Evenness Control of Rapier Loom Tension by Using Neural Network

The neural network model （NNM） is used to control the evenness of rapier loom tension and to model the uncertain parameters of drafting process. This model can estimate recursively the tension and incorporate predictive control strategies. After controlling the effect testing, it can be seen that the behavior is excellent following different set point and variations, such as the diameter of the beam of weaver, air stream, density of warp and weft, type of textile, etc. An optimum steady state scheme has been fixed in keeping evenness of tension of loom. This method improves obviously the efficiency and quality of production.

Principle and Method for Structural Design of Digital Woven Fabric

IntroductionThe structural design of woven fabric is realized byinterlacement .In woven fabric ,the warp and weft threadsinterweave with each other . This rule of interlacement iscalled weave[1]. The fabric s appearance and mechanicalproperty change along with the fabric construction ofweaves . Any weave is composed by warp and weftinterlacing points alternately . The number of threadsrequired whenever the arrangement of the warp and weftinterlacing points repeats for one ti me is called a we…
