Method For Hydrophilic Modification Of Nonwoven Fabric
Aug 29, 2018

The methods for hydrophilic modification of non-woven fabrics include chemical modification method and physical modification method. Nowadays, physical modification methods are used, and physical modification methods include blend modification method and post-finishing modification method.

The blending modification method is to mix other hydrophilic polymers or surfactants with polypropylene (PP) particles of raw materials for producing non-woven fabric, so that the hydrophilic polymer is filled into the larger spherulites of PP, so that the non-woven fabric The hydrophilic properties of the cloth. 2. The finishing method is to sizing the ordinary non-woven fabric by sizing the ordinary non-woven fabric with a hydrophilic active finishing liquid, an auxiliary agent, and drying, so that the finishing liquid and the auxiliary agent are fixed on the non-woven fabric. The surface allows the ordinary nonwoven fabric to be rendered hydrophilic. For example, an amphoteric surfactant composed of a hydrophilic group and a hydrophobic group is used as a hydrophilic finishing agent for the nonwoven fabric, the surface of the hydrophobic group and the nonwoven fabric are combined, and the hydrophilic agent is outwardly facing, and the continuous hydrophilic group makes contact. The angle is close to zero, giving the nonwoven a hydrophilic property.
