Abstract
Description
technical field
[0001] The invention belongs to the field of textiles, in particular to a dyeing method for modifying polypropylene fibers or fabrics by using a low-temperature plasma graft polymerization method. Background technique
[0002] As we all know, polypropylene fiber is one of the five major fibers in the world. It has rich sources of raw materials, simple manufacturing process, low cost (about half of polyester), and has incomparable advantages of ordinary fibers, such as light texture, high strength, good elasticity, Corrosion resistance, no pilling, moisture conductivity, good warmth retention, etc. However, since the polypropylene fiber macromolecule has an extremely regular isotactic structure and does not contain any dyeable groups, this fiber with very good wearing properties cannot be dyed at all, which seriously hinders the use of this fiber in clothing. development in this vast market. Therefore, the solution to the dyeable prob...
