Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a morphological stability using an epoxy compound of a cellulosic woven fabric having a tear strength that can withstand practical use, and having excellent texture and wash and wear property (hereinafter referred to as W & W property). It concerns processing methods.

[0002]

2. Description of the Related Art Cellulosic fiber materials have hitherto been widely used as clothing materials because they have better hygroscopicity and texture than synthetic fiber materials. However, the woven fabric of cellulosic fiber material has advantages such as good texture and excellent hygroscopicity as compared with the woven fabric of synthetic fiber material, but it is easily wrinkled, shrinks when washed, and is repeatedly washed. There are many drawbacks, such as the fiber becoming harder, and many processing methods have been proposed to solve this problem since ancient times.

For example, Japanese Patent Publication No. 49-18517 discloses a processing method in which formaldehyde vapor is used as a cross-linking agent, moisture and sulfur dioxide gas are used in combination as a catalyst, and sulfuric acid produced is used to proceed the reaction at high temperature. ing. However, this method has a drawback that the tear strength of the cellulosic fiber fabric is extremely reduced due to the influence of the generated sulfuric acid and the cross-linking and immobilization of the cellulosic molecules by formaldehyde. It is the actual situation that the decrease in strength is suppressed by the mixed fiber or the mixed knitting. Furthermore, "Processing Technology" magazine issued by Textile Co., Ltd. (Vol. 29, No. 6, 1994,
p. 389 to 395), the cellulose fibers are swelled uniformly by a mercerizing process using liquid ammonia so that the cross section of the cellulose fibers becomes almost circular, and the fibril intervals are narrowed to an average to give the cellulose fibers a soft texture. However, a method of applying formaldehyde resin to remove ammonia after that is outlined.
However, since all of these are processing methods using formaldehyde gas or low formaldehyde resin, formaldehyde remains on the fabric after processing, and there is a problem in terms of clothing hygiene and safety.

On the other hand, regarding non-formaldehyde processing of cellulose fibers, Journal of the Textile Society (Vol. 25, No.
11, 1969, P502 to 513, Vol. 26, N
o. 7, 1970, P124-137), a study using an epoxy compound is also published in "Dyeing Industry" magazine, Vol. 24, No. 2, 1976, P76-.
83, Vol. 24, No. 3,1976, P142-
147), studies using vinyl sulfone derivatives have been reported, but a method for processing cellulosic fabrics that has both tear strength and high morphological stability to withstand practical use has not yet been established. It is the actual situation.

[0005]

DISCLOSURE OF THE INVENTION The present invention has a high W & W property, which is an index of morphological stability, and a tear strength, and does not use formaldehyde, does not cause toxicity to the human body, and is excellent in safety. The present invention provides a morphologically stable processing method for textiles.

[0006]

The present inventors have arrived at the present invention as a result of extensive studies to solve the above problems. That is, according to the present invention, a cellulosic fabric is prepared by modifying a nonionic silicone softening oil, a nonionic urethane resin and a nonionic urethane prepolymer modified product 3
It is a novel morphological stable processing method for cellulosic fabrics, which is characterized in that the same bath treatment is carried out with a mixed dispersion solution of at least one of the above and an epoxy compound.

The cellulosic woven fabric of the present invention refers to a woven fabric woven from cellulosic fibers obtained by individually or blending cellulosic fibers such as cotton, rayon, and polynosic. However, it can also be applied to fabrics such as knits.

In the present invention, for the purpose of preventing a decrease in tear strength, a conventional mercerized or bleached cellulosic fabric is added to a nonionic silicone softening oil, a nonionic urethane resin and a nonionic. Of a modified urethane prepolymer, alone or in combination of two or more,
Used by mixing and dispersing with epoxy compound. Since the mixed solution is to produce or fix a polymer film on the fiber surface by a heat treatment at the same time as a crosslinking reaction, the present invention provides
It has an effect of preventing a decrease in tear strength due to crosslinking.
In addition, the nonionic silicone-based softening oil and nonionic urethane resins and modified nonionic urethane prepolymers form an ion complex with a metal borofluoride salt used as a catalyst for epoxy compounds,
It is preferable that it is water-insoluble or does not precipitate by remarkably disappearing the dispersion composition, and therefore it is essential to use a nonionic one having no anionic or cationic dissociative group.
That is, examples of the nonionic silicone-based softening oil used in the present invention include methylhydrogenpolysiloxane, α, ω-dihydroxymethylpolysiloxane, dimethylpolysiloxane, and the like. Is a nonionic resin obtained by polymerizing a urethane prepolymer with a chain extender, and a modified nonionic urethane prepolymer is an isocyanate group at both ends of the urethane prepolymer. It is preferable that the above is modified with a phenol group or a ketone group. Although the same effect can be obtained by using a polyethylene emulsion, it is not preferable because it has strong water repellency and has drawbacks such as generation of water spots after finishing.

