Shrinkage is the contraction in the dimension of the fabric due to usage. These are the reasons for shrinkage: • In case of a fabric‚ the warp yarns are under much strain due to interlacement than the weft yarns. Hence when a fabric is allowed to shrink‚ the warp yarn shrinkage will be more than weft yarns. • To overcome this fabric is extended in widthwise to some extent in the stenter machine during the finishing process. Then it is subjected to the preshrink process. Various mechanical
