Description

Six-layer pure cotton untwisted textile and production process thereof

Technical Field

The invention belongs to the technical field of special fiber spinning technology and equipment, and particularly relates to a six-layer pure cotton untwisted textile and a production technology thereof.

Background

With the improvement of living standard, the quality requirements of people on textile living goods are increasingly improved, and especially, the requirements of higher levels are met for the performance of daily textile products such as bath towels, towels and the like which directly contact skin. Existing home textile products are divided into two types, namely twisted textiles and non-twisted textiles. The non-twisted textile is formed by non-twisted yarn, can be directly woven by raw silk such as cotton, bamboo and the like without twisting and binding, and has the characteristics of thick, tight and good fluffiness, and has skin-friendly and strong water absorption when in use; but the untwisted textile has lower strength, the fiber breakage problem can occur after multiple times of washing, the phenomenon of hair falling occurs when the untwisted textile is light, and the damage of the surface of the textile is caused when the untwisted textile is heavy, so that the service life is influenced. The twisted textile is formed by twisting twisted yarns, so that the use strength is ensured, but the skin-friendly property is poor, the textile can be hardened after repeated washing, and the use experience is poor.

In addition, the dyeing step in the traditional textile technology has a great influence on the quality of finished products. Especially in the dyeing process of non-twisted textiles, the treatment operation of removing water-soluble yarns is needed before dyeing, and then the water-soluble yarns can enter the dyeing operation after high-efficiency rinsing, so that poor color fastness is easy to occur, and the decolorization phenomenon occurs in the use process of the textile. The dyeing machine in the prior art adopts a natural diffusion type low-efficiency untwisting and dyeing method, so that the water-soluble silk is not thoroughly removed, and the dyeing quality is affected to a certain extent.

In the soaping process after dyeing, the applicant also develops a special soaping agent which can thoroughly clean residual dye on the fabric after dyeing process due to the fact that the existing soaping agent is not suitable for the soaping cleaning of twisted and untwisted compound fabric, but does not influence the color fastness of the fabric, the fabric after soaping still keeps preset color and luster, and the product quality can be effectively improved.
