[0007]

[0008] In the polyester fiber cloth of the present invention, the cloth is a cloth such as a woven fabric, a knitted fabric, or a nonwoven fabric in which the polyester fiber is contained as a part or all of the fibers constituting the cloth. It has a handle portion formed with fibrillated fluff having a diameter of 0.05 to 5 μm and a length of 5 μm or more, protruding from the fiber surface of the polyester fiber having the constitution.

If the fibrilized fluff protruding from the polyester fiber has a diameter of more than 5 μm or a length of less than 5 μm, the texture of the fabric is insufficiently improved,
Satisfactory flexibility, dry feeling and slimy feeling cannot be obtained.
The handle portion on which the fibrillated fluff is formed may be present on the entire surface or a part of the fabric.

In the present invention, the base polymer of the polyester fiber constituting the fabric comprises ethylene terephthalate as a main repeating unit, terephthalic acid or its ester-forming derivative as a dicarboxylic acid component, and ethylene glycol or its ester-forming derivative. A polyester polymer having a diol component as a diol component is a typical example, but a polyester polymer in which a part of a dicarboxylic acid component is replaced with another dicarboxylic acid and a portion of a diol component is replaced with another diol is also used. Good.

The method for producing the polyester fiber fabric of the present invention will be described below. In the method of the present invention, the polyester-based fibers used in the construction of the fabric include the organic sulfonic acid metal salt represented by the above general formula in an amount of 0.1 to 8% by weight.
Or a mixture of a metal salt of an organic sulfonic acid and polyethylene having an average molecular weight of 10,000 or less.
It must be a polyester fiber comprising a polyester polymer containing from 10 to 10% by weight.

[0012] The metal organic sulfonic acid salt contained in the polyester fiber, when the fabric is subjected to alkali weight reduction treatment,
It becomes an active site in alkaline hydrolysis and is an essential component for forming a large number of fibrillated fluffs on the fiber surface of the polyester fiber. If the content of the organic metal sulfonate is less than 0.1% by weight, fibril The formation of fluff that has become insufficient becomes insufficient, and the purpose of improving texture is not achieved.
If the content is more than wt%, the process passage stability is deteriorated. The preferable content of the organic sulfonic acid metal salt is 0.5 to 5
% By weight.

Further, the mixture of the metal salt of organic sulfonic acid and polyethylene contained in the polyester fiber can form a large number of fibrillated fluffs on the fiber surface due to the coexistence of polyethylene when the fabric is subjected to alkali weight reduction treatment. When the content is less than 0.1% by weight, the formation of fibrillated fluff becomes insufficient, and the object of improving the texture is not achieved.
The process stability is deteriorated. The preferable content of the mixture of the metal salt of organic sulfonic acid and polyethylene is 0.1%.
5 to 7% by weight.

In the method of the present invention, the metal salts of organic sulfonic acids represented by the above general formula which are contained alone or as a mixture in the polyester fiber include, for example, butylsulfonic acid, hexylsulfonic acid, octylsulfonic acid,
Alkali metal salts of aliphatic sulfonic acids such as decylsulfonic acid, laurylsulfonic acid, myristylsulfonic acid, palmitylsulfonic acid, and stearylsulfonic acid, and alkali metal salts of aromatic sulfonic acids such as toluenesulfonic acid and dodecylbenzenesulfonic acid. No. Such an organic metal sulfonic acid salt does not need to be a single compound, and may be a mixture of various organic sulfonic acid metal salts. As a preferred specific example, a mixture of an alkylsulfonic acid sodium salt having 12 to 17 carbon atoms Is mentioned.

The polyethylene mixed with the metal organic sulfonic acid salt contained in the polyester fiber has an average molecular weight of 10,000 or less, preferably, in order to reduce the high melt viscosity of the metal organic sulfonic acid salt. 5,
000 or less low-viscosity polyethylene is used. The mixing ratio (weight ratio) in the mixture of the organic sulfonic acid metal salt and polyethylene is preferably metal organic sulfonic acid salt: polyethylene = 5: 95 to 95: 5.

The metal salt of an organic sulfonic acid or a mixture of a metal salt of an organic sulfonic acid and polyethylene is contained in a polyester fiber by adding it in a process of producing the polyester polymer before forming the fiber or in a spinning step. . The method for producing the fiber is not particularly limited.

Using a polyester fiber containing such an organic sulfonic acid metal salt or a mixture of an organic sulfonic acid metal salt and polyethylene, a fabric having the polyester fiber as a constituent fiber is formed by weaving, knitting or the like.

