the non-existent part, it had a special pattern and had a soft texture.

[0018]

[Effect] As described above, according to the present invention, due to the characteristics of the yarn used, the fabric in which the alkali-dissolvable component in the portion printed with the alkali-containing printing paste is melt-processed has a hue which has never been obtained.
A fabric with a special pattern exhibiting gloss can be obtained, and there is no defect that the texture becomes hard, and for those requiring flameproofness, sufficient flameproofness can be obtained by ordinary flameproofing.
