What is a hydrophilic non-woven fabric? Hydrophilic non-woven fabric is an environmentally friendly textile fabrics. It is opposite to the water repellent nonwoven fabric. The hydrophilic nonwoven fabric is obtained by adding a hydrophilic agent to the production process of the nonwoven fabric, or adding the hydrophilic agent to the fiber in the course of the fiber production, and then producing the nonwoven fabric which is the legendary hydrophilic nonwoven fabric La.
May know that many people, but give it a few products you know, we often see the adult or baby with urine is not wet, home life necessary wipes, ladies with sanitary napkins, etc., are Is made of it, hydrophilic non-woven fabric has a strong liquid adsorption, harmless to the human body, convenient and practical!
Why is it necessary to add a hydrophilic agent? This is because the fiber or non-woven fabric is a high molecular polymer, its own hydrophilic groups, or no hydrophilic groups, can not achieve the necessary non-woven applications in the hydrophilic properties , Thereby adding a hydrophilic agent to increase its hydrophilic groups.
Then someone will ask what is a hydrophilic agent? It can make the surface tension drop rapidly. Mostly long chain organic compounds, molecules in the presence of hydrophilic groups and lipophilic groups. The purpose of the addition of the hydrophilic agent is that the fiber or nonwoven fabric is a high molecular polymer having less hydrophilic groups or no hydrophilic groups and can not achieve the desired hydrophilic properties in nonwovens applications and thus Hydrophilic agent.
1, the types of surfactants: ionic (anionic, cationic and amphoteric) surfactants and nonionic surfactants.
2, nonionic surfactants: polysorbate (Tween Tween) -20, -40, 60, 80, sorbitan monolaurate (Span) -20,40,60,80, poly Oxygenated lauryl alcohol (sold by Myrj) -45,52,30,35, emulsifier OP (nonylphenol polyoxyethylene ether condensate), milk Braun A (polyoxyethylene fatty alcohol ether), West (Polyoxyethylene and cetyl alcohol adduct), Pu Luluo Ni (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, whale hard sodium sulfate, sulfated Castor oil, sodium dioctyl succinate, and the like.
4, cationic surfactants: Jie Er destroy, benzalkonium bromide, benzalkonium chloride, chlorpheniramine chloride, bromide hexadecane and so on; almost all disinfectant.
5, amphoteric surfactants: less; also for the disinfection of preservatives.
This hydrophilic non-woven fabric is made of ordinary polypropylene spunbond non-woven fabric by hydrophilic processing, with good hydrophilicity and permeability. Mainly used in health products, such as urine is not wet, diapers, sanitary napkins surface layer, can quickly penetrate to keep dry and comfortable. Can be said that in our lives, but it is very common!
