Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath softener composition for fibers which prevents the occurrence of threads and wrinkles which occur during the processing such as scouring and dyeing of fibers. In the present invention, the term "fibers" is used to include yarn, cloth, and textile products.

[0002]

2. Description of the Related Art In the process of processing textile products, since the occurrence of wrinkles affects the quality of the obtained fiber products, great care has been paid to suppressing or preventing the occurrence of wrinkles. This thread wrinkle is a problem relating to all fiber products such as synthetic fibers such as polyester, nylon and acrylic, regenerated fibers such as rayon and polynosic, natural fibers such as cotton and wool, and mixtures thereof. In addition, as a form of a fiber product, it is frequently generated in a woven fabric and is often found in a knitted fabric. Furthermore, in the past, cheese (thread wound on a bobbin) did not cause thread wrinkles and was not considered to require much attention. However, in recent years, cheese has been prevented from becoming out of shape, and untwisting during rewinding has been improved. Some of the techniques for preventing wrinkles have been applied for such purposes.

[0003] On the other hand, since it is difficult to remove the wrinkles once generated in the fiber product, how to reduce the occurrence of the wrinkles is the most important issue in each processing step. It has been said that this wrinkle is particularly likely to occur in the dyeing process among various fiber processing processes, but it also occurs in the scouring process which is the pre-dyeing process and the soaping and washing processes which are the post-dyeing processes. Attention must be paid to these steps in some cases. In recent years, it is said that the occurrence of wrinkles and wrinkles is also feared in the flexible processing process,
This wrinkle problem is a problem that needs to be noted during the entire fiber processing.

[0004] In the fiber processing step, various chemicals and equipment are used in order to smoothly and rationally advance the processing step. However, in order to prevent or reduce the occurrence of wrinkles, treatment is performed. The choice of process and equipment is important,
It is no exaggeration to say that the type of equipment in each process determines the quality of the finished textile product in that process. In processes such as scouring and dyeing, a liquid jet dyeing machine is mainly used in recent years. The liquid jet dyeing machine has various processing advantages, but on the other hand, it has a drawback in that, in terms of structure, the occurrence of wrinkles in the treated cloth increases.

Therefore, bath softeners are used to prevent or reduce the wrinkles generated during the fiber processing step as described above. Nonionic polymers such as higher fatty acid esters, esterified products of polyoxyethylene alkylamine and fatty acids, higher alcohol esters of trimellitic acid, and polyacrylamide have been used as such softeners in the bath. . However, these softeners in the bath have a so-called hydrophilic surface, such as cellulosic fibers, such as cotton and rayon polynosic, while having a certain effect of preventing wrinkles, but fibers having a hydrophobic surface, for example, It is also a fact that synthetic fibers such as polyester, nylon and acrylic have insufficient effect of preventing wrinkles and wrinkles, and a softening agent in a bath corresponding to these synthetic fibers is required.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and in particular, it is an object of the present invention to provide a bath suitable for synthetic fibers, which can suppress or prevent the occurrence of wrinkles of fibers generated in the processing steps of various synthetic fibers.
