Abstract

The invention discloses a reusable non-woven fabric composite fabric and a processing technology. The reusable non-woven fabric composite fabric comprises an outer layer fabric and an inner layer fabric, the outer layer fabric comprises two layers of non-woven fabrics, the non-woven fabrics of the outer layer fabric comprise 85-90 parts of polylactide, 5-10 parts of citric acid modified polypropylene ether and 2-6 parts of aramid fiber, the surface of at least one layer of non-woven fabric is coated with an anhydrous adhesive, an excipient adheres to the surface of the non-woven fabric, the excipient is clamped between the two layers of non-woven fabric by attaching the two layers of non-woven fabric, and drying is conducted. The inner layer fabric comprises a non-woven fabric layer and a polyethylene resin film layer, 70-84 parts by weight of polyethylene resin, 10-15 parts by weight of kapok fiber and 0.5-1 part by weight of a lubricant are added into a stirrer to be stirred and dispersed uniformly, then 1-3 parts by weight of a digesting agent and 5-10 parts by weight of a cross-linking agent are added to prepare a polyethylene resin film, the outer surface of one end of the non-woven fabric is coated with the polyethylene resin film layer to obtain the inner-layer fabric.

Description

technical field [0001] The invention relates to the field of protective clothing fabrics, in particular to a reusable non-woven composite fabric and a processing technology. Background technique [0002] Medical protective clothing is the working attire of medical staff, which isolates germs, harmful ultrafine dust, acidic solutions, and saline solutions to keep the environment clean. Using PP (polypropylene, accounting for 62% of the total) non-woven material, covered with a special breathable film for protective clothing, strong air permeability, anti-static; better anti-permeability, resistant to various organic solvents, acid and alkali corrosion At the same time, it has high impact resistance. Strong mechanical properties, soft and comfortable texture. Non-combustible, non-toxic, non-irritating, and harmless to the skin. Medical protective clothing is used by medical staff to protect protective equipment that blocks foreign bacteria, dust, etc. When in contact with ...
