Document Summary

Is a reduction in length or wight of a fiber, yarn, fabric. Woven fabric is stable than knit fabric. Wool , cotton and rayona tend to shrink the most. Diametion = testing the fabric possible shrinkage relaxation shrinkage. Wary yarn =high tension in loom shrink when realax. Dry cleaning= solvent, dont shrink too much(seam can cause the shrink) Steaming during pressing could cause shrinkage progressing shrinkage. Occurs every time a fabric is laundered. Problem with wool and viscose rayon controlling shrinkage. Compacting the fabric: overfeeding the fabric between rollers to induce lengthwise shrinkage. Poly can added to cotton to enable heat setting compressive shrinkage. Moist fabric laid over thick felt cloth, passed around a afeed in a roll. Outer surface stretches and the inner surface contracts. The blanket layer the nreverses to target opposite side. Fabric against the drum dried &set w/ smooth finish in crease fabric count. Fabrics kept under press for 12 hrs.
