Study on wrinkle free finish on 100% cotton fabric

摘要

The term easy care means that a fabric does not crease during use and any crease after washing is easily removed from the fabric. Cotton fabric are very comfortable to wear because of their good natural properties, but during drying after washing they shows dimensional variations that impart shrinkage to the fabric. Creasing of cotton fabrics depends on structural properties of the fiber. Now a days, crease resistance is obtained by easy care finishing which stiffens the cotton fibers by covalent cross linking and therefore, resistance to bending creasing and recovery from deformation can be promoted. The process mainly consists of cross linking of cotton fibre hydroxyl group with a cross linking agent; the possibilities of displacement of fibre chain molecules decreases. It has been demonstrated that the degree of cross linking has a profound effect on the crease recovery angle and the dimensional stability of cotton fabric.
