Problems solved by technology

For example, in the current diapers, the traditional surface layer has poor hydrophilicity for many times, or the urine seeps slowly, resulting in long-term retention of urine between the human skin and the surface layer of the diaper, which is heavy in humidity, poor in comfort, and damp. Bacteria are easy to breed in the environment; the skin of women’s sensitive parts during menstruation is most vulnerable to damage or infection. According to the survey, 73% of women will feel local skin itching and burning pain during menstruation. This is mainly because the existing sanitary napkin products are made of non-woven Made of cloth, the surface material of sanitary napkins is rough and inferior, and the performance is poor

Abstract

The invention relates to a non-woven fabric, in particular to a dry and clean high-adsorption hot-air non-woven fabric. Raw materials for the dry and clean high-adsorption hot-air non-woven fabric include, by weight, 40-50 parts of ES (ethylene-propylene side by side) composite fibers, 20-40 parts of super-absorbent fibers, 10-30 parts of silk fibers and 10-20 parts of chitin fibers. The ES composite fibers are silver-doped PE / PP (polyethylene / polypropylene) sheath-core composite fibers and / or silver-doped PE / PET (polyethylene terephthalate) core-sheath composite fibers; spinning oil is coatedon the surfaces of the ES composite fibers and comprises 10-15 wt% of antistatic agents, 25-35 wt% of aromatic plant extract, 0.05-0.1 wt% of metal chelating agents and the balance deionized water. The dry and clean high-adsorption hot-air non-woven fabric has the advantages that water can be effectively absorbed by the dry and clean high-adsorption hot-air non-woven fabric, and the dry and cleanhigh-adsorption hot-air non-woven fabric is high in liquid penetration speed, low in back bleeding, good in softness and comfort and free of irritation on skin and is antibacterial.

Description

technical field [0001] The invention relates to a nonwoven fabric, and more particularly relates to a dry, high-adsorption hot-air nonwoven fabric. Background technique [0002] Hot-air non-woven fabric belongs to one of hot-air bonded (hot-rolled, hot-air) non-woven fabrics. After the fibers are carded, the hot air on the drying equipment is used to penetrate the fiber web to make it bonded by heating. of non-woven fabrics. Hot rolling bonding refers to a thermal bonding method in which a pair of hot rollers are used to heat the fiber web and a certain pressure is applied at the same time; hot air bonding refers to the use of hot air to penetrate the fiber web on the drying equipment to heat and melt it to form a bond. combined production methods. [0003] ES fiber is an ideal heat-bonding fiber. ES fiber is the abbreviation of "Ethylene-Propylene Side BySide" in English, that is, a low melting point bicomponent composite fiber. It is composed of two chips with different ...
