Abstract

This invention relates to a method for modifying dye of surface of a polypropylene material, which first of all uses different gas plasma to process the fiber material including: preprocessing the surface of the fiber material then processing the material with N2, H2 and O2 plasma and then uses graft to process it including: applying a tree-like monomer graft liquid to modify the processed polypropylene material.

Description

technical field [0001] The invention belongs to a material modification treatment method, in particular to a method for surface modification and modification of polypropylene (polypropylene fiber) dyeing, and belongs to a material treatment method characterized by its physical properties or the effects produced. It is mainly used for the treatment of polypropylene material before dyeing. Background technique [0002] Polypropylene (PP) material is a semi-crystalline thermoplastic material. It has high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid and alkali corrosion. It is widely used in industry and is one of the common polymer materials. [0003] Among polypropylene (PP) materials, polypropylene (polypropylene fiber) is an important type of synthetic fiber that appeared in the 1960s. Since it came out in 1957, it has achieved great development worldwide. One of the fourth largest fiber varieties developed after the...
