在上述三种退捻加捻法中,三倍退捻加捻法测试转杯纱捻度的测试结果最大,其次是二重法和一次退捻加捻法。
Test result obtained with triple twisting method is the greatest, then is those obtained with double twisting method and one time back twisting and twisting method (GB 2543-81).
研究表明,纱线退绕时在筒子表面的滚动现象是导致断头、乱纱问题的主要因素,从而说明筒子纱的捻向与卷绕方向的选择对退绕质量有直接影响。
The impact caused by bending direction to forming parts design as well as the structural design of bending and splitting compound working procedure are stated in details.
