Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides fabrics made of synthetic fibers or containing synthetic fibers, silk fabrics, and brocade brocade products that have excellent washing resistance, moisture absorption, water absorption, stain resistance, antistatic properties, and sewing properties. The present invention relates to a process for imparting excellent functions such as prevention of knitting yarn breakage by high-speed rotating sewing machine needles, stretch properties, and stretch recovery properties.

Synthetic fibers are hydrophobic, and when worn, compared to natural fibers, they tend to become sticky and stuffy due to perspiration, get stuck due to the generation of static ridges, cause discomfort such as rubbing sounds, and #1 attract stiffness and become dirty. Stretchability and stretch recovery due to knitting and weaving are slightly poor, easy to get oil stains and scratches, easy to re-adhere dirt when washed or dry-cleaned, and yarn breakage caused by high-speed sewing machine needles during sewing. However, there is a growing demand for greater stretchability and stretch recovery.

Efforts have been made to solve these drawbacks by using processing agents alone or in combination, but it has been impossible to satisfy all of these functions. Does it have a negative effect on any of the other functions even though it has an effect on the VC plus function? The result is as follows.

For example, in order to improve yarn breakage prevention, stretchability, and stretch recovery, which are essential conditions for knitted fabrics, it is common to use softeners or silicone-based dark fats that make yarns slippery. However, does it have a negative effect on hygroscopicity and water absorption? do.

The use of thermosetting resins for hand control also results in hygroscopic properties.

In the resin processing method of the present invention, a synthetic polymer substance having both hydrophilic groups and lipophilic groups in its molecular structure and two substances with different properties are added to a general fiber resin processing liquid. By skillfully combining and using Class 44I and above, and processing using ordinary equipment at low cost, it provides excellent wash resistance, moisture absorption and water absorption properties, as well as the desired texture, stretchability and stretch recovery properties. This is a processing method in which synthetic fibers and woven or knitted fabrics or cloth wire products containing synthetic fibers are treated with a resin, without damaging knitting yarn breakage prevention properties, antifouling properties, and antistatic properties.

These are synthetic fibers and woven and knitted fabrics containing them.

The synthetic polymer '14 used together with the resin processing fluid in the present invention includes one that is easily soluble in cold water and slightly soluble in hot water, and one that is slightly soluble in cold water and easily soluble in hot water. Any material may be used as long as it is effective as a fiber surface layer. For example, typical examples include methyl cellulose, ethyl cellulose, oxypropyl methyl cellulose, and carboxy methyl cellulose. Select synthetic polymer materials with appropriate degrees of etherification and polymerization, combine two or more types, and treat together with resin lJO processing agents.

The resin processing agent used in combination with rlLJ l-3ki 6 LJ ki may be any commonly used or known one.
