Optimum design of weft-curve fabric based on difference of shrinkage

In order to solve the problem that weaving normal curve fabric needs special mechanical equipment,the curve effect forming mechanism of weft-curve fabric was studied from the aspects of different weaves,color area matching and the arrangement of color yarn. The relationship of fundamental parameters and process factors was analyzed and optimally designed by orthogonal test and weaving of fabrics. It has been proved that weave and weft density have great influence on the curving rate. The optimum process is A1B1C3,i. e. under conditions of plain weave,reed number of 157. 5 /10 cm and weft density of 295 /10 cm,the maximum curving rate is obtained,and the curve effect is optimized,thereby realizing unique natural weft effect. The result can be used in the design of various cotton,silk and wool fabrics.
