Optimization of Ramie/Microfibers Polyester Spinning Process;

通过正交试验法 ,重点对纺制苎麻 /细旦涤 (R5 5 /T4 5 ) 9 8tex低特纱的细纱工艺进行了优

Self - Twist Self - twist yarns are essentially two - strand or two - ply (or more) yarns.

自捻纱基本上由两根或两股(或多股)纱组成

Furthermore, in knitted structures, Selfil yarns snag and pull less than ring- spun yarns.

另外,自捻纱用于织造针织品时,与环锭纱相比,纤维不易被拉出。

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。

Determination of twist in yarns-Untwist-retwist method

GB/T2543.2-1989纱线捻度的测定退捻加捻法

Self- twist spinning produces yarns more cheaply than ring spinning and considerably faster with less labor.

自捻纺纱与环锭纺纱相比,成本较低,生产率高,而且节省人工。

Assuming the yarns are single spun yarns, the tensile strength of the yarns needs to be improved. At this point, the major strength that the yarns possess is that derived from the twisting of their fibers.

假设使用的是短纤维单纱,纱线的强力需要增加,单纱的强力主要来自对纤维的加捻。

"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。
