DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polyester fiber cloth having at least fluff due to fibrillation on the surface of the cloth and a method for producing the same.

[0002]

2. Description of the Related Art As a processing technique of a polyester fiber cloth, various techniques are known and have been put into practical use.
For example, by processing technology to obtain silk-like fabric,
In terms of drapability, resilience, etc., a material similar to silk cloth is obtained. However, there has not yet been obtained what is satisfactory in terms of dryness, opacity and the like.

Attempts have been made to improve the problem of dryness, opacity, etc., by changing the cross section of the fiber and increasing the fineness of the fiber. There is also a method in which the fiber contains a large amount of titanium oxide or the like, but there are drawbacks such as abrasion of metal and damage to machinery.

[0004] On the other hand, in the etching process of a polyester fiber cloth, an amine, an alkali metal hydroxide,
There is known a method in which an inorganic acid or an organic acid or the like is printed and adhered as a disinfectant, followed by heat treatment to embrittle the modified polyester fiber and remove the corrosion to form a watermark pattern.

[0005] However, the use of amines has environmental problems due to the generation of offensive odors and smoke during heat treatment, and the use of alkali metal hydroxides has the danger of embrittlement of even the unmodified polyester fibers which should be left. However, there is a problem in that the strength of the fabric is reduced, and the use of an inorganic acid or an organic acid has a problem that an odor or smoke is generated at the time of heat treatment, a watermark pattern is monotonous, and lacks sharpness at the time of molding. In addition, when dyeing unmodified polyester fibers in the printed area by adding a dye to the discharge paste, the dye changes color when the discharge agent is an amine, alkali metal hydroxide, inorganic acid or organic acid, and the color is satisfactory. There is a problem that can not be obtained.

Such metal salts of organic sulfonic acids need not be a single compound,
It may be a mixture of various organic sulfonic acid metal salts, and a preferred specific example is a mixture of alkyl sulfonic acid sodium salts having 12 to 17 carbon atoms.

The polyethylene mixed with the metal organic sulfonic acid salt contained in the polyester fiber (A ₂ ) has an average molecular weight of 10,000 or less in order to reduce the high melt viscosity of the metal organic sulfonic acid salt. And preferably 5,000 or less low-viscosity polyethylene. The mixing ratio (weight ratio) in the mixture of the organic sulfonic acid metal salt and polyethylene is preferably the organic sulfonic acid metal 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 fiber shaping or in a spinning step. The method for producing the fiber is not particularly limited.

The polyester fiber (A ₁ ) or (A ₂ ) is used as a constituent fiber, or a mixture of the polyester fiber (A ₁ ) or (A ₂ ) and an organic sulfonic acid metal salt or an organic sulfonic acid metal salt and polyethylene. Polyester fiber not containing is mixed as a constituent fiber by blending, blending, twisting, weaving, weaving or the like, and the fabric is made by weaving, weaving or the like. In addition, polyester fiber (A ₁ )
Alternatively, the mixing ratio of (A ₂ ) and the organic sulfonic acid metal salt or the polyester fiber containing no mixture of the organic sulfonic acid metal salt and polyethylene may be arbitrary.

The polyester fiber fabric of the present invention is manufactured by the following steps (a) to (c). First, in the first step (a), polyester fibers (A ₁₎ or constructed fabric or polyester fiber (A ₂₎ (A ₁₎ or (A ₂₎ and the organic sulfonic acid metal salt or an organic sulfonic acid metal salts A weight loss accelerating paste containing a polyhydric alcohol ethylene oxide adduct as a weight loss accelerator is printed in a pattern on a cloth composed of polyester fibers not containing a mixture with polyethylene.

The polyhydric alcohol ethylene oxide adduct to be contained in the weight loss promoting paste is a product obtained by adding 2 mol or more of ethylene oxide to a polyhydric alcohol. Examples of the polyhydric alcohol include ethylene glycol, propylene glycol, hydrobenzoin and benzopinacol. And dihydric alcohols such as cyclopentane-1,2-diol and cyclohexane-1,4-diol, and trihydric alcohols such as glycerin.

The method of adding ethylene oxide to the polyhydric alcohol is not particularly limited, and a known method can be used. The polyhydric alcohol ethylene oxide adduct preferably used in the method of the present invention includes ethylene glycol 5 to 30 mol adduct of ethylene glycol and glycerin 3 to 28 mol adduct of ethylene oxide. The polyhydric alcohol ethylene oxide adduct varies depending on the type, composition ratio and the like of the polyester fiber constituting the fabric, but is added and contained in an amount of 1 to 50 g, preferably 5 to 20 g per 100 g of the weight loss promoting paste.

Known sizing agents can be used as the sizing agent for the weight loss promoting paste, and include natural, processed, semi-synthetic, and synthetic materials such as wheat starch, tragacanth gum, locust bean gum, carboxymethyl cellulose, polyvinyl alcohol, and sodium polyacrylate. A sizing agent is used alone or in combination of two or more.

In the present invention, a disperse dye may be contained in the paste for accelerating weight reduction. When a paste for accelerating weight loss containing a polyhydric alcohol ethylene oxide adduct and a disperse dye is used as the paste for accelerating weight loss, At the same time, the printing portion can be colored. As the disperse dye to be contained, any disperse dye can be used as long as it is a non-decomposable disperse dye that can withstand alkali treatment in a subsequent step, and particularly preferably a quinone-based or quinophthalone-based disperse dye is used.

