       le     2,2-bis(bromométhyl)-1,3-prepyl%ne-bis(2-bromo-3-naphtyl-          propyl-2-chloropropyl-phosphate);    le 2,2-bis(bromométhyl)       1,3-propyl%ne-bis(2-bromo-6-chlorohexyl-2-bromo-éthyl-          phosphate);    le     2,2-bis(ehlorométhyl)-1,3-propyléne-bis-          rbis(2-chloro-1-méthylpropyl)-phosphate7;    le 2,2-bis(bromo       méthyl)-1,3-propyléne-bis(2-bromo-1-butylhexyl-?_-chloro-1-          butylhexyl-phosphate);    le     2,2-bis(chlorométhyl)-1,3-          propyléne-bis@is(2-chloro-3-phénoxypropyl)-phosphate7;

       le     2,2-bis(bromométhyl)-1,3-propylène-bis(2-bromo-5-          butényloxypentyl-2-chloropropyl-phosphate);    le 2,2-bis       (bromométhyl)-1,3-propyl>ne-bis(2-bromo-4-propynyloxybutyl-          2-bromobutyl-phosphate);    le     2,2-bis(bromométhyl)-1,3-          propylène-bis(2-bromo-3-acrylyloxypropyl-2-        chloro-3-          acrylyloxypropyl-phosphate);    le 2,2-bis(chlorométhyl)-1,3       propylène-bis(2-chloro-4-octylcarboxybutyl-2-chlorohexyl-          phosphate);

  Les     diphosphates    utilisés pour exécuter l'invention  peuvent contenir des isomères ainsi que certains produits  provenant de réactions secondaires et qui se forment dans  les stades intermédiaires de la préparation.      Selon la proportion du     diphosphate,    on obtient  également un effet de plastification ou de ramollissement.  Ainsi, â la concentration par exemple de 10 à 50     %    en       diphosphate    halogéné par rapport     è.    l'ensemble des fibres  et du phosphate, le     polymère    est en général non seulement       ignifugé    mais également plastifié.  



  Les     diphosphates    halogénés peuvent     9tre    utilisés  en une quantité égale à celle des fibres mais dans la  <B>plupart</B> des cas on obtient des résultats favorables en ce  qui concerne l'ignifugation     é    des concentrations nettement  plus basses (pouvant descendre     jusqu'l    1     %).     



  Le traitement aux     diphosphates    halogénés procure  souvent aussi aux fibres une amélioration de certaines       caractéristiques    telles que par exemple la stabilité des  dimensions.  



  Le procédé selon l'invention est plus particuliè  rement intéressant dans son application â l'ignifugation  des fibres textiles cellulosiques, de coton, de lin, de  chanvre, de cellulose régénérée, d'esters ou d'éthers  cellulosiques. On obtient dans ce cas non seulement une  ignifugation mais aussi une amélioration de la main ou  du toucher de l'étoffe.  



  Le procédé s'applique toutefois aussi<B>à</B> l'ignifu  gation des fibres en     polymères    synthétiques, linéaires ou  réticulés, obtenus aussi bien par     polymérisation    par  addition que par condensation.      Parmi les polymères on peut citer les polymères  et copolymères de composés vinyliques et     vinylidéniques,     c'est-à-dire ceux qui comportent le reste
EMI0005.0002  
   de  composés portant le groupe éthylénique
EMI0005.0003  
   de  composés polymérisables ayant plusieurs doubles liaisons,  ainsi que les polyuréthanes, les polyamides, les polyesters,  etc.  



  L'essai     dtinflammabilité    pour déterminer les  propriétés de combustion des fibres traitées est<B>essentiel-</B>  lement l'essai de combustion standard, selon la méthode       ASTM-D1692-D59T    ou une variante de cette méthode. D'une       manière        générale,    cet essai consiste â faire brûler les  fibres textiles dans une tour à tirage     réglé    et â déterminer  la manière dont se fait la combustion.

   L'échantillon est  supporté sur une toile métallique de 6 mm, les dimensions  de 15 et 5 de l'échantillon étant horizontales et on trace  deux traits     é.    10 cm     l'ûn    de     ltautre    sur l'échantillon,  lequel est allumé avec un brûleur â une     extrémité,    Le temps  d'allumage est de 1 minute ou bien jusqu'à ce que la partie  antérieure de la flamme atteigne le premier trait rencontré.  Le brûleur est retiré après l'inflammation.  



  On classe en deux catégories les échantillons  des fibres textiles qui ne brûlent pas:  1.     Echantillons    pour lesquels il n'y a pas de combustion.  



  2.     Echantillons    pour lesquels la combustion     s'arréte    d'elle  m8me.      Les     fibres    sont considérées comme ne donnant pas  lieu à une combustion lorsqu'on n'observe pas de combustion,  c'est-à-dire de flamme ou d'incandescence qui progresse,  après qu'on a retiré le brûleur. Un échantillon dont la  combustion s'arrête d'elle-même est un échantillon qui  continue à brûler après qu'on a retiré le brûleur, mais  dont la flamme disparaît     avant    d'avoir atteint le second  trait de     marque.     



