【摘要】 为了设计高效能新型金属针布,我们对近期引进的瑞士Graf T—2525、日本金井CC80F—LH和国产SC₃等三种金属针布的分梳特性进行了系统的实验测试和综合的理论分析。采用梳理力测定仪,对三种针布在梳理区中实际梳理强度及其变化规律进行了系统的实验测定。用示踪方法对三种针布梳解纤维束的效能以及均匀混和性能进行了实验。用特试方法对三种针布在梳理区中盖板的残留纤维量、自由纤维量和转移率等梳理特性进行了实验。用常规方法对不同针布纺制的生条和成纱质量进行了系统的对比试验。通过多种测试手段的实验,揭示了引进针布在锡林盖板梳理区中的梳理强度及其变化规律;摸清了梳理负荷的变化特征及纤维的转移特性;查明了引进针布的梳理、除杂、均匀及混和作用的基本特性。通过系统的实验和综合的分析研究,在实践和理论二方面深化了对引进针布的设计思想及其工艺性能的认识。在此基础上我们设计了新型高效能金属针布。更多还原

【Abstract】 Sysmatic experiments on carding properties of 3 kinds of MCC (Graf, Switzerland; Type CL 80 FLH, Kanai, Japan; Type SC 3, China) were made with carding-force-meters; the efficiency of carding and mixing was tested through racer experiments; the content of fibres remained uncarded on tops in the carding area, the free fibre content, as well as the fibre transfer rate were measured with special-test-method; quality indexes were compared in a regular way. This article discloses the carding strength and its changing regulars on tops in the carding area. Based on all of this, a new kind of high efficiency MCC has been designed.更多还原
