Abstract: A laminate is made by first making by melt-blowing or spunbonding of multicomponent, thermoplastic, and endless filaments a first nonwoven layer lying generally in a plane and having a predetermined shrinkage capacity or potential parallel to the plane and making of thermoplastic and endless filaments a second nonwoven layer also lying generally in a respective plane and having a shrinkage capacity or potential that is smaller than that of the first nonwoven layer.

Abstract: A product and process of manufacturing a non-woven web from cotton regin for use as an industrial hydrophobic absorbent, a filter or insulator. The method of processing the cotton regin creates a low-density and, thus, a high-absorbency web. The finished web has a bulk-to-weight ratio of about 25 to 40 mils/osy.
