Description

Technical Field

[0001] The utility model relates to the technical field of water jet looms, in particular to a rear beam mechanism of a water jet loom. Background Art

[0002] The frictional traction of water jet weft insertion on the warp yarn is greater than that of air jet weft insertion, and its diffusion is small. It is suitable for the weft insertion of smooth-surfaced synthetic fibers, glass fibers and other filaments. At the same time, it can increase the conductivity of synthetic fibers and effectively overcome static electricity in weaving. In addition, jetting warp yarn consumes less energy and has the lowest noise.
