Relationship between Creasing-Recovery Force and Crease-Recovery Angle

To find out the reason of resulting in the crease recovery of a fabric and provide theoretical guidance for designing a new material with good creasing-recovery property, the relationship between the creasing-recovery force and the crease-recovery angle of a woven fabric was investigated by self-setup experimental device. The results show that the crease-recovery angle of a woven fabric is correlated with the creasing-recovery force of the fabric in a linear relation. Furthermore, it is found that the internal stress is the principal force of affecting the creasing-recovery property of a woven fabric. In addition, the relatiouship between the tensile property of a woven fabric and the creasing-recovery property of the fabric has also been investigated, showing that the lower relaxation velocity of tensile stress of a fabric is, the better creasing-recovery property of the fabric has.
