▎ 摘　　要

NOVELTY - A knitted yarn comprises 65-75 pts. wt. polyamide-based biomass graphene fiber and 25-35 pts. wt. soybean fiber. USE - Knitted yarn for textiles. ADVANTAGE - The polyamide-based biomass graphene antibacterial and anti-ultraviolet semi-worsted knitting yarn has the function of inhibiting Staphylococcus aureus and Escherichia coli and also ensures the soft touch of the yarn. The method overcomes the technical bottleneck of the production of the polyamide-based biomass graphene antibacterial and anti-ultraviolet semi-worsted knitting yarn. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the knitted yarn, which involves polyamide-based biomass graphene fibers, soybean fibers, hair oil and antistatic agent having amount of 1%.
