纱线的退绕是纺织生产中重要的一环。
Yarn unwinding is a key process in textile production systems.
经纱从织轴上退绕下来后穿过停经片，每根经纱穿过一个停经片。
After being removed from the warp beam, the end is threaded through a drop wire. There is one drop wire per end.
该区只包括一个筒子架，卷装在筒子架子上处于有利于退绕的最佳位置。
This zone merely consists of a creel, which holds the old package in an optimum position for unwinding.
转杯纺筒子纱不同退绕方式的试验数据分析表明：逆时针退绕严重恶化纱线条干。
This paper analyses test data of rotor spinning package unwinding way, and makes clear that anti clockwise unwinding way worsens yarn evenness heavily.
浆纱机经纱退绕张力控制系统缺乏精确的数学模型，且具有非线性和时变性的特点。
Warp unwinding tension control system for sizing machine lacks an precise mathematical model, and has nonlinear and time-varying Characteristics.
生产设备由熔喷铺网装置、热熔材料输入装置、机织物退绕装置、热轧机和卷绕机组成。
A production device consists of a melt-brown mesh paving device, a hot-melt material input device, a woven fabric unwinding device, a hot rolling machine and a coiling machine.
如果不能做到这一点，筒子的回转力矩会使它继续转动并退绕纱线，而退绕的纱线不能被卷绕到新卷装上。
If this is not done, the rotational momentum of the spool will cause it to remain in motion allowing yarn to be unwound without being taken up.
