Problems solved by technology

[0003] The overall warp density of the double-layer fabric is high, and the opening is not easy to be clear. If the air-jet loom is used to weave, the weft stop is relatively high, and the weft yarn has 5 colors. The weft yarn color selection function of the air-jet loom is far inferior to that of the rapier weaving Machine, can not give full play to the performance of the fast speed of the air-jet loom
However, if the Schmidt high-speed rapier loom is used, there will be more faults

Abstract

The invention discloses a production technology for all-cotton yarn-dyed weaving surface and inner layer exchange dobby. The technology comprises a spooling process, a warping-sizing process, a drawing-in process and a weaving process. According to the production technology, a warping-sizing combined technology is adopted, the stability of the sizing percentage can be guaranteed through low-temperature sizing, and a sizing agent which is low in polymerization degree and low in viscosity is mainly used as the sizing agent for low-temperature sizing; the technology of being low in loom speed, early for opening, late for rapier feeding and low in back rest is adopted by a loom, and thus conditions are created for improving the quality of the product and the production efficiency of the loom. After the measures are taken, the problems emerging in the production process are well solved, and good economic benefits are achieved.

Description

technical field [0001] The invention specifically relates to a production process of an all-cotton yarn-dyed dobby jacquard fabric with outer and inner layers. Background technique [0002] The outer and inner layer of the fabric is to exchange the surface layer and the inner layer of the fabric up and down according to the requirements of the pattern to form a pattern. The warp and weft yarn materials and colors of the outer and inner layer fabrics can be matched according to needs. The warp and weft yarns of different colors can weave colorful patterns. [0003] The overall warp density of the double-layer fabric is relatively high, and the opening is not easy to be clear. If the air-jet loom is used for weaving, the weft stop is relatively high, and the weft yarn has 5 colors. The weft yarn color selection function of the air-jet loom is far inferior to that of the rapier weaving machine machine, can not give full play to the performance of the fast speed of the air-jet ...
