Singeing machine singeing machine singeing purpose

When fibers rub during spinning and weaving, many short and loose fibers are exposed on the yarn surface, and a layer of short fibers stands on the fabric surface. If you flatten the cloth, you can see this layer of fluff with different lengths along the cloth in front of your eyes. This layer of fluff not only affects the smoothness of the fabric, but is easy to be contaminated with dust, and also produces various defects in printing and dyeing. If fluff falls into mercerizing alkali liquor, impurities in alkali liquor will increase, which will affect mercerizing luster and make it difficult to recycle alkali liquor. When the fluff falls into the printing paste, it is easy to drag the paste and the knife, which affects the clear pattern. The fluff on the surface of polyester-cotton fabric is easy to pilling and so on. Therefore, except for some special varieties, general cotton and linen fabrics and polyester, vinylon, acrylic and cotton blended fabrics should be singed before desizing and bleaching. Some worsted fabrics, silk fabrics, knitted fabrics and yarns should also be singed according to the processing requirements.
