The purpose and process of wire doubling
After selecting the specifications of the raw materials, the raw materials with the required properties must be sorted according to the design requirements for weaving. The arrangement method of warp and weft threads formulated according to the design intention is called linear design. Linear design is achieved through doubling and twisting processes. During the finishing process, the linear density, twist, twist direction, tension, etc. of the silk thread (or spinning yarn) are constantly changed to improve its performance, increase strength and elasticity, and moderately change the winding shape of the silk thread to achieve the design Purpose. 1. The purpose of doubling yarns is to play an important role in improving fabric quality. Silk fabric materials produced according to certain specifications are far from meeting the needs of process design. If the commonly used silk specifications cannot meet the quality requirements of the fabric, several warp threads need to be combined. The doubling process should be adopted in the following situations: (1) When the fabric quality requirements cannot be solved by increasing density. (2) When the linear density of the selected raw materials is uniform. (3) Two or more raw materials need to be laminated for warp or weft. (4) For fabrics with more than two wefts, the wefts need to be full and raised, and have a sense of relief.
