When inspecting grey fabrics, there are individual grey fabrics at the head or end of the fabric (between 30 and 35 meters), often found to be massive pulp spots with no regularity. Sometimes there is a large area of ​​pulp stains, which is brown and cannot be woven in the finished product workshop, and it causes an inestimable loss to the downstream dyeing and finishing. It can only be cut or lowered. How to prevent the causes of production. 1. When starting up, as long as the cylinder temperature is low, the resurgence is large. 2. When starting, (Zukke sizing equipment is very obvious) the sizing tank slow speed (1 speed) and express speed 2 speed tension, the intermediate value of sizing force is large, and it is generated during the conversion between slow speed and express. Take measures against pulp spots 1. After the machine is installed, the sizing stopper and the adjuster coordinate to flush the slurry pipe, and the return pipe keeps the pipe clean and avoids lumping in the pipe. 2. The driver must clean the pulp tank before driving, some steam, crawling speed, to the warp beam head cloth, so that the immersion rollers in the pulp tank, the sizing roller and the sizing roller are clean and no dead angle. 3. The air lock of the edge of the slurry tank is opened to the 1/3 position, to avoid the phenomenon that the slurry on the edge is not smooth and easy to skin, and it also has a thermal insulation effect, and the effect is significantly good. Take measures against slurry 1. Before driving, ask the blocker to set the pre-bake temperature at 100 degrees and the main cylinder temperature at 95 degrees, and drive only after reaching the predetermined value. 2. Before driving, set the tension. The intermediate value of the warm yarn tension slow train and the fast train should be shortened as much as possible. 3. Before driving, the setting of squeezing force can be adjusted upwards by 5,000 N in accordance with the process regulations, and adjusted to the process range before being transferred to normal driving.
