Fabric shrinkage is a phenomenon in which the size or shape of a fabric changes during the washing or laundering process. Factors influencing fabric shrinkage include:

In addition, textile fibres are subjected to heat conditions, the form and size of the fibres change and shrink, and cannot return to their initial state after cooling down, known as thermal shrinkage of fibres. For example, the boiling water shrinkage rate of processing polyester staple fiber is 1%, vinylon boiling water shrinkage rate of 5%, chlorine spandex hot air shrinkage rate of 50%. Heat shrinkage, mainly in polyester nylon, a thermoplastic chemical fibre above, is improved by good heat setting during dyeing and finishing, making it possible to obtain good dimensional stability through high temperature setting.

In order to improve the problem of fabric shrinkage, the following measures can be used:


1. use high quality fibre raw materials, such as long-staple cotton, mulberry silk, etc., in order to improve the dimensional stability of the fabric.


2. Use a more compact fabric structure to reduce the amount of shrinkage of the fabric.
