Hydrophilic Non-woven Fabric is an environmentally-friendly textile fabric, may know not many people, but to give a few of the products it produced you know, we often see adults or infants with urine is not wet, home life must be dishcloth, women's sanitary napkins and so on, are made from it, hydrophilic non-woven Fabric has a strong liquid adsorption, harmless to the human body, Convenient and practical!
hydrophilic Non-woven Fabric: Mainly used in the production of medical and health materials to achieve better feel and do not scratch the skin. Like sanitary napkins, Hydrophillic Nonwoven sanitary pads is the use of hydrophilic Non-woven fabric hydrophilic function.
Hydrophilic Non-woven Fabric is in the production process of non-woven fabric to add hydrophilic agent, or in the process of fiber production with hydrophilic agent on the fiber, Hydrophillic Nonwoven and then production of Non-woven fabric.
Hydrophilic Non-woven fabric is characterized by: the non-woven fabric has a certain capacity to absorb moisture. In the application, such as medical supplies, health care supplies, hydrophilic non-woven fabric hydrophilic effect, can make the liquid fast conduction to the absorption core, hydrophilic non-woven fabric itself absorption performance is not good, the general moisture regain rate in about 0.4%.
Hydrophilic Non-woven fabric is in non-woven production process to add hydrophilic agent, or in the process of fiber production to add hydrophilic agent on the fiber, and then produced Non-woven cloth is the legendary hydrophilic Non-woven.
Why do you want to add hydrophilic agent? This is because the fiber or non-woven fabric is a polymer, the hydrophilic group itself is less, or no hydrophilic group, can not achieve the application of Non-woven fabrics required hydrophilic Energy, so add hydrophilic agent, increase its hydrophilic group.
Then someone would ask what is a hydrophilic agent? The surface tension can be rapidly reduced. Many are long chain organic compounds, the molecule in the presence of hydrophilic groups and lipophilic groups.
1. Types of surfactants: Ionic (anion, cation and amphoteric) surfactants and nonionic surfactants.
2, Nonionic surfactant: poly Sls ester (tween Tween)-20,-40, 60, 80, dehydration Sls mono lauric acid ester (Sipan span)-20, 40, 60, 80, Polyoxyethylene lauryl ether (MYRJ)-45, 52, 30, 35, Emulsifier op ( Alkyl phenol polyoxyethylene ether condensate), Milk lark A (polyoxyethylene fatty alcohol ether), Sismago-1000 (polyoxyethylene and Whale wax alcohol Plus), Pu Ronnie (polyoxyethylene propylene glycol condensation), Hydrophillic Nonwoven single oleic acid glycerin and glycerin monostearate, etc.
3, anionic surfactant: Soft soap (potassium soap), hard soap (sodium soap), single stearic acid aluminum, calcium stearate, oleic acid triethanolamine, sodium lauryl sulfate, Hydrophillic Nonwoven whale hard alcohol sodium sulfate, sulfated castor oil, sodium butadiene acid dioctyl ester sulfonate.
4, cationic surfactant: Jie, new jie, chlorinated benzene methyl hydrocarbon ammonium, chlorinated benzene Milo, brominated 16-alkanes, and so on, Hydrophillic Nonwoven almost all disinfection and sterilization agent.
5, Amphoteric surfactant: less;
This hydrophilic Non-woven fabric is made from ordinary polypropylene spunbonded Non-woven fabric by hydrophilic water treatment, and has good hydrophilicity and permeability. Mainly used in health products, such as urine is not wet, paper diapers, sanitary towel surface layer, can quickly penetrate to maintain dry and comfortable. It can be said that the application in our life is very common!
