Abstract
A weave-de-weave process in which a plurality of weft loops are fluidly injected from opposite sides and normal to a plurality of warp yarns to form a composite tape. The tape is deweaved after the warp is space dyed by splitting the interior of the tape to expose the looped ends of the weft.
Claims7
In a weave-de-weave process in which weft is inserted in a direction normal to a plurality of warp yarns to stabilize the warp by forming a composite tape, and then after treatment of the yarns on the tape, the weft is removed to deweave the tape and the warp is packaged, the improvement comprising the steps of:
- fluidly injecting said weft between said warp yarns alternately from opposite sides of said warp in continuous, spaced loops;
- laterally splitting the interior of said tape generally parallel to said warp yarns into a plurality of tapes, exposing the looped ends of said weft intermediate the tapes and
- stripping the weft continuously from said warp to deweave said tapes by
- successively gripping the exposed looped ends of said weft and pulling said weft from between said warp.
