A heat insulation material is provided that is produced by drying a fibrous matrix impregnated with a solution of pseudo-peptides of formula (I), wherein: R is a side-chain of a natural or synthetic amino acid , R1 is either a linear or branched (C.sub.1-C.sub.3)alkyl group, or a linear or branched (C.sub.1-C.sub.3)alcoxy group, or an aryl group, or an aryl(C.sub.1-C.sub.3)alkyl group, or an aryloxy group, or a saturated or unsaturated heterocycle, n=1 or 2, and A is an aromatic or heteroaromatic group with at least one cycle.

A heat insulation material is provided that is produced by drying a fibrous matrix impregnated with a solution of pseudo-peptides of formula (I), wherein: R is a side-chain of a natural or synthetic amino acid , R1 is either a linear or branched (C.sub.1-C.sub.3)alkyl group, or a linear or branched (C.sub.1-C.sub.3)alcoxy group, or an aryl group, or an aryl(C.sub.1-C.sub.3)alkyl group, or an aryloxy group, or a saturated or unsaturated heterocycle, n=1 or 2, and A is an aromatic or heteroaromatic group with at least one cycle.

A flame resistant textile is provided. The textile is a sateen weave fabric containing cellulosic fibers, where the sateen weave fabric has a thickness of at least 19.5 mils, a thickness of at least 25 mils after 3 home washes at 120? F., an air permeability of at least 60 cfm, and a weight of less than about 7 oz/yd.sup.2. The sateen weave fabric also contains a treatment, where the treatment contains a tetramethylhydroxy phosphonium salt or its condensate and chemical selected from the group consisting of urea, guanidines, guanyl urea, glycoluril, and polyamines. When the sateen weave fabric to which the treatment has been applied has been heat-cured and oxidized at least a portion of the cellulosic fibers have a pentavalent phosphate compound polymerized therein. The method for producing the flame resistant textile is also provided.
