Problems solved by technology

However, there are disadvantages in these products: PVC-based fibers have poor thermal stability and fluffy feeling, high thermal shrinkage rate, and are prone to yellowing; protein-based fibers have poor heat resistance; PAN-based fibers have poor thermal stability and flame retardancy; polyester-based fibers Fibers generally have poor flame retardancy; human hair has limited sources
The disadvantage of this invention is that the thermal stability of the prepared resin is low, and it is only suitable for wet spinning

Abstract

The invention discloses a PVDC (polyvinyl dichloride) composition for spinning. The PVDC composition for the spinning comprises the following components in parts by weight: 20 to 30 parts of vinylidene chloride monomers, 3 to 9 parts of vinyl chloride monomers, 0.06 to 0.3 parts of initiator, 0.02 to 0.04 part of pH (potential of hydrogen) value buffer conditioning agent, 0.01 to 0.05 part of dispersing agent, 0.5 to 0.8 part of plasticizer, and 0.05 to 0.2 part of lubricating agent. The PVDC composition provided by the invention has favorable heat stability and spinning processing performance.

Description

technical field [0001] The present invention relates to a PVDC composition, more specifically, the present invention relates to a PVDC composition for spinning. Background technique [0002] With the economic globalization and the change of people's life and aesthetic concept, wearing wigs has become a fashion. People have higher requirements for the quality and craftsmanship of wigs (color, feel, curl, bulk, heat resistance, flame retardancy, strength). The materials currently on the market for preparing artificial hair mainly include polyvinyl chloride (PVC)-based fibers, protein-based fibers, polyacrylonitrile (PAN)-based fibers, polyester-based fibers, and human hair. However, there are disadvantages in these products: PVC-based fibers have poor thermal stability and fluffy feeling, high thermal shrinkage rate, and are prone to yellowing; protein-based fibers have poor heat resistance; PAN-based fibers have poor thermal stability and flame retardancy; polyester-based fi...
