The invention addresses the problem of providing a cloth and a protective product that have lightweight properties, wearing comfort, and further protection performance against electric arcs. A means for resolution is a cloth including a spun yarn containing a meta-type wholly aromatic polyamide fiber, wherein the cloth has a lightness index L-value of 25 or less.

A composite yarn. The composite yarn has a glass core having a linear weight ranging between 50 to 400 deniers and composing from 15 to 60% of a total linear weight of the composite yarn. The composite yarn has a sheath surrounding the glass core, where the sheath is constituted at least of fibers of meta-aramid. The sheath constitutes a remainder of the total linear weight of the composite yarn. The composite yarn has a yarn count between 10 tex and 80 tex.

A heat resistant separation fabric for use as tool covering in the production of glass products at temperatures over 580° C., wherein the heat resistant separation fabric comprises fiber yarns, and wherein said fiber yarns comprise metal fibers out of first material containing: 18 to 21 weight percent Cr, 23 to 26 weight percent Ni, 5.5 to 7 weight percent Mo, and 40 to 50 weight percent Fe.

The invention addresses the problem of providing a cloth that is excellent not only in flame retardancy and antistatic properties but also in appearance quality and preferably also has protection performance against electric arcs, a method for producing the same, and a textile product. A means for resolution is a cloth including a meta-type wholly aromatic polyamide fiber and an electrically conductive fiber, wherein both the meta-type wholly aromatic polyamide fiber and the electrically conductive fiber are colored.

A flame resistant knit fabric having a first weft yarn set and a second weft yarn set. The first weft yarn set contains flame resistant yarns and the second weft yarn set contains second weft yarns. The knit fabric is knit such that the first weft yarns are interlinked with one another by a plurality of knit stitches, the second weft yarns are interlinked with one another by a plurality of knit stitches, and the first weft yarns are not interlinked with the second weft yarns.

The invention relates to a process for manufacturing a multilayer knitted textile by heating a multi-layer knitted textile in the presence of one or more dye compounds, wherein the multilayer knitted textile comprises a fabric outer layer and a fabric inner layer, wherein the fabric outer layer is knit from a first yarn containing a combination of modacrylic fibers and cotton fibers, wherein the fabric inner layer is knit from a second yarn made from 50-90% HBA/HNA filaments, wherein the heating shrinks the outer layer from about 5 to 25% in length, width, or both.

The flame retardant yarn of the present invention is made by blending flame retardant viscose fiber and at least one high tenacity flame retarding fiber, the at least one high tenacity flame retarding fiber is flame retardant polyester or flame retardant finishing viscose fiber, wherein the flame retardant viscose fiber is 40˜90% by weight of the flame retardant yarn. The flame retardant yarn takes advantage of the superior flame retardance of the flame retardant viscose fiber, and takes the flame retardant viscose fiber to blend with other good tenacity and spinnability fiber by adjusting amount of raw materials in reasonable balance and avoiding disadvantages of the raw materials to optimize advantages of the flame retardant viscose fiber such as flame retardancy and tenacity so as to provide the flame retardant viscose fiber with high flame retardancy, long lasting flame retardancy effect, strength and elongation performance and good abrasion resistance. Fabric made by the flame retardant yarn not only has good flame retardancy, but also has good elasticity due to high tenacity of the flame retardant yarn.

A machine knittable hybrid yarn for providing conductive traces through a textile is disclosed. The hybrid yarn includes conductive wires coated with an insulating material and twisted together with a nonconductive yarn. The nonconductive yarn is from a strong, inelastic, and nonconductive fiber, such as a meta-aramid or para-aramid that protects the integrity of the conductive wire during knitting. The conductive wire can be copper-clad stainless steel or copper wire is coated with polyurethane, and the nonconductive yarn can have no-drip and no-drip properties to allow ablation of the hybrid yarn to remove the conductive yarn and insulating coating on the wire such that the ablated region becomes externally conductive and suitable for making an electrical contact. The hybrid yarn can be bonded with nylon or similar polymer after twisting.

Embodiments of the invention relate to flame resistant fabrics formed of a combination of filament and long staple yarns that exhibit excellent physical and thermal properties at relatively light weights.

A reinforcing fabric configured for intumescent material expansion includes a woven fabric. The woven fabric has a plurality of composite yarns. Each composite yarn includes a fire resistant component and a crimping component. The crimping component is bonded to the fire resistant component, where the fire resistant component is in a crimped state and the crimping component is in a relaxed state when bonded. The woven fabric is woven with the plurality of the composite yarns with the fire resistant component maintained in the crimped state and the crimping component maintained in the relaxed state in each of the composite yarns. When the woven fabric is imbedded in an intumescent material, the woven fabric is configured to reinforce the intumescent material during heat expansion, and mechanical loads from the expanding intumescent material, in a controlled and predictable manner.
