Hydrophilic non-woven fabric Functional non-woven fabrics

Chemical modification mainly changes the molecular structure of PP, adding hydrophilic groups on the macromolecular chain, and then changes its hygroscopicity, mainly copolymerization, graft, crosslinking, chlorination and other methods.Physical modification mainly changes the higher order structure of molecules to achieve the purpose of improving the hydrophilic effect, which mainly consists of blending modification (i.e., before spinning) and surface modification (i.e., after spinning).Blend modification (pre-spinning modification) can be divided into master batch method, total granulation method and pre-spinning injection method according to different time period of modification additive.Common masterbatch is an important method of producing hydrophilic nonwoven fabric by nonwoven manufacturers.First, ordinary hydrophilic additives are made into jellyfish pellets, and then mixed with PP to spin and melt into cloth.Advantages: simple production, do not need to add any equipment, and…
