Fabric shrinkage deformation in the dyeing and finishing process fabric in the weaving and dyeing process usually warps to bear muscular mechanical tension, resulting in the fabric weft door contraction and warp elongation of the unstable state. After the fabric is dipped and rolled, the length that produces different degrees of contraction and washing will continue to have a subsequent contraction. Such as this fabric tailoring clothing, once passed, due to fabric shrinkage and clothing deformation out of shape, causing significant losses to consumers. The best solution is to reduce the mechanical tension in the process. The choice of tension-free loose automated processing, from spinning, and weaving to printing and dyeing processing, a series of operations to fully meet this requirement, is also impractical.

Measures to improve fabric shrinkage

The current measures are taken: is the end of the dyeing and finishing process, trying to make the warp yarn of the fabric have the opportunity to shrink back to restore the balance of the yarn bending state, to achieve the purpose of reducing shrinkage later.

So to make the fabric through mechanical action and the form of stable, non-deformation is a very significant economic significance of the work. This finishing method is called mechanical pre-shrinkage finishing, and the equipment it uses is the sanforizer (or called shrinking range)
