Method for producing multicolor section color yarn and drawing frame device

Abstract

The invention discloses a method for producing multicolor section color yarn. Main color rough yarn and secondary color rough yarn are adopted to be spun on a three-roller ring spinning section color yarn spinning frame, so that the multicolor section color yarn is obtained. The main color rough yarn is continuously fed in from a middle-roller horn mouth, the secondary color rough yarn is continuously fed in from a rear-roller horn mouth, pre-drawing strips with two or more colors are adopted for the secondary color rough yarn and fed into a cotton-feed roller of a drawing frame in parallel when the drawing procedure is carried out for combination, pre-drawing strips of the same color are concentrated and fed into the cotton-feed roller of the drawing frame in parallel, then the yarn roughing procedure is carried out on the pre-drawing strips, and accordingly the single multicolor secondary color rough yarn is formed. A traditional three-roller ring spinning section color yarn spinning frame is adopted in the method, multicolor section color yarn products with different effects can be produced without the need of improving spinning equipment any more, industrialization and mass production of the multicolor section color yarn products can be achieved through the production method, and cost of manpower and material resources is saved.

Description

technical field [0001] The invention relates to the field of textile color spinning, in particular to a method for producing multi-color segment colored yarns. Background technique [0002] In recent years, with the increasing demand for fashionable and personalized clothing, cotton-spun fancy yarn has become an important branch in the textile industry, and has attracted widespread attention, especially the multi-color segment colored yarn developed and produced in recent years. , which meets the requirements of modern people's personalization, differentiation and fashion, and is loved by people. [0003] However, the multi-color segment colored yarns on the market not only have complex production equipment structures and are difficult to transform, but also use multiple rovings or filaments for production, which is difficult for workers to produce and operate, poor product quality stability, and high cost, making the products industrialized in batches. Production is severe...

Problems solved by technology

[0003] However, the multi-color colored yarns on the market are not only complex in production equipment structure and difficult to transform, but also use multiple rovings or filaments to produce, which is difficult for workers to operate, poor product quality stability, and high cost, making the product industrialized in batches. production is very limited

[0004] For example, the domestic application number is 2013103333469, which discloses a spinning method of multi-component multi-color segment colored yarn. The ultra-large draft spinning frame with apron three-zone drafting adopts ring-spinning ultra-large draft four-roller section colored yarn equipment, which has a complex structure, inconvenient maintenance and production, high manpower and material costs, and mass industrialization Production and application are difficult; moreover, it uses three rovings to make multi-color colored yarns, one of which is the main color roving, and two are auxiliary color rovings. For the production process of the three rovings, the production operation is complicated, and one worker must simultaneously Looking after several machines, it is easy to have quality problems, which limits its industrial application

The utility model patent with the domestic application number of 2013201837758 discloses a multi-color embedded segment color spinning device, which mainly uses four feeding rollers independently driven by servo motors to form a drafting area with the front rollers. The negative pressure tube, mesh ring and mesh ring driving roller constitute the negative pressure holding and slippery moving mechanism of the roving sliver, and the feeding roller is controlled by the computer program controller to realize the intermittent feeding and drafting of the four roving sliver fibers , using the twisting of two filaments and their own rotation during the twisting process, the fiber strands output in segments are twisted into the twisted yarn to realize multi-color embedded segment color spinning; but embedded segment color spinning The yarn device has not yet been applied in industrial mass production, because the equipment is very complicated, difficult to maintain, difficult for workers to operate during the production process, and the output is low