  Les exemples suivants illustrent l'invention.  <U>Exemple 1</U>  On imprègne des étoffes en coton avec diverses  teneurs de     2,2-bis(halométhyl)-1,3-propyléne-bis(halo-          phosphate),    selon le processus suivant:  On dissout le     diphosphate    dans un solvant volatil,  par exemple la     méthyl-étnyl-cétone    et on trempe dans cette  solution l'étoffe en coton. Le solvant est ensuite évaporé.  Pour obtenir une absorption plus rapide, on peut effectuer  le trempage sous vide.  



  La teneur de la solution nécessaire pour obtenir  un taux voulu de     diphosphate    dans des fibres textiles en  coton, est d'environ 2 fois le taux dans la matière imprégnée.  



  On     sècrie    des bandes de 15 x 5 cm d'étoffe dans une  étuve à<B>13000</B> pendant 10 minutes et on les pèse puis on les  place dans des     flacons    de verre contenant environ 50 cm 3  d'une solution dans la     méthyl-éthyl-cétone    contenant divers      pourcentages des composés chimiques à essayer A, B, C, D,  définis ci-dessus. Les flacons sont inclinés si cela est  nécessaire, pour recouvrir entièrement les bandes de la  solution d'imprégnation. Au bout d'une minute on retire  les bandes en étoffe, on les secoue     pour    en éliminer       lt-excés    de solution et on les presse entre deux feuilles  de papier, sous un poids d'un kilo.

   On pèse ensuite les  bandes et on les sèche     é,    l'air pendant 2 minutes puis on  étuve â 130 C pendant 10 minutes.     Ltessai    montre que pour  obtenir une étoffe imprégnée     dtenviron    20     ,%    en poids du  corps chimique, il est nécessaire     dtutiliser    une solution  â environ 25     ,%    en poids du corps chimique dans le solvant.  



  On     soumet    les bandes à l'essai de combustion  selon la méthode standard. Les résultats sont les     suivants:     Caractéristiques de combustion du coton imprégné

  The present invention relates to a process for igniting textile fibers, raw or already processed, by treating them by means of a halogenated diphosphate.



  According to this invention, the textile fibers are treated with a halogenated organic diphosphate of the formula
EMI0001.0006
    uo # X denotes bromine or chlorine, R denotes hydrogen or a hydrocarbon, halohydrocarbon, hydrocarbon-oxy, hydrocarbon-oxyalkyl or hydrocarbon-C (0) 0-alkyl residue and R 'denotes the hydrogene or an alkyl residue or lower haloalkyl,

   R ′ being lthydrog% ne when R is a hydrocarbon-oxyalkyl or hydrocarbon-C (0) 0-alkyl residue.



  These halogenated organic diphosphates can% be prepared by reacting the reaction product of pentaerythritol and a trivalent phosphorus trihalide, that is to say phosphorus tri chloride or tribromide, (the main product thus formed being the test chlorophosphorous acid pentaerythritol) with chlorine or bromine,

   then reaction of the product obtained with an epoxide of formula
EMI0002.0019
    in which R and Rt have the definitions given above. Examples of such diphosphates are: 2,2-bis (chloromethyl) -1,3-propylene-bisiis- (2-chloroethyl) -phosphate7; 2,2-bis (chloromethyl) -1,3-propyl% ne-bis 2-bromopropyl-2-chloropropyl-phosphate7; 2,2-bis (bromomethyl) -1,3-propyl% ne-bisz2-, 3-dichloropropyl-2-bromo-3-chloropropyl-phosphate7;

      2,2-bis (bromomethyl) 1,3-propylene-bis (3-phenoxy-2-chloroproPyl-3-phenoxy-2-bromopropyl-phosphate); 2,2-bis (bromomethyl) -1,3-propyl% ne-bi sCbi s (2-bromo-3-butenyl) -phosphate7; 2,2-bis (bromomethyl) -1,3-propyl% ne-bis (2-bromo-11-dodecenyl-2-ohloro-11-dodecenyl-phosphate); 2,2-bis (chloromethyl) - 1,3-propylene-bis (2-chloro-4-pentynyl-2-chloroethyl-phosphate);

       2,2-bis (bromomethyl) -1,3-prepyl% ne-bis (2-bromo-3-naphthyl-propyl-2-chloropropyl-phosphate); 2,2-bis (bromomethyl) 1,3-propyl% ne-bis (2-bromo-6-chlorohexyl-2-bromo-ethyl-phosphate); 2,2-bis (ehloromethyl) -1,3-propylene-bis-rbis (2-chloro-1-methylpropyl) -phosphate7; 2,2-bis (bromo methyl) -1,3-propylene-bis (2-bromo-1-butylhexyl -? _-chloro-1-butylhexyl-phosphate); 2,2-bis (chloromethyl) -1,3-propylene-bis® is (2-chloro-3-phenoxypropyl) -phosphate7;

