"Two or more single strands may be twisted together to form ply yarn. Knitting yarns have less twist than weaving yarns. Thread, used for sewing, is a tightly twisted ply yarn. "
针织用纱捻度比机织用纱少,可以是单纱或股线。缝纫用线是具有圆截面的紧密加捻的合股线。
2.
"Spinning is the process of drawing out and twisting a mass of cleaned, prepared fibres. Filament yarns generally require less twist than do staple yarns."
纺纱是对纤维集合体牵伸加捻的过程。长丝比短纤维需要的捻度少。

4.
Also, it is more uniform but somewhat weaker than ring- spun yarn.
另外,无捻纱比环锭纱条干更均匀,强度则略低
5.
Used for testing the twist and twist irregularity of all kinds of yarns.
用于测定各种纱线的捻度及捻度不匀率。
6.
"More twist produces stronger yarn; low twist produces softer, shinier yarn."
捻度较大的纱强力好,低捻纱柔软有光泽,高捻产生皱纱。

The Experimental Analysis of the Untwist Retwist Methods in Determining the Twist of OE Yarn
对测试转杯纱捻度的几种退捻加捻法的实验分析
8.
Selfil yarns are slightly more even than ring- spun and are much stronger because of the filament wrapping.
长丝自捻纱比环锭纱条干要均匀一些,同时,由于长丝的包缠,其强度也要高一些。
9.
The yarn is twisted, exposed to heat which sets the twist in place, cooled and untwisted.
长丝首先被加捻,再被加热,在加热时使捻度定型；然后冷却,最后除去捻度。

11.
Unbalanced yarns have sufficient twist to kink.
卷缩的纱线捻度过高会产生扭结。
12.
Insufficient twist, inadequate number of fibers in the yarn cross-section.
捻度不够，在纱截面内纤维根数不足。

纱线捻度的测定: 直接计数法
14.
False -twist methods develop texture in filament fibers through the use of controlled heat.
假捻法利用可控制的温度使长丝变形。
15.
The strength of yarns is due, in part, to the amount of twist that has been imparted. Strong yarns require considerable twist. However, beyond an optimum point additional twist will cause yarns to kink and finally to lose strength.
影响纱线强力的因素之一是捻度的大
16.
As the yarn becomes finer, it requires more twist; heavier yarns can have very low twist and be durable.
纱线越细,要求的捻度就越大。粗重的纱线可以使用较低的捻度,但强度较大。
17.
As the twist is removed, the filaments kink or crimp sinusoidally because of the distortion resulting from the presence of the heat - set twist.
捻度被解除后,长丝会扭结或形成波状卷曲,这是捻度热定型引起的变形。
