Definitions
- the present invention relates to a novel composition based on water-soluble high molecular weight acrylamide (co) polymers for sizing textile threads (or fibers).
- the invention is particularly applicable to the sizing of natural fibers, especially cotton type, possibly in the presence of artificial fibers, especially polyester.
- abrasion the action of using friction. There is ruffling of threads, formation of pilling due to friction on different pieces (lamellae, comb teeth ...), and hairiness: the tendency of the ends of the fibers to move away from the body of the yarn. It will cause interfering bridging that will give wire breaks or insertion faults by the frame vector.
- the sizing must not degrade the wire and the bath must be composed only of compatible products. Furthermore, there should not occur sizing deposits on the comb, which by hardening, could act as abrasives on the son.
- the sizing is an intermediate primer, which is eliminated following the weaving operation. It is an operation prior to the finishing of the fabric, after which the gluing is completely eliminated. This can prove to be very polluting due to the discharges generated. It is therefore interesting to have a product having good solubility for desizing.
- EP-A-262 945 and US Pat. No. 6,736,865 describe treatment products, not of individualized threads, but of finished woven fabrics.
- EP-A-262 945 thus describes a product combining an acrylamide polymer in the presence of other types of polymers to allow the fixing of the color on the previously woven fabric.
- US 6,736,865 discloses an acrylamide-based product in the presence of other components for treating finished textiles to provide wrinkling resistance and dimensional stability, especially at the time of color fixation.
- the document JP 60 258244 describes the possibility of rendering hydrophobic a sheet being formed, by treatment of papermaking fibers (and non-textile fibers) by means of a mixture of a ketene with an acrylamide polymer .
- the choice of sizing depends mainly on the nature of the chain, taking into account also the type of weaving:
- the main types of base products that can be used as sizing agents are natural or synthetic polymers which are classified as follows: - Starchy foods: starches, starches, etc.
- starch derivatives ethers, acetates ...
- cellulosic derivatives carboxymethyl, methyl and ethyl cellulose
- polyesters - acrylics they are especially suitable for synthetic and artificial yarns; but they are also found in combination with starches or cellulosics for natural fibers and mixtures thereof.
- Acrylic-type sizing agents are obtained by homopolymerization or copolymerization of different derivatives of acrylic acid or methacrylic acid with other monomers such as styrene, vinyl acetate, acrylamide, etc.
- macromolecular substances are obtained by synthesis, the physical properties of which can be varied within a very wide range. This explains the many applications in sizing different threads: polyamide, polyester, cellulosic. The main properties they bring are:
- the problem is therefore to find a new gluing product that would glue the natural fibers and / or artificial, on dry looms, and meets the requirements of the industry, that is to say: good affinity with the yarns or fibers, easy implementation (sizing speed %), improvement of the efficiency of the looms: increase of the resistance of the yarns or fibers while limiting the phenomenon of clogging of the combs,
- a sizing bath has now been found for natural and / or artificial textile fibers in the form of an aqueous solution having performance at least as good as that of pre-existing compositions but at significantly lower sizing agent dosages.
- the subject of the present invention is firstly a temporary sizing agent for naturalized and / or artificial individualized textile fibers, in particular of the cotton and / or cotton / polyester type, characterized in that it comprises a water-soluble homopolymer or copolymer of at least one acrylamide monomer having a molecular weight of at least 1 million, advantageously greater than 3 million.
- the sizing agent consists exclusively of a homopolymer or copolymer of acrylamide.
- the sizing agent of the invention is especially obtained by polymerization (or respectively copolymerization, together throughout the text and claims: "polymerization") of at least one nonionic monomer acrylamide type and possibly other ionic monomers, and advantageously has a UL viscosity greater than 3.
- the polymers of the invention do not require development of a particular polymerization process. They can be obtained by any of the polymerization techniques well known to those skilled in the art (solution polymerization, gel polymerization, precipitation polymerization, emulsion polymerization (aqueous or inverse) followed or not by a spray drying step, suspension polymerization, micellar polymerization followed or not by a precipitation step).
