Description

  The present invention relates to a cellulosic fiber fabric that is less likely to be wrinkled even after it has been wet with water such as washing.

Cellulosic fibers such as cotton have been used in various clothing mainly from underwear. In recent years, shrink-proof processing that eliminates shrinkage due to washing, which is a major drawback of cotton, has been developed, and its use continues to expand (Patent Documents 1 and 2).
However, although the large shrinkage of cotton products due to washing has been improved, it still has the disadvantage that when the cellulosic fibers are wetted with water and dried, the texture is greatly changed.
In order to eliminate this drawback, a softening agent or the like is added at the time of washing. However, the addition of the softening agent is required every time washing is performed, and improvement has been desired.

In addition, cotton clothes have been developed for use in work clothes, jumpers, anoraks, as well as for casual wear in fashion, windbreakers and ski wear, etc. However, the performance of water repellency applied to these cellulosic fibers is significantly reduced by washing.
JP2001-248068 JP 2003-49362 A

  The present invention solves the above-mentioned problems, and has a water-repellent performance excellent in washing durability while being a cellulosic fiber, and is a cellulosic fiber fabric having an excellent texture that does not become sticky even when wet. Is to provide.

The present inventors diligently studied to solve the above problems, and invented the following cellulosic fiber fabric and a method for producing the same.
The cellulosic fiber fabric of the present invention is characterized in that a dichlorotriazine compound and a water repellent are added to cellulosic fibers.
The dichlorotriazine compound is represented by the following general formula (1)

It may be a compound represented by

Moreover, the manufacturing method of this invention is a manufacturing method of the said cellulose fiber fabric, Comprising: After providing a dichloro triazine type compound to a cellulose fiber, it provides a water repellent.
Moreover, the provision method of a dichloro triazine type compound is good to provide a dichloro triazine type compound to a cellulose fiber in the processing liquid of 20 to 85 degreeC containing a dichloro triazine type compound.
In addition, after the dichlorotriazine compound is applied to the cellulose fiber in a treatment liquid at 20 ° C. to 60 ° C. containing the dichlorotriazine compound, the method for applying the dichlorotriazine compound is further performed at 60 ° C. to 85 ° C. The method for producing a cellulosic fiber according to claim 2 or 3, wherein the heat treatment is performed in a treatment liquid at 0 ° C.

  According to the present invention, it has excellent shrinkage resistance, excellent water repellency and washing durability, and it is difficult to cause deterioration of the texture due to wrinkle even if it is dried after being wet, especially after water repellency is lowered. Even so, it is possible to provide a cellulosic fiber fabric in which the deterioration of the stickiness hardly occurs.

The present invention is a cellulosic fiber fabric obtained by adding a dichlorotriazine compound and a water repellent to a cellulosic fiber. The cellulosic fiber of the present invention is a cellulose derived from natural fibers such as cotton and hemp. Recycled fibers such as system fibers, rayon, polynosic, modal, cupra, and lyocell may also be used. Further, it may be blended, blended, or woven with synthetic fibers such as polyester and nylon and semi-synthetic fibers such as acetate, and is not particularly limited.
