Problems solved by technology

However, the slivers produced by these methods are prone to problems such as unevenness, fluff, uneven distribution of stainless steel fibers, and easy elongation and breakage of the slivers; , high production cost
In the mixed pull and combined method, the phenomenon of missing cutting of stainless steel wire bundles is easy to occur, and the quality of pulling and cutting is difficult to guarantee

Abstract

A method for draft-breaking the stainless steel fibre tow used for weaving the stainless steel fibre fabric features that the stainless steel fibres and drafted for breaking them to obtain the fibres with the proper length distribution suitable for spinning technology. It is possible that the broken stainless steel fibres are wrapped by conventional ribbon. Its apparatus is the reformed double.

Description

technical field [0001] The invention relates to the textile industry, in particular to a method and device for pulling and cutting stainless steel fiber tow. Background technique [0002] Stainless steel fiber filament bundles cannot be directly used for ring spinning. In order to adapt to spinning production like conventional fibers, it needs to be pretreated before spinning to cut and break the stainless steel filament bundles. At present, special drawing and cutting equipment is generally used to cut stainless steel filament bundles into stainless steel fiber pulling and cutting strips. The way of stretching and cutting has separate strip making; some stainless steel fibers are cut into short fibers and then used, such as patent CN 1044983C; there are also mixed stretching and cutting mixed with other fibers into strips (production of blended fibers) product use). However, the slivers produced by these methods are prone to problems such as unevenness, fluff, uneven dist...
