The invention also discloses a flocculus processing method. The method can be flexibly operated according to the properties of the raw materials, and is suitable for natural cotton, chemical fibers and modified cotton, and the processed flocculus has good bulkiness and wide application range. In addition, the invention also discloses the flocculus processed by using the equipment and the method, the raw materials used for the flocculus can be flexibly selected and proportioned as required, and the bulkiness is good.

Description

technical field [0001] The invention relates to a flake processing device and a processing method, and also relates to flakes processed by the device and the method. Background technique [0002] First of all, during the drying and setting process of traditional polyester spray-bonded cotton, it has to go through dozens of metal rollers and rubber in close contact with continuous friction. In addition, the fabric has low moisture content at high temperature, poor conductivity, and it is difficult to leak electric charges, which causes static electricity. The continuous accumulation of charges. When the electrostatic voltage of the operating part is too high, the operator often suffers from a strong electric shock. In addition, the repulsion and attraction caused by static electricity will also cause difficulties in fabric folding, affecting the processing process and product quality. At present, in the processing operation of spray-bonded cotton carding, it is generally lu...
