Polypropylene (pp) nonwoven fabrics(Hydrophilic Nonwovens On Sales) are widely used due to their excellent properties, simple processing methods and low price. Especially in recent years, it has been widely used in the fields of health care, clothing, packaging materials, wiping materials, agricultural covering materials, geotextiles, industrial filter materials, etc., and has a tendency to replace its traditional materials.

Since pp is a non-polar structure and substantially free of hydrophilic groups, the pp nonwoven fabric(Hydrophilic Spunbond Non-Woven Fabric Factory) has substantially no water absorption properties. Hydrophilic modification or hydrophilic finishing must be carried out to produce a hydrophilic pp nonwoven fabric.

Method for preparing hydrophilic nonwoven fabric

In order to improve the hydrophilicity of pp nonwoven fabrics(Hydrophilic Nonwoven Fabric Supplier), it is usually by improving the surface wetting properties, mainly physical modification and chemical modification.

Chemical modification mainly changes the molecular structure of PP and adds a hydrophilic group to the macromolecular chain to change its hygroscopicity. There are mainly methods such as copolymerization, grafting, crosslinking, and chlorination.

Physical modification primarily alters the higher structure of the molecule to improve the hydrophilic effect, primarily by blend modification (ie, prior to spinning) and surface modification (ie, after spinning).
