To add light stabilizer and antioxidant, is to improve its light resistance to aging. As the light stabilizer on the absorption capacity of ultraviolet light is stronger than the polymer base, which contains the ability to trigger the absorption of impurities in the optical reaction, while the antioxidant is to provide hydrogen out of the oxidation process to produce active free radicals, to prevent poly Progress of Autoxidation Chain Reaction Process of Propylene. The photostability of PP macromolecules can be improved by the interaction of the two. Molecular weight tensile strength with the aging time of the change is basically the same, which is sufficient to explain the high-strength polypropylene fiber ultraviolet aging will result in significantly lower molecular weight. Solution spinning: select the appropriate solvent, the fiber-forming polymer dissolved into a spinning solution, or first made of soluble polymer intermediates, and then dissolved into a spinning solution, and then spinning. Viscose, vinylon, acrylic multi-use this method. Solution spinning according to different conditions of solidification is divided into wet spinning and dry spinning. Wet spinning: The fiber-forming macromolecular polymer is dissolved in a solvent to prepare a spinning solution. The spinning solution is sprayed from a spinneret and discharged into a coagulation bath. Since the solvent diffusion and coagulation in the viscous filament stream The agent penetrates into the mucus filament stream, allowing the filament stream to solidify into filaments. Dry spinning: the use of volatile solvents on the polymer to dissolve, made of viscous liquid suitable for spinning. The spinning mucus is extruded from the spinneret to form a filament stream, and the solvent in the filament stream is rapidly volatilized and solidified by a hot air jacket. Melt spinning: to see the name of the melt spinning is to heat the polymer to the appropriate temperature above the melting point to prepare the melt, the melt extruder by the screw, the metering pump out of the nozzle hole, so that The formation of small streams into the air, the condensed and become thin.

High-strength polypropylene fiber is an important part of chemical fiber products, so it directly affects the quality of our product quality problems. It is also our company mainly engaged in one of the products, its quality selection is our every consumer has been focusing on the issue.
