Bagging in Textiles

Abstract

Abstract Bagging is a three-dimensional residual deformation, seen in used garments, which causes a deterioration in the appearance of the garment. The places it is seen during wear are elbows, knees, pockets, hips, and heels. The common factor in all of these parts of garments is the force exerted on that area of the fabric from the moving parts of the body. When the fabric covering that part of the body feels this force for a long time and feels it repeatedly, the fabric deforms and starts to take the form the force is trying to give to it. The force coming from the human body is in the transverse direction to the fabric's plane and the deformation which occurs is spatial. This prolonged and repeated deformation causes the fabric to change its shape, and it usually takes a dome shape, like a part of a sphere, so it is a three dimensional complex deformation that is very different from the other kinds of deformation seen in textile materials.
