what is non woven polypropylene fabric
Polypropylene fibers are synthetic fibers spun from isotactic polypropylene obtained by the polymerization of propylene. The trade name is polypropylene in China.
classification
Polypropylene fiber can be divided into long fiber, short fiber, spunbond non-woven fabrics, meltblown non-woven fabrics.
what is non woven polypropylene fabric
Polypropylene long fibers can be divided into ordinary long fibers and fine denier long fibers (single-filament fineness ≤2.2 dtex, which can be used for the production of garments and decorative and some industrial filament products. Polypropylene fine fibers have good gloss, soft hand feeling, and drape Good quality, low density, suitable for knitting industry, when interlaced with cotton, viscose, silk, spandex, etc. into cotton cap C, silk cap C, etc., it is an ideal material for making high-grade sportswear, T-shirts, etc.

Most of the production process of polypropylene staple fiber uses porous, low-speed, continuous technology, that is, short spinning process. Polypropylene staple fiber and cotton blended, can be made of C cotton fine cloth, sheets, that is, fiber and viscose blends can be made of blankets, polypropylene pure and blended yarns, polypropylene blankets, carpets, polypropylene cotton flue filter. The thickness of the fibers for sanitary products is 1.5-2.5 dtex, and the thickness of the fibers for ground fabrics is 5-10 dtex. The fiber length is 1.5-200.0 mm, depending on the use of the fiber. The short fibers used for concrete have a length of 1.5-200.0 mm, the length of a diaper is generally 40.0 mm, and the length of a ground fabric is 60.0 mm.

Spun-bonded non-woven fabrics, also known as filament nonwoven fabrics, are made from polypropylene melted by extrusion spinning, stretching, plaiting, and bonding. It has the characteristics of short flow, low cost, high productivity, excellent product performance and wide range of uses. Polypropylene non-woven fabrics are widely used in various fields of production and life (such as disposable medical and health products, primary antifouling clothing, agricultural fabrics, furniture fabrics, and linings for the footwear industry).
Melt-blown non-woven fabrics produce fine fibers (up to 0.25 μm). Melt-blown fabrics have a large specific surface area, small pores, and high porosity. Therefore, their filterability, shielding properties, and oil absorption properties are used. Non-woven fabrics produced by other separate processes are difficult to obtain. Melt-blown non-woven fabrics are widely used in medical and health care, thermal insulation materials, filter materials and other fields.
