ABSTRACT:
Non-woven articles, including garments and porous sheet materials, are made from continuous filaments by ejecting continuous yarn or filaments into turbulent air and contacting them with binder in a high density fog while still suspended in air, so that the binder dries sufficiently to become non-migrating before the yarn is 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.
