盖板梳理理论的新解

New Explanation of Theory of Flat Carding

利用力学分析对盖板分梳的基本作用、盖板梳理区纤维的运动以及盖板踵趾面做了重新审视并提出了新的见解.盖板在梳理作用中有吸收与放出纤维的功能,从而产生所谓的转移分梳作用以及均匀混合作用,这成为盖板梳理的特点与理论基础.此外,讨论了针布纤维负荷、锡林转速和道夫的纤维转移率对棉条生产和品质的影响.

Mechanical analysis is used to analyze the basic action of carding,the fibre motion in the flat carding zone,as well as the function of flat heel and toe,and new explanations are reached.The working flats have the functin of adsorbing and desorbing fibres during carding action,thus producing so called transferring carding action with blending and evenning action which constitute the theoretical basis and sepcial feature of flat carding.In additon,the effects of fibre loading in card clothing cylinder speed,fibre transferring ratio by the doffer to the quality and producton of sliver are discussed.
