Description
5~2 La presente inventlon a pour objet un procede de nettoyage à sec et de desensimage des textiles, dans le but d'empêcher les alissures de se redeposer sur un substrat en fibres naturelles, artificielles, synthetiques ou en un melange de ces mêmes fibres et ainsi, maintenir en suspension dans le bain liquide au cours du nettoyage ou du desensimage, les salissures de ce substrat.
L'invention a egalement pour objet une composition à base de perchlorethylène pour le nettoyage à sec et le desensimage des textiles, dans le but d'empêcher les salissures ' d'un substrat de se redeposer sur ce substrat.
Il est bien connu que lors des opérations de nettoyage à sec ou de desensimage au moyen de perchlorethylène, de textiles tisses ou tricotes, les salissures extraites des textiles ont .
tendance à se redeposer sur ces mêmes textiles, surtout lorsque le perchloréthylène n'est pas regenere régulièrement, ce qui ~ -accentue le phenomène de "grisage" des textiles, plus facilement observé sur des tissus blancs ou de teintes claires.
Les facteurs pouvant intervenir sur cette redéposition `~
sont multiples et la complexité du phénomène depend principale- -- ment de la diversite des fibres mises en oeuvre dans le même .- :
bain de nettoyage, et de l'hygrometrie de l'atmosphère ambiante. `-~
~ivers agents d'anti-redeposition ont déj~ éte -proposes pour le lavage des textiles en milieu aqueux, en particulier des derives de la cellulose.
Pour le nettoyage en milieu solvant organique, il est connu que certains renforcateurs ont une action anti-redepo- `
sition, en particulier les oxazines et amides substitues à
plus de 10 atomes de carbone decrits dans le brevet franQais no 1 386 783 et son addition no 89 341.
Cependant, ces renforçateurs, que ce soit ceux employes en milieu organique ou ceux en milieu aqueux, presen-tent l'inconvenient majeur de ne pas être distillables et doivent donc être rajoutés après chaque opération de régénération ' du solvant souillé.
La présente invention a pour but d'éviter la redeposition et de limiter ainsi tres considérablement le -`
phenomène de "grisage" au cours du nettoyage à sec ou du desensimage de textiles en fibres synthetiques, artificielles, naturelles ou melangees, tout en rendant recuperable et reutilisable l'agent anti-redeposition de l'invention puisque celui-ci et le perchlorethylène distillent à chaque regene-ration du bain.
La Demanderesse a trouve, de façon surprenante, qu'on pouvait très substantiellement reduire la redeposition de salissures par la mise en oeuvre, dans le perchlorethylène convenablement stabilise, d'au moins un nitrile choisi dans le groupe de ceux presentant un point d'ebullition inferieur`ou egal à 130C sous pression normale, et de ceux formant avec le perchloréthylène un azéotrope dont la température d'ébullition ~ ' est inférieure ou égale a 130C.
L'invention a donc pour objet un procédé d'anti-redeposition de salissures lors du nettoyage a sec, ou du desensimage'a l'aide de perchlorethylene convenablement stabilise, procede caracterise par le fait que pour observer ;
l'effet cherche de limitation du phenomene de "grisage" des textiles, on ajoute au perchlorethylene stabilise et/ou au bain -de nettoyage à sec ou de desensimage, une quantité suffisante ;
d'au moins un nitrile choisi dans le groupe de ceux presentant un point d'ebullition ne depassant pas 130C et, de preference, de 95 a 120C, et ceux formant avec le perchlorethylène un '~
azeotrope dont la temperature d'ebullition est inferieure ou egale - 8 130C et de preference superieure à 80 C. ~
De tels nitriles peuvent être choisis parmi ceux ~ ' representes par la formule generale:
R - C-N ~ 5 ~ 2 The present invention relates to a method of dry cleaning and sizing of textiles for the purpose prevent fouling from redepositing on a substrate natural, artificial, synthetic or mixed fibers of these same fibers and thus keep it suspended in the liquid bath during cleaning or desensing, the soiling of this substrate.
The subject of the invention is also a composition based on perchlorethylene for dry cleaning and desizing of textiles, in order to prevent soiling ' of a substrate to redeposit on this substrate.
It is well known that during cleaning operations dry or desensing using perchlorethylene, textiles fabrics or knits, dirt extracted from textiles has.
tendency to redeposit on these same textiles, especially when perchlorethylene is not regularly regenerated, which ~ -accentuates the phenomenon of "graying" of textiles, more easily observed on white or light-colored fabrics.
The factors that can influence this redeposition `~
are multiple and the complexity of the phenomenon depends mainly- -- ment of the diversity of fibers used in the same .-:
cleaning bath, and the humidity of the ambient atmosphere. `- ~
~ various anti-redeposition agents have already been ~
proposed for washing textiles in an aqueous medium, especially cellulose derivatives.
