摘要(Abstract)：
高强低延涤纶长丝,具有强力高、伸长小、尺寸稳定性好、模量高的特点,主要应用于轮胎、输送带、消防高压水带、电线芯线、缝纫线等。为了满足军工和工业生产的急需,1979年我所完成了涤纶高强长丝的小试工作,并提供了一小批产品。1983年国家科委下达了“7.5克/旦高强涤纶长丝中试研究”的国家科技攻关项目。经过几年来的努力,克服了许多技术难关,终于使用国产原料,生产出65公支高强涤纶长丝,强力≥6.6cN/dT(7.5克/旦),正品率为80％,达到了中试攻关项目的要求。
High tenacity low stretch polyester filament yarn which possess the merits of high strength, low elongation, high modulus and good stability in size are mainly used for tires, conveyer belts, fire hoses, cables and sewing threads etc. Making great efforts to break down many technical barriers for over 2 years, the Shanghai Synthetrc Fiber Research Institate at last using domestic raw materials produces 65 tex polyester filament with a tenacity more than 7.5g/d, the percentage of quality products reaches 80% fulfills the requiremeuts of the pilot project key task item.
