Change in roving lilac Polyester Yarn or trial spinning, generally choose the axial winding density, determine the number of teeth of the lifting gear, and then determine the starting position of the iron cannon, adjust the yarn tension, and select the tension conversion gear according to the variety.
The spindles of the individual spindles are basically related to the sway of the spindle, the deformation of the pressure palm, and the bobbin jump, which is not a major contradiction..5% in advanced plants. Drawing due to unreasonable process design such as roller gauge, draft distribution, number of merging, etc. Pure polyester and coarse temperature and humidity requirements: 24 degrees to 32 degrees; 55% to 60%; 2.
The moving round toothed rod should be cleaned regularly with a wire brush. It causes the increase of short pile and cannot effectively exclude short pile (such as unreasonable linear speed ratio of tin barbed wire, excessively high speed of barbed roller, slow speed of cover plate, and insufficient negative pressure of dust removal system), cotton bundle (fiber) in the sliver (Bundle) existence; 3. What is the reason why FA458 roving has unstable yarn tension? Answer:
There are many factors that affect the size and uniformity of roving tension, such as raw materials, temperature and humidity, process, false twister and bobbin diameter, so to control the tension of each doffing, we must proceed from the following aspects: 1. Who knows what’s going on, please give pointers. One is that the roving is not stretched, and the other is that the drafting area is not stretched.