For cleaning in organic solvent medium, it is known that certain reinforcers have an anti-redepo-sition, in particular the oxazines and amides substituted for more than 10 carbon atoms described in the French patent no 1,386,783 and its addition no 89,341.
However, these reinforcers, whether those used in an organic medium or those in an aqueous medium, present try the major drawback of not being distillable and must therefore be added after each regeneration operation ' soiled solvent.
The object of the present invention is to avoid the redeposition and thus very considerably limit the -`
phenomenon of "graying" during dry cleaning or sizing of textiles made of synthetic and artificial fibers, natural or mixed, while making it recoverable and reusable the anti-redeposition agent of the invention since this and perchlorethylene distill at each regeneration bath ration.
The Applicant has surprisingly found that we could very substantially reduce the redeposition of soiling by use, in perchlorethylene suitably stabilized, of at least one nitrile chosen from the group of those with a lower boiling point or equal to 130C under normal pressure, and of those forming with the perchlorethylene an azeotrope whose boiling point ~ ' is less than or equal to 130C.
The subject of the invention is therefore a method of anti redeposition of dirt during dry cleaning, or sizing using suitable perchlorethylene stabilizes, process characterized by the fact that to observe;
the effect seeks to limit the phenomenon of "graying" of textiles, added to stabilized perchlorethylene and / or to the bath -dry cleaning or sizing, a sufficient amount;
at least one nitrile chosen from the group of those having a boiling point not exceeding 130C and, preferably, from 95 to 120C, and those forming with perchlorethylene a '~
azeotropic whose boiling point is lower or equal - 8 130C and preferably greater than 80 C. ~
Such nitriles can be chosen from those ~ ' represented by the general formula:
R - CN ~
- 2 - ~' ~P2S;~Z
dans laquelle R peut représenter un groupe alkyle en Cl-C5,-alcenyle en Cl-C6 ou cycloalkyle en C3-C5.
Lleffet recherche d'anti-redéposition est observé
en mettant en oeuvre des proportions qui peuvent carier suicant le nitrile considéré. En général, les nitriles les plus efficaces comme l'acétonitrile et le propionitrile, exercent un effet appré-cia~le d'anti-redéposition à partir d'une teneur de 0,2~ en poids dans le perchloréthylène, alors que pour d'autres, comme le chlo-racétonitrile, l'effet optimum est observé à des teneurs d'envi-ron 6% en poids. On préfère, toutefois, mettre en oeuvre des nitriles dont l'effeL devient appréciable ou optimum à des teneurs ~ -comprises entre 1 et 2,5~ en poids dans le perchlorethylène.
Le perchloréthylène peut être stabilisé par tout agent de stabilisation approprié, en particulier ceux compatibles avec la présence des nitriles definis ci-dessus, et tels que, entre ;-autres, et sans q~e la liste suivante de composants soit limita-tive: l'oxyde de butylene, la triethylamine, le tertiobutanol/ le N-methylpyrrole, le n-butanol, le diisobutylene, l'acetate d'iso- ` `
propyle, et l'epichlorhydrine, pris separement ou en melange d'au .;, moins deux de ces composes.
Le procede d'anti-redeposition, selon l'invention, peut egalement comprendre l'adjonction de produits couramment employes en netto~age à sec, comme par exemple des renforcateurs de net-toyage representes par des tensio-actifs anioniques, cationiques, ou non-ioniques, tels que: des alkylsulfonates, des alkylarylsul~
fonates, plus particulièrement le dodecyl benzène-sulfonate de Ca, des produits d'ethoxylation d'alcools gras et d'acides gras, des sulfatès d'alcools gras, des sulfonates de pétrole, des alcoylpo- -lyglycoléthers, des polyglycoléthers d'alcoylphenol, plus parti-culièrement le nonylphenol oxyethyléné à 12 moles dioxyde d'éthy- ~
lène, des agents d'avivage, des apprêts, des agents anti-statiques ~;
et des agents d'hydrogugation. Chacun de ces additifs peut être mis en oeuvre dans les f - 2 - ~ ' ~ P2S; ~ Z
in which R can represent a C1-C5 alkyl group, -C1-C6 alkenyl or C3-C5 cycloalkyl.
The search for anti-redeposition effect is observed by implementing proportions that can sucking carier the nitrile considered. In general, the most effective nitriles like acetonitrile and propionitrile, exert an appreciable effect cia ~ the anti-redeposition from a content of 0.2 ~ by weight in perchlorethylene, while for others, such as chlo-racetonitrile, the optimum effect is observed at levels of approx.
6% by weight. We prefer, however, to implement nitriles whose effeL becomes appreciable or optimum at levels ~ -between 1 and 2.5 ~ by weight in perchlorethylene.
