Suzhou Zhanheng intelligent introduction: What is the process treatment of spinning machine? 

 It is the tow from different silks that is synthesized into one strand and introduced into the post-treatment production line under certain tension. The number of strands required for a draft piece depends on the total fineness required for the post-processing draft and the operating speed. The whole draft sheet will be divided into three pieces for post-processing. 

After leaving the three-pass draft machine, the tow enters the stack rack, where the three strands are folded into one piece and fed into the crimp machine to be heated by the crimp heating box. The crimping range of the tow can be achieved by adjusting the pressure of the crimping machine. 

The crimped tow is oiled once and then fed into a wire dryer (relaxation heat setting) to dry evenly. This unit is divided into four zones and heated by an air circulation system heated by steam. In the first two. Zone the tow gets dried. In the latter two regions, the tow is treated and contracted freely. In the first draft zone between the one draft machine and the second draft machine, the tow is the main draft, and 80% to 85% of the total draft ratio is completed by 50 ~ 80℃ hot water bath. A pre-orientation is obtained and the tow is heated by a water bath. After leaving the second draft machine, the tow enters the tension heat setting unit.
