  <U>Procédé de finissage de matières textiles et produit textile ainsi</U>  <U>obtenu.</U>  



  On     connait    un procédé de finissage de textiles avec des résines     amino-          plastes    comprenant la fixation additionnelle sur le textile d'un polymère  contenant des groupes carboxyliques, cette fixation étant obtenue par  la     réticulation    "in situ" d'une substance organique contenant des grou  pes carboxyliques et le cas échéant, d'autres groupes servant de posi-           tions    réactives pour la     réticulation    (voir brevet belge No. 574 437).

    En général, les substances organiques contenant les groupes     carbo-          xyles    mises en oeuvre dans ce procédé consistent en polymères ou       copolymères        â.    base d' acide acrylique, d' acide méthacrylique, d' a  cide maléique et composés similaires.  



  L' objet de la présente invention est un procédé de finissage de ma  tières textiles avec des résines aminoplastes, en vue de les rendre  moins sujettes     à.    une dégradation chimique quand on les lave dans des  solutions d' agents de blanchiment contenant du chlore. Ce     procédé     est caractérisé parle fait     qu'    on fixe en outre sur le textile un acide  de formule générale.  
EMI0002.0010  
   re  présente l'hydrogène, le radical méthyle ou éthyle et oh R2 est un  résidu aliphatique ou aromatique, le textile étant     finalement    traité  avec un alcali.  



  L' invention a également pour objet le produit textile obtenu par ledit  procédé.      Le procédé selon l'invention présente, par rapport à celui du brevet  belge No. 574. 437, les avantages suivants ;  Dans le procédé selon l'invention le composé additionnel à groupes  carboxyle qui est appliqué au tissu, est un monomère qui peut pénétrer  avec le     précondensat    résineux dans la fine structure de la fibre et  être fixé dans la fibre avec la résine; cela permet de conserver la  douceur et la souplesse du tissu même en cas d'utilisation de gran  des quantités du composé carboxylique.  



  Dans le procédé du brevet belge No. 574 437 par contre, le composé  à groupes carboxyle est un polymère qui, de ce fait, ne peut pas  pénétrer profondément dans la fine structure de la fibre. Il est donc  insolubilisé en grande partie sur la surface de la fibre au cours de  la mise en oeuvre du procédé.     Etant    déposé et fixé sur la fibre, on  ne peut en appliquer qu'une quantité limitée si l' on veut éviter un  raidissement appréciable du tissu.  



  Avec le procédé selon l'invention en outre, la latitude est beaucoup  plus grande en ce qui concerne la quantité pouvant être appliquée de      composé à groupes carboxyle, qui fonctionne comme agent protecteur  de la résine; cela constitue un avantage particulièrement lorsque la       résine    aminoplaste est susceptible d' absorber des quantités peu im  portantes de chlore et     qu'    elle nécessite par conséquent une quantité  peu importante     d'    agent protecteur pour fournir un apprêt qui résiste  complètement au chlore.  



  Le mécanisme exact, par lequel l' acide est fixé sur les fibres .n' est  pas clair; il peut consister en une réaction avec les groupes hydro  xyles de la cellulose ou en une interaction avec la résine azotée au  cours de la fixation sur les fibres.  



  Il est commode d' appliquer l' acide au textile avec la résine     précon-          densée    et de le fixer en même temps que celle-ci, mais on peut évi  demment appliquer l' acide avant ou après la substance engendrant  la résine.  



  Des acides appropriés sont l' acide     N-méthylol,-succinamique,    l' aci  de     N-méthylol-phtalamique,    l' acide     N-méthylol-hydroxysuccinamique     et l' acide     N-méthylol-maléamique.         Ces acides sont les     dérivés        N-méthylol    de diacides     monoamidés     et sont préparés facilement â partir de ceux-ci par réaction avec  la     formaldéhyde.        Quoiqu'    il soit préférable de préparer *le compo  sé     N-méthylol    avant l' adjonction à la résine     précondensée,

      il est  possible d' ajouter le diacide     monoamidé    à la résine     précondensée     et de produire la réaction formant le dérivé     N-méthylol    soit dans  ladite solution soit sur le textile après imprégnation avec la solu  tion.  



