A ring composite spinning method based on film filamentization is provided, which belongs to a textile technical field. According to the method, a film cutting drafting device is arranged above each drafting system on a ring spinning machine for cutting film material into ribbon-shaped multi-filaments to achieve the film filamentization, which changes a conventional formation of filament through linear spraying by spinneret orifices; then the multi-filaments formed pass through first and second filament drafting zones in sequence for drawing, so as to enhance and attenuate the multi-filaments. After in drawing, the multi-filaments are twisted with conventional staple fibers to form a composite yarn with high quality and functions, achieving one-step production of composite yarns of nano-micro fibers without online combination of nanofibers spinning and ring staple spinning, thereby breaking restriction of low bulk and low-speed production of nano-spun fibers and integrating film industry with textile industry.

A hybrid cord for a tire, a method of manufacturing the same, and a high-performance environment-friendly radial tire including the same are disclosed herein. The hybrid cord includes a high-modulus fiber ply and a low-modulus fiber ply. The hybrid cord has a stress-strain curve including an initial modulus section, an intermediate modulus section and a final modulus section. The initial modulus of the initial modulus section is higher than the intermediate modulus of the intermediate modulus section, and the final modulus of the final modulus section is higher than the intermediate modulus.

Lightweight fabrics with a balance of high thermal properties, especially arc resistance and flash fire resistance, on the one hand, and durability and comfort properties, on the other hand, are disclosed. Articles, such as garments and linen, made from the lightweight fabrics are also disclosed. Spun yarns made with an intimate blend of fibers including flame resistant fiber, fire-resistant hydrophilic fibers, and a low level of anti-static fibers are described. The lightweight fabrics are particularly useful in garments for utility workers, industrial workers, military personnel, and firefighters.

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 hybrid fiber which includes: a metal wire having a roughened surface; and a fiber is provided. In the hybrid fiber, the metal wire and the fiber are combined.

Lightweight, dyeable fabrics with a balance of high thermal properties, especially arc resistance, on the one hand, and durability and comfort properties, on the other hand, are disclosed. Articles, such as garments and linen, made from the lightweight dyeable fabrics are also disclosed. The fabrics are particularly useful in garments for utility workers, industrial workers, military personnel, and firefighters, especially for use in environments requiring high visibility.

Multifunctional protective footwear for canines is provided with a vertical zone, a transition zone and a horizontal zone. At least the horizontal zone, adjacent the pad of a canine's foot contains a combination of at least two fabric materials, a) silicone rubber threads or yarns combined with b) meta- or para-aramids, a) and b) combined within proportions of 5-95% and 95-5% by total fabric weight of the footwear weight respectively. Up to 50% of the total footwear weight may be replaced by other fiber materials, with the combinations of a) and b) constituting the remaining total weight of the footwear as 5-45% and 45-5% by total fabric weight of the footwear weight respectively.
