As a Sanitary Napkin Raw Material Nonwoven Fabric Supplier, the classification of the properties of the hydrophilic nonwoven fabric is described below.
Classified according to the hydrophilicity and hydrophobicity of the non-woven fabric:
Hydrophobic Non-woven Fabric: Cannot be used on the surface of sanitary napkins and can be used on the side of sanitary napkins (ie wings).
Hydrophilic Nonwovens: can be divided into hydrophilic, multiple hydrophilic.
The hydrophilicity of the non-woven fabric is mainly determined by the oil agent of the fiber surface. According to the oil agent, it can be divided into a single hydrophilic non-woven fabric (ie, one hydrophilic), a multi-hydrophilic non-woven fabric (ie, multiple hydrophilic), Weak hydrophilic nonwoven fabric.
Single hydrophilic non-woven fabric: For the penetration of liquid, the first penetration speed is faster, and the subsequent liquid penetration speed is gradually slowed down.
Multi-hydrophilic non-woven fabric: It is widely used in the processing of sanitary napkins, and its product has better water absorption performance and strong liquid penetration ability. The penetration time of the second, even the third, liquid is also very short.
Weakly hydrophilic non-woven fabric: It is also a concept that has emerged in recent years. Its product is characterized by a relatively good liquid vertical infiltration effect, a horizontal spread of the surface, and a diffusion into the lower layer (drainage layer). The lower layer material), the amount of reverse osmosis is relatively low, and the surface is relatively dry. After aspiration, it appears to be relatively clean due to its small surface area.
There is a huge space for the development of hydrophilic non-woven fabrics. The non-woven fabrics on women's sanitary napkins and baby diapers are required to have hydrophilic properties, which means that water needs to be easily penetrated through the non-woven fabric. The amount is huge.
