ABSTRACT:
A plurality of synthetic fibrous textile materials such as polymeric yarns and staple fibers are textured by a procedure which imparts a variety of spaced deformations in a random sequence. The fibrous textile materials are fed between two opposed pressure surfaces, one of which has a raised pattern of closely spaced pyramids while the other is made of a resilient material having a meshing pattern of pyramid shaped depressions. The textile material is maintained at an elevated temperature during its passage between the pressure surfaces and is then cooled to give a permanently textured product.
