中文简体Post-processing of colored nylon yarn is one of the key steps in the dyeing process and is designed to further improve the appearance, feel and performance of the yarn.
Softening treatment: After dyeing, colored nylon yarn may be softened. This step is intended to improve the feel of the yarn, making it softer and more comfortable. Softeners are usually a type of surfactant that can affect the fiber surface at the molecular level and reduce friction between fibers, thereby improving the softness of textiles.
Finishing treatment: Finishing is a common post-processing step, the purpose is to make the fibers of colored nylon yarn more orderly and improve the appearance of the yarn. This can be achieved through the use of finishing agents, mechanical stretching or heat treatment. Finishing not only contributes to the tidy appearance of the yarn, it also improves the wrinkle resistance of the textile.
Anti-pilling treatment: Due to the special structure of nylon fiber, colored nylon yarn may easily produce lint. In order to reduce fluff, some special chemicals or processes are usually used in the post-processing stage to treat the fiber surface and improve the smoothness of the fiber.
Coating treatment: Some application fields have special requirements for colored nylon yarn, such as the need to increase waterproof performance or flame retardant properties. In this case, a coating treatment may be performed to achieve these functions by adding a special coating to the surface of the fiber.
Humidity conditioning treatment: Nylon fiber is sensitive to humidity and may deform due to changes in humidity. In order to improve the humidity response performance of colored nylon yarn, humidity control treatment can be carried out, using some humidity regulator or adding humidity responsive softener.
Styling treatment: After dyeing and post-processing, colored nylon yarn may require a styling treatment to ensure that the fiber maintains the desired shape and size. This step usually involves heat treatment to fix the structure of the fiber and improve the stability of the yarn.
Antistatic treatment: Nylon fiber has good electrical conductivity and is easy to accumulate static electricity. In order to reduce the impact of static electricity, some antistatic agents may be added in post-processing to improve the electrical properties of colored nylon yarn.
Final Inspection: The last step in post-processing is usually a final inspection. At this stage, producers will conduct a comprehensive inspection of colored nylon yarn to ensure that the product meets quality standards. Inspection includes appearance, color consistency, dimensional stability, etc.
Colored nylon yarn is a versatile and high-quality material that finds extensive use in various industries. Specifically, the 70D/2 nylon yarn is a notable variant that offers strength, durability, and aesthetic appeal. With its unique specification parameters, this yarn is designed to meet the diverse requirements of different applications, ranging from textiles to industrial manufacturing.
The colored nylon yarn with a specification parameter of 70D/2 refers to a yarn composed of nylon fibers with a denier (D) of 70 and a filament count of 2.