Perchlorethylene can be stabilized by any agent appropriate stabilization, especially those compatible with the presence of the nitriles defined above, and such that, between; -others, and without q ~ e the following list of components is limited to tive: butylene oxide, triethylamine, tertiobutanol /
N-methylpyrrole, n-butanol, diisobutylene, iso- acetate '' propyl, and epichlorohydrin, taken separately or as a mixture of .;, minus two of these compounds.
The anti-redeposition method according to the invention can also include the addition of commonly used products in dry cleaning, such as net reinforcers toy represented by anionic, cationic surfactants, or nonionic, such as: alkylsulfonates, alkylarylsul ~
fonates, more particularly Ca dodecyl benzene sulfonate, ethoxylation products of fatty alcohols and fatty acids, sulfates of fatty alcohols, petroleum sulfonates, alkylpo- -lyglycol ethers, polyglycol ethers of alkylphenol, more particularly especially the oxyethylenated nonylphenol containing 12 moles of ethyl dioxide ~
lene, brightening agents, primers, anti-static agents ~;
and hydrogugating agents. Each of these additives can be implemented in f
- 3 -5~
proportions habituelles, par exemple de 1 à 10 g par litre de bain dans la mesure o~ il est compatible avec la présence des nitriles de l'invention tels que définis ci-dessus.
En outre, le procédé de l'invention peut comprendre l'apport d'eau en proportions qui peuvent aller jusquià
environ 5-6%, et plus particulièrement de 2 à 3% en poids par rapport aux textiles à nettoyer. Cette eau peut provenir de l'humidité apportée par les textiles eux-mêmes, et/ou par les renforçateurs de nettoyage du commerce qui contiennent entre 4 et 30% et, habituellement, de 8 a 14% de leur poids d'eau. Parfois on additionne des quantités supplémentaires d'eau (environ 2 a 4% en poids par rapport aux textiles a nettoyer) au bain de nettoyage contenan-t les renforcateurs afin d'améliorer l'effet de nettoyage vis-a-vis des souillures dites "maigres". ~
L'invention a également pour objet une composition ou --un bain utile dans le nettoyage a sec, ou le desensimage des textiles pour empêcher le "grisage" ou la redéposition des salissures sur les textiles en fibres naturelles, artificielles, synthétiques ou mélangées, au cours meme des opérations de nettoyage a sec ou de desensimage, a l'aide de perchlorethylene convenablement stabilise, contenant éventuellement de l'eau jusqu'a 6~ en poids par rapport aux textiles a traiter et des additi~s usuels, plus particulierement des renforçateurs de nettoyage et des agents anti-statiques, chacun de ces additifs pouvant être présents, a raison de 1 à 10 g par litre de ladite composition, laquelle se caracterise par le fait qu'elle contient, outre le perchlore-thylène et ses agents de stabili- `
sation appropriés, de 0,2 à 6% et, de préférence, entre 1 et 2,5% en poids par rapport a ladite composition dlau moins un nitrile choisi dans le groupe de ceux presentant un point d'ebullition inférieur ou ~gal à 130C et, de préference, de 95 à 120C, et de ceux formant avec le perchlorethylène un - 3 -5 ~
usual proportions, for example from 1 to 10 g per liter of bath insofar as it is compatible with the presence of nitriles of the invention as defined above.
In addition, the method of the invention may include the supply of water in proportions which can go up to about 5-6%, and more particularly from 2 to 3% by weight per compared to textiles to be cleaned. This water can come from the humidity provided by the textiles themselves, and / or by commercial cleaning boosters that contain between 4 and 30% and usually 8-14% of their weight of water. Sometimes we add additional quantities of water (approximately 2 to 4% by weight relative to textiles with clean) in the cleaning bath contains the reinforcers to to improve the cleaning effect vis-à-vis soiling "skinny". ~
The subject of the invention is also a composition or -a bath useful in dry cleaning, or the desensing of textiles to prevent "graying" or redeposition of soiling on textiles made of natural and artificial fibers, synthetic or mixed, even during the operations of dry cleaning or desizing, using perchlorethylene suitably stabilized, possibly containing water up to 6 ~ by weight relative to the textiles to be treated and usual additives, more particularly reinforcers of cleaning and anti-static agents, each of these additives may be present, at a rate of 1 to 10 g per liter of said composition, which is characterized by the fact that it contains, in addition to perchlore-thylène and its stabilizers from 0.2 to 6% and preferably between 1 and 2.5% by weight relative to said composition of at least a nitrile chosen from the group of those presenting a point lower boiling point or ~ gal at 130C and preferably 95 at 120C, and of those forming with perchlorethylene a

Le nitrile peut etre choisi parmi ceux représentés : par la formule générale:
R - C~N
dans laquelle R est défini comme indiqué ci-dessus.
