Abstract
The contraction properties of woven fabric are one of the major parameters that significantly depend on the weave structure of a fabric. It is well established that the contraction of yarns changes with changing the interlacement sequence or the weave structure. The comparative analysis and justification of warp contractions for different weave structures are studied in this research work. Eighty type fabrics with varying weave structure are carefully chosen and the average contraction factors are determined and compared with each other. The study found a significant variation of contraction among the weave structures. The plain weave showed the highest contraction factor and satin showed the lowest. But, for a few intermediate results especially of the derivatives of twill and matt fabrics, the variation of contraction factor cannot be explained by interlacement sequences only as the final packing of fabric after relaxation depend on several other factors which are also explained with relevant literatures. Some exception results are also experienced by very few fabric types.
