A method and system for forming composite yarns having selected performance characteristics including cut resistance and/or fire/heat resistance. The composite yarn will include a core of one or more filaments and a fiber bundle wrapped about the core and integrated with one or more additional filaments that help bind the fibers about the core. An additional filament or other composite yarn can be plied together therewith to form the finished composite yarn. The core filament(s) will be selected from cut and/or fire/heat resistant materials, while the fibers of the fiber bundle and the additional filament(s) wrapped about the core can be selected from natural or synthetic fibers or filaments having additional desired properties.

A process for manufacturing a bonded fabric for high performance industrial belts is provided. The process includes providing a base fabric made up of warp yarns provided with a predetermined elasticity and weft yarns provided with a lower elasticity than the warp yarns, and subjecting the base fabric to a bonding treatment.

A surface-colored glass cloth including a glass cloth which includes a warp and a weft and a plurality of colored portions which are attached to a surface of the glass cloth is disclosed. One colored portion is disposed in each area including one colored point. An average distance D between the adjacent colored points is 0.50 to 10.00 mm. When the number of warp rows is St, a warp widening degree is Et, the number of weft rows is Sy, and a weft widening degree is Ey in the glass cloth, D, St, Et, Sy, and Ey satisfy a formula: 3.3≤100×D.sup.1/2×(Et×Ey)/(St×Sy)≤25.0.

A fibrous texture has the shape of a strip extending in a longitudinal direction over a determined length between a proximal portion and a distal portion and in a lateral direction over a determined width between a first lateral edge and a second lateral edge. The fibrous texture has a three-dimensional or multi-layer weaving between a plurality of layers of warp strands extending in the longitudinal direction and a plurality of layers of weft strands extending in the lateral direction, the fibrous texture including first and second longitudinal sections extending over a width from the first or second lateral edge smaller than the determined width of the fibrous texture along the lateral direction. The first and second longitudinal sections each include warp strands and weft strands constituted by carbon fibers. The fibrous texture further includes a third section present between the first and second sections.
