AI Technical Summary

Technical Problem

Current technologies lack research on achieving a water-residue-free effect for polypropylene fibers, making it difficult to achieve an excellent water-residue-free effect while ensuring good mechanical properties of the fibers.

Method used

Water-free high-performance polypropylene fibers were prepared by using polypropylene chips, layered montmorillonite composite material and dendritic macroporous silica as composite fillers, and maleic anhydride-grafted polypropylene and silane coupling agent KH550 as composite compatibilizers, through high-speed mixing, melt spinning and stretching treatment.

Benefits of technology

It significantly improves the tensile properties of the fiber, reduces the water droplet diffusion time, and accelerates the drying rate, achieving a water-free effect on the fiber.

Abstract

The present application belongs to the technical field of high-performance polypropylene fiber, and particularly relates to a preparation method of water mark-free high-performance polypropylene fiber. The preparation method of the water mark-free high-performance polypropylene fiber comprises the following steps: S1, adding polypropylene chips, fillers, compatilizers, antioxidants and nucleating agents into a high-speed mixer to obtain premix by high-speed mixing; S2, melt spinning the premix obtained in step S1 to obtain the water mark-free high-performance polypropylene fiber. The polypropylene chips are used as the main material, and the interaction of the specific inorganic fillers and the compatilizers can significantly improve the tensile property of the fiber, effectively reduce the water drop diffusion time and accelerate the drying rate.
