Abstract

The invention discloses a hydrophilic melt-blown non-woven fabric. The hydrophilic melt-blown non-woven fabric comprises, by weight, 40-60 parts of polypropylene chips, 15-20 parts of polybutylene terephthalate chips, 3-5 parts of chlorinated biphenyl, 3-5 parts of molybdenum disulfide and 0.5-1 part of nanometer Au36 (SCH2CH3) 24 clusters. A technology for processing the hydrophilic melt-blown non-woven fabric includes steps of (1), preparing modified resin chips; (2), carrying out melt-blowing on the resin chips; (3), preparing a non-woven fabric; (4), treating the non-woven fabric; (5), carrying out drying treatment. The hydrophilic melt-blown non-woven fabric has the advantages that polypropylene and polybutylene terephthalate are used as matrixes, the chlorinated biphenyl and the molybdenum disulfide are added into the matrixes to modify the matrixes, accordingly, the flowability of melt can be enhanced during melt-blowing processing, and the hydrophilic melt-blown non-woven fabric which is a modified melt-blown non-woven fabric with small pore diameters and high filter precision can be prepared; surface hydrophilic treatment is carried out on the non-woven fabric, which is obtained by means of melt-blowing, by the aid of compound surfactants, hydrophilic treatment parameters are adjusted, accordingly, the wettability of the surfaces of the non-woven fabric can be effectively changed, and the hydrophilicity of the non-woven fabric can be enhanced.

Description

technical field [0001] The invention belongs to the field of non-woven fabrics, and in particular relates to a hydrophilic melt-blown non-woven fabric. Background technique [0002] Melt-blown nonwovens were first developed by the U.S. Navy in 1954. Through the air jet method, the fiber diameter can be controlled below 5 μm. Because the fiber diameter is small and soft, it is made into a nonwoven fabric. With the continuous development and improvement of technology, the application of melt-blown non-woven materials in filtration, waterproof, adsorption, anti-bacteria, warmth, medical and health care has increased. In recent years, new materials, new processes and new products of melt-blown nonwovens have emerged continuously, and the application fields have continued to expand. [0003] Melt-blown non-woven fabrics are low in production cost and have the characteristics of softness and fluffiness, so they can be used as the base material of wet wipes to ensure the softness...
