Abstract:

In actual production process, due to the special action of a single yarn selection device, largearea yarn breaking easily occurs in novel process of warp knitted borché fabrics while in startup, hence, the reason why yarns are easily broken during starting-up course weaving is introduced in detail, and an effective solution is proposed by using borché preparation process to nake preparation for the pattern production. Specifically, before the new warp knitted machine works, the prepared technical pattern is firstly preformed, and then pattern production is performed, and the broche preparation process is integrated in the Jacquard controller device. The results show that this solution can not only ensure the smooth operation of weaving, and can meet the fabric face quality required by the production. The design principle of the broche preparation process is proposed, and illustrated by examples.
