Fabric shrinkage refers to the percentage of fabric shrinkage after washing or soaking. Generally speaking, the fabrics with larger shrinkage are synthetic and fiber structure and their blended fabrics, followed by wool fabrics and hemp fabrics, cotton fabrics are in the middle with larger shrinkage, while viscose, rayon and artificial wool fabrics are the larger ones. Do you know the cause of fabric shrinkage? Let's follow the textile weaving to understand it!

1. Fabric shrinkage is different with different raw materials. Generally speaking, the fiber with high hygroscopicity will expand after soaking, the diameter can be large, the length can be shortened, and the shrinkage will be large. For example, some viscose fibers have water absorption as high as 13%, but synthetic research fiber fabric has poor hygroscopicity, and its shrinkage is small.

2. The shrinkage of fabric is different with different density. If the longitudinal and latitudinal densities are similar, the longitudinal and latitudinal shrinkage is also close. The fabric with high warp density will shrink more in warp direction. On the contrary, if the weft density is greater than warp density, the weft shrinkage will be greater.

3. The shrinkage is different with different yarn thickness. The shrinkage of thick fabric is larger than that of fine fabric.

4. The shrinkage of fabric varies with the production process. Generally speaking, in the process of weaving, dyeing and finishing, the fiber has to be stretched many times, and the processing time is long. If the tension is large, the shrinkage of the fabric will be large, otherwise it will be small.
