Through calculation of the mini vlaue of the complementary angle of front angle α,conclusion is made that the impact of complementary angle of front angle on the carding effect is an important factor to the figuration of new clothing in addition to the factors such as performance of the processed fiber,carding process,and production condition.
为了正确选用配套新型针布,阐述了锡林-盖板工作区纤维转移的4种情况,重点对针尖上纤维的受力进行了分析,通过对前角余角α最小值的计算,指出新型针布的选用配套除考虑被加工纤维的特点、梳棉机的工艺及纺纱条件的要求外,须重视锡林针布齿条前角余角对梳理的效果的影响;对于高产梳棉机,随着梳棉机产量的增加,前角余角α应减小,对于低速梳棉机,应选用大前角余角的针布齿条,从而使纤维能够在锡林-盖板区多次被剥取,形成有效梳理。