- the water-soluble (co) polymer serving as sizing agent is obtained from:
- anionic and / or cationic preferably 0 to 5 mol%, in the presence or absence of a branching agent and optionally a transfer agent.
- ionic monomers that can be used: cationic monomers: dialkylaminoalkyl (meth) acrylate, dialkylaminoalkyl (meth) acrylamide, diallylamine, methyldiallylamine and their quaternary ammonium or acid salts ...
- anionic monomers having a carboxylic function (eg acrylic acid, methacrylic acid, and their salts 10), the monomers having a sulphonic acid function (eg 2-acrylamido-2-methylpropanesulphonic acid (AMPS) and their salts ...) ...
- branching agents methylene bisacrylamide (MBA), ethylene glycol di-acrylate, polyethylene glycol dimethacrylate, diacrylamide, cyanomethylacrylate, vinyloxyethylacrylate or methacrylate and formaldehyde, glyoxal, glycidyl ether type such as ethylene glycol diglycidyl ether, or epoxy or any other means well known to those skilled in the art for crosslinking.
- MBA methylene bisacrylamide
- ethylene glycol di-acrylate polyethylene glycol dimethacrylate
- diacrylamide diacrylamide
- cyanomethylacrylate vinyloxyethylacrylate or methacrylate and formaldehyde
- glyoxal glycidyl ether type
- epoxy any other means well known to those skilled in the art for crosslinking.
- the invention also relates to a sizing bath comprising the sizing agent described above in a proportion of less than 2% by weight of dry matter, preferably less than 1.5% by weight.
- the present invention also relates to a sizing / de-bonding process of natural and / or artificial textile fibers consisting of immersing said fibers in the bath described above, then, after weaving, to de-stick the fibers using hot water only.
- the concentration of the sizing agent in the bath may vary within the range described above, taking into account the equipment used for carrying out the sizing cycle, in particular the squeezing power of the rolls, and the amount of glue that we want to raise on the son. It is known that this depends on the one hand on the strength of the yarns which is itself a function of their texturing, their degree of torsion, the number of strands per unit yarn and, on the other hand, the adhesion capacity. from the sizing agent to the son to be treated.
- compositions of the invention give coatings having a good protective power and a high adhesive power to textile yarns of cotton and polyester / cotton type; as a result, a concentration of less than or equal to 2% by weight, preferably less than 1.5%, of the composition is sufficient for all the cases of application, including the most difficult son to glue.
- a deposit representing a larger quantity is perfectly conceivable but it does not bring real benefits and can even be detrimental.
- Glued string yarns under the conditions of the invention have sufficient strength for subsequent dry weaving operations.

Description
NOUVELLE COMPOSITION D'ENCOLLAGE DE FILS TEXTILES NEW COMPOSITION FOR STITCHING TEXTILE YARNS
La présente invention se rapporte à une nouvelle composition à base de (co)polymères d'acrylamide hydrosolubles de poids moléculaire élevé pour l'encollage de fils (ou de fibres) textiles. L'invention s'applique tout particulièrement bien à l'encollage des fibres naturelles, notamment du type coton, en présence éventuellement de fibres artificielles, en particulier le polyester.The present invention relates to a novel composition based on water-soluble high molecular weight acrylamide (co) polymers for sizing textile threads (or fibers). The invention is particularly applicable to the sizing of natural fibers, especially cotton type, possibly in the presence of artificial fibers, especially polyester.
Dans l'industrie textile, lors des opérations de tissage, les fils ou fibres sont soumis à un travail d'extension répété. Les extensions des fils peuvent provoquer des casses. Il faut donc jouer sur la capacité d'allongement du fil dépendant de sa nature.In the textile industry, during weaving operations, the yarns or fibers are subjected to repeated extension work. Wire extensions can cause breakages. It is therefore necessary to play on the lengthening capacity of the wire depending on its nature.
