Abstract

The invention relates to a composite non-woven fabric and a preparation method thereof, the composite non-woven fabric comprises a skin-friendly layer, a transition layer, a base layer and a protective layer, the transition layer is located between the skin-friendly layer and the base layer, the skin-friendly layer is bonded and matched with the transition layer, the transition layer is fixedly connected with the base layer, and the base layer is bonded and matched with the protective layer; the base layer is formed by lapping modified polypropylene filaments; the modified polypropylene filament comprises the following raw materials in parts by weight: 80-120 parts of a polypropylene base material; 6-8 parts of dioctadecyl ammonium chloride; 8 to 12 parts of 4-[(heptadecafluorononyl) oxy] sodium benzenesulfonate; 6-8 parts of white mica powder; 2-6 parts of an antibacterial auxiliary agent and 0.5-1.5 parts of a lubricant. The composite non-woven fabric has the advantages that the composite non-woven fabric is not prone to generating static electricity, and therefore the dust adsorption probability is reduced when the composite non-woven fabric serves as a surgical gown fabric.

Description

technical field [0001] The present application relates to the field of high-performance fiber products, in particular to a composite non-woven fabric and a preparation method thereof. Background technique [0002] Non-woven fabrics refer to fabrics made by orienting or randomly arranging textile staple fibers or filaments to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. Non-woven fabrics are moisture-proof, breathable, flexible, light, flame-retardant, non-toxic, tasteless, and inexpensive, and can be used in the medical industry, construction industry, or agriculture. [0003] Non-woven fabrics are easy to generate static electricity during use, which makes non-woven fabrics easy to absorb dust when used as surgical gown fabrics, increasing the risk of surgery. SUMMARY OF THE INVENTION [0004] In order to make the non-woven fabric less likely to generate static electricity, thereby reducing the probability of the non-woven...
