During the production and processing of cotton yarn, yarn breakage is often encountered, commonly known as "yarn breakage". Yarn breakage can greatly affect the productivity of winding and weaving, and reduce the quality of products. There are many factors that cause yarn breakage, such as uneven twist, long hairiness, uneven striping, as well as pre-treatment enzymes, refining and bleaching, dyeing/stripping, brittle loss of sulfur black dyeing, and excessive use of finishing silicone oil. Cotton fiber yarn breakage causes To prevent yarn breakage, the main problem is to solve the problem of yarn strength decline. During processing, fiber protection of yarn can significantly enhance the strength of yarn and solve the problem of insufficient strength of most yarns. The main product series are solid wax, fiber protection agent and other solutions. Cotton fiber strength protection method Fiber protectant: It is a large molecule fiber strength protection and repair protectant. Its core effectiveness is to evenly coat a protective film on the fiber surface, significantly reduce the friction between the yarn and processing equipment, improve the smoothness of the yarn, and reduce yarn breakage. It avoids the generation of flying feathers and improves the working environment. Fabric Strength Protector ultimately reduces yarn breakage during winding and weaving, significantly improves production efficiency, and results in uniform yarn stemming and a clearer and more uniform woven texture. It can also be used to improve the problem of poor top breaking strength and tearing strength of fabrics in knitting and weaving finishing processes. After treated with fiber protector (can you wax emulsion), it forms a uniform oil film on the surface, which increases the smoothness of the yarn, thus improving the friction conditions between yarns and between yarns and yarn guiding equipment, effectively reducing the static and dynamic friction coefficients between them, reducing the head breakage during winding and weaving, improving the efficiency of winding and weaving, and improving the environment without producing flying flowers and eliminating the need for workers to wear masks during production.
