Method for improving embossing quality of sawteeth

Abstract

The invention relates to a method for reducing the binding force between cotton fibers and cotton seeds and improving the embossing quality of sawteeth by carrying out online humidifying and heating on the cotton seeds and belongs to the field of textile processing. According to the invention, gas inlet micropores which are uniformly distributed are arranged on a cotton flow-down plate in a feeding region of a sawtooth cotton gin; the cotton flow-down plate is connected with a steam passage; high temperature steam is filled into the cotton flow-down plate to carry out high temperature heat and wet treatment on seed cotton passing through the cotton flow-down plate; the processed seed cotton enters an embossing region and is subjected to further treatment by high temperature steam output by a first steam outlet hole and a second steam outlet hole; the binding force between the cotton fibers and cotton seed hulls is greatly reduced; under the tearing action of a high-speed rotating sawtooth wheel, the separation of the cotton fibers from the cotton seeds from the roots is implemented; the breakage of a great amount of fibers, which is caused by the case that the cotton fibers are randomly broken by the sawteeth, is fundamentally inhibited; the original fiber length of the cotton fibers on the embedded seed cotton is kept; and the embossing quality of the sawteeth is greatly improved. The method has the advantages of reasonable design and simple structure and is suitable for large-area transformation of the sawtooth cotton gin.

Description

technical field [0001] The invention relates to a process of online humidification and heating of seed cotton during the sawtooth ginning process to reduce the binding force between cotton fibers and cottonseeds, greatly increase the ratio of cotton fibers extracted from the surface of cottonseeds, and reduce the rate of cotton fibers in the sawtooth ginning process. The invention discloses a method for improving the quality of sawtooth embossing by breaking fibers, belonging to the field of textile processing. technical background [0002] The top roller gin uses the top roller to pull the fiber, and the chopper cuts it from the root of the pulled fiber to realize the separation of the fiber and the cottonseed; in general, the long fibers in the lint produced by the top roller gin are less damaged, and a large number of long fibers was preserved. Therefore, foreign countries that grow long-staple cotton, such as Egypt, Sudan, and Morocco, also strictly stipulate the use of...

Problems solved by technology

[0003] However, using a sawtooth gin to process seed cotton will also bring a lot of side effects. This is mainly due to the fact that when the sawtooth separates fibers and cottonseeds at the working point of the ginning ribs, a large number of fibers are broken, and at the same time the friction between fibers and fibers, or between fibers and metal surfaces. Neps and tufts resulting from mild twisting

Therefore, in the lint produced by the sawtooth gin, a large number of long fibers are damaged and broken, the main length of the fiber is shorter, and the fiber quality is greatly reduced
