Background technique

With the advancement of modern technology, the new stainless steel fiber process can produce filament bundle fibers with a diameter of less than 30 microns for use in new spinning fields, such as making antistatic clothing, high-voltage clothing, etc. mesh material. However, since the stainless steel fiber is a long bundle, the general process is to use a cotton drawing frame or a fiber breaking machine to break it to the required length of 40-90 mm. Due to the brittleness of the stainless steel fiber and the toothed roller under high pressure, it will break A large number of micro-short fibers will not only damage the surface of the fiber and affect the strength of the stainless steel fiber, but also produce micro-short fibers that will affect the subsequent process and increase the loss of the fiber itself. At the same time, there is no suction cleaning device, and the phenomenon of winding around the roll occurs from time to time, which greatly affects the production efficiency and restricts the production range.
