Abstract

The invention provides a hydrophilic polypropylene composition. A hydrophilic polypropylene material is prepared by adding a polar compound, a surfactant and a compatibilizer to the polypropylene base material for modification. The material can be widely used in sanitary and medical nonwovens and absorbent fiber products, as well as industrial products such as filters and battery separators, broadening the application fields of polypropylene and increasing the added value of products.

Description

technical field [0001] The invention belongs to hydrophilic fiber, which can be widely used in various battery internal separators, filter materials, non-woven fabrics for medical and sanitary use, and absorbent fiber products, etc. It has water absorption and hydrophilic effects; antistatic; reduces friction; increases fabric Features such as softness and hand comfort. Background technique [0002] Materials used in the hydrophilic field are usually polar hydrophilic materials such as polyamide, polyvinyl alcohol, polyacrylamide, polyethylene glycol, and sodium polyacrylate. Materials other than polyamide have a low melting point and are degraded at high temperatures, so they are not suitable for places with high processing and use temperature requirements. Although polyamide has a high processing temperature, it is used as a battery diaphragm material and has poor electrical insulation, which affects the service life of the battery. The hydrophilic polypropylene material...
