Disclosed are a sound absorbing fabric with improved thermal insulation, and a method of manufacturing the same, wherein an inorganic aerogel powder and a thermosetting binder resin are impregnated into a non-woven fabric made of a heat-resistant fiber, wherein the inorganic aerogel powder has a surface modified by a surfactant to be uniformly mixed with and dispersed in a binder resin, thereby forming the sufficient number of micro cavities inside the non-woven fabric and increasing dispersibility of the inorganic aerogel powder, and thus heat resistance, sound absorbing and sound insulating properties, and thermal insulation properties can be significantly improved.

Embodiments of the present invention replace at least some of the flame resistant fibers traditionally used in the batting of a thermal liner (e.g., aramids) with thermally stable polyamide fibers (e.g., nylon fibers). The TPP performance of garments incorporating embodiments of thermal liners contemplated herein is comparable toif not improved overgarments formed with traditional thermal liners.

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.

A flame-retardant fiber composite includes an acrylic fiber A containing an acrylic copolymer and an aramid fiber. The acrylic fiber A is substantially free of an antimony compound, and the flame-retardant fiber composite forms a surface-foamed char layer when burned. A flame-retardant work clothing includes the flame-retardant acrylic fiber. A highly flame-retardant fiber composite and highly flame-retardant work clothing include an acrylic fiber, and are capable of exhibiting high flame retardancy while suppressing environmental impacts caused by a flame retardant.
