How to harmonize hair
The purpose of hair removal has been described earlier. Hair removal is an important process that affects product quality. The impact of the wool blending process on quality is mainly reflected in the uniformity and moisture regain. Uniformity includes the uniformity of the mixed wool (composition and color sweat), and the uniform blending and oiling of the wool. If the wool blending and adding water are uneven, it will cause uneven dryness and increase the difficulty of subsequent processes. Uneven color mixing of dyed wool will cause weaving defects such as spots on the fabric surface, which will directly affect product quality and the normal progress of the finishing process. The moisture regain rate of the mixture must meet the process requirements. If the wool is too wet, it is easy to wrap around, causing damage to the card clothing and raw materials, increasing wool particles in the wool net, and affecting the spinning quality. If the hair is too dry, the fiber will be easily damaged when combing, and the static electricity will be high, resulting in a lot of flying hair and falling hair, which will reduce the production rate. Uneven dryness and wetness affects even dryness and normal production. The uniformity of the hair is related to the hair technology and the hair method. The wool blending method is to “lay it horizontally and take it straight (or lay it flat and take it straight)”. That is to say, put various raw materials into the opener in proportions. After entering the pipe, use the spray nozzle to spray various fibers into the wool blending bin. When the fibers are sprayed together, the nozzle can be retracted and reciprocated, so that the fibers are initially mixed and laid flat into a wool layer. Then the fiber grabber vertically grabs the flat fibers and continues to mix until the fibers are evenly mixed.
