The main longitude and latitude lines are not intersected with each other, the latitude lines are on both sides of the main longitude line, connected by the warp knitting line. Because the warp and weft lines are arranged in a straight line, non-shrinkage, therefore, the strength efficiency of the fibers, i.e. the strength retention rate of the fibers after weaving into the fabric, is very high, the dimensional stability of the fabric is good.
The straight-warp and straight-weft conveyor belt is a kind of fabric with different structure from canvas. Its warp and weft lines are in different layers and are not interwoven, because the warp and weft lines are in a straight state, without shrinkage, and the strength efficiency of the warp and weft lines is the highest. This kind of fabric is composed of three layers, the middle layer is the warp, the upper and lower layers are the weft, and the warp and weft of each layer are linked together by suspender to form the fabric as a whole.
