Bending

The performance of any textile structure under most service conditions depends to a great extent on its bending behavior. The importance of the bending behavior is apparent in the folding of sleeping bags or the billowing of tents or for the apparels in the parts like knee, elbow, sleeves etc. In other words, the bending occurs in those areas where different forces (by direction as well as by value) are applied to the same area of the product.

The bending behavior is expressed in terms of bending rigidity (also known as flexural rigidity) which provides you with a measure of ease with which the fabric bends. The fabric's flexural rigidity basically depends on the constituent fibers and yarns from which the fabric is manufactured, the fabric construction and most importantly the nature of the chemical treatment given to the fabric.
