What is hydrophilic non woven fabric? Hydrophilic non woven fabric is opposite to water repellent non woven fabric. Hydrophilic non woven fabric is to add hydrophilic agent in the production process of non woven fabric, or add hydrophilic agent in the fiber production process, and then produce the legendary hydrophilic non woven fabric.
Spunbonded hydrophilic bottom non woven fabric is made of common polypropylene spunbonded non woven fabric by hydrophilic treatment, which has good hydrophilicity and permeability;It is a kind of environment-friendly textile with air permeability, light weight and strong water absorption; It is mainly used for sanitary products, such as diapers, diapers, sanitary napkins, etc., which can quickly penetrate and keep dry and comfortable. It can be said that it is very common in our life!
This is because the fibers or non woven fabrics in the hydrophilic non woven fabric are high molecular polymers with few or no hydrophilic groups, which cannot achieve the hydrophilic properties required for the application of non woven fabrics. Therefore, a hydrophilic agent is added to increase its hydrophilic group.
Hydrophilic agent in hydrophilic non woven fabric can rapidly reduce the surface tension. Most of them are long-chain organic compounds, including hydrophilic groups and lipophilic groups.
1.Type of surfactant: surfactant and non-ionic surfactant.
2.Non ionic surfactant: polysorbate (Tween) -20- 40.60.80. Sorbitol monolaurate (span) -18.104.22.168 Polyoxyethylene lauryl alcohol ether (myrj) -22.214.171.124 Emulsifier OP (nonalkylphenol polyoxyethylene ether condensate).
3.Anionic surfactants: soft soap (potassium soap), hard soap (sodium soap), aluminum monostearate, calcium stearate, triethanolamine oleate, sodium lauryl sulfate, sodium dodecanol sulfate, castor oil sulfate, sodium dioctyl succinate sulfonate, etc.
4.Cationic surfactants: geramine, Bromogeramine, benzoic chloride, benmelol chloride, cetyltrimethyl bromide, etc.
5.Amphoteric surfactant: less; It is also a disinfectant and antiseptic.
In fact, hydraulic spunbond non woven fabric is very common in life. With the development of science and technology, its application will be more and more extensive. In addition, its environmentally friendly materials and low prices will be the general trend of the commodity industry in the future.
