| 聚丙烯长纤维可分为普通长纤维和细旦长纤维(单丝纤度≤2.2 dtex，可用于生产服装与装饰和部分产业用长丝制品。聚丙烯细旦长纤维光泽好、手感柔软、悬垂性良好、密度小，适用于针织行业，与棉、黏胶丝、真丝、氨纶等交织成棉盖丙、丝盖丙等产品时，是制作高档运动服、T恤等的理想材料。 Polypropylene long fiber can be divided into ordinary long fiber and fine denier long fiber (monofilament size ≤ 2.2 dtex), which can be used to produce clothing, decoration and some industrial filament products. Polypropylene fine denier long fiber has good luster, soft handle, good drapability and small density. It is suitable for knitting industry. When it interweaves with cotton, viscose silk, silk, spandex and other products into cotton cap C, silk cap C and other products, it is an ideal material for making high-grade sportswear, T-shirt and other products. 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。 Most of the production processes of polypropylene staple fiber are porous, low-speed and continuous, that is, short spinning process. Polypropylene short fiber and cotton blended can be made into polypropylene cotton fine cloth and bed sheet, that is, fiber and viscose blended can be used as blanket, polypropylene pure and blended wool, polypropylene blanket, carpet, polypropylene cotton cigarette filter nozzle. The thickness of the fiber for sanitary products is 1.5-2.5 dtex, while the thickness of the fiber for ground fabric is 5-10 dtex. The length of the fiber is 1.5-200.0 mm, depending on the purpose of the fiber. The length of short fiber used as concrete is 1.5-200.0mm, the length used as diaper is generally 40.0mm, and the length used as ground fabric is 60.0mm. 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)。 Spunbond nonwovens, also known as filament nonwovens, are made by extrusion spinning, stretching, netting and bonding after melting of polypropylene raw materials. 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 products, primary anti pollution clothing, agricultural cloth, furniture cloth, lining of footwear industry, etc.). |
