Acetate fiber belongs to a kind of of chemical fibre, but has gloss and feel as the natural real silk, and permeability and moisture pick-up properties are better than common chemical fibre, but has antistatic in addition and advantage natural degradation, and cost of material is also more moderate.Acetate fibre filament alternative natural silk spinning in traditional woven cloths industry is woven as the garment material, underwear, silk scarf of emulation silk etc., and its product processed has human body and dresses good comfort.
Three, summary of the invention: the nonwoven fabric that the object of the present invention is to provide a kind of composite fibre, with and hot rolling processing and fabricating method, this nonwoven fabric adopts acetate fiber and mixes other thermoplasticity chemical fibre and is raw material, processes with the producing technology of non-woven fabrics of hot rolling method, product has good comfort when contacting with human body, can be widely used in the processing of mouth mask, protective clothing, diaper, sanitary napkin, garment material and liner product.
As follows for realizing the technical measures that purpose of the present invention adopts:
Raw material is that acetate fiber adds other staple fibre, respectively by the fiber feeder in proportion quantitatively the proportioning feeding to blending bunker, the working procedure processing of the following hot rolling method of process becomes composite fibre nonwoven cloth successively again: (1) shredding, (2) combing, (3) combing, (4) be overlapped into net, (5) hot calendering bonding, (6) rolling.
Need to prove: acetate fiber shared ratio in raw material is 15-85%; Other chemical fibre need be thermoplastic staple fibre or the staple fibre that contains thermoplastic, can be one or more mixing in polypropylene, polyethylene, the polyester chemical fibre.
Composite fibre nonwoven cloth of the present invention is compared with common fabric hot rolled nonwoven fabrics, density is littler, bulk is better, water imbibition is stronger, also better on flexibility and feel, product has good comfort when contacting with human body, thereby can be widely used in products such as the lining of making mouth mask, protective clothing, diaper, sanitary napkin, clothes and liner.
