Abstract

The invention discloses a manufacturing process of ES hydrophilic fiber non-woven fabric. The non-woven fabric adopts PE and PP as raw materials, the manufacturing process is characterized by comprising following steps of screw extrusion spraying, spinning, pre-spinning oiling, curling, in-barrel treatment, post-spinning oiling, two-way stretching, curling, opening, cotton blending, carding, hot rolling or hot air bonding forming, slitting, winding, inspection, non-woven fabric and hydrophilic finishing process, and lastly, the ES hydrophilic fiber nonwoven fabric is obtained, and the hydrophilic nonwoven fabric produced by the process has high hydrophilicity and good hygroscopicity and can be applied to high-level products.

Description

technical field [0001] The invention belongs to the technical field of nonwoven fabrics, and in particular relates to a preparation process of ES hydrophilic fiber nonwoven fabrics. Background technique [0002] ES fiber is a bicomponent fiber with sheath-core structure composed of sheath-polyethylene (PE) and core-polypropylene (PP). It has the remarkable advantages of fluffy, soft, good permeability and good strength. ES fiber non-woven The largest field of cloth application is disposable sanitary products. It is the raw material for the production of the covering layer of the third and fourth generation disposable sanitary products, and it is an ideal material for manufacturing high-end women's sanitary napkins and diapers. With the development of my country's economy, the improvement of people's living standards and the transformation of consumption concepts, the technology of diapers is constantly updated and the market expands. High, traditional non-woven fabrics can n...
