Looms that have traditionally been woven using yarns can be divided into two major categories, woven and knitted. The looms include the original shuttle looms and the new shuttleless looms. The shuttleless looms mainly include rapier looms, air jet looms, water jet looms and projectile looms. Knitting machines are divided into two major categories, warp knitting and weft knitting, and there are many small classifications under them.
In the knitting category, the development of China's weaving machinery products is uneven. Among them, the circular weft knitting machine and the warp knitting machine are developing rapidly, the flat knitting machine and the sock knitting machine are relatively slow, and the crochet knitting machine develops rapidly. The basic products used in domestic circular weft knitting machines are quite complete, and there are single-sided, double-sided circular weft knitting machines, rib knitting machines and artificial fur machines. There are four needles, loops (positive and reverse), weft insertion, multi-function single-sided machine, etc. in the single-sided circular weft.
The diameter of the cylinder has been developed to a maximum of 38 to 40 inches on the basis of the usual 30 inches. The machine number has also evolved from the fine pitch E28 to E32 to E36. The double-sided circular weft machine has a cotton machine, two upper and lower four sections. Double-sided machine, jacquard double-sided machine, etc.; rib machine has its own series, cotton machine and rib machine can realize mutual conversion; electronic jacquard circular weft machine has made a breakthrough, filling the gap in China; artificial fur machine has top feeding type And the cut loop type, the computer jacquard artificial fur machine has been produced in batches.
Woven can be divided into two categories: shuttle looms and shuttleless looms according to the weft insertion method. Woven fabrics using the traditional shuttle (plastic or wood shuttle hook) weft insertion loom. Shuttle bulky, heavy, repeated exchanges is projected, a large machine vibration, high noise, vehicle speed slow, inefficient. Shuttleless loom weft insertion is varied, rapier, injection (jet, water), a gripper, a multi-shed (heterogeneous) and weaving the like.