       Exemple   <U>1</U>  Un tissu uni de coton blanchi et mercerisé écru 80 x 80     30'9/30's     est imprégné d'une solution contenant 9. 0     %    d'un     précondensat     d'     éthyléneurée    cyclique avec la     formaldéhyde,    , 0, 5     %    de cire de  paraffine     émulsifiée,    0, 25     %    du produit marque     "Ceranine    FE"  (un agent adoucissant,

   1     %    de chlorure d'ammonium et 2 1/2  d'une solution â 20     %        p/v    d'acide     N-méthylol-        succinamique.    Après  imprégnation, le tissu est calandré de façon à retenir 80     %    de son  poids de liquide puis il est     séché    â l' air chaud et porté pendant 5  minutes à une température de 130 C. On le lave ensuite pendant 5  minutes â     500C    dans une solution contenant 0, 1      j     de carbonate de      sodium, puis on le rince â l' eau et le sèche.  



  On obtient ainsi un tissu présentant une perte de résistance â la  traction de 2, 5     %    seulement après une sévère épreuve de lavage,  suivie de trois traitements successifs de     chloruration    et de repas  sage â chaud, tandis qu'un tissu fini de façon similaire mais sans  la protection apportée par l' acide     N-méthylol-succinamique    subit  une perte de résistance â la traction de 45     %.     



  <U>Exemple 2</U>  Un tissu uni de coton blanchi et mercerisé écru 80 x 80, 30' s30' s  est imprégné d'une solution contenant     30%    d'un     précondensat    obte  nu en faisant réagir de façon connue<B>100</B> g d'urée et 500 ml d'une  solution aqueuse de     formaldéhyde    à 40      j0    puis en diluant â 1000 ml.

    La solution d'imprégnation contient en outre 0, 5     %    de cire de  paraffine     émulsifiée,    0, 25     %    de     "Eeranine    FE"     @1        %    de phosphate  diacide d'ammonium et 10      %    d' une solution à 20      j0        p%v    d' acide       N-méthylol-phtalamique.    Après imprégnation, le tissu est     calan-          dré    de façon à retenir 80     %    de son poids de liquide,

   puis il est sé  ché à l' air chaud et porté pendant 5 minutes â     500C    dans une solu  tion contenant 0, 1     %    de carbonate de sodium, puis on le rince â  l' eau et le sèche.      On obtient ainsi un tissu présentant une perte de résistance à la  traction de 4, 8      %    seulement après une sévère épreuve de lavage  suivie de trois traitements successifs de     chloruration    et de repas  sage à chaud, tandis que un tissu fini de façon similaire, mais  sans la protection apportée par l'acide     N-méthylol-phtalamique,     subit une perte de résistance à la traction supérieure à 34      jo.  



  <U> Process for finishing textile materials and textile product thus obtained </U> <U>. </U>



  There is known a process for finishing textiles with amino plast resins comprising the additional attachment to the textile of a polymer containing carboxylic groups, this attachment being obtained by the "in situ" crosslinking of an organic substance containing groups. carboxylic and, where appropriate, other groups serving as reactive positions for the crosslinking (see Belgian Patent No. 574,437).

    In general, the organic substances containing the carbonyl groups used in this process consist of α polymers or copolymers. based on acrylic acid, methacrylic acid, maleic acid and similar compounds.



  The object of the present invention is a process for finishing textile materials with aminoplast resins, with a view to making them less prone to. chemical degradation when washed in bleach solutions containing chlorine. This process is characterized by the fact that an acid of general formula is additionally fixed to the textile.
EMI0002.0010
   re presents hydrogen, methyl or ethyl and where R2 is an aliphatic or aromatic residue, the textile being finally treated with an alkali.