En plus du phénomène d'extension, d'autres contraintes existent. Ce sont essentiellement : l'abrasion : action d'user par frottement. Il y a ébouriffage des fils, formation de bouloches dues au frottement sur différentes pièces (lamelles, dents du peigne...), - et la pilosité : la tendance qu'ont les extrémités des fibres à s'écarter du corps du filé. Elle va provoquer des pontages interfils qui donneront des casses de fils ou des défauts d'insertion par le vecteur trame.In addition to the extension phenomenon, other constraints exist. These are essentially: abrasion: the action of using friction. There is ruffling of threads, formation of pilling due to friction on different pieces (lamellae, comb teeth ...), and hairiness: the tendency of the ends of the fibers to move away from the body of the yarn. It will cause interfering bridging that will give wire breaks or insertion faults by the frame vector.
Afin de protéger les fils contre ces forces de détérioration et d'améliorer leur résistance, il est connu d'employer des produits d'encollage.In order to protect the wires against these deteriorating forces and to improve their resistance, it is known to use gluing products.
Pour obtenir de bons résultats, le choix de la colle doit se faire en tenant compte des caractéristiques suivantes :To obtain good results, the choice of glue must take into account the following characteristics:
- résistance et allongement à la rupture, - souplesse du film de colle qui doit suivre les allongements subis par le fil,- resistance and elongation at break, - flexibility of the adhesive film which must follow the elongations undergone by the wire,
- bonne adhérence au fil,
- viscosité adaptée qui est fonction des fils, une trop forte viscosité, toutefois, peut causer des difficultés en cas d'arrêt sur encolleuse.- good adhesion to the wire, - adapted viscosity which is a function of the threads, too high a viscosity, however, can cause difficulties in case of stopping on glue.
De plus, l'encollage ne doit pas dégrader le fil et le bain doit être composé uniquement de produits compatibles. Par ailleurs, il ne doit pas se produire de dépôts d'encollage sur le peigne, qui par durcissement, pourraient agir comme abrasifs sur les fils.In addition, the sizing must not degrade the wire and the bath must be composed only of compatible products. Furthermore, there should not occur sizing deposits on the comb, which by hardening, could act as abrasives on the son.
Il est à noter que l'encollage est un apprêt intermédiaire, qui est éliminé suite à l'opération de tissage. C'est une opération préalable à l'ennoblissement du tissu, à l'issue de laquelle on élimine complètement l'encollage. Celle-ci peut s'avérer être très polluante de par les rejets engendrés. Il est donc intéressant d'avoir un produit présentant une bonne solubilité pour le désencollage.It should be noted that the sizing is an intermediate primer, which is eliminated following the weaving operation. It is an operation prior to the finishing of the fabric, after which the gluing is completely eliminated. This can prove to be very polluting due to the discharges generated. It is therefore interesting to have a product having good solubility for desizing.
A l'inverse, les documents EP-A-262 945 et US 6 736 865 décrivent des produits de traitement non pas de fils individualisés, mais de textiles tissés finis.On the other hand, EP-A-262 945 and US Pat. No. 6,736,865 describe treatment products, not of individualized threads, but of finished woven fabrics.
Le document EP-A-262 945 décrit ainsi un produit associant un polymère d'acrylamide en présence d'autres types de polymères pour permettre la fixation de la couleur sur le textile préalablement tissé.EP-A-262 945 thus describes a product combining an acrylamide polymer in the presence of other types of polymers to allow the fixing of the color on the previously woven fabric.
Le document US 6 736 865 décrit un produit à base d'acrylamide en présence d'autres constituants destinés au traitement des textiles finis pour conférer une résistance au froissement et une stabilité dimensionnelle, notamment au moment de la fixation de la couleur.US 6,736,865 discloses an acrylamide-based product in the presence of other components for treating finished textiles to provide wrinkling resistance and dimensional stability, especially at the time of color fixation.
