▎ 摘　　要

NOVELTY - Antimony-free modified polypropylene yarn, comprises 20-40% polypropylene, 10-30% polypropylene fiber, 0.01-0.5% graphene, 0.3-5% inorganic filler, 30-50% anhydrous formic acid, 6-12% titanium compound, and 3-6% titanium catalyst. The content of anhydrous formic acid is 99.99%; and titanium compound is titanium dioxide. USE - Used as antimony-free modified polypropylene yarn. ADVANTAGE - The yarn has high strength, is non-toxic and pollution-free; and has low melting point, maintains the inherent network structure of the nonwoven fabric, and fully exerts the physical and chemical properties of the main fiber. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing antimony-free modified polypropylene yarn.
