聚丙烯短纤维的生产工艺大部分采用多孔、低速、连续化工艺，即短纺工艺。聚丙烯短纤维与棉花混纺，可做成丙棉细布、床单，即纤维与黏胶混纺可做毛毯，聚丙烯纯纺和混纺毛线，聚丙烯毛毯、地毯，聚丙烯棉絮烟用滤咀。卫生产品用纤维的粗细为1.5-2.5dtex，而地上织物用纤维的粗细为5-10 dtex。纤维长短为1.5-200.0 mm，取决于纤维的用途。用作混凝土的短纤维长度为1.5-200.0 mm，用作尿布的长度一般为40.0 mm，用作地上织物的长度为60.0 mm。
The production process of polypropylene staple fibers is mostly porous, low-speed and continuous, that is, short spinning process. Polypropylene staple fiber and cotton blend, can be made into polypropylene cotton fine cloth, bed sheet, that is, fiber and viscose blend can be made into blankets, polypropylene pure and blended wool, polypropylene blanket, carpet, polypropylene cotton flocculent cigarette filter tip. The thickness of fibers for sanitary products is 1.5-2.5 dtex, while that for ground fabrics is 5-10 dtex. The length of the fibers is 1.5-200.0 mm, depending on the use of the fibers. The length of short fibers used as concrete is 1.5-200.0 mm, the length of diapers is 40.0 mm, and the length of ground fabrics is 60.0 mm.
纺黏无纺布，亦称长丝无纺布，是聚丙烯原料熔融后经挤压纺丝、拉伸、铺网、粘合成形制成。它具有流程短、成本低、生产率高、产品性能优良、用途广泛等特点。聚丙烯无纺布广泛应用于生产、生活的各个领域(如一次性医疗卫生用品、一次防污服、农业用布、家具用布、制鞋业的衬里等)。
Spunbonded nonwovens, also known as filament nonwovens, are formed by extrusion spinning, drawing, netting and bonding of polypropylene raw materials after melting. It has the characteristics of short process, low cost, high productivity, excellent product performance and wide use. Polypropylene non-woven fabric is widely used in various fields of production and life (such as disposable medical and health supplies, primary anti-fouling clothing, agricultural cloth, furniture cloth, lining of shoemaking industry, etc.).
