Abstract

The present invention relates to a polyolefin nonwoven fabric longitudinal penetration multiple times hydrophilic agent, characterized in that: the hydrophilic agent is composed of the following components: a. Gemini sulfonic acid group anion / nonionic wetting and penetrating agent 30-40 %, b. Hydroxyphosphate betaine amphoteric surfactant 5-15%, c. Separation multi-subtype non-ionic surfactant 15-25%, d. Weakly hydrophilic gemini-type non-ionic surfactant 30-40% %. The combination of the fast wetting and penetrating type of hydrophilic agent of the present invention and the weakly hydrophilic surfactant can effectively reduce the water-liquid wetted area and side leakage on the surface of the nonwoven fabric to be finished under the premise of meeting the requirements of water permeability. chance, improving the comfort of using absorbent disposable hygiene products.

Description

technical field [0001] The invention relates to an auxiliary agent used in the processing of absorbent disposable sanitary products, in particular to a polyolefin nonwoven fabric longitudinally penetrating multiple times hydrophilic agent. Background technique [0002] Currently commonly used polyolefin nonwovens include polypropylene and polyethylene / polypropylene composite fiber nonwovens, which are widely used in medical and health fields, clothing cloths, and wiping materials due to their excellent performance and low price. Due to the non-polar structure of this type of fiber, the nonwoven fabric made of this material has basically no hygroscopic and water absorption functions, which limits its application in the above fields, so it must be hydrophilically modified. [0003] The non-woven fabrics used in the field of absorbent disposable hygiene products are currently mainly modified by surface hydrophilic finishing, which is about to be made into a certain concentratio...
