Description

Combing technology of two different fiber laps

technical field

The invention belongs to the combing technology of cotton spinning, and in particular relates to the technology of simultaneous combing processing of two small rolls of fibers with different properties on the same combing machine.

Background technique

The current cotton spinning combing machine is mainly designed for the performance of cotton fibers. It is mainly used to remove short staples, neps, and impurities in cotton fibers, and improve the straightness, parallelism, and separation of fibers, thereby greatly improving Yarn luster, feel and wear performance. The combing process is characterized in that the shorter the fiber length, the higher the combing noil.

my country is a big producer of polyester fiber, and the production of polyester fiber and cotton fiber blended yarn is increasing year by year. In the traditional polyester-cotton blending process route, the combed cotton slivers produced after the cotton fibers are combed are mixed with uncombed polyester slivers before spinning. Since the polyester sliver has not been combed, the quality of the polyester-cotton blended yarn cannot meet the requirements of high-grade fabrics. In order to improve the quality of polyester-cotton blended yarn, some textile enterprises use polyester sliver and cotton sliver to be mixed in proportion to make small rolls (polyester-cotton blended), and then spun after combing. This method can greatly improve the polyester-cotton blended yarn quality. The quality of cotton blend yarn. However, compared with polyester fiber, cotton fiber has short fiber length and poor uniformity, so in the combing process, more cotton fiber is excluded, and polyester fiber is less excluded, so that the blending ratio of polyester fiber and cotton fiber in the yarn is That is, the blending ratio cannot be guaranteed, and the performance and style of the product are quite different from the requirements, which is difficult for users to accept.
