Isotactic polypropylene polypropylene fiber is obtained by the polymerization of propylene as raw materials made of synthetic fibers spun in the country under the trade name of polypropylene.
 

Polypropylene fibers can be divided into long fibers, short fibers, spunbond nonwoven fabric, meltblown nonwoven fabric.
 

- Polypropylene fibers can be divided into ordinary long-fiber and fine denier filaments (monofilament fineness ≤2.2 dtex, can be used in the production of clothing and decorative products and some industrial filament polypropylene fine denier filaments luster, soft drape good, low density, suitable for knitting industry, with cotton, viscose, silk, cotton spandex woven into the cover C, when the wire cover C class products are making upscale sportswear, T-shirts, etc. ideal material.
 

Polypropylene staple fiber production technology and most porous, low-speed, continuous process, that is short spinning process. Polypropylene staple fiber and cotton blend, can be made of cotton muslin prop, sheets, fibers and viscose blend that is to do blankets, polypropylene spinning pure and blended yarn, polypropylene blankets, carpets, polypropylene batt cigarette filter rod.

Sanitary products for the fiber thickness 1.5-2.5dtex, while the ground fabric fiber thickness of 5-10 dtex. Fiber length of 1.5-200.0 mm, depending on the use of fibers. The concrete used as staple length of 1.5-200.0 mm, the length is generally used as a diaper 40.0 mm, a length of fabric is used on the ground 60.0 mm.
 

Spunbond non-woven fabrics, also known as non-woven filament, after the melt-extruded polypropylene material spinning, stretching, layering, bonding molding material. It has a short process, low cost, high productivity, high performance, versatile features. Widely used in the production of non-woven polypropylene, all areas of life (such as disposable medical supplies, a stain clothing, agricultural fabrics, furniture fabrics, footwear linings).
 

Meltblown nonwoven fiber technology to produce very fine (up to 0.25μm), meltblown fabric having a large specific surface area, porosity and pore small, so the filtration, shielding and oil-absorbing properties is used for applications such as other separate process to produce non-woven difficult to have. Meltblown nonwoven fabric widely used in health care, warm materials, filter materials.
