摘要: 棉精梳机在高速梳理时,锡林梳理会造成纤维损伤和断裂,这影响了精梳梳理质量。因此,本文针对此棉纤维的断裂损伤现象,建立在棉纤维不断裂受损条件下的理论车速模型,并计算了棉精梳机的最大理论车速值,即“柔性精梳值”。该理论车速模型考虑了梳理过程中单纤维的平均梳理力和棉纤维断裂强力。在理论分析的基础上,本文亦通过锡林梳理纤维前后的短绒含量变化验证理论车速值的可靠性,并提出“柔性精梳率”的概念。本文的研究可为具有高梳棉质量的新型高速棉精梳机及其梳理专件的研制提供理论依据。

Abstract: When cotton comber is carding at high speed, fibers damage and breakage would be caused by its cylinder carding, which influences on the combing quality. Therefore, this paper aiming at the cotton fiber breakage, constructs the theoretical velocity model of cotton comber on the condition that the cotton fibers are not ruptured, and also calculates the maximum theoretical velocity of cotton comber, namely “flexible combing value”. This theoretical velocity model considers the average carding force of single fiber in the process of combing as well as the breaking strength of cotton fiber. Based on the theoretical analysis, this paper also verifies the accuracy of theoretical velocity according to amount variation of short fibers between before and after the cylinder combing, and proposes the concept of “flexible combing ratio”. This study will provide a theoretical foundation for the development of new type of high-speed cotton comber and its carding part both with high-quality combing.

Key words: soft combing, soft combing value, soft combing ratio, average carding force, maximum velocity, fiber breakage
