Embodiments of the invention relate to flame resistant fabrics containing fibers having at least one energy absorbing and/or reflecting additive incorporated into the fibers. Inclusion of such fibers into the fabric increases the arc rating/fabric weight ratio of the fabric while still complying with all requisite thermal protective requirements.

A polymer-sheathed multi-filamentary strand for use in braided covers for wiring harnesses intended for use in challenging embodiments comprises a core of glass filaments wrapped in an aramid yarn, and sheathed in a siloxane-modified polyetherimide polymer. Shielding against electromagnetic interference may also be provided.

Disclosed are exemplary embodiments of woven filtration fabrics that include core-sheath spun yarns in either or both of the warp and weft directions.

Fabrics including a single-ply yarn are described herein along with fabrics that have low picks per inch or low courses per inch. The fabrics may comprise modacrylic fibers, meta-aramid fibers, anti-static fibers, and optionally para-aramid fibers, and the fabrics may comprise: about 10% or 20% to about 60% or 80% modacrylic fibers by weight of the fabric; about 20% or 40% to about 80% meta-aramid fibers by weight of the fabric; about 0.1% to about 2% anti-static fibers by weight of the fabric; and about 0% to about 10% para-aramid fibers by weight of the fabric.

Disclosed are a hybrid fiber cord comprising a nylon filament and an aramid filament, the cord having more uniform physical properties and better strength and fatigue properties and being able to be made more easily than the conventional hybrid fiber cords such that it can be used to make an ultra high performance tire, and a method for manufacturing the same. The hybrid fiber cord comprises a nylon primarily-twisted yarn having a first twist number, and an aramid primarily-twisted yarn having a second twist number. The first twist number is identical with the second twist number. The nylon and aramid primarily-twisted yarns are secondarily-twisted together to have identical structures with each other.

In order to provide a fabric and a fiber product, which have hygroscopicity and durability as well as flame retardancy, a hydrophilizing agent is added to a fabric containing aramid fibers.

Spun yarns, fabrics, and garments with a balance of high thermal and comfort properties are disclosed. Spun yarns made with an intimate blend of fibers including flame resistant fiber, hydrophilic fibers, and anti-static fibers are described. The unique combination of fibers in the spun yarn and fabrics made therefrom provide a balance of high thermal properties, including flame resistance and thermal shrinkage resistance, as well as moisture management properties to provide both protection and comfort to the wearer. In addition, a spun yarn and fabric made therefrom may be dye accepting and/or can be printed thereon. In one embodiment, printable or dye accepting aramid fiber, or producer dyed meta-aramid is utilized in the spun yarn. A fabric made with the spun yarn may have pre-wash softness that makes it comfortable to wear.

The present disclosure relates to a method for manufacturing a hybrid tire cord that utilizes a difference in fineness, and thereby can be more easily manufactured in a form covered with aramid, has uniform physical properties, and improves tire performance.

The present invention relates to a thermally-resistant woven fabric and/or multiple ply fabric sheet for use as single or outer layer of protective garments, of the type comprising an inside fabric layer and an outside fabric layer joined together by an array of connecting lines. The woven fabric and/or multiple ply fabric sheet comprise yarns, wherein said yarn comprises i) meta-aramid ii) from about 5 to 10 weight % of polyamide and iii) at least 2 weight % of antistatic fibers, the weight % being based on the total weight of the yarn.
