Definitions
- polyester/cotton blends treated in accordance with the present invention contain between 35% and 80% of polyester, the balance being cotton.
- the nylon/cotton blends contain between 10% and 65% nylon or, when a single treatment step is used, from 3% to 55% nylon, preferably from 35 to 55% nylon.
- Another flame retardant material used in accordance with the present invention specific for the polyester or nylon component of the fabric is a thermally stable cyclic phosphonate ester prepared by reacting alkyl-halogen-free esters with a bicyclic phosphite.
- these cyclic phosphonate esters are represented by one of the formulas:
- R 4 is alkyl (C 1 -C 4 ) phenyl, halophenyl, hydroxyphenyl, hydroxyethyl, phenoxyethyl, dibromophenoxymethyl, tolyl, xylyl, benzyl or phenethyl; and R 5 is monovalent alkyl (C 1 -C 6 ), chlorophenyl, bromophenyl, dibromophenyl, tribromophenyl, hydroxyphenyl, naphthyl, tolyl, xylyl, benzyl, or phenethyl; divalent alkylene (C 1 -C 6 ),vinylene, o-phenylene, m-phenylene, p-phenylene, tetrachlorophenylene (o, m, p), or tetrabromophenylene (o, m, or p); or trivalent phenyl
- Antiblaze 19T as described by the supplier Albright & Wilson Inc., of Richmond, Virginia, U.S.A., is a cyclic phosphonate ester, available as an odorless viscous liquid (viscosity 250 Pa.s) with a flashpoint of 171°C (340°F) (ASTM D-93).
- Hexabromocyclododecane as described by its supplier Great Lakes Chemical Corporation of West Lafayette, Indiana, U.S.A., is a cyclic alkyl bromide, empirical formula C 12 H 18 Br 6 , CAS registry number 25637-99-4, composed of hexabromocyclododecane and related bromocycloalkanes. It is an odorless, water-insoluble, off-white powder having a melting point range of 142-182°C (288-360°F) and is preferably used in the process of this invention as a dispersion in water or an aqueous pad bath system.
- the time in seconds the specimen continues to glow after the specimen has ceased to flame is reported as afterglow time; if the specimen glows for more than 30 seconds, it is removed from the test cabinet, taking care not to fan the glow, and suspended in a draft-free area in the same vertical position as in the test cabinet.
- Char length the distance (in centimeters) from the end of the specimen, which was exposed to the flame, to the end of a lengthwise tear through the center of the charred area to the highest peak in the charred area, is also measured. Five specimens from each sample are usually measured and the results averaged.
- the TPO/ammonia-treated style 9886 fabric was subsequently padded with a 15% Antiblaze 19 (Albright & Wilson) solution, heated in an oven at 193°C for 45 seconds and tested for flame resistance as prepared andafter 25 launderings.
- a 15% Antiblaze 19 Albright & Wilson
- Example 3 A bath containing 50% of a tetrakis- (hydroxymethyl) phosphonium sulfate preparation (Retardol S from Albright & Wilson), 15.7% urea, 9.3% cyclic phosphonateate ester (Antiblaze 19 from Albright & Wilson), 2% disodium phosphate, 2% fabric softener (Aerotex H from American Cyanamid) and 0.1% nonionic surfactant was prepared. This bath was padded onto a dyed and printed nylon/cotton twill (ca. 55% nylon, 264 g/m 2 . Wet pickup was 61.5%. The fabric was dried and cured for 90 seconds in an oven at 182°C. The treated fabric was oxidized in a solution contaiing hydrogen peroxide and sodium hydroxide, rinsed well and dried.
- a tetrakis- (hydroxymethyl) phosphonium sulfate preparation (Retardol S from Albright & Wilson), 15.7% urea, 9.3%
