Abstract
Air-laid fibrous webs are formed from randomly-oriented mixed fibers containing a minor proportion of short, flock-length, thermoplastic and thermoretractile fibers. The air-laid web is then heated, without pressure, to cause melting of the thermoplastic fibers to the point of substantially complete loss of fiber identity. The relative orientation of the web thus formed is stabilized so that the fibers therein maintain their general positional relationships through subsequent stresses incurred during the operations of printing, saturating, drying, winding into roll form and the like.