       2,2-bis (bromomethyl) -1,3-propylene-bis (2-bromo-5-butenyloxypentyl-2-chloropropyl-phosphate); 2,2-bis (bromomethyl) -1,3-propyl> ne-bis (2-bromo-4-propynyloxybutyl-2-bromobutyl-phosphate); 2,2-bis (bromomethyl) -1,3-propylene-bis (2-bromo-3-acrylyloxypropyl-2-chloro-3-acrylyloxypropyl-phosphate); 2,2-bis (chloromethyl) -1.3 propylene-bis (2-chloro-4-octylcarboxybutyl-2-chlorohexyl-phosphate);

      and 2,2-bis (bromomethyl) -1,3-propylene-bis (2-bromo-4-methacrylyloxybutyl-2-bromo-3-chloropropyl-phosphate).



  The diphosphates used to carry out the invention may contain isomers as well as certain products resulting from side reactions and which are formed in the intermediate stages of the preparation. Depending on the proportion of the diphosphate, a plasticizing or softening effect is also obtained. Thus, at the concentration for example of 10 to 50% of halogenated diphosphate with respect to è. all the fibers and the phosphate, the polymer is generally not only flame retardant but also plasticized.



  The halogenated diphosphates can be used in an amount equal to that of the fibers, but in <B> most </B> cases favorable results are obtained with regard to flame retardancy at significantly lower concentrations (which may drop to as low as l 1%).



  The treatment with halogenated diphosphates often also gives the fibers an improvement in certain characteristics such as, for example, dimensional stability.



  The process according to the invention is more particularly advantageous in its application to the fireproofing of cellulose, cotton, flax, hemp, regenerated cellulose, esters or cellulose ethers fibers. In this case, not only flame retardancy is obtained but also an improvement in the hand or the feel of the fabric.



  However, the process also applies <B> to </B> the flame retardation of fibers made of synthetic polymers, linear or crosslinked, obtained both by addition polymerization and by condensation. Among the polymers, mention may be made of polymers and copolymers of vinyl and vinylidene compounds, that is to say those which contain the remainder
EMI0005.0002
   compounds bearing the ethylene group
EMI0005.0003
   polymerizable compounds having several double bonds, as well as polyurethanes, polyamides, polyesters, etc.



  The flammability test to determine the combustion properties of treated fibers is <B> primarily- </B> the standard combustion test, according to ASTM-D1692-D59T or a variation thereof. In general, this test consists in burning the textile fibers in a controlled draft tower and determining the manner in which the combustion takes place.

   The sample is supported on a 6 mm wire mesh, the dimensions of 15 and 5 of the sample being horizontal and two lines are drawn. 10 cm from the other on the sample, which is ignited with a burner at one end. The ignition time is 1 minute or until the front part of the flame reaches the first mark encountered. The burner is removed after ignition.



  Samples of textile fibers which do not burn are classified into two categories: 1. Samples for which there is no combustion.



  2. Samples for which combustion stops by itself. The fibers are considered not to give rise to combustion when combustion, i.e. flame or progressing glow, is not observed after the burner has been removed. A sample that stops burning on its own is a sample that continues to burn after the burner has been removed, but whose flame disappears before reaching the second mark.



  The following examples illustrate the invention. <U> Example 1 </U> Cotton fabrics are impregnated with various contents of 2,2-bis (halomethyl) -1,3-propylene-bis (halophosphate), according to the following procedure: Dissolve the diphosphate in a volatile solvent, for example methyl-ethyl-ketone, and the cotton cloth is soaked in this solution. The solvent is then evaporated off. To obtain a faster absorption, the soaking can be carried out under vacuum.



  The content of the solution required to obtain a desired level of diphosphate in cotton textile fibers is about 2 times the level in the impregnated material.



  15 x 5 cm strips of fabric are dried in a <B> 13000 </B> oven for 10 minutes and weighed and then placed in glass vials containing about 50 cm 3 of a solution in the methyl-ethyl-ketone containing various percentages of the chemical compounds to be tested A, B, C, D, defined above. The vials are tilted if necessary, to completely cover the bands with the impregnation solution. After one minute the strips of cloth are removed, shaken to remove excess solution, and pressed between two sheets of paper, under a weight of one kilogram.

   The strips were then weighed and dried in air for 2 minutes and then incubated at 130 ° C. for 10 minutes. The test shows that in order to obtain a fabric impregnated with about 20% by weight of the chemical body, it is necessary to use a solution of about 25% by weight of the chemical in the solvent.



  The strips are subjected to the combustion test according to the standard method. The results are as follows: Burning characteristics of impregnated cotton
