Nylon 6 and Nylon 66 The more common nylon products on the market are nylon 6 and nylon 66. Nylon 6: The full name is polycaprolactam fiber, which is polymerized from caprolactam. Nylon 66: The full name is polyhexamethylene adipamide fiber, which is polymerized from adipic acid and hexamethylene diamine. Next, Yizhengzhi, a hot melt yarn manufacturer, will talk to you about nylon 6 and nylon 66.
Generally speaking, nylon 66 has a better hand feel than nylon 6, and the comfort of nylon 66 is also better than nylon 6, but it is difficult to distinguish between nylon 6 and nylon 66 on the surface.
The common characteristics of nylon 6 and nylon 66: poor light resistance. Under long-term sunlight and ultraviolet light, the intensity decreases and the color turns yellow; its heat resistance is not good enough. It will change color after 5 hours at 150°C. Yellow, the strength and elongation are significantly reduced, and the shrinkage rate is increased. Nylon 6 and 66 filaments have excellent low temperature resistance, and their resilience does not change much below minus 70°C. Thermal fuse manufacturers say that its DC conductivity is very low, and static electricity is easily generated due to friction during processing. Its conductivity increases with the increase of moisture absorption, and increases with the increase of humidity according to exponential function rules. Nylon 6 and 66 filaments have strong resistance to microbial effects, and their resistance to microbial effects in silt water or alkali is second only to chlorine fiber. In terms of chemical functions, nylon 6 and 66 filaments have alkali resistance and reducing agent resistance, but have poor acid resistance and oxidant resistance.
The above is what Yizheng Zhihe, a thermal fuse manufacturer, has compiled and released for you about nylon 6 and nylon 66, mainly the above parts. I hope it will be helpful to everyone. zhejiang ocean star Co., Ltd. specializes in the production and sales of various thermal fuse wires (nylon thermal fuse wire, polyester thermal fuse wire, 3D shoe upper thermal fuse wire, etc.), with quality assurance and factory direct sales. Welcome everyone to inquire and order.
