Problems solved by technology

However, polyamide fibers have poor heat resistance and light resistance, poor retention, and poor hygroscopicity and dyeability. The traditional nylon dyeing process is very complicated, and the dyeing effect on natural dyes is not good, especially The dyeing effect of extra-dark color is particularly poor, so it is necessary to study a nylon extra-dark dyeing process, so as to improve the color fastness and environmental protection performance of nylon dyeing

Abstract

The invention provides a chinlon extra dark color dyeing process. Firstly, a calcium carbonate solution is used for performing surface grinding on chinlon yarns, the grinding strength and the particlesize of calcium carbonate are controlled to prevent too much impact on the strength of the chinlon yarns, meanwhile, a large number of pits are formed on the surfaces of the smooth chinlon yarns, andthe combination of subsequent dyes and fibers is facilitated; and the natural dye used for dyeing and a dyeing auxiliary are stirred uniformly to obtain the natural dye liquor, and after dyeing by using a dip dyeing process, the dyeing can be completed by soaping and high-temperature fixation. According to the chinlon extra dark color dyeing process provided by the invention, although the bath ratio of the calcium carbonate solution treatment used in the invention is relatively high, the calcium carbonate solution can be used repeatedly; and in the subsequent dyeing process, one-step processis carried out, and then soaping and high-temperature fixation treatments are carried out. According to the dyeing method provided by the invention, post-treatment is not needed after dyeing, the procedure is greatly simplified, and the obtained ultra-dark yarn has high soaping color fastness; and compared with a traditional dyeing method, the effect of energy saving and environmental protection is remarkable.

Description

technical field [0001] The invention relates to the technical field of textile dyes, in particular to a nylon extra-dark color dyeing process. Background technique [0002] In human history, natural fuels have made indelible contributions to beautifying people's lives. Since the end of the 19th century, due to the rapid development of synthetic dyes, natural fuels have basically withdrawn from the field of fabric dyeing. With the increasing awareness of human environmental protection and the increasing concern for their own health, the harm of some synthetic dyes to human health and the ecological environment has become more and more noticeable. With the improvement of modern technology level, especially the improvement of modern manufacturing level, people have higher and higher requirements for the safety and health care of the clothing industry, and natural dyes have begun to be valued by people again. Animal and vegetable dyes in natural dyes are extracted from organis...