Dans le domaine du papier, le document JP 60 258244 décrit la possibilité de rendre hydrophobe une feuille en cours de formation, par traitement des fibres papetières (et non textiles) au moyen d'un mélange d'une cétène avec un polymère d'acrylamide.
Le choix de l'encollage dépend surtout de la nature de la chaîne, en tenant compte aussi du type de tissage :In the field of paper, the document JP 60 258244 describes the possibility of rendering hydrophobic a sheet being formed, by treatment of papermaking fibers (and non-textile fibers) by means of a mixture of a ketene with an acrylamide polymer . The choice of sizing depends mainly on the nature of the chain, taking into account also the type of weaving:
- tissage sec : métiers lances, projectiles, jet d'air...- dry weaving: lances, projectiles, air jet ...
- tissage hydraulique : métiers jet d'eau qui nécessite des produits insensibles à l'eau dans les conditions de tissage.- hydraulic weaving: water jet looms that require products that are insensitive to water under weaving conditions.
Les principaux types de produits de base pouvant être utilisés comme agent d'encollage sont des polymères naturels ou synthétiques qui se classent comme suit : - les amylacés : amidons, fécules...The main types of base products that can be used as sizing agents are natural or synthetic polymers which are classified as follows: - Starchy foods: starches, starches, etc.
- les dérivés de l'amidon : éthers, acétates...starch derivatives: ethers, acetates ...
- les dérivés cellulosiques: carboxyméthyl, méthyl et éthyl cellulosecellulosic derivatives: carboxymethyl, methyl and ethyl cellulose
- les polyalcool de vinyle et copolymères d'acétate de vinyle les polyesters - les acryliques : ils conviennent surtout pour les fils synthétiques et artificiels ; mais on les trouve aussi en combinaison avec des amylacés ou des cellulosiques pour les fibres naturelles et leurs mélanges.- polyvinyl alcohol and vinyl acetate copolymers polyesters - acrylics: they are especially suitable for synthetic and artificial yarns; but they are also found in combination with starches or cellulosics for natural fibers and mixtures thereof.
Les agents d'encollage de type acrylique sont obtenus par homopolymérisation ou copolymérisation de différents dérivés de l'acide acrylique ou de l'acide métacrylique avec d'autres monomères comme le styrène, l'acétate de vinyle, l'acrylamide... Par un choix et un dosage approprié des monomères, on obtient, par synthèse, des substances macromoléculaires, dont on peut faire varier les propriétés physiques dans un très grand intervalle. Ceci explique les nombreuses applications en encollage de différents fils : polyamide, polyester, cellulosiques. Les principales propriétés qu'ils apportent sont :Acrylic-type sizing agents are obtained by homopolymerization or copolymerization of different derivatives of acrylic acid or methacrylic acid with other monomers such as styrene, vinyl acetate, acrylamide, etc. In a suitable choice and dosage of the monomers, macromolecular substances are obtained by synthesis, the physical properties of which can be varied within a very wide range. This explains the many applications in sizing different threads: polyamide, polyester, cellulosic. The main properties they bring are:
* un excellent pouvoir de cohésion interbrins,* excellent cross-rib cohesion,
* des performances élevées sur métiers secs.* high performance on dry looms.
Toutefois, de nombreuses contraintes existent quant à l'utilisation des agents de collage précités. Elles sont en particulier souvent liées aux quantités requises pour
que ces colles soient efficaces ainsi qu'à leur faible activité en utilisation seule sur les fibres naturelles.However, many constraints exist as to the use of the aforementioned bonding agents. In particular, they are often linked to the quantities required for that these glues are effective and their low activity in use alone on natural fibers.
