example 1

[0020] A production process of medical spunlace non-woven fabrics. The raw materials are high-density cotton yarn, activated carbon fiber and nano-silver modified slurry. The raw materials are opened, carded into a web, spunlace reinforced, dipped and modified, fruit dyed, and dried. Drying and coiling process to obtain medical spunlace non-woven fabrics. The nano-silver modified slurry is composed of nano-silver powder, modified starch, polyvinyl alcohol, 2-naphthol, potassium hydroxide and deionized water. The specific process steps are as follows:

[0021] (1) Raw material opening: Feed cotton yarn raw materials with a fineness of 1.7dtex and a length of 40mm and activated carbon fiber into the bale opener, manually pick and feed to ensure no impurities, and the raw materials are roughly opened by the horizontal opener through the long conveying curtain Finally, it is sent to the big warehouse through the fan pipeline, and then it is finely opened and loosened by the fine op...

Abstract

The invention discloses a production process of medical spunlace non-woven fabric. High-density cotton yarn, activated carbon fiber and nano-silver modified slurry are adopted as raw materials, and the medical spunlace non-woven fabric is obtained through raw material opening, carding web forming, spunlace reinforcing, dipping modification, fruit dyeing treatment, drying and reeling processing. The nano-silver modified slurry is composed of nano-silver powder, modified starch, polyvinyl alcohol, 2-naphthol, potassium hydroxide and deionized water. The cotton yarn is blended and modified by adopting the activated carbon fiber and the nano-silver modified slurry, the sterilization function of the medical non-woven fabric is achieved, meanwhile, steam does not need to be consumed in the dyeing process, no chemical additive or chemical dye is needed, a fruit dyed product has the characteristics of being purely natural, healthy and comfortable, a layer of natural active pectin can be formedon a dyed cloth cover, unique soft luster is generated, the moisture absorption and air permeability are improved, and good skin friendliness is achieved.

Description

technical field [0001] The invention relates to the technical field of medical nonwoven fabric processing and production, in particular to a production process of medical spunlace nonwoven fabric. Background technique [0002] Spunlaced non-woven fabrics are made of polymer fibers, through the opening, mixing and carding of the fibers to form a fiber web layer of a certain thickness, and then spray multiple high-pressure fine water jets to the fiber web layer, and the water jets pass through the fiber web After the mesh layer is rebounded by the mesh curtain, the fiber mesh layer is interspersed again. The fibers in the fiber web layer are displaced, interspersed, entangled and entangled under the action of high-pressure water jets in different directions, so that the fiber web can be reinforced and have a certain strength. Finally, it is formed after finishing or surface coating. Woven material. [0003] In recent years, the technology of spunlace nonwovens has developed ...
