A short-flow spinning method

Abstract

The invention discloses an efficient short-flow spinning method, which includes: plucking selected polyester fibers by a disc plucker, opening and cleaning the plucked fibers by a Kirschner opener, and making polyester rolls by a single-beater rolling machine; carrying out two-way lap doubling on the polyester rolls to obtain small polyester rolls with improved uniformity and fiber straightness; producing polyester slivers with the obtained small polyester rolls by carding machine, and carrying out two drawing processes to obtain polyester drawn slivers with improved evenness and fiber straightness; carrying out roving on the polyester drawn slivers, spinning, and spooling to obtain required polyester yarns. According to the method disclosed by the invention, the evenness and fiber straightness of the polyester rolls are improved by bidirectionally lap-doubling the polyester rolls produced by short-flow opening and cleaning, so that the high quality of yarns is realized under the condition of a short flow.

Description

technical field [0001] The invention relates to the field of textile new technologies, in particular to a short-flow spinning method. Background technique [0002] At present, China's textile industry is undergoing a critical period of transformation from labor-intensive to technology-intensive. Intelligent and continuous textile production has become a symbol and an inevitable trend of modern textile factories. Traditional weaving adopts the process of spinning first and then weaving. The specific weaving steps are: loose fiber opening and impurity removal, mixing, carding, combing, one-way drawing, two-way drawing, roving, spun yarn, winding, warping, Sizing, threading and knotting, weft yarn preparation, and weaving; the specific weft knitting steps are: loose fiber opening and impurity removal, mixing, carding, combing, one-way drawing, two-way drawing, roving, spun yarn, winding, Heat set, weft knit. The main problems in traditional textile processing are: traditional...

Problems solved by technology

The main problems in traditional textile processing are: traditional ring spinning requires many procedures, long process, labor intensive, time-consuming and high cost to process bulk fiber into yarn. Efficient and high-quality short-process spinning is the key to shorten the textile process. Basic: The weaving preparation and weaving process after the spinning and spun yarn process are long and the running speed is high, and the quality requirements of the yarn are high in wear resistance, strength, and hairiness. Unclear weaving shedding reduces weft insertion efficiency, yarn wear resistance and low strength lead to high frequency of weaving warp yarn breakage, low weaving efficiency, and poor quality of final products; The range of yarn counts is wide, but spinning is restricted by factors such as fiber length, stiffness, and number of fibers, especially if the fiber length is too short, the internal and external transfer cohesion of fibers is insufficient during the yarn forming process, the yarn forming strength is low, and spinning ends are frequently broken , unable to spin continuously
