Different fabrics have different shrinkage rates. Generally speaking, for fibers with high moisture absorption, after being immersed in water, the fiber expands, its diameter increases, its length decreases, and its shrinkage rate are large.

The density of the fabric is different, the shrinkage rate is also different. Fabrics with a high warp density will shrink in the warp direction. Conversely, fabrics with a weft density greater than the warp density will shrink in the weft direction.

Different fabric yarn counts have different shrinkage rates. The shrinkage rate of fabrics with thick yarn counts is large, and the shrinkage rate of fabrics with fine yarn counts is small.

Different fabric production processes have different shrinkage rates. Generally speaking, in the process of weaving, dyeing and finishing the fabric, the fiber has to be stretched many times, and the processing time is long. The shrinkage rate of the fabric with greater applied tension is greater, and vice versa.

The fiber composition is different, the shrinkage rate is also different. Compared with synthetic fibers, natural plant fibers and plant regenerated fibers are easier to absorb moisture and swell, so the shrinkage rate is larger, while wool is easily felted due to the scale structure on the fiber surface, which affects its dimensional stability.

The fabric structure is different, the shrinkage rate is also different. In general, the dimensional stability of woven fabrics is better than that of knitted fabrics, and the dimensional stability of high-density fabrics is better than that of low-density fabrics.

Different production processes have different shrinkage rates. As the fabric is inevitably stretched by the machine during the process of dyeing, printing and finishing, there is tension on the fabric. However, the tension of the fabric is easily released when it meets water, so we will find that the fabric shrinks after washing.

The washing and care process is different, the shrinkage rate is also different. Washing care includes washing, drying, and ironing. Each of these three steps will affect the shrinkage of the fabric. The washing temperature also affects its dimensional stability. Generally speaking, the higher the temperature, the worse the stability.

The drying method of the fabric has a relatively large impact on the shrinkage of the fabric. Among them, the drip drying method has the least impact on the size of the fabric, while the drum arch drying method has the greatest impact on the size of the fabric.

In addition, choosing an appropriate ironing temperature according to the composition of the fabric can also improve the shrinkage of the fabric.
