Dyeing-free terry fabric and production method thereof

Abstract

The invention belongs to the technical field of textile, and particularly relates to a dyeing-free terry fabric and a production method thereof. A terry yarn of the terry fabric is blended yarn of, inpercentage by mass, 5%-40% of dope-dyed fiber and 60%-95% of cotton fiber, wherein the dope-dyed fiber is made of regenerated polyester fibers or regenerated cellulose fibers or polylactic acid fibers. The production method comprises the following steps that cotton assorting is conducted, spinning is conducted, gray fabric weaving is conducted, then dyeing and finishing are conducted, and aftertreatment is conducted to obtain the product. The comprehensive color fastness performance of the dyeing-free terry fabric is better than that of a traditional water bath dyed terry fabric product, thelight fastness, the color fastness to chlorine and the color fastness to washing of the dyeing-free terry fabric are more outstanding than those of the traditional water bath dyed terry fabric product, and the production method has social and ecological benefits of environmental protection, low carbon, low emission, sustainability and the like.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a dye-free terry fabric and a production method thereof. Background technique [0002] At present, traditional terry fabrics are purely spun from natural fibers or blended with other fibers. In order to express the color requirements of the terry fabric, the yarn needs to be dyed in advance or dyed in the original color gray cloth process. [0003] Due to the difference in fiber dyeing rate, it is necessary to carry out scouring, bleaching, pre-treatment, dyeing, post-finishing and other treatments on the above-mentioned fibers, resulting in cumbersome production process and a large amount of scouring and dyeing wastewater. In the dyeing process, a high temperature and high pressure dyeing environment is often required, which increases the consumption of steam, resulting in high production costs, and serious waste water pollution, which is very harmful to the enviro...

AI Technical Summary

Problems solved by technology

This idea is indeed more suitable for the differentiated customization of small customers, but the production cost and organization are very difficult, especially the blending of two or more color-spun regenerated cellulose fibers and pre-treated cotton fibers has its own problems. Great technical difficulty, and strict technical requirements and equipment requirements for downstream spinning factories, especially the large gap between automatic color matching and color actual effect, it is difficult to accurately align the color required by customers; and the above patents use color Spun regenerated cellulose fibers are blended with pre-treated cotton fibers. In this method, the yarn processing plant must have equipment for dyeing loose fibers and corresponding drying equipment. The production of cotton fibers obtained by this method The efficiency is low. After the cotton fiber is pre-treated and dried, it occupies a large area, which brings problems to fiber storage. At the same time, if the post-treatment of the fabric does not carry out the water and setting treatment, the shrinkage rate of the fabric after washing in the warp and weft direction is relatively large, which is very It is difficult to meet the requirements of customers. Therefore, the production efficiency of the color-spun yarn and color-spun fabric produced by this method is lower than that of the product that is pre-treated after weaving, the production is difficult, and there is no advantage in energy and water conservation.
