Description
Technical Field
The application belongs to the technical field of textile engineering, and relates to an acetate fiber stretch-breaking device and a production method.
Background
At present, acetate fibers are widely applied to the production of clothing textile and are favored by the world's well-known clothing design universities. The reasons for this include: a. the acetate fiber has the characteristics of good drapability, comfortable wearing, light stability, moisture absorption and the like, and the amorphous open pore structure can discharge moisture out of the body, so that the acetate fiber is more comfortable and cool to wear, and various skin-contacting clothes made of the acetate fiber are safe and environment-friendly; b. the acetate fiber has bright luster and excellent hand feeling like silk, and the fabric spun with the acetate fiber has soft and smooth hand feeling, dry and smooth property, good air permeability, quick drying and no electrostatic adsorption.
Although acetate fiber itself has many advantages, it has certain disadvantages in terms of strength and the like due to the inherent structure of its own material. To overcome these drawbacks, after intensive research, it was found that blending acetate fibers with other fibers was one of the approaches to solving textile weaving. The blending method comprises two modes of blending the wool tops and the sliver, and blending after mixing and carding the bulk fibers. If wool top blending is adopted, the dyeing characteristics of the acetate fiber are different from those of textile materials such as wool, cotton, chemical fiber and the like, the acetate fiber must be manufactured into materials suitable for drawing and spinning of the textile materials such as wool, cotton, chemical fiber and the like through a drawing process, so that the acetate fiber has practical administration value. However, if the conventional stretch breaking machine is used for making the acetate fibers, the acetate fibers are seriously damaged, the strength and the breaking elongation are reduced, the curl is reduced, and the length distribution of the made fibers cannot meet the poisson distribution requirement, so that the cohesion between the fibers is reduced, and the method is not suitable for subsequent drawing production of other fibers. In a word, the existing production and technical means at present can not realize stretch breaking and strip making of acetate fiber tows. If another mode of blending after mixing and carding is adopted, the acetate fibers are cut into the form of short fibers required by blending.
Therefore, in view of the current situation, there is a need to develop an acetate fiber stretch breaking device and method, which can process acetate fibers into slivers, staple fibers, and can meet blending requirements of various textile materials such as cotton, wool, chemical fibers, and the like.