Considering that the concentration of the modified liquid of the nonionic urethane resin and / or the nonionic urethane prepolymer on the cellulosic fabric does not impair the texture of the cotton and prevents the tear strength from decreasing. It is preferable to use 1 to 5% by weight, including the case of using them alone or as a mixture.
The treatment liquid concentration of the nonionic silicone-based softening oil is preferably 1 to 5% by weight in consideration of texture and water absorption. Further, the treatment concentration when these are mixed and used is a nonionic silicone type softening oil,
As for the treatment concentration range of the nonionic urethane-based resin and the modified product of the nonionic urethane prepolymer, if the total value of the concentrations of the two or three types is within the range of 1 to 5% by weight, three types can be freely combined. Can be matched.

The epoxy compound used as the cross-linking agent is ethylene glycol diglycidyl ether or diethylene glycol diglycidyl ether, which is highly safe and has a well-balanced anti-wrinkle property and shrink-proof property in both dry and wet conditions by ordinary impregnation, drying and heat treatment. It is preferable in that the property is obtained. The concentration of the treatment liquid can be appropriately set according to the desired wrinkle resistance and shrink resistance, and can be usually used in the range of 100 to 250 g / l, but the so-called no ironing level W & W property of 3.3 or higher. In order to obtain the above, it is preferable to use it in the range of 150 to 250 g / l. On the other hand, the wrinkle resistance and washing resistance of the processed product are better when the treatment concentration of the crosslinking agent is higher,
In order to retain the texture peculiar to the material used for the woven fabric and keep the tear strength (latitude) of 750 g or more, which is practically usable, the treatment concentration of the crosslinking agent is preferably used in the range of 150 to 200 g / l.

An acid or an alkali can be used as a crosslinking catalyst for the epoxy compound, but an acid catalyst such as a strongly acidic metal salt such as zinc borofluoride or magnesium borofluoride is generally used.

The processing of the cellulosic fabric is carried out by using a nonionic silicone softening oil, or a modified nonionic urethane resin and / or nonionic polyurethane, or a nonionic silicone softening agent. The woven fabric is dipped and impregnated in a mixed solution prepared by mixing and adding an epoxy compound to a modified product of an oil agent and a nonionic urethane-based resin and / or a nonionic urethane prepolymer, and a squeezing ratio of 8 with a roller.
Squeeze at 0%, dry at 80-120 ° C, then 150-1
The heat treatment may be performed at 70 ° C. The heat treatment time is not particularly limited as long as it is sufficient for the crosslinking reaction to proceed sufficiently, and can be appropriately set depending on the basis weight of the cellulosic fabric or the like.

Next, the finishing process such as washing with water and drying after the soaping process, and treatment with a finishing oil agent are not particularly limited and may be carried out by a generally used method. Further, a fluorescent whitening agent can be used to further increase the whiteness of the woven fabric, but in this case, the fluorescent whitening agent is used in the same bath as the finishing oil agent in the same bath as in the case of ordinary finishing. It suffices to add an appropriate amount of the agent for treatment. Since the method of the present invention treats with a non-formaldehyde-based chemical, there is no problem in hygiene, and it has a tear strength that can withstand practical use that could not be achieved in the past, and at the same time it has a well-balanced wrinkle resistance and shrinkage resistance in both dry and wet conditions. It is possible to obtain a cellulosic woven fabric which has excellent hygroscopicity and texture and has excellent W & W property.

EFFECTS OF THE INVENTION The method for stabilizing the morphology of a cellulosic fabric of the present invention has the above-mentioned constitution. The cellulosic fabric has a nonionic silicone softening oil, a nonionic urethane resin and a nonionic resin. A modified product of the urethane prepolymer is used alone or in combination of two or more, and a cross-linking treatment is carried out as a mixed solution in which ethylene glycol diglycidyl ether or diethylene glycol diglycidyl ether of an epoxy compound is mixed, and therefore, the conventional processing method is used. Compared with the morphologically stabilized product of the obtained cellulosic woven fabric, it has high W & W property and at the same time has sufficient tear strength to endure practical use.
