聚丙烯纤维发展简史
聚丙烯纤维发展简史
Brief History of Polypropylene Fiber Development
早期，丙烯聚合只能得到低聚合度的纸化产物，属于非结晶性化合物，无实用价值。1954年，Ziegler和Natta发明了Ziergler-Natta催化剂并制成结晶性聚丙烯，具有较高的立构规整性，称为全同立构聚丙烯或等规聚丙烯。这一研究成果在聚合领域中开拓了新的方向，给聚丙烯大规模的工业化生产和在塑料制品以及纤维生产等方面的广泛应用奠定了基础。
In the early stage, propylene polymerization could only produce paper products with low degree of polymerization, which belonged to non-crystalline compounds and had no practical value. In 1954, Ziegler and Natta invented the Ziergler-Natta catalyst and made crystalline polypropylene, which has

This research result has opened up a new direction in the field of polymerization, and laid a foundation for large-scale industrial production of polypropylene and its wide application in plastic products and fiber production.
1957年，由意大利的Montecatini公司首先实现了聚丙烯的工业化生产。1958-1960年，该公司又将聚丙烯用于纤维生产，开发商品名为Meraklon的聚丙烯纤维，以后美国和加拿大也相继开始生产。
In 1957, the Italian company Montecatini first realized the industrial production of polypropylene. From 1958 to 1960, the company used polypropylene for fibre production. The product was called Meraklon polypropylene fibre. Later, the United States and Canada began to produce polypropylene fibers.
1964年后，又开发了捆扎用的聚丙烯膜裂纤维，并由薄膜原纤化制成纺织用纤维及地毯用纱等产品。
After 1964, polypropylene film-splitting fibers for bundling were developed, and textile fibers and carpet yarns were made from film fibrillation.
20世纪70年代，短程纺工艺与设备改进了聚丙烯纤维生产工艺。同期，膨体连续长丝开始用于地毯行业。目前，全球90%的地毯底布和25%的地毯面纱由聚丙烯纤维制得。
In the 1970s, the short-haul spinning process and equipment improved the production process of polypropylene fibers. In the same period, expanded continuous filament began to be used in carpet industry. At present, 90% of the carpet undercloth and 25% of the carpet veil in the world are made of polypropylene fibers.
1980年以后，随着聚丙烯和制造聚丙烯纤维新技术的发展，特别是茂金属催化剂的发明使得聚丙烯树脂的品质得到了明显的改善。由于提高了其立构规整性(等规度可达99.5%)，从而大大提高了聚丙烯纤维的内在质量。80年代中期，聚丙烯细特纤维替代了部分棉纤维，用于纺织面料及非织造布。加上一步法BCF纺丝机、空气变形机与复合纺丝机的发展以及非织造布的出现和迅速发展，聚丙烯纤维在装饰和产业用方面的用途进一步拓宽。另外，世界各国对聚丙烯纤维的研究与开发也相当活跃，差别化纤维生产技术的普及和完善，大大扩大了聚丙烯纤维的应用领域。
Since 1980, with the development of new technologies for polypropylene and polypropylene fibers, especially the invention of metallocene catalysts, the quality of polypropylene resin has been significantly improved. The intrinsic quality of polypropylene fibers is greatly improved by improving its texture regularity (isotacticity can reach 99.5%). In the mid-1980s, polypropylene fine fibers replaced some cotton fibers for textile fabrics and nonwovens. With the development of one-step BCF spinning machine, air texturing machine and composite spinning machine as well as the emergence and rapid development of nonwovens, the application of polypropylene fibers in decoration and industry has been further broadened. In addition, the research and development of polypropylene fibers are also very active all over the world. The popularization and perfection of differential fiber production technology has greatly expanded the application field of polypropylene fibers.
