Abstract
A continuous process of making a blended yarn of staple fiber and long-fiber or filamentary material in which the long-fiber or filamentary material is passed through a rupture zone to produce lengths thereof which are fed directly into an air stream with the staple fibers to produce an intimate blend which is conveyed by the air stream directly to an open end spinning device which produces the yarn.
Claims11
A continuous process for forming blended yarn from long-fiber or filamentary activated carbon and staple fiber including the steps of passing the long-fiber or filamentary activated carbon through a rupture zone, reducing the long-fiber or filamentary activated carbon to shorter lengths in said rupture zone, passing said shorter lengths of activated carbon directly into an air stream leading from said rupture zone to a fiber collection zone, introducing staple fibers into said air stream with said shorter lengths of activated carbon, maintaining said staple fibers and said shorter lengths of activated carbon in said air stream for a sufficiently long time to result in an intimate blend of staple fibers and activated carbon shorter lengths in said collection zone and continuously spinning said blend to produce said yarn.
