开发羊绒细号纱针织产品的研究

为了开发细号羊绒纱针织产品，选用不同线密度的羊绒纱、棉纱、Ｔ／Ｃ混纺纱、涤纶低弹丝和丙纶长丝在单面圆形纬编机上进行了编织试验。作了上机对比及交织试验，测出了各纱线的强度、最大伸长率、对成圈机件的摩擦系数、最大喂纱张力、最小最大线圈长度。最大允许喂纱张力及最大最小线圈长度之差可综合评价线线的可编织性。羊绒纱的摩擦系数普遍较大，而其强度还不及棉纱的一半，最大允许喂纱张力仅为涤纶纱的１／５。羊绒纱的最小线圈长度为２．８～３．５ｍｍ，最大线圈长度能够测出，说明羊绒纱的可编织性较差。试验表明，用单面纬编机生产以羊绒为正面添纱、交织纱在织物反面的添纱组织，具有羊绒效果且服用性能良好。为了顺利地进行生产，对编织工艺、成圈过程中各阶段纱线的受力情况、上机工艺参数、机器选择和染色工艺等作了分析。

Torsional Models of Two - ply Yarn

In this paper,the vector equation of a generaliseddoubly wound helix was derived.Treloar's pliedyarn geometry could be obtained as a special case ofthe generalised doubly wound helix.The shortest fi-bre length around the surface of a helical tube(formed by fibre helices)was determined by apply-ing variational principles.The fibre length as calcu-lated by using Treloar's geometry was compared in-directly with the shortest possible fibre length at dif-ferent levels of yarn deformation when some of Tre-loar's rigid geometrical constraints were relaxed.Anew idea based on non-concentric circles was intro-duced to approximate the fibre helix movement in atwo-ply yarn.A torsional model of two-ply yarnwas developed and the theoretical predictions werecompared with some preliminary experimental re-sults.
