Basic knowledge of special-shaped reeds for water jet loom accessories

The special-shaped reed of the accessories of the water jet loom is an important part of weft insertion and beating-up in the weaving process. Its service life and operating status are directly related to the efficiency of the loom and the quality of the fabric. With the extension of the operating time of the special-shaped reed machine, wear and damage are gradually increasing. How to use and maintain the special-shaped reed correctly, extend its use time or maintenance cycle, and reduce maintenance costs is particularly important. Through many years of production practice, it has been found that the damage of the special-shaped reeds is mostly caused by the wear of the side reeds, that is, the so-called yarn groove; a few are damaged due to improper operation, use or storage. The following introduces the common sense of special-shaped reeds for water jet loom accessories:
(1) The role of alien reeds. Arrangement function: arrange the warp yarns according to the requirements of the fabric; weft insertion function: weft insertion through the air slot; beating-up function: drive the weft yarn into the weaving mouth.
(2) The basic parameter of the special-shaped reed is the reed number, which refers to the number of reed teeth per unit length.
(3) Representation method of special-shaped reed specifications: box number*full length*outer height, such as 84.25/5.08cm*20858*122, which means that the reed number is 84.25/5.08cm, the reed length is 2085 mm, and the reed height is 122mm. Special-shaped reeds, where 84.25/5.08cm means that there are 84.25 reeds in a length of 5.08cm.
The water jet loom is suitable for the weft insertion of filaments with smooth surface such as synthetic fiber and glass fiber. At the same time, it can increase the conductivity of synthetic fibers and effectively overcome static electricity in weaving. In addition, jetting the weft yarn consumes less energy and has the lowest noise.
