Description

Six-layer pure cotton untwisted textile and production process thereof

Technical Field

Background

Along with the improvement of living standard, the quality requirements of people on textile articles for daily use are increasingly improved, and especially the performances of daily textile products such as bath towels and towels which directly contact the skin have higher-level requirements. The existing home textile products are divided into twisted textile products and untwisted textile products. The non-twisted textile is formed by weaving non-twisted yarns, can be directly woven by protofilaments of cotton, bamboo and the like without being bound by the twisted yarns, is thick and compact, has good fluffy feeling, and has the characteristics of skin friendliness and strong water absorption when in use; however, the untwisted fabrics have low strength, and the problem of fiber breakage can occur after multiple times of washing, so that the phenomenon of hair falling can occur at light times, and the damage to the surfaces of the fabrics can be caused at heavy times, thereby affecting the service life. The twisted textile is formed by weaving twisted yarns, so that the use strength is ensured, but the skin-friendly property is poor, the textile becomes hard after being repeatedly washed, and the use experience is poor.

In addition, the dyeing step in the conventional textile process has a great influence on the quality of the finished product. Especially, in the dyeing process of untwisted textiles, the treatment operation of removing the water soluble yarns is needed before dyeing, and then the textile can enter the dyeing operation after efficient rinsing, otherwise, the color fastness is poor, and the decoloration phenomenon appears in the use process of the textiles. In the prior art, a natural diffusion type low-efficiency untwisting and dyeing method is adopted by the dyeing machine, so that water-soluble yarns are not thoroughly removed, and the dyeing quality is influenced to a certain extent.

In the soaping process after dyeing, because the existing soaping agent is not suitable for soaping and cleaning twisted and untwisted compound fabrics, the applicant also develops a special soaping agent which can thoroughly clean residual dyes on the fabrics after the dyeing process, but does not influence the color fastness of the fabrics, and the fabrics after soaping still keep preset colors and can effectively improve the product quality.
