Textile Tips: Analysis of Common Fabric Shrinkage and Causes

The phenomenon that the yarn length of the textile fabric changes after being exposed to water, and the shrinkage rate of the fabric refers to the percentage of shrinkage of the fabric after the fabric is washed or soaked. The shrinkage of conventional fabrics varies in size. Let's take a look. What is the shrinkage value of general fabrics?

1, the shrinkage of textile fabrics

True white cloth 3%;

Blue cloth 3-4%;

å“—å½ 3-4%;

Poplin 3-4.5%;

Floral cloth 3-3.5%;

Cotton polyester 3.5% - 55%;

Twill 4%;

Cathy Huada 4-5.5;

Cotton 4% - 10%;

Chemical fiber 4%--8%;

Labor cloth 10%;

Rayon 10%.

2, the fabric shrinkage factors:

1 The raw materials of the fabric are different, and the shrinkage rate is different. In general, fibers with high hygroscopicity undergo fiber swelling after immersion in water, the diameter increases, the length decreases, and the shrinkage rate increases. For example, the viscose fiber has a water absorption rate as high as 13%, and the synthetic fiber fabric has poor hygroscopicity, and its shrinkage rate is small.

2 The density of the fabric is different, and the shrinkage rate is also different. If the warp and weft density is similar, the warp and weft shrinkage is also close. After the density of the fabric, the warp shrinkage is large, on the contrary, the weft density is greater than the dense fabric, the weft shrinkage is also large.

3 The thickness of the fabric yarn is different, and the shrinkage rate is also different. The coarse cloth shrinkage of the yarn is large, and the fabric shrinkage of the fine yarn is small.

4 different fabric production process, the shrinkage rate is also different. In general, in the process of weaving and dyeing, the fabric has to be stretched many times, the processing time is long, and the shrinkage of the fabric with greater tension is larger, and vice versa.
