Regenerated Nylon 6 is also called nylon 6 recycled material, which is generally produced by melting and granulating nylon yarn, nylon yarn or nylon cloth, because nylon 6 not only has good wear resistance, heat resistance, oil resistance and chemical resistance And processability, but also has dimensional stability and excellent mechanical properties, is widely used in automotive industry parts, gears, bearings, fan blades, pump blades, fishing gear, bicycle parts and some precision engineering accessories.
4.cn112853534a discloses a fiber manufacturing process, especially relates to a regenerated nylon 6 fiber manufacturing process, which includes the following steps: Step 1, pulverizing nylon 6 waste; Step 2, adding catalyst and ethanol and dichloroethylene A mixed solvent of alkane; Step 3, after the dissolution, filter the undissolved solids in the solution; Step 4, cool and crystallize the nylon 6 in the filtered solution at a certain temperature into a nylon 6 solid; Step 5, place the nylon 6 solid in Drying in an oven at 100-120° C. for 3-4 hours to make the water content less than 5%; Step 6, adding additives to obtain a mixture; Step 7, melt spinning to obtain regenerated nylon 6 fibers. The invention uses nylon 6 waste to produce regenerated nylon 6 fiber, which realizes the recycling of nylon 6 waste and fully avoids resource waste and environmental pollution.

3. However, nylon 6 will degrade during processing, resulting in the loss of molecular weight, affecting the melt strength and processability of the polymer, resulting in the inability of recycled or recycled materials to be used in occasions with high performance requirements, and even possible Being treated as waste is not in line with today's theme of green and low-carbon development. Therefore, how to recycle recycled nylon 6 materials to avoid resource waste and environmental pollution has become a hot research issue in recent years.
