气流阻尼牵伸理论初探

Probing into the Air Damping Drafting Theory

在罗拉—胶圈牵伸机构理论研究的基础上,建立了牵伸区内纤维相对运动的牵伸模型;分析了胶圈控制纤维在原理上的先天不足,指出气流阻尼控制优于胶圈控制;从理论上分析了聚纤纺的合理性,并以逆向思维的方法,创造性地提出气流阻尼牵伸理论的可行性和优越性,为细纱机牵伸机构的创新提供了理论基础。

Based on the theoretical research of the roller-apron drafting mechanism,a drafting matrix of the relative fiber motion is established within the drafting area. Analysis is done to the congenital deficiency of the apron controlled fiber elementarily. Conclusion is made that the air damped control is better than the apron control. Theoretical analysis is done to the justification of the gather fiber spinning and more,the feasibility and the superiority of the air damping drafting theory is introduced with creativeness with the help of the negative thinking, thus laying foundation for the innovation of the drafting mechanism of the spin- ning frame.
