Background
In the using process of the fabric, due to the action of mechanical external force such as rolling, friction, washing and the like, molecular chains in a fiber macromolecule amorphous region move, the rearrangement of molecules is re-fixed by intermolecular force formed between adjacent groups, and finally, a serious wrinkle phenomenon is caused. Thus, there is a need for crease-resistant finishing of fabrics to improve additional properties of the fabric. However, the problem of yellowing of crease-resistant finished fabrics has severely hampered the widespread use of various crease-resistant finishing agents, especially the environmentally friendly cross-linking of citric acid.
