Definitions

• a fiame-resistant textile article comprising filaments, staple fibers or yarns from natural and/or synthetic material and a homogeneous mixture consisting of a halogen phosphoric acid esters, a phosphorus-containing plasticizing agent, a polyalkyl halide, antimony oxide, and a polyurethane.
• the present invention relates to flame-resistant textile material and to a method for flameproofing textile fabrics, e.g. floor coverings, upholstery cloth, wall coverings, curtaining material, and industrial textile material of synthetic, regenerated and natural fibers, as well as mixtures thereof, which contain mixtures of phosphorus-containing compounds, polyalkyl halides, antimony compounds, and polyurethanes as fiameproofing agents.
• textile fabrics e.g. floor coverings, upholstery cloth, wall coverings, curtaining material, and industrial textile material of synthetic, regenerated and natural fibers, as well as mixtures thereof, which contain mixtures of phosphorus-containing compounds, polyalkyl halides, antimony compounds, and polyurethanes as fiameproofing agents.
• fiameproofing agents must not increase the aflinity of the textile to dirt or produce a superficially visible covering, and the finish they produce must be resistant to washing, cleaning, in particular using vacuum cleaners, shampooing, abrasion, vacuum cleaning and aging.
• the homogeneous mixture can also be applied as an intermediate coating by the application of a lining fabric, subsequently to the doctor blade finishing procedure and can thus simultaneously serve as a lining material or adhesive.
• Another advantage of the used as flameproofing agents resides in improved rebound properties of the textile fabrics treated therewith and, in connection therewith, a lower tendency of forming creases and wrinkles during processing and when worn.
• the flameproofing agents to be used according to the invention are applied in quantities between 5 and 150% by weight, preferably 40 to based on the weight of the textile fabric to be treated.
• the quantities to be applied are substantially lower than the quantities conventionally used for obtaining normal coatings, e.g. for awning cloth and waterproof cloth.
• the textiles being treated according to the invention are permeable to steam and air.
• the individual components are preferably employed in quantities (phosphoric acid compoundzpolyalkyl halidezantimony oxidezpolyurethane) of 1:0.2:0.05:0.1 to 1:1:0.5:1.
• halogen-phosphoric acid esters tris-halogenalkylphosphate are used.
• Suitable phosphorus-containing plasticizing agents are triaryl phosphate or trialkyl phosphate.
• Stabilizing agents for polyvinylchloride such as triphenyl phosphite or diphenyl thiourea may be added.
• Examples of phosphorus-containing compounds which are effective both as flame-inhibiting agents and as plasticizers are phosphoric acid esters, such as tritoluyl phosphate, tricresyl phosphate, triphenyl phosphate, diphenylcresyl phosphate, trioctyl phosphate, diphenyloctyl phosphate, tr i s chloroethyl)-phosphate, tris-(dichloroethyl)- phosphate, tris-(dichloropropyl) phosphate, tris (dichlorobutyl)-phosphate, tris- (brornoethy1)-phosphate, tris- (dibromoethyl)-phosphate, tris-(dibromopropyl) phosphate, bis-(dichloropropyl)-propylphosphate, and mixtures thereof.
• phosphoric acid esters such as tritoluyl phosphate
• polyalkyl halides are polyvinyl chloride and polyvinyl bromide compounds of the molecular weight in the range of 30,000 to 150,000.
• the products must be capable of being processed in the form of pastes and must contain at least 25 to 30% by weight of a plasticizer.
• Copolymers thereof e.g. with vinylacetate, vinylidenechloride, maleic and fumaric acid esters, styrene, acrylic esters and acrylonitrile can also be used.
• Suitable polyesters and polyethers are polyesters of adipic acid/hexanediol-1,6 having a molecular weight of about 2,000 or of terephthalic acid/ethyleneglycol or/ and polypropylene oxide ether.
• the polyurethanes used as prepolymers being prepared by reaction of a polyester and/or polyether with a polyisocyanate in a molar ratio of 1:1. Reaction products from ethanolamines and isocyanates, e.g. from N-methyldiethanolamine and phenylisocyanate, are used as catalysts.
• the antimony compound is used as antimony trioxide in pulverized or suspended form.
• the textiles to be treated are made of fibers and filaments of natural and synthetic origin, e.g. of polyamides, polyacrylonitriles, polyesters, polyalkylenes, polycarbonates, polyurethanes, halogenated polyolefines, regenerated cellulose, cotton and wool or mixtures thereof.
• the moulded fabrics e.g. coated fabrics of fibers and homogeneous mixtures according to the invention when 70 filaments as described above or textiles containing an intel-mediate coating of the herein described flameproofing material are distinguished over non-treated material by a substantially reduced flammability.
• the herein described method and the mixtures to be used as flameproofing agents according to the invention are especially suitable in the treatment of textile fabrics of polyacrylonitrile fibers.
• a specific advantage of the herein described process consists in that the action of flames does not effect a dropping melt.
• the technological data of the textiles treated according to the invention are affected either not at all or to an immaterial degree only.
• the resiliency of the materials treated according to the invention is increased.
• a further advantage is the resistance to washing and solvents of the textile fabrics treated according to the invention.
• Textile fabrics can be rendered flame-resistant by coating the textile material with the mixtures according to the invention by means of doctor blades (a doctor arrangement) and subsequently drying the textile material thus treated in a drying chamber at 70 to 160 C.
• the blades are to be adjusted in such a manner that the coatings of the dry coating material, referred to the weight of the textiles, range between 5 to 150% by weight, preferably between 40 and 70% by weight.
• the coating is to be accomplished so that the textile material treated substantially retains its permeability to air and steam.