Le problème qui se pose est donc de trouver un nouveau produit d'encollage qui permettrait d'encoller les fibres naturelles et/ou artificielles, sur métiers sec, et qui satisfasse aux impératifs de l'industrie, c'est-à-dire : bonne affinité avec les fils ou fibres, mise en œuvre aisée (vitesse d'encollage...), amélioration des rendements des métiers à tisser : augmentation de la résistance des fils ou fibres tout en limitant le phénomène d'encrassement des peignes,The problem is therefore to find a new gluing product that would glue the natural fibers and / or artificial, on dry looms, and meets the requirements of the industry, that is to say: good affinity with the yarns or fibers, easy implementation (sizing speed ...), improvement of the efficiency of the looms: increase of the resistance of the yarns or fibers while limiting the phenomenon of clogging of the combs,
- élimination facile et peu polluante à l'eau,- easy and low polluting elimination with water,
- et qui, en plus, permettrait de réduire significativement les quantités d'agent d'encollage et donc le coût global de l'opération.- And which, in addition, would significantly reduce the amounts of sizing agent and therefore the overall cost of the operation.
II a maintenant été trouvé un bain d'encollage pour des fibres textiles naturelles et/ou artificielles sous forme d'une solution aqueuse présentant des performances au moins aussi bonnes que celles des compositions préexistantes mais à des dosages en agent d'encollage significativement inférieurs.A sizing bath has now been found for natural and / or artificial textile fibers in the form of an aqueous solution having performance at least as good as that of pre-existing compositions but at significantly lower sizing agent dosages.
La présente invention a tout d'abord pour objet un agent d'encollage temporaire de fibres textiles individualisées naturelles et/ou artificielles, notamment de type coton et/ou coton/polyester, caractérisé en ce qu'il comprend un homopolymère ou copolymère hydrosoluble d'au moins un monomère d'acrylamide présentant un poids moléculaire d'au moins 1 million, avantageusement supérieur à 3 millions.The subject of the present invention is firstly a temporary sizing agent for naturalized and / or artificial individualized textile fibers, in particular of the cotton and / or cotton / polyester type, characterized in that it comprises a water-soluble homopolymer or copolymer of at least one acrylamide monomer having a molecular weight of at least 1 million, advantageously greater than 3 million.
Dans un mode de réalisation avantageux, l'agent d'encollage est exclusivement constitué d'un homopolymère ou copolymère d'acrylamide.
Comme cela est bien connu de l'homme de métier, plus la quantité de colle déposée est élevée, plus le pourcentage de charge de l'eau résiduaire de l'usine de textile sera grand.In an advantageous embodiment, the sizing agent consists exclusively of a homopolymer or copolymer of acrylamide. As is well known to those skilled in the art, the higher the amount of glue deposited, the greater the percentage of load of the wastewater from the textile mill.
II a été trouvé de manière surprenante que l'obtention d'un polymère à base d'acrylamide, d'un poids moléculaire supérieur à 1 million et présentant une ionicité (cationicité et/ou anionicité) faible, en pratique inférieure à 10 moles %, de préférence inférieure à 5 moles % permettait, en particulier pour les tissus pur coton ainsi que dans le cas des fils mixtes polyester/coton, une économie importante aussi bien au niveau de la concentration du bain en agent d'encollage que lors de l'étape de désencollage.It has surprisingly been found that obtaining a polymer based on acrylamide, with a molecular weight greater than 1 million and having an ionicity (cationicity and / or anionicity) low, in practice less than 10 mol% Preferably, in particular for pure cotton fabrics as well as in the case of polyester / cotton blend yarns, a significant saving in both the concentration of the sizing agent bath and in the case of polyester / cotton blend yarns was advantageously less than 5 mol%. desizing step.
L'agent d'encollage de l'invention est notamment obtenu par polymérisation (ou respectivement copolymérisation, ensemble dans tout le texte et les revendications: "polymérisation" ) d'au moins un monomère non-ionique de type acrylamide et éventuellement d'autres monomères ioniques, et présente avantageusement une viscosité UL supérieure à 3.The sizing agent of the invention is especially obtained by polymerization (or respectively copolymerization, together throughout the text and claims: "polymerization") of at least one nonionic monomer acrylamide type and possibly other ionic monomers, and advantageously has a UL viscosity greater than 3.
