What is a hydrophilic nonwoven fabric? The hydrophilic nonwoven fabric is opposite to the water-repellent nonwoven fabric. The hydrophilic non-woven fabric is a hydrophilic agent added in the production process of the non-woven fabric, or a hydrophilic agent is added to the fiber during the production of the fiber, and then the non-woven fabric produced is a legendary hydrophilic non-woven fabric. La.
Why do you want to add a hydrophilic agent? This is because the fiber or non-woven fabric is a high molecular polymer, which has few hydrophilic groups or no hydrophilic groups, and cannot achieve the hydrophilic properties required for non-woven applications. Thus, a hydrophilic agent is added to increase its hydrophilic group.
Then someone will ask what is a hydrophilic agent? It can cause the surface tension to drop rapidly. Mostly long-chain organic compounds, both hydrophilic groups and lipophilic groups are present in the molecule.
1. Types of surfactants: ionic (anionic, cationic and amphoteric) surfactants and nonionic surfactants.
2, non-ionic surfactant: polysorbate (Tween Tween) -20, -40, 60, 80, sorbitan monolaurate (Span Span) -20, 40, 60, 80, poly Oxyethylene lauryl ether (selling Meyrj) - 45, 52, 30, 35, emulsifier OP (decylphenol polyoxyethylene ether condensate), milk Bailing A (polyoxyethylene fatty alcohol ether), Sisma Co-1000 (polyoxyethylene and cetyl alcohol adduct), Pluronic (polyoxyethylene polypropylene glycol condensate), glycerol monooleate and glyceryl monostearate.
3. Anionic surfactants: soft soap (potassium soap), hard soap (sodium soap), aluminum monostearate, calcium stearate, triethanolamine oleate, sodium lauryl sulfate, sodium cetyl sulfate, sulfated Castor oil, sodium dioctyl sulfonate sulfonate, and the like.
4. Cationic surfactants: Jieerg, Xinjieer, benzalkonium chloride, benzyl merbutin, hexadecane bromide, etc.; almost all disinfectants.
5. Amphoteric surfactants: less; also disinfectant preservatives.
The hydrophilic non-woven fabric is processed by hydrophilic treatment of a common polypropylene spunbonded nonwoven fabric, and has good hydrophilicity and permeability. Mainly used in sanitary products, such as diapers, diapers, sanitary napkins, can penetrate quickly to keep dry and comfortable. It can be said that application in our lives is very common!
