Abstract: This invention deals with nonwoven articles made from continuous filaments, including garments and porous sheet materials. In the past, nonwoven products have suffered the handicap of a stiff and ''''boardy'''' feel. We eject continuous yarn or filaments in an air space and contact them with binder droplets while still suspended in air, so that the droplets dry sufficiently to become nonmigrating before they are deposited on the screen or mold on which the fibers are brought into contact with each other and bonding takes place. This method is particularly suitable for making garments of elastomeric fibers, not easily handled in ordinary production machinery. Another generally applicable advantage is that the resultant products are exceptionally flexible and that the articles produced do not split into stratified binder-rich and -poor areas, but are uniformly bonded throughout.
