工业化纺粘技术研究的回顾

Review Studies on Industrial Spunbonding Technologies

纺粘法是所有非传统纺织材料成形工艺中生产能力最大的一种加工方法。按不同的工艺技术、树脂类型和产品定量 ,其生产速度的变化范围是 5 0m/min～ 6 0 0m/min ,比传统的加工方式速度快很多倍。考虑到生产效率的因素 ,长丝的生产速度为 2 0 0 0m/min～ 80 0 0m/min ,产品幅宽不小于 3 0m ,最宽达 5 2m。尽管最普遍的定量范围是 17g/m2 ～ 180g/m2 ,而该产品的定量是 10g/m2 ～ 80 0g/m2 。超细纺粘非织造布 (纤维直径小于 10 μm)的纤网均匀度和强力得到进一步的改善。本文阐述了工业化纺粘技术的发展、主要应用和技术含量。

Spunbonding is the most productive of all the nonconventional methods of textile fabric formation. Fabric production rate varies from 50 and 600 m/min, depending on different techniques, resin type and basis weight, it is many times faster than the conventional systems of fabric formatiom. The fabrics are made up to 5.2 m wide and usualy not less than 3.0 m in order to facilitate productivity, with filament production speed from 2 000 to 8 000 m/min. The fabric basis weight ranges from 10～800 g/m 2 although a range of 17～180 g/m 2 is most common. Superfine spunbonded fabrics (less than 10 μm) have already been achieved and web uniformity and strength have been further improved. This presentation will review the development, main applications and state-of-the-art of the industrial spunbonding technology.
