Title:
NYLON-6 FIBER, AND MATERIAL-RECYCLED POLYCAPROAMIDE RESIN PELLETS AND METHOD FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/196407
Kind Code:
A1
Abstract:
The nylon-6 fiber is a nylon-6 for which at least 20 weight% of the fiber is recycled material, and is characterized by having a weight-average molecular weight (Mw)/number-average molecular weight (Mn), this being the dispersion ratio in the molecular weight distribution obtained by GPC measurement of the nylon-6, of not more than 3.4, and by having a z-average molecular weight (Mz)/weight-average molecular weight (Mw) of not more than 1.6. Provided is a material-recycled nylon-6 fiber that exhibits a good processability.
