1. The purpose of fabric singeing
When the fibers are rubbed during spinning and weaving, many short and loose fibers are exposed on the surface of the yarn, and a layer of short fibers stands on the surface of the fabric. If the fabric is flattened, a layer of fluff with different lengths can be seen along the cloth surface. This layer of fluff not only affects the smoothness of the fabric and is easily contaminated with dust, but also causes various problems in the printing and dyeing process. For example, the fluff falls into the mercerized lye, which increases the impurities in the lye, affects the mercerizing luster and causes difficulty in recycling the lye: the fluff falls into the printing paste, which is easy to cause dragging and dragging of knives, affecting the clarity of patterns, etc., as well as causing polyester/cotton The surface fluff of the fabric is prone to pilling and so on. Therefore, except for some special varieties, general cotton, linen fabrics and polyester, vinylon, polyester and cotton blended fabrics should be singeed before deboiling and bleaching. Some worsted wool fabrics, silk fabrics, knitted fabrics and yarns need to be singeed according to processing requirements.
2. Working principle of singeing machine
Singeing is a process in which the fabric quickly passes through the flame of the singeing machine or wipes the red-hot metal surface in an open width state to remove the fluff on the surface of the fabric and obtain a smooth surface fabric. At this time, the fluff on the cloth surface heats up and burns quickly because it is close to the flame and loose. The fabric itself is relatively tight, thick, and far from the flame, so the temperature rises slowly. When the temperature has not reached the ignition point, the fabric has left the flame or the red-hot metal surface. The principle is to achieve the purpose of only burning the fluff on the surface, but not damaging the fabric.
3. Types of singeing machines
There are two ways of singeing, namely contact singeing and non-contact singeing. Contact singeing machine includes copper plate singeing machine, cylinder singeing machine and electric hot plate singeing machine. The non-contact singeing machine is a gas singeing machine. At present, the gas singeing machine is widely used, the copper plate singeing machine and the cylinder singeing machine are not used much, and the electric hot plate singeing machine has been basically eliminated.
