High ratio blended spinning technique for ultrashort low-density fibre based on cotton spinning device

Abstract

The present invention discloses the process of producing blended cheese yarn with high content of ultra short low density fiber in cotton spinning apparatus. A punching with high homogeneity and great cohesion is first produced through mixing ultra short low density fiber and other fiber in an opening and picking step much loosening and less beating; and then produced into cheese through the steps of combing, drawing, roving, spinning and coning. The blended cheese yarn consists of ultra short low density fiber 51-95 wt%, natural fiber 5-49 wt% and chemical fiber 5-49 wt%. The blended cheese yarn with high content of ultra short low density fiber is light, soft, lofty and high in strength, and its produced fabric has high color fastness.

Description

Technical field: [0001] The invention belongs to the field of spinning engineering in the textile industry, and more specifically relates to a high-ratio blended yarn processing method of ultra-short low-density fibers and a spinning process thereof. It can be applied to the preparation of blended yarns from ultra-short low-density fibers. Background technique: [0002] It is difficult for traditional cotton spinning equipment to spin ultra-short low-density fibers. The difficulty is that the fibers are light in weight and short in length. Compared with other natural fibers and chemical fibers, cotton plucking machines are easier to quickly, large-scale, and preferentially inhale ultra-short low-density fibers. fibers, while other fibers are relatively slow and low in ratio, and it is difficult to uniformly mix ultra-short low-density fibers and other fibers, which is not conducive to controlling the fiber components and mass percentages of blended yarns in a fixed ratio.

There are very few literatures on theoretically studying low-density, short-fiber yarns, although literature (Sunmonu O.K., Abdullahi D.Characterization of Fibers from the Plant Ceiba Pentandra.J.Text.Inst., 1981, 2: 273-274 ; Murdocco S.kapok fiber.