Les polymères de l'invention ne nécessitent pas de développement de procédé de polymérisation particulier. Ils peuvent être obtenus par toutes les techniques de polymérisation bien connues par l'homme de métier (polymérisation en solution, polymérisation en gel, polymérisation par précipitation, polymérisation en émulsion (aqueuse ou inverse) suivie ou non d'une étape de spray drying, polymérisation en suspension, polymérisation micellaire suivie ou non d'une étape de précipitation).The polymers of the invention do not require development of a particular polymerization process. They can be obtained by any of the polymerization techniques well known to those skilled in the art (solution polymerization, gel polymerization, precipitation polymerization, emulsion polymerization (aqueous or inverse) followed or not by a spray drying step, suspension polymerization, micellar polymerization followed or not by a precipitation step).
Selon l'invention le (co)polymère hydrosoluble servant d'agent d'encollage est obtenu à partir de :According to the invention, the water-soluble (co) polymer serving as sizing agent is obtained from:
90 à 100 % molaire d'acrylamide, de préférence 95 à 100 % molaire, - 0 à 10% molaire d'au moins un monomère possédant une charge ionique90 to 100 mol% of acrylamide, preferably 95 to 100 mol%, 0 to 10 mol% of at least one monomer having an ionic charge
(anionique et/ou cationique), de préférence 0 à 5 % molaire,
en présence ou non d'un agent ramifiant et éventuellement d'un agent de transfert.(anionic and / or cationic), preferably 0 to 5 mol%, in the presence or absence of a branching agent and optionally a transfer agent.
On trouvera ci dessous une liste non limitative des monomères ioniques pouvant être utilisés : les monomères cationiques : de type dialkylaminoalkyl (meth)acrylate, dialkylaminoalkyl (meth)acrylamide, diallylamine, methyldiallylamine et leurs sels d'ammonium quaternaire ou d'acides... les monomères anioniques : possédant une fonction carboxylique (ex : acide acrylique, acide methacrylique, et leurs sels...), les monomères possédant une fonction acide sulfonique (ex : acide 2-acrylamido-2- méthylpropane sulfonique (AMPS) et leurs sels...)...The following is a nonlimiting list of the ionic monomers that can be used: cationic monomers: dialkylaminoalkyl (meth) acrylate, dialkylaminoalkyl (meth) acrylamide, diallylamine, methyldiallylamine and their quaternary ammonium or acid salts ... anionic monomers: having a carboxylic function (eg acrylic acid, methacrylic acid, and their salts ...), the monomers having a sulphonic acid function (eg 2-acrylamido-2-methylpropanesulphonic acid (AMPS) and their salts ...) ...
On trouvera ci dessous une liste non limitative des ramifiants : méthylène bisacrylamide (MBA), l'ethylene glycol di-acrylate, le polyethylene glycol dimethacrylate, le diacrylamide, le cyanomethylacrylate, le vinyloxyethylacrylate ou methacrylate et le formaldehyde, le glyoxal, les composés de type glycidyléther comme Féthylèneglycol diglycidyléther, ou des époxy ou tout autre moyen bien connu de l'homme de métier permettant la réticulation.The following is a nonlimiting list of branching agents: methylene bisacrylamide (MBA), ethylene glycol di-acrylate, polyethylene glycol dimethacrylate, diacrylamide, cyanomethylacrylate, vinyloxyethylacrylate or methacrylate and formaldehyde, glyoxal, glycidyl ether type such as ethylene glycol diglycidyl ether, or epoxy or any other means well known to those skilled in the art for crosslinking.
On trouvera ci dessous une liste non limitative des agents de transfert : alcool isopropylique, hypophosphite de sodium, mercaptoethanol, etc..Below is a non-exhaustive list of transfer agents: isopropyl alcohol, sodium hypophosphite, mercaptoethanol, etc.
L'homme de métier saura choisir la meilleure combinaison en fonction de ses connaissances propres et de la présente description, ainsi que des exemples qui vont suivre.The skilled person will choose the best combination based on his own knowledge and the present description, as well as examples that follow.
