Provided is a flame-resistant airbag having a low rate of combustion. The flame-resistant airbag is obtained by forming, on a cloth substrate, a cured film of a composition containing: (A) 100 parts by mass of a liquid organopolysiloxane containing an alkenyl group bonded to a silicon atom; (B) 5 to 100 parts by mass of a three-dimensional network-structured organopolysiloxane resin in which 0.05 to 0.15 mol/100 g alkenyl groups are bonded only to D units, the ratio of M units to T and/or Q units is 0.65 to 1.40, and hydroxyl group content is 0.040 mol/100 g or less; (C) 0.1 to 50 parts by mass micropulverized silica having a specific surface area of at least 50 m.sup.2/g; (D) an organohydrogen polysiloxane comprising a hydrogen atom bonded to a silicon atom, in an amount such that the number of hydrogen atoms bonded to silicon atoms in component (D) is 1 to 10 per total 1 alkenyl group bonded to a silicon atom in components (A) and (B); (E) an effective amount of a platinum group metal catalyst; and (F) 0.1 to 10 parts by mass of an organic silicon compound.

Flame resistant fabrics having antimicrobial properties that combat odor and/or resist hazardous microorganisms. The fabrics are particularly suitable for use in clothing and more particularly in protective garments designed to be worn by individuals, such as military personnel and emergency rescue personnel, at risk of exposure to fire and extreme temperatures as well as hazardous substances. The fabrics may be formed in a variety of ways, including, but not limited to, incorporating antimicrobial fibers into the flame resistant fabric yarn or by treating the pre-formed flame resistant yarn or fabric with antimicrobial agents in a dyeing or finishing process.

A description is given of continuous fibers based on cellulose and/or cellulose derivatives, more particularly for producing flame-retardant textiles or carbon fibers. The cellulose and/or the cellulose derivatives are in a dehydrated form in the continuous fibers. The oxygen content is 29 to 39 wt %, the limiting oxygen index LOI is 25 to 40 (according to DIN EN ISO 6941; 2004-05) and the density is 1.3 to 1.45 g/cm.sup.3 (according to DIN 65569-1; 1992-10). The continuous fibers may be produced advantageously by impregnating the starting fibers with a solution, more particularly an aqueous solution, of a specific salt which under thermal conditions releases a dehydrating acid which brings about the dehydration of cellulose and/or of cellulose derivatives in a subsequent thermal stage. The continuous fibers of the invention can be used in particular to produce advantageous carbon fibers.

Use of an electrically charged nonwoven fabric that is made of a fiber predominantly composed of an amorphous polymer provides a novel filtration material having improved performance compared to that of conventional filtration materials, and having excellent heat resistance and excellent flame retardancy as well as an electrically charged nonwoven fabric for use in the filtration material.
