1. Fabric shrinkage
The shrinkage of the fabric refers to the percentage of fabric shrinkage after the fabric is washed or soaked. In general, the fabric with the largest shrinkage rate is synthetic fiber and its mixed textiles, followed by wool, hemp fabric, cotton fabric centered, shrinking water, and the largest is viscose fiber, rayon, artificial wool fabric.
2. The factors that cause the fabric to shrink:
1 The raw materials of the fabric are different and the shrinkage rate is different. In general, a fiber having a large hygroscopic property expands after immersion in water, has an increased diameter, a shortened length, and a large shrinkage rate. If the viscose fiber has a water absorption rate as high as 13%, and the synthetic fiber fabric has poor hygroscopicity, the shrinkage rate is small.
2 The density of the fabric is different and the shrinkage rate is also different. If the latitude and longitude density are similar, the warp and weft shrinkage rate is also close. The fabric with a high density has a large shrinkage in the warp direction. On the contrary, the weft density is larger than that of the dense fabric, and the weft shrinkage is also large.
3 The thickness of the fabric yarn is different, and the shrinkage rate is also different. The shrinkage rate of the coarse yarn is large, and the shrinkage of the fine fabric is small.
4 The fabric production process is different, and the shrinkage rate is also different. Generally, in the weaving and dyeing process of the fabric, the fiber is stretched many times, the processing time is long, and the shrinkage rate of the fabric with a large applied tension is large, and vice versa.
