What is non-woven fabric? – Manufacturing Process
It’s called non-woven fabric because it was not made from textile. Normally, fabric materials made from weaving, knitting … that is the combination of warp, weft together.
You can imagine how old weaving was, or look on the fabric we wore, it was composed of two warp threads and one on the other.However, for non-woven fabrics, it is made of PP plastic, heated at high temperature to melt out. We would like to shorten the production process of non-woven fabrics as follows:
1. Put the PP plastic material in the hot-rolled basin at a high temperature and in a closed production process.
2. Plastic pellets after melting, are extruded through a mesh system with thousands of tiny holes, like hairs, to form a filament yarn.
3. Then the heat-treated melts the fibers together and passes through a hot rolled into a flat film.
4. This flat film is rolled by a mold/shaft are engraved some small square that will cause the non-woven fabric surface after the finished product to appear like to be made of textile and we thought it was a warp and weft together (there is a pattern that does not carve these squares, so the surface is smooth as cloth used as medical masks).
Features and applications of non-woven fabric
Waterproof, not affected by microorganisms, fungus, bacteria and washable and used many times, especially decomposition, so called environmentally friendly.
Non-woven fabrics come in a variety of different colors and quantitative.
Currently, this material is very popular in the world and used as shopping bags, packaging, advertising bags, sofa cover, vest cover and so on.And this is a substitute for plastic bag that is dangerous to the environment.
Non-woven fabric is applied to create a wide range of products
Can be printed on the fabric surface, or combine to film mold to create multi color bag products, many images according to diverse needs of users.
