Problems solved by technology

[0002] Due to the processing characteristics and product cost of non-woven fabrics, synthetic fibers have been mostly used for a long time, and polyester and polypropylene fibers are the most. In some cases, synthetic fibers and natural fibers are used to mix fibers, resulting in poor hydrophilicity of the product

Abstract

The invention provides a preparation method of a hydrophilic finishing agent for a non-woven fabric. The finishing agent is prepared from the following raw materials in parts by weight: allyl polyethylene glycol, sodium di(2-ethylhexyl) sulfosuccinate, tetramethylhexamethylenediamine, glyceryl stearate citrate, ethylene glycol monostearate, polydienedimethylammonium chloride, polyvinylpyrrolidone,3-6 parts of sodium carboxymethylcellulose, polyvinyl alcohol, a surfactant, a dispersing agent, and an organic solvent. A test result shows that the water drop diffusion time of a polyester fabric finished by the hydrophilic finishing agent is as short as 0.2s, and the softness score of the polyester fabric reaches 4-5, so that the finishing agent prepared by the method has good hydrophilicity and softness, and has good application prospects in the field of textiles.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of a nonwoven fabric hydrophilic finishing agent. Background technique [0002] Due to processing characteristics and product cost, nonwoven fabrics have been mostly made of synthetic fibers for a long time, with polyester and polypropylene being the most. In some cases, mixed fibers of synthetic fibers and natural fibers are used, resulting in poor hydrophilicity of the product. [0003] Non-woven fabrics have high requirements for hydrophilic properties, whether they are medical and sanitary materials or materials for wearing and wiping. In the field of medical and health care, disinfectant wipes, wound dressings, hemostatic patches, bandages, gauze balls, ointment cloths, absorbent pads, etc. are all required to have good blood and liquid absorption properties. Absorbent disposable materials, such as baby diapers, women's sanitary napkins, an...
