Textile shrinkage is shrinkage percentage of textile after being washed or soaked. Generally, synthetic fiber and other blended fabrics have the highest shrinkage percentage. Wool fabric, hemp fabrics and cotton fabric are the next.
Factors for textile shrinkage
Various raw materials cause different textile shrinkage. For fibers having good hygroscopicity, fibers inflate, diameter increasing and length decreasing after soaking. So fibers have high textile shrinkage. For example, water absorption of viscose fibers is high as 13%. While synthetic fiber has low shrinkage for its bad hygroscopicity.
Different density cause different textile shrinkage. For example, when density of warp is close to weft, their shrinkage is quite similar. When density of weft is higher warp, textile has high shrinkage.
Roughness is a factor for shrinkage. If yarns have high roughness, textile has low shrinkage.
Different production processes can also cause different shrinkage. During knitting and dying, textile has high shrinkage if fibers are drawn for several times and have long processing time.