L'invention concerne également un bain d'encollage comprenant l'agent d'encollage ci-avant décrit à raison de moins de 2% en poids de matière sèche, de préférence moins de 1,5 % en poids.
La présente invention concerne également un procédé d'encollage/dé senco liage de fibres textiles naturelles et/ou artificielles consistant à immerger lesdites fibres dans le bain ci-avant décrit, puis, après tissage, à désencoller les fibres au moyen d'eau chaude uniquement.The invention also relates to a sizing bath comprising the sizing agent described above in a proportion of less than 2% by weight of dry matter, preferably less than 1.5% by weight. The present invention also relates to a sizing / de-bonding process of natural and / or artificial textile fibers consisting of immersing said fibers in the bath described above, then, after weaving, to de-stick the fibers using hot water only.
La concentration de l'agent d'encollage dans le bain peut varier dans la fourchette décrite précédemment, compte-tenu de l'appareillage employé pour la réalisation du cycle d'encollage, en particulier de la puissance d'exprimage des rouleaux, et de la quantité de colle que l'on désire faire monter sur les fils. On sait que celle-ci dépend d'une part de la résistance des fils qui est elle-même fonction de leur texturation, de leur degré de torsion, du nombre de brins au fil unitaire et d'autre part de la capacité d'adhérence du produit d'encollage aux fils à traiter.The concentration of the sizing agent in the bath may vary within the range described above, taking into account the equipment used for carrying out the sizing cycle, in particular the squeezing power of the rolls, and the amount of glue that we want to raise on the son. It is known that this depends on the one hand on the strength of the yarns which is itself a function of their texturing, their degree of torsion, the number of strands per unit yarn and, on the other hand, the adhesion capacity. from the sizing agent to the son to be treated.
Un des avantages des compositions de l'invention réside en ce qu'elles donnent des enduits ayant un bon pouvoir protecteur et un pouvoir adhésif élevé aux fils textiles de type coton et polyester/coton ; de ce fait, une concentration inférieure ou égal à 2% en poids, de préférence inférieure à 1,5 %, de la composition est suffisant pour l'ensemble des cas d'application, incluant les fils les plus difficiles à encoller.One of the advantages of the compositions of the invention is that they give coatings having a good protective power and a high adhesive power to textile yarns of cotton and polyester / cotton type; as a result, a concentration of less than or equal to 2% by weight, preferably less than 1.5%, of the composition is sufficient for all the cases of application, including the most difficult son to glue.
Un dépôt représentant une quantité supérieure est parfaitement envisageable mais il n'apporte pas d'avantages réels et peut même être préjudiciable.A deposit representing a larger quantity is perfectly conceivable but it does not bring real benefits and can even be detrimental.
Les fils de chaîne encollés dans les conditions de l'invention présentent une résistance suffisante pour les opérations ultérieures de tissage à sec. Les brins unitaires sont correctement agglomérés et l'on ne note pas d'éraillage et de casse des fils ni d'encrassage des métiers à tisser.Glued string yarns under the conditions of the invention have sufficient strength for subsequent dry weaving operations. The unitary strands are properly agglomerated and there is no evidence of scuffing and breaking wires or fouling looms.
Après le tissage, le stade de désencollage selon l'invention s'effectue à titre caractéristique avec de l'eau chaude. On termine alors par un séchage.
Les compositions d'encollage selon l'invention peuvent être préparées soit bien avant leur utilisation pour l'encollage et être stockées, soit au contraire immédiatement avant leur usage, à partir de leurs constituants.After weaving, the desizing step according to the invention is typically carried out with hot water. We then finish with a drying. The sizing compositions according to the invention can be prepared either well before their use for sizing and be stored, or on the contrary immediately before use, from their constituents.
Les exemples ci-après illustrent l'invention sans toutefois la limiter.The following examples illustrate the invention without limiting it.

