The Chinese cotton textile industry association, based on the "China Cotton Textile Industry Association standard management rules", has been studying the second batch of group standards, namely "combed polyester colored yarn" and "cationic modified cotton fiber".
The leading unit of the "combed polyester yarn" standard is Nantong Shuang Hong Textile Co., Ltd. Nowadays, the application fields of non cotton fiber are widening. Due to the inherent quality inherent factors such as curling and defects of raw polyester yarns or regenerated polyester yarns, finished yarns are difficult to meet the quality requirements of high-end products. The ordinary polyester fiber or recycled polyester fiber can be changed through the chemical fiber combing process, which can change the fiber straightness, reduce the content of raw material defects and enhance the spinnability, so that ordinary polyester or low quality and low price polyester raw materials can meet the quality requirements of the high-grade field. The group standard of combing polyester colored yarn provides guidance for the supplier and the buyer to sign contracts, provides basis for production enterprises to formulate internal control standards, and provides technical support for the high-end development of polyester industry.
The leading standard of the "cationic modified cotton fiber" is Shaoxing Mai Bao Technology Co., Ltd. In order to fully develop and utilize cotton fiber and improve the added value of cotton fiber textile, the modified cotton fiber developed by the concept of green environmental protection has attracted more and more attention. Cationic modified cotton fibers are modified by cationic chemical grafting. The dyed yarns are characterized by rich colors, bright colors, good color fastness, and environmental protection. They are mainly used in knitted fabrics and some woven fabrics. The proposal of "cationic modified cotton fiber" is a combination of disciplines and industrial development. It can realize the numerical value of the technical indicators of products, provide a plan for grading the quality of modified cotton fibers, promote the improvement of cotton fiber technology, improve the quality of products, and improve the testing and testing methods, and speed up the process of product development, industrialization and market promotion.
