Introduction
Creases in textile fabrics diminish at varying rates on the removal of the creasing forces. The magnitude
of the crease recovery angle is an indication of the ability of a fabric to recover from accidental creasing.
ISO 2313 consists of two parts:
— Part 1 specifies a method for measuring crease recovery angle for rectangular fabric specimen,
while placing it in such a way that the folded line is parallel to horizontal plane; and
— Part 2 specifies a method for measuring crease recovery angle of convex-shaped fabric specimen,
while placing it in such a way that the folded line is vertical to horizontal plane.
The suitable method can be chosen according to the type or end-use of textile fabrics. The test results
