Composite yarn formation method of built-in powder materials

Abstract

The invention relates to a composite yarn formation method of built-in powder materials, and belongs to the technical field of textiles. The method comprises the steps that firstly, non-woven flexiblefabric materials are divided into fiber strips S1 and fiber strips S2; secondly, a padding method is adopted for conducting padding combination on the fiber strips S2 and powder to form powder stripsS2'; finally, each composite strip formed by sandwiching one powder strip S2' with two overlapping fiber strips S1 is subjected to composite twisting and yarn formation by adopting a flyer spindle twisting and winding mode, and the linear sheet-shaped composite strips are converted into linear cylindrical yarn. The sheet-shaped untwisted loose-state structures of the composite strips are changed,the technical bottleneck that it is difficult to comb and collect powder into strips by means of traditional methods is broken through, the built-in short-flow yarn formation of powder materials is achieved, the technical purpose of the composite yarn formation of the powder materials is achieved, and the quick and effective method is provided for preparing high-functionality high-quality yarn and apparel fabrics by using the powder materials. The method is short in process flow and easy to popularize and apply.

Description

technical field [0001] The invention relates to a composite yarn forming method with built-in powder materials, which belongs to the technical field of textiles. Background technique [0002] Textile fabrics used in clothing can be divided into three categories: woven (woven), knitted and non-woven fabrics. Woven and knitted fabrics are woven from yarns or filaments through a weaving process; non-woven fabrics (also known as non-woven fabrics) are processed from textile fibers by bonding, fusing or other mechanical and chemical methods. Woven fabric is a fabric formed by interweaving warp yarns and weft yarns perpendicularly to each other. The fabric weaves include plain weave, twill weave, satin weave and the weaves formed by the above three basic weaves and their intersecting changes. Knitted fabrics are formed by forming yarns or filaments into coils, and then interlocking the coils. Due to the coil structure of knitted fabrics, there is a large amount of yarn stored per...

Problems solved by technology

In traditional textile processing, there are three major technical problems: First, 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 solution to shorten the textile The basis of the process; second, the weaving preparation and weaving process after the spinning and spinning process have a long process and high operating speed, and have high requirements on the quality of the yarn such as wear resistance, strength, and hairiness. Broken needle around the crochet needle or unclear weaving opening reduces the efficiency of weft insertion, and the wear resistance and low strength of the yarn lead to high frequency of woven warp yarn breakage, low weaving efficiency, and poor quality of the final product; thirdly, although traditional ring spinning Yarn cohesion is high and the range of spinning 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 (length less than 20 mm), and the fiber transfers from inside to outside during the yarn forming process. Insufficient cohesion, low yarn strength, frequent spinning end breaks, and inability to continue spinning

However, nanofiber non-woven membranes and conventional fineness fiber non-woven fabrics have the following defects: 1) The strength and durability of non-woven fabrics are poor, which cannot be compared with traditional textile fabrics, and cannot be used instead of traditional textile and clothing products; It is difficult to be used for clothing fabrics as other fabrics are cleaned; 3) The fibers are arranged in a certain direction, and they are easy to split from right angles, etc.

Obviously, although the yarns provided by the above two koans have a certain strong linear continuous feature, the yarn structure is flat and lacks the cylindrical structure of fiber twisting and entangling, which is very different from the structure of conventional textile yarns and is not suitable for conventional textiles. The yarn running and yarn guiding channel of textile equipment cannot really be integrated into the conventional batch yarn weaving equipment and production process, and it does not solve the problems of ultra-weak (nanofiber, etc.), ultra-short (short pile), high stiffness and brittle (carbon fiber, glass fiber) , quartz fiber, etc.), high resilience and super bulkiness (down-like fiber), powder (fiber whisker, carbon nanotube, graphene, various nano-microspheres, nanoparticles) and other difficult-to-spin materials how to spin, Due to the technical problems of weaving, ultra-short fibers are generally used in papermaking, composite material reinforcement fillers, and flocking product development.
