Abstract
The invention relates to variable-weft-density warp rib fabric and a production method thereof. The variable-weft-density warp rib fabric is characterized in that the variable-weft-density warp rib fabric is a warp rib fabric with two different weft densities changing alternately. The production method mainly comprises the following steps of (1) weft yarn preparation and (2) weaving, wherein in the step (1), according to the number of weave points of the fabric, single-yarn bobbins are processed into multiple-yarn bobbins with the number the same as that of the same type of continuous weave points on the fabric, and in the step (2), weaving is realized on a multi-color weft selection weaving machine without a weft density changing function. During weaving, in shed opening every time, according to the weft insertion order set according to the weft density changing rules, a weft insertion mechanism inserts single yarns and stranded yarns into corresponding sheds alternately, a warp pacing mechanism sends out a constant length of warp, a rolling mechanism rolls a constant length of fabric, and therefore weaving of the variable-weft-density warp rib fabric is realized. The variable-weft-density warp rib fabric and the production method of the variable-weft-density warp rib fabric have the advantages that the weaving method is simple, repeated investment is not needed, the range of fabrics capable of being produced and woven by the existing weaving machine without the weft density changing function can be widened and the yield of the weaving machine can also be increased.
