Abstract

The invention relates to the technical field of manufacturing artificial filaments and analogues through polyvinyl chloride resin, in particular to a method for producing polyvinyl chloride fibers for artificial hair through ultrahigh pressure spinning, wherein the ultrahigh pressure spinning is adopted to convert cohesive energy of melts into system friction heat; material in a system is prompted to be heated uniformly; the utilization of heat resistant chlorinated vinyl chloride resin and heat stabilizers is reduced at the same time; the spinning fluidity is improved; the method chooses and utilizes the ultrahigh pressure melt spinning technology to prepare the polyvinyl chloride fibers, and the spinning pressure can reach 800 to 1000 kg/cm<2>; the application of the ultrahigh pressure spinning technology can improve the situations that the viscosity of vinyl chloride series resin is high and the fluidity is not good to a great extent; meanwhile, additives such as compatible chlorinated vinyl chloride resin matrix heat resistant chlorinated vinyl chloride resin can be omitted; in addition, the method enables the spinning process to be simplified and can improve the efficiency, and finished products have excellent performances.

Description

[technical field] [0001] The invention relates to the technical field of polyvinyl chloride resin manufacturing artificial filaments and the like, in particular to a production method of polyvinyl chloride fibers for ultra-high pressure spinning artificial hair. [Background technique] [0002] Polyvinyl chloride-based fibers are often selected as raw materials for artificial hair due to their advantages in flame retardancy, chemical resistance, and excellent tactility. Considering safety and comfort, etc. In terms of simplification of process procedures and environmental protection, melt spinning technology is often used to prepare polyvinyl chloride fibers. [0003] Polyvinyl chloride is easy to produce excessive thermal shrinkage due to heating in secondary processing, which is unfavorable for the use of finished silk. In order to better solve this problem, the patent CN1761778A discloses a kind of improved vinyl chloride resin and chlorinated resin. Compatibility between...