In obtaining a polyester fiber fabric by the method of the present invention, a sizing agent containing a polyhydric alcohol ethylene oxide adduct is printed in the form of a fabric formed by weaving, knitting or the like at a pattern of 100 ° C. or higher. It is essential to heat-treat at a temperature of

The polyhydric alcohol ethylene oxide adduct used in the method of the present invention includes ethylene glycol, propylene glycol, hydrobenzoin, benzopinacol, cyclopentane-1,2-diol, cyclohexane-
It is produced by adding 2 mol or more of ethylene oxide to a polyhydric alcohol such as a dihydric alcohol such as 1,4-diol and a trihydric alcohol such as glycerin. The method of the addition reaction is not particularly limited and is known. It is good by the method of. As the polyhydric alcohol ethylene oxide adduct preferably used, ethylene glycol 5 to 30 ethylene oxide adduct, glycerin ethylene oxide 3
To 28 adducts.

The polyhydric alcohol ethylene oxide adduct is added and contained in an amount of 1 to 50 g, preferably 5 to 20 g per 100 g of the sizing agent, though it varies depending on the type, constitution ratio and the like of the polyester fiber constituting the fabric. As the sizing agent, known, natural, processed, semi-processed, or synthetic sizing agents such as wheat starch, tragacanth gum, locust bean gum, carboxymethyl cellulose, polyvinyl alcohol, and sodium polyacrylate are used alone or in combination of two or more. In addition, when a dye is added to the paste, coloring can be performed at the same time. In such a case, it is necessary to use a dye that can withstand the subsequent alkali weight reduction treatment.

The printing of the paste on the fabric is performed by any known method, and printing is performed in an arbitrary pattern from partial printing to printing of almost the entire surface. After printing and drying, heat treatment is performed at a temperature of 100 ° C. or higher.
30 seconds or more at 0 to 220 ° C, more preferably 170 to 2
60 ° C. or more at 00 ° C., and in a high-pressure moist heat atmosphere, at a temperature of 100 to 150 ° C. for 10 minutes or more, more preferably 110 ° C.
In the case of a dry atmosphere at a temperature of 130 ° C. or more for 20 minutes or more and a relative humidity of less than 90%, the temperature is 150 ° C. or more for 30 seconds or more, and more preferably 170 ° C. or more for 60 seconds or more.

By this heat treatment, the polyhydric alcohol ethylene oxide adduct in the printed portion permeates into the polyester fiber, and when the fabric is subjected to alkali weight reduction treatment, the organic sulfonate metal salt or organic sulfone contained in the fiber is removed. It is reduced in weight from the existing portion of the mixture of the acid metal salt and the polyethylene, and further promotes the formation of fibrillated fluff on the fiber surface, and acts as a weight loss promoter.

Next, it is necessary to subject the heat-treated fabric to an alkali weight reduction treatment with an aqueous solution of an alkaline compound. The weight loss rate is preferably 5% by weight or more, more preferably 15% by weight or more of the polyester fiber of the fabric constitution. By this alkali weight reduction treatment,
The weight loss accompanying the elution of the metal sulfonic acid salt or the mixture of the metal sulfonic acid salt and polyethylene easily occurs, and fibrils having a diameter of 0.05 to 5 μm and a length of 5 μm or more are formed on the surface of the polyester fiber in the printing portion. A fluff is formed, and a handle having fibril fluff on the fabric surface is obtained.

In the alkali weight reduction treatment, alkali metal hydroxides such as sodium hydroxide and potassium hydroxide and alkaline earth metal hydroxides such as calcium hydroxide and magnesium hydroxide are used as alkaline compounds. And an amine such as triethanolamine, diethanolamine, monoethanolamine or the like is used in combination in an aqueous alkaline compound solution.

As the alkali reduction treatment method, any known method generally applied to polyester-based fabrics as a weight reduction process is applied.
It can be appropriately changed according to the fineness of the polyester fiber constituting the fabric, the amount of the inclusions, the composition ratio, and the like. As a processing method, it is preferable to apply a method in which a kneading action is added by contact between fabrics or between a fabric and a processing device wall during processing,
A liquid flow method using a liquid flow dyeing device or the like is suitable.

In the present invention and the method of the present invention, the fabric may be constituted by using only the polyester-based fibers. However, for the purpose of maintaining the strength of the fabric, other fibers which are not reduced or are hardly reduced are mixed. When other fibers are mixed, it is necessary that the range be such that the texture of the fabric obtained by the method of the present invention is not impaired.

The polyester fiber fabric of the present invention is naturally subjected to a dyeing or printing process after the alkali weight reduction treatment in the production thereof, so that the handle of the fibrillated fluff and the whole or partial coloring can be obtained. A variety of advanced design effects can be provided by the combination.