The printing of the cloth for promoting weight loss is performed on the cloth by any known method, and the printing is performed arbitrarily from a pattern-shaped partial printing to a substantially entire printing. Alternatively, the weight loss promoting paste and the weight loss promoting color paste may be used for printing in any order.

After printing and drying, the fabric is heat-treated at a temperature of 100 ° C. or more in the next step (b). As preferable heat treatment conditions, in the case of normal pressure and humidity heat of 90% or more relative humidity,
30 seconds or more at a temperature of 150 to 220 ° C., more preferably 1
At 70-200 ° C for 60 seconds or more.
10 minutes or more at 00 to 150 ° C, more preferably 110 to
In the case of dry heat at 135 ° C. for 15 minutes or more and a relative humidity of less than 90%, a temperature of 150 ° C. or more for 15 seconds or more, more preferably 1
It is 30 seconds or more at 70 ° C. or more. In addition, when a color loss promoting color paste is used, it is desirable to perform reduction washing with hydrosulfite or the like after printing and heat treatment in order to obtain a clear color. This reduction cleaning may be performed simultaneously with the subsequent alkali treatment.

In the heat treatment after printing in the present invention, the polyhydric alcohol ethylene oxide adduct in the printed portion acts as a weight loss accelerator and penetrates into the polyester fiber (A ₁ ) or (A ₂ ), When the fabric is alkali-reduced, the fiber is reduced from the existing portion of the organic sulfonic acid metal salt or the mixture of the organic sulfonic acid metal salt and polyethylene contained in the polyester fiber (A ₁ ) or (A ₂ ), and the fibril on the fiber surface is reduced. It promotes the formation of fluff which has been converted, and easily dissolves and removes the polyester fiber (A ₁ ) or (A ₂ ) in the printing portion when the alkali weight is reduced. In this heat treatment,
When the weight promoting color paste is used, the printed portion is colored with a disperse dye.

In the alkali treatment as the step (c) after the heat treatment in the present invention, an alkali metal hydroxide such as sodium hydroxide and potassium hydroxide, and an alkaline earth metal hydroxide such as calcium hydroxide and magnesium hydroxide are used. The fabric is immersed as an aqueous alkali solution using an alkali such as triethanolamine, diethanolamine, monoethanolamine or the like, if necessary. The alkali treatment can be changed according to the fineness of the polyester fiber constituting the fabric, the amount of the content, the composition ratio, the weight loss rate, and the like.
The alkali concentration is appropriately selected within the range of 1 to 500 g / liter. For example, when the polyester fiber (A ₁ ) or (A ₂ ) of the handle is formed with fibrillated fluff,
Polyester fiber (A
₁₎ or (if non shank polyester fibers (A ₁₎ or (A ₂₎ To form the fluff fibrillated to remove the A ₂₎ is a alkali concentration of the high concentration side, the temperature 60-120 C., preferably at 90-110.degree.

As the alkali treatment method, any known method generally applied to a polyester fiber cloth as a weight reduction process is applied. The alkali treatment time and the like are determined by the fineness of the polyester fiber constituting the fabric, the amount of the content, and the like. Composition ratio,
It can be appropriately changed according to the weight loss rate and the like. As a processing method,
It is preferable to apply a method in which a kneading action is added by contact between the fabrics or between the fabric and the processing apparatus wall during the treatment, and a liquid flow method using a liquid flow dyeing apparatus or the like is preferable.

By this alkali treatment, the metal sulfonic acid salt contained in the polyester fiber (A ₁ ) or the mixture of the metal sulfonic acid metal salt contained in the polyester fiber (A ₂ ) and polyethylene is applied to the printing portion of the weight loss promoting paste. The weight loss of the polyester fiber (A ₁ ) or (A ₂ ) accompanied by dissolution easily occurs, and the polyester fiber (A ₁ ) or (A ₂ )
A fibrilized fluff having a diameter of 0.05 to 5 μm and a length of 5 μm or more is formed on the surface of the cloth, and a handle having the fibrilized fluff on the surface of the fabric is obtained.

When two or more kinds of polyester fibers are used, at a higher alkali weight loss, the polyester fiber (A ₁ ) or (A ₂ ) is printed at the printing portion of the weight loss promoting paste.
As the polyester fiber (A ₁ ) or (A ₂ ) is dissolved and eaten away, only the polyester fiber containing no organic sulfonic acid metal salt or a mixture of the organic sulfonic acid metal salt and polyethylene remains, and the weight loss of the polyester fiber (A ₁ ) or (A ₂ ) is reduced. On the non-printed part of the weight loss promoting glue
Fibrillated fluff having a diameter of 0.05 to 5 μm and a length of 5 μm or more is formed on the surface of the polyester fiber (A ₁ ) or (A ₂ ), and a non-patterned portion having fibrillated fluff is obtained on the cloth surface. The degree of erosion or fibrillation due to the alkali reduction can be arbitrarily adjusted.

In the present invention, the fabric may be composed of only the polyester fiber having a high alkali weight loss rate, or two or more polyester fibers having different alkali weight loss rates including the polyester fiber having a high alkali weight loss rate. However, for the purpose of maintaining the strength of the fabric, other fibers that are not reduced or are not easily reduced may be mixed, and when other fibers are mixed,
It is necessary that the content be within a range that does not impair the texture of the fabric obtained by the method of the present invention.

In the method of the present invention, of course, after the step of alkali treatment, dyeing or printing is performed, so that the fibrilized fluff or the pattern of the watermark pattern formed by the extraction can be completely or partially removed. A variety of advanced design effects can be provided by a combination with various colorings.
