Definition of Shrinkage

Shrinkage refers to the change indicators of the fabric size after the washing and drying and it is one of the most important fabric wearability. The strength of shrinkage has a great influence on the garment or other textile products specifications. In the process of cutting garment material, especially two or more fabrics commissure are being tailored,wholesale fabric supplier must take these factors into account to ensure that the specifications and wearing requirements. The several following major factors can affect the fabric shrinkage.

Fiber Components of Fabric
Compared with synthetic fibers (polyester, acrylic), natural plant fibers (such as cotton, linen) and plant regeneration fibers (viscose) are easily hygroscopic and expand, therefore the shrinkage is larger. While the scale structure of wool easily affects its dimensional stability.

The Structure of Fabric
Under normal circumstances, the dimensional stability of the woven fabric is superior to the knitted fabric; the dimensional stability of the high-density fabric is superior to a low density, such as the stability of denim fabric is higher. In the dryer fabric, the shrinkage of the general plain weave fabric is smaller than a flannel fabric; knitted fabric the plain stitch shrinkage is smaller than rib fabric.

Production Process of Fabric
In dyeing, printing and finishing process, fabrics is inevitably stretched by machine and the tension exists in the fabric. While fabric easily relieves tension when encounter with water, so we find that the fabric has shrunk in the wash after. In the actual process, we generally use pre-shrunk to solve this problem.

The Process of Washing and Maintaining
Wash care includes washing, drying and ironing, and every step of the three steps will affect the fabric shrinking. E.g. the dimensional stability of the handwash sample is superior to the samples of the machine wash and the washing temperature will also affect the dimensional stability. Generally, the higher the temperature is, the worse the stability is. The drying of the sample on the fabric impacts the shrinkage a lot. There are four common ways of drying: drip-drying method, metal mesh tiling method, hang dry drying and drum drying method. The drip-drying method has the minimum impact on the fabric, and the drum drying method has greatest impact on the size of the fabric. In addition, selecting an appropriate ironing temperature based on the composition of the fabric can also improve the fabric shrinking. For example, cotton and linen fabrics can improve its size shrinkage by hot iron. But not the higher the temperature, the better for synthetic fibers, because high temperature ironing cannot improve its shrinkage, but its performance will have destruction, such as the fabric stiff crisp. Therefore reasonable care label is very important to wash their clothes.
