AI Technical Summary

Problems solved by technology

The surface layer of existing pp spunbonded non-woven sanitary products is mostly perforated film, hot-air non-woven fabric and pure cotton spunlace non-woven fabric, which have the following problems: such as poor air permeability of perforated film non-woven fabric; The dryness of the cloth is good, but the biocompatibility is poor, and the burr feeling is strong; while the dryness of the pure cotton spunlace non-woven fabric is poor, and it is easy to produce a feeling of wet adhesion
This patent solves the technical problem of flame retardancy of spunbonded non-woven fabrics, but still does not solve the technical problems of moisture absorption and breathability

Abstract

The invention discloses a seaweed-modified PP spunbonded nonwoven fabric, which contains 0.1-2% of alginate. The moisture regain of the seaweed modified pp spunbonded nonwoven fabric is 0.2-3.5%, and the antibacterial rate is ≥98%; the seaweed modified pp spunbonded nonwoven fabric prepared by the present invention has added modified alginic acid, and has hydroxyl, amide Hydrophilic functional groups such as radicals and hydrophobic functional groups such as branched alkyl groups can give protons and accept protons after being spun into non-woven fabrics with pp, so that when the surface of the non-woven fabric encounters liquid, it can significantly reduce the liquid Surface tension; In addition, there are a lot of gaps in the dense interpenetrating grid structure formed by modified alginic acid, forming a sponge-like structure with good hygroscopicity; and the water absorption speed is fast, and the surface remains dry after absorbing water, and can absorb Its mass is many times more than water, and it has good hydrophilic performance.

Description

technical field [0001] The invention relates to the technical field of spun-bonded non-woven fabrics, in particular to a seaweed-modified PP spun-bonded non-woven fabric. Background technique [0002] PP spunbonded nonwoven fabric is a breathable but not water-permeable fiber structure formed by using polypropylene raw materials and bonding them into a net through high-temperature spinning and carding. It is mainly used for disposable medical and sanitary products, disposable antifouling clothing, agricultural cloth, Cloth for furniture and lining materials, etc. The surface layer of existing pp spunbonded non-woven sanitary products is mostly perforated film, hot-air non-woven fabric and pure cotton spunlace non-woven fabric, which have the following problems: such as poor air permeability of perforated film non-woven fabric; The dryness of the cloth is good, but the biocompatibility is poor, and the burr feeling is strong; while the dryness of the pure cotton spunlace non...