Après avoir mis le polymère en solution dans de l'eau à la concentration désirée, la solution est ensuite placée sous agitation pendant quelques minutes, la composition est alors prête à être utilisée pour constituer un bain d'encollage.
On immerge dans ce bain divers chaînes de fils, que l'on essore par passage entre deux cylindres puis on les sèche.After putting the polymer in solution in water at the desired concentration, the solution is then stirred for a few minutes, the composition is then ready to be used to form a sizing bath. This bath is immersed in various chains of threads, which are wrung out by passing between two rolls and then dried.
Le tableau ci-après précise les conditions des essais réalisés :The table below specifies the conditions of the tests carried out:
C/ RésultatsC / Results
Les tissages réalisés à partir des fils précédemment décrits se font dans de bonnes conditions sans éraillage ni rupture de brins.The weavings made from the son described above are made in good conditions without stripping or strand breakage.
Après le tissage, on traite le tissu au large en le faisant passer à la déroulée dans un bain d'eau chaude à 5O0C puis on le sèche (opération de désencollage).After weaving, the fabric is treated off by unwrapping it in a bath of hot water at 50 ° C. and then dried (desizing operation).
Immédiatement après ce traitement on a procédé à la teinture des tissus par une méthode classique. Le tissu fini, séché était très souple ; il montrait, en plus, une
excellente homogénéité coloristique et une bonne solidité au lavage et à la lumière.Immediately after this treatment, the tissues were dyed by a conventional method. The finished, dried fabric was very flexible; it showed, in addition, a excellent color homogeneity and good fastness to washing and light.
A titre comparatif, on a réalisé un encollage dans des conditions strictement identiques aux précédentes mais en utilisant les produits d'encollage actuellement sur le marché de types - homopolymère d'acrylate de sodium (PM : 800.000 et 350.000) et homopolymère d'acrylamide (PM : 800.000 et 350.000).By way of comparison, a sizing was carried out under conditions strictly identical to the previous ones but using the sizing products currently on the market of types - homopolymer of sodium acrylate (MW: 800,000 and 350,000) and homopolymer of acrylamide ( MS: 800,000 and 350,000).
On a constaté que pour obtenir une aussi bonne qualité d'encollage que celle obtenue par les polymères de l'invention (pas d'éraillages et ni de ruptures de fils) sur les mêmes fibres naturelles ou mixtes, il est nécessaire d'utiliser ces polymères à des concentrations très élevées : systématiquement supérieures à 5 %, en utilisation seule, et supérieures à 3 %, lorsque d'autres agents, utilisés classiquement, tels que alcool polyvinylique, urée et/ou lubrifiant sont présents dans le bain.It has been found that in order to obtain as good sizing quality as that obtained by the polymers of the invention (no scuffing or breaking of threads) on the same natural or mixed fibers, it is necessary to use these polymers at very high concentrations: systematically greater than 5%, in use alone, and greater than 3%, when other agents conventionally used, such as polyvinyl alcohol, urea and / or lubricant are present in the bath.
D/ ConclusionD / Conclusion
Selon la présente invention, il a été découvert, de manière surprenante, que les poids moléculaires élevés des (co)polymères d'acrylamide hydrosolubles de l'invention confèrent au bain d'encollage : une nette amélioration des conditions d'utilisation : une préparation et un désencollage faciles ainsi qu'une viscosité cinématique du bain réduite (coupes de viscosité), - et une efficacité d'encollage très développée, limitant, par la même, significativement la concentration d'application du bain comparativement à celle nécessaire pour des produits de même nature chimique et de poids moléculaire inférieur.
According to the present invention, it has surprisingly been found that the high molecular weights of the water-soluble acrylamide (co) polymers of the invention give the sizing bath: a marked improvement in the conditions of use: a preparation and easy desizing as well as a reduced kinematic viscosity of the bath (viscosity cuts), and a highly developed sizing efficiency, thereby significantly limiting the concentration of bath application compared to that required for products. of the same chemical nature and of lower molecular weight.
