Abstract

The invention relates to a technique of latitude yarn preparation before color weaving. The invention features that after coloring and baking the cheese, it is directly put into production without cheese winding process. The technique requires the cheese is processed with water dissolvable waxy material while being processed with soften agent; a cheese stabling ring is needed to be installed when placing the cheese on the shelves for correcting the cheese position on the shelves, a back unrolling ring is further needed to be installed for keep the unrolling and cheese transition working freely. The invention is adaptive to various color textures production while maintaining the productivity and quality, lowering the production cost and shortening production cycle, creating social and economic profits.

Description

Technical field: [0001] The invention belongs to the field of textiles, and relates to a process method for preparing weft yarns before weaving dyed yarns. Background technique: [0002] Yarn-dyed products are favored by people because of their bright colors, many patterns, easy decontamination, soft texture and comfortable wearing. The yarn-dyed production process has also been continuously improved, innovated and perfected in the course of its development. At present, the preparation process of mid-weft yarn in yarn-dyed production is: bobbin in yarn factory-loose yarn-dyeing-winding-weaving. The winding process after dyeing yarn is a traditional process in the yarn-dyed production process. The yarn bobbin with small taper is wound into a large tapered cone yarn with suitable density and good shape for weaving weft insertion. However, after the yarn is wound, due to severe friction, the neps and thick places increase greatly, and the evenness, fine details and hairiness ...
