A cable twist is much like a twisted tuft, only the tufts are twisted their entire length, no matter of the filament sizes.
扭丝密集型轮刷与扭丝平型轮刷外形近似,但整条的刷丝簇都能被扭成螺旋状,而不论刷丝直径大小。
However, if you hold a short length of yarn vertically in your left hand and rotate it between the thumb and forefinger of your right hand while pulling upward, you can determine the twist direction.
然而,当你用左手竖直的拿着一小段纱线,再用右手的拇指和食指夹住纱线的另一头,一边向上拉,一边旋转,这时你就可以测出它的捻向了。
The influence of four parameters (basic yarn diameter, slub diameter, slub space and slub length) on the distribution of twist was analyzed using this model.
借助这一模型分析了竹节纱的4个参数(基纱直径、竹节直径、竹节间隔以及竹节长度)对捻度分布的影响。
In this paper, considering the coupling effect of bend-twist and the lateral change of span length in each curved plate beam, the simplified formulas for analysis of transverse load distribution in curved plate bridges are developed based on the principle of hinge-joined plate method.
本文基于铰接板法原理,考虑各曲板梁的弯扭耦合效应及其跨长的横桥向变化,导出弯板桥荷载横向分布的简化分析公式。
Influences on slubby yarn twist of three parameters such as slubby length, slubby space and slubby multiple are analysed by testing ring spinning slubby yarn twist.