  A subject of the invention is also the textile product obtained by said process. The process according to the invention has the following advantages compared to that of Belgian patent No. 574. 437; In the process according to the invention the additional compound containing carboxyl groups which is applied to the fabric, is a monomer which can penetrate with the resinous precondensate into the fine structure of the fiber and be fixed in the fiber with the resin; this makes it possible to maintain the softness and suppleness of the fabric even when large amounts of the carboxylic compound are used.



  In the process of Belgian Patent No. 574,437, on the other hand, the compound with carboxyl groups is a polymer which, therefore, cannot penetrate deeply into the fine structure of the fiber. It is therefore largely insolubilized on the surface of the fiber during the implementation of the process. As it is deposited and fixed on the fiber, only a limited amount can be applied if one wishes to avoid appreciable stiffening of the fabric.



  With the process according to the invention further, the latitude is much greater as to the applicable amount of the compound having carboxyl groups, which functions as a protective agent for the resin; this is of particular advantage when the aminoplast resin is capable of absorbing small amounts of chlorine and therefore requires a small amount of protective agent to provide a finish which is completely chlorine resistant.



  The exact mechanism by which the acid is attached to the fibers is not clear; it may consist of a reaction with the hydroxyl groups of the cellulose or of an interaction with the nitrogenous resin during attachment to the fibers.



  It is convenient to apply the acid to the fabric with the precondensed resin and fix it at the same time as it, but of course the acid can be applied before or after the resin generating substance.



  Suitable acids are N-methylol, -succinamic acid, N-methylol-phthalamic acid, N-methylol-hydroxysuccinamic acid and N-methylol-maleamic acid. These acids are the N-methylol derivatives of monoamide diacids and are readily prepared from them by reaction with formaldehyde. Although it is preferable to prepare * the N-methylol compound before addition to the precondensed resin,

      it is possible to add the monoamide diacid to the precondensed resin and to produce the reaction forming the N-methylol derivative either in said solution or on the textile after impregnation with the solution.



       Example <U> 1 </U> A plain fabric of bleached and unbleached mercerized cotton 80 x 80 30'9 / 30's is impregnated with a solution containing 9. 0% of a cyclic ethyleneurea precondensate with formaldehyde,, 0, 5% emulsified paraffin wax, 0, 25% of the product brand "Ceranine FE" (a softening agent,

   1% ammonium chloride and 2 1/2 of a 20% w / v solution of N-methylol-succinamic acid. After impregnation, the fabric is calendered so as to retain 80% of its weight of liquid, then it is dried in hot air and brought for 5 minutes to a temperature of 130 C. It is then washed for 5 minutes at 500 ° C. in a washing machine. solution containing 0.1 d of sodium carbonate, then rinsed with water and dried.



  There is thus obtained a fabric exhibiting a loss of tensile strength of only 2.5% after a severe wash test, followed by three successive treatments of chlorination and hot meal, while a similarly finished fabric but without the protection afforded by N-methylol-succinamic acid suffered a loss in tensile strength of 45%.



  <U> Example 2 </U> A plain fabric of bleached and unbleached mercerized cotton 80 x 80, 30 's30' s is impregnated with a solution containing 30% of a precondensate obtained naked by reacting in a known manner <B > 100 </B> g of urea and 500 ml of an aqueous solution of formaldehyde 40 days, then diluting to 1000 ml.

    The impregnation solution further contains 0.5% emulsified paraffin wax, 0.25% "Eeranine FE" @ 1% diacid ammonium phosphate and 10% of a 20% solution. N-methylol-phthalamic acid. After impregnation, the fabric is calendered so as to retain 80% of its weight of liquid,

   then it is dried in hot air and heated for 5 minutes at 500 ° C. in a solution containing 0.1% sodium carbonate, then it is rinsed with water and dried. There is thus obtained a fabric exhibiting a loss of tensile strength of only 4.8% after a severe washing test followed by three successive treatments of chlorination and hot mealing, while a fabric finished in a similar manner, but without the protection provided by N-methylol-phthalamic acid, undergoes a loss of tensile strength greater than 34 jo.
