Split spinning yarn production method, split spinning yarn and spinning frame

Abstract

The invention provides a split spinning yarn production method and a spinning frame. The method comprises the following steps: simultaneously feeding a plurality of rovings into a drafting zone of thespinning frame for synchronous drafting, respectively bundling the plurality of rovings through the spinning frame, and compounding and twisting the plurality of rovings to obtain split spinning yarn. The split spinning yarn prepared by the method is a unique split twist structure effect yarn on the market at present, a new spinning structure form is formed, the market gap is filled, market categories are enriched, the product added value and enterprise competitiveness are improved, the cost is low, complex transformation on a spinning frame is not needed, the operation method is simple, andmanpower and material resources are saved.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for producing a split-spun yarn, a split-spun yarn and a spinning frame. Background technique [0002] In recent years, with the diversified demands of consumers for clothing fabrics, new personalized textile products have been favored by consumers; in today's increasingly competitive textile industry, only by constantly changing the properties of raw materials, yarn structure, fabric structure and post-processing Only by finishing technology and endowing products with new performance and characteristics can we continue to meet the needs of the market and consumers. [0003] Yarn structure is the main factor that embodies the quality performance and appearance characteristics of yarn and fabric. In traditional ring spinning, the physical and mechanical properties of the yarn can be further improved by changing the yarn structure; for example, on the basis o...

Problems solved by technology

[0004] There are also some new spinning methods, such as Patent No. 1: CN 105624848 A, a multi-roving feeding spinning device and spinning method, which uses a frequency conversion motor to drive the four rollers independently, and the rovings are fed from the first and second rollers respectively. , The third and fourth rollers are continuously or intermittently fed and drawn, and twisted into yarn; another example is Patent No. 2: CN 107012559 A, a four-roving double-drawing fancy yarn production device and production method, which also uses a frequency conversion motor The four rows of rollers are individually driven, and the third and fourth rollers are fed in alternate steps of roving intermittently, and a collective bell mouth is installed between the jaws of the middle and rear rollers to gather, and then the yarn is drawn and twisted; the above Both inventions adopt a large-scale technical transformation of the ring spinning frame, transforming the traditional three-roller drafting into four-roller drafting, and the four rollers are independently driven by servo motors to control the feeding of the roving, and the transformation costs are expensive. The production operation is cumbersome, the cost is high, and the energy consumption is large

[0005] In view of the above problems, the object of the present invention is to provide a split-spun yarn and its production method to solve the technical problems of high cost, cumbersome operation and high energy consumption of the existing split-spun yarn.
