Definitions
- ABSTRACT A process for imparting flame resistance to textile materials which comprises combining a flame retardant amount of a compound of the formula II II (R0) PCH 4
- : C( ; CH
- R is aryl or alkyl
- Y is -H or lower alkyl
- Z is --I-I or C1-I with a textile selected from the group consisting of a cellulosic material, a proteinaceous material, polyethylene terephthalate and blends thereof.
- One process which involves the use of a single processing bath consists of padding a dispersion of achlorinated hydrocarbon and finely divided antimony oxide on the cellulosic fabric. The fabric is then heated to render the finish wash-proof. Near the combustion temperature, antimony oxide will react with hydrogen chloride, generated by degradation of the chlorinated hydrocarbon, to form antimony oxychloride which suppresses flame.
- the combination of a chlorinated hydrocarbon and finely divided antimony oxide are not acceptable finishes for closely woven fabrics because they deleteriously effect the hand of the finished product.
- Flame resistance has been imparted to cellulosic materials by esterification of the cellulose with diammonium hydrogen orthophosphate. Products so treated are subject to metathesis reactions with cations in aqueous solution during washing, the ammonium cation being displaced by calcium, sodium or magnesium. The flame resistance properties of the diammonium orthophosphate ester of the cellulosic material is then regenerated by reacting the washed product with an ammonium chloride solution.
- R is a univalent hydrocarbon radical independently selected from the group consisting of phenyl and lower alkyl radicals of l to 8 carbon atoms:
- Y is selected from the group consisting of -H and lower alkyl radicals of 1 to 8 carbon atoms;
- Z is selected from the group consisting of H and CH
- This invention also includes methods for imparting flame resistance to textile materials by incorpo' rating into the textile a flame retardant amount of one or more of the compounds of this invention. Furthermore, the flame retardant textile composition forms a third aspect of this invention.
- the compounds of this invention are prepared by conventional methods by the reaction of a tertiary phosphite and an N-hydroxymethyl acrylamide or N- hydroxymethyl methacrylamide and their N-alkylated analogs.
- the latter compounds being produced by the reaction of formaldehyde with acrylamide, methacrylamide or their N-alkylated derivatives.
- the compounds of this invention may be applied to textile materials by conventional finishing techniques such as by thermal or radiation induced pad curing.
- the finished textile product whether subjected to additional finishing treatments or not, exhibits durable, flame resistant properties.
- durable applicants mean the flame retardant is fast to plural laundering or dry cleaning treatments.
- the flame retarding agents of this invention may be applied to various textiles such as cellulosic materials, proteinaceous materials, polyethylene terephthalate, and analogous man-made fibers.
- cellulosic materials applicants intend to embrace cotton, rayon, regenerated cellulose and cellulose derivatives which retain the cellulose backbone and at least one hydroxyl substituent per repeating glucose unit.
- proteinaceous material applicants intend to embrace those textile materials which present the functional groups of protein, such as wool.
- the reaction of amides with formaldehyde is well known to form N-hydroxymethyl derivatives.
- the second step of this sequence may be described as a transesterification reaction of the unsaturated alcohol with the tertiary phosphite ester and a subsequent rearbe in the order of N-hydroxymethylamide/phosphite from about 1/1 to about l/lO.
- a mole of alcohol corresponding to the phosphite used is formed and removed during the reaction.
- excess phosphite is removed by distillation under reduced pressure to yield the product which can be used as such without additional purification.
- the products of this invention have advantages over the flame retardant agents of the prior art in that they may be used on a variety of textile materials ofdifferent chemical compositions and they may be applied by a variety of methods. They may be applied to materials in either the fiber or fabric form to give durable, flame resistant materials with minimum detectable physical changes in the quality of the textile material.
- Cellulosic textile materials may be made flame retardant via a variety of methods.
- Cellulose may be treated with aqueous NaOH solutions to produce an ionic form which will add to the flame retardants of this invention.
- the reaction is by addition of the cellulose alkoxide to the (1,3 unsaturated carbonyl compound of this invention.
- applicants do not wish to be bound by this theory and intend to protect the claimed invention in whatever form or by whatever mechanism it takes. For example,
- Samples of cellulosic material are immersed in a -30 percent by weight NaOH solution for l-2O minutes and squeezed to a wet pick up of 60-80% based upon the weight of cellulosic material using a two roll laboratory padder at 60 pounds per square inch gauge pressure. The samples are then dried at 200275F. from l-5 minutes in a circulating air oven. These samples are then immersed in an aqueous solution of the flame retardant of this invention (-70% by weight) for l-2O minutes and squeezed to 6080% wet weight pick up based upon the weight of textile on a laboratory padder. The materials are then cured in a circulating air oven at 200-275F. for l1O minutes to promote reaction. The samples are then washed in hot water to remove residual unreacted material and dried.
- the products may also be grafted to cellulose via a free radical source generated on the cellulose backbone via electron beam irradiation.
- a free radical source generated on the cellulose backbone via electron beam irradiation.
- Cellulose is known to form stable free radicals under the influence of this type of irradiation.
- the materials to be grafted are immersed in a solution of the phosphorus acrylamide and squeezed in a two roll laboratory padder at 60 pounds per square inch gauge pressure to about 70% wet weight pick up. The materials are then passed under an electron beam two times to give an average dose of 1.66 megarads to induce grafting. The samples are then boiled for one half hour in water to remove any homopolymer of the acrylamide which may have formed and dried.
- the products of this invention may also be applied to ccllulosic materials in combination with other materials to give a cross-linking insoluble polymer.
- ccllulosic materials in combination with other materials to give a cross-linking insoluble polymer.
- the sample of textile material is immersed in an aqueous solution of phosphorus-acrylamide, formaldehyde, trimethylolmelamine, and ZnNO .6H O and squeezed on a two roll padder to 90% wet weight pick up.
- the material is dried at 200-270F for 1-3 minutes and cured at 300370F for l-6 minutes in a circulating air oven.
- the samples are then washed in hot water and dried.
- Electron beam irradiation may also be used to pro mote stable free radicals on polyester fibers made from a dibasic acid and a diol, such as polyethylene terephthalate, and wool in addition to cellulose. Fibers or fabrics of polyester and wool may be made to react with the products of this invention at a dose of 1.66 megarads and greater to produce permanantly grafted materials by the procedure described for cotton above. In addition blends of cotton and polyester may be treated in the same manner to produce uniformly treated fire retardant fiber or fabric blends.
