摘　　要：目前羊毛细化加工工艺和理论仍采用早期的纤维湿态拉伸中的结构模型和理论 ,主张细化拉伸是因肽链大分子由α螺旋到 β折叠的转变所引起。为此提出羊毛纤维“滑移细化”的机理 ,并做了实验验证。The early structural and mechanical models for keratin fibers in moisture-stre tching are still used as the wool slenderzing technology and theory,and it is cl aimed that the slenderizing stretch is resulted from the change of the transform ation from α-heli x configuration to β-fold of macromolecules.The comments on the point of view have been made, the `slippage slenderizing' machanism for wool tops ar e proposed, and the experimental validation has been carried out on the new theory.
