Composite fabric information for finishing woven fabrics

The finishing process is the last process in the production of woven fabrics. It usually includes fabric inspection, folding, grading, trimming, washing, and packaging. 1. Cloth inspection Cloth inspection is carried out by cloth inspectors on a cloth inspection machine. The main task of fabric inspection is to inspect various yarn defects and weaving defects on the surface of finished fabrics, and perform scoring, marking and minor repair work according to standards, and provide timely feedback on major defects found. 2. Folding: The basic task of the folding process is to neatly fold the inspected cloth into pieces according to the specified folding width. At the same time, the length of the cloth is recorded, stamped, and released according to variety and defect category. 3. Grading The main task of this process is to grade the fabric according to the relevant standards and defect marks, and at the same time grasp the scope of repair, weaving and washing. 4. The main task of this process of repairing, weaving and washing is to repair, darn and wash the defects that have been downgraded but will not affect the quality and require little labor after repairing, weaving and washing according to the prescribed scope. , to improve the quality of the cloth and increase its use value. 5. Packing The main task of the packing process is to pack the graded, trimmed and washed cloths separately according to the requirements of domestic and export sales according to relevant packaging standards and methods, and to make packaging marks in accordance with regulations. The above is a brief description of the production process of natural cotton cloth. The weaving preparation of dyed fabrics is more complicated than that of natural color fabrics. The warp and weft yarns generally need to undergo pre-processing such as scouring, bleaching, mercerization, dyeing, and drying before weaving preparations similar to those of natural cotton fabrics. After the fabric is woven, the finishing process is generally more complicated than that of natural cotton. In the weaving process of wool fabrics, except for the light single warp products in worsted wool fabrics and the low special (high count) products in woolen wool fabrics, generally wool fabrics do not go through the sizing process. Instead, the wool warp yarns are processed during the warping reel. The purpose of oiling, waxing or synthetic sizing emulsion is to increase the smoothness of the warp surface, reduce friction during weaving, and reduce end breaks and weaving defects. After the fabric comes off the machine, it must be finalized (measured in length and width), weighed and inspected, and then the fabric will be graded according to standards. Defects will then be repaired according to regulations, stains will be cleaned, and yarn ends and loose wool will be cleaned. Clean up debris. Finally packaged and stored in warehouse. The preparation before weaving of silk fabrics is quite different for the three types of plain warp and flat weft fabrics, crepe warp and crepe weft fabrics, and cooked goods fabrics, as well as their different varieties. For the warp and weft yarns of pure silk plain warp and weft fabrics, there is usually a dipping process before winding. The main purpose is to evenly soften the sericin, make the silk body soft and smooth, and reduce friction. The rest of the process is similar to the preparation process of natural cotton cloth. For the preparation of warp and weft of viscose plain warp and weft fabric, we start with warping and weft rolling respectively, and no other preliminary preparations are arranged. For the warp and weft yarns of crepe warp and weft fabrics, processes such as doubling, twisting, shaping, and rewinding are added after impregnation and winding. The warp yarns do not need the warp sizing process. For the warp and weft yarns of cooked fabrics, there is no need to go through the impregnation process. After the shaping process of preparing the warp and weft yarns of crepe warp and crepe weft fabrics, the processes of twisting, dyeing, color yarn picking, and re-entangling are carried out, and then warping, warping, and weft yarns are carried out respectively. The warp and weft are knotted and finally weaved. There is no need for starch. After the fabric is woven, its finishing process is similar to that of the natural cotton fabric mentioned above, including the processes of warping, inspecting, trimming, darning, embroidering the silk, rolling the silk, grading the silk, and warehousing and handing it over.
