Abstract
The invention relates to an environment-friendly multi-time hydrophilic finishing agent for a polyolefin non-woven fabric. The environment-friendly multi-time hydrophilic finishing agent is characterized by containing (A) 25 to 45 percent of phosphate anionic / nonionic wetting penetrant, (B) 10 to 30 percent of gemini nonionic surfactant, (C) 15 to 25 percent of hydroxyl phosphate betaine ampholytic surfactant and (D) 20 to 40 percent of polymer nonionic surfactant. The environment-friendly multi-time hydrophilic finishing agent disclosed by the invention is prepared from a vegetable oil derivative serving a hydrophobic group main raw material, is simpler in preparation process, high in utilization rate of atoms, free from of toxic or harmful intermediate and little in adverse influence on environment, and has no stimulation on the skin in the use process; after being discarded, the environment-friendly multi-time hydrophilic finishing agent is easily biologically degraded under natural conditions and has small pollution to the environment, so the environment-friendly multi-time hydrophilic finishing agent is an environment-friendly hydrophilic agent; due to a synergistic effect of anionic, ampholytic, gemini and polymer type surfactants, the finished polyolefin non-woven fabric is enabled to have better instantaneity and more excellent multi-time water permeability.
Description
technical field [0001] The invention relates to an auxiliary agent used in the processing of disposable sanitary products, in particular to an environment-friendly polyolefin nonwoven fabric multiple times hydrophilic finishing agent. Background technique [0002] The invention and wide application of disposable medical, health care and sanitary products have brought huge benefits to human life quality and social development, and also brought people a new way of life. Absorbent disposable sanitary products, including feminine hygiene products, baby diapers, adult incontinence products, wet wipes, pet pads and other sanitary products, have continued to grow in my country's market size in recent years, from 40 billion yuan in 2010 to 621 in 2013 billion, with an average annual growth rate greater than 13%. [0003] Currently commonly used polyolefin nonwovens include polypropylene and polyethylene / polypropylene composite fiber nonwovens, which are widely used in medical and he...
