使用分段经轴改善经纱张力不匀

Improvement of uneven warp tension distribution using a sectional warp beam device

织物宽度方向的经纱张力不匀将会造成织造困难并导致织物质量下降。目前,纱线长度补偿使经纱张力均匀化从技术上讲是不可能实现的。德国亚琛工业大学纺织技术研究所(ITA),正在对一个有望减少经纱张力不匀的方式进行可行性和影响的研究。分段经轴系统可用于提高织物质量和制造过程的稳定性,进而提高织造效率,普通经轴被10个很窄的、分别独立控制的分段织轴所取代。

Inhomogeneous warp tension across the fabric width leads to weaving process difficulties and results in poor fabric quality. At present, yarn length compensation and thereby homogenization of warp tension is techni- cally not possible. At Institut far Textiltechnik der RWTH Aachen University （ITA）, Aachen/Germany, the feasibility of a promising attempt to reduce warp tension inhomogenity and its effects is being researched. A system of sectional warp beams has been developed to increase fabric quality, process stability and there- by weaving productivity. The common warp beam is replaced by 10 narrow, individually controlled sectional warp beams.
