  • Publication number: 20140224374
    Abstract: A weave of composite material has a first weave and an X weave combined with the first weave. The X weave has multiple latitudinal fibers, multiple longitudinal fibers, and a woven center. Each longitudinal fiber is layered on two of the latitudinal fibers and then is woven through and layered under two of the latitudinal fibers. The longitudinal fibers are each woven by shifting in relative alignment position from one of the latitudinal fibers sequentially and woven radially with respect to a woven center, such that the longitudinal fibers form an X woven structure. Therefore, the intensity of the weave of composite material can be enhanced by the X weave with the X woven structure.

    Abstract: A fabric which contains warp threads made of a delicate material is produced on a loom which includes a main reed and auxiliary end reeds at opposite ends of the main reed and which are independently operable with respect to the main reed. The warp threads made of delicate material are extended through the main reed and warp threads of a more robust material are extended through the auxiliary end reeds. As each filler (weft) thread is inserted in a shed the auxiliary end reeds are moved to beat the associated portions of the weft threads. Only after a plurality of weft threads have been inserted is the main reed moved to beat the associated portion of the weft threads, thereby reducing the frequency of movement between the dents of the main reed and the delicate warp threads and thereby reducing frictional destruction thereof.
