Which parts of the warp knitting machine are mainly composed of

A knitting machine that weaves parallel warp threads into warp knitted fabric. Warp knitting machine appeared earlier, in 1775, the British J. Crane invented the first single comb crochet warp knitting machine. There are many kinds of warp knitting machines, and according to the structural characteristics, there are mainly two categories: Tricot type and Raschel type. In Tricot warp knitting machine, the Angle between the fabric drawn by the knitting needle and the plane of the needle bar is about 115°, and the fabric is pulled by the settler and the pull roller together, so that the newly formed coil turns to the back of the needle and leaves the knitting area.

Therefore, the pattern design can be quickly and arbitrarily carried out without restriction, and the machine speed can be increased to 1100 RPM, which is difficult to achieve in the past. In order to further increase the machine speed, the machine can be configured into 3 comb bars (RSJ3/1), so that the machine speed can reach 1300 RPM. In addition, the machine number is up to E32. The speed and size of the current Piai Jaca machines are unimaginable with traditional Jaca technology.

At present, the warp knitting machine industry is in a downturn in the development period, coupled with the pressure of capital and other aspects, the development confidence of some downstream enterprises has been hit, they have basically shelved the expansion of the plan, resulting in the lack of overall market demand and desire. From the current market situation, the total sales of warp knitting machines this year showed a downward trend, but the warp knitting equipment such as multi-axial, raschel and so on, which can be used in construction, aviation, automobiles and other fields, the application space is relatively large, so it also has a larger market competitiveness.