A titre d'exemples de nitriles répondant a cette formule -::
generale, on peut citer, entre autres, les compos~s suivants pris separement ou en mélange, d'au moins deux d'entre eux:
acétonitrile, butène-3 nitrile, cis et trans-crotononitrile, butyronitrile, iso~utyronitrile et valéronitrile.
Selon une forme préferee de realisation de l'invention, , .
on met en oeuvre en tant que nitrile le propionitrile. ~-- Le mode operatoire permettant d'evaluer le "grisage"
des textiles a éte effectué a l'aide d'une salissure représenta- ~
tive de la salissure habituellement présente sur les vetements et -~ .
ayant la composition pondérale suivante~
- poussière de battage de tapis tamisee a 26 mesh (mailles de ~ :
0,63 mm) 100 ~.
: 20 - huile de vidange de~moteur d'automobile 100 - noir de fumee broye dans son poids d'huile moteur S A E 30 ~ 4 ;~
- huile de ricin oxyethylenee a 10 molécules d'oxyde d'ethylene 5 - eau distillée 50 - - perchlorethylene stabillse 155 .~ -Les echantillons de textiles blancs utilisés ont été
les suivants: ~
- polyester 100~ a 268 g/m2 - polyamide 6-6 100% à 170 g/m2 - polyacrylonitrile 100% à 220 g/m2 ~ :
- laine 100~ à 280 g/m2 - coton 100~ à 110 g/m2 ~.
D;Z5~
Afin d'évaluer le "grisage" des textiles, on a place dans une machine à tambour de laboratoire successivement:
- 225 cm2 de chacun des echantillons de textiles precites;
- 1 litre de la composition à base de perchlorethylène stabilise dans lequel on a dispersé 0,5 g de la salissure definie ci-dessus.
Apr~s traitement durant 5 minutes a environ 25 C, les textiles ont ete ~ssores et seches à 60C en etuve ventilee.
Chacun de ces echantillons ainsi traites et plus ou moins "grises" a eté soumis à une détermination de l'indice de reflectance a l'aide du "Reflectionmeter 670" de la Compagnie "Photovolt" (Etats-Unis d'Amerique) equipe du filtre vert.
- On a réglé l'appareil à 100 pour chaque textile d'ori-.
gine non traité, et on a mesure la reflec~ance de chaque échantillon "grise". Le grisage est d'autant plus faible que la reflectance est plus proche de 100. - -~
Les exemples suivants illustrent les divers aspects de l'invention, de façon non limitative, les pourcentages indiques des constituants de chaque composition etant exprimes en poids par rapport a la composition consideree.
Dans tous les exemples, il est fait reference, à titre de temoins, aux mesures d'indice de reflectance d'echantillons de textiles traites dans les mêmes conditions avec le perchlore~
thylene stabilisé, mais ne contenant pas l'agent anti-redeposi-tion objet de la presente invention.
EXEMPLES 1 à 10 En procedant selon le mode operatoire expose ci-dessus, on a examine l'effet "anti-grisage" ou anti-redéposition d'une composition à base de perchlorethylène initialement stabilisé ~
auquel on a incorporé différentes proportions de divers nitriles. ~, Le perchloréthylène de depart etait stabilisé par 0,0025~ de triéthylamine, 0,002~ de N-methylpyrrole et de 5 ~ 2 azeo-trope with a boiling point less than or equal to ~
130C and preferably higher than 80C. .
The nitrile can be chosen from those shown : by the general formula:
R - C ~ N
in which R is defined as indicated above.
As examples of nitriles corresponding to this formula - ::
general, we can cite, among others, the following compounds:
taken separately or as a mixture, from at least two of them:
acetonitrile, butene-3 nitrile, cis and trans-crotononitrile, butyronitrile, iso ~ utyronitrile and valeronitrile.
According to a preferred embodiment of the invention, ,.
propionitrile is used as the nitrile. ~ -- The operating mode allowing to assess the "graying"
textiles was carried out using a representative soiling ~
tive dirt usually present on clothing and - ~.
having the following weight composition ~
- carpet threshing dust sieved to 26 mesh (~ mesh:
0.63 mm) 100 ~.
: 20 - automobile engine oil drain 100 - black smoke smashed in its weight of engine oil SAE 30 ~ 4; ~
- oxyethylenated castor oil with 10 oxide molecules ethylene 5 - distilled water 50 - - perchlorethylene stabillse 155. ~ -The white textile samples used were the following: ~
- polyester 100 ~ a 268 g / m2 - polyamide 6-6 100% at 170 g / m2 - 100% polyacrylonitrile at 220 g / m2 ~:
- wool 100 ~ to 280 g / m2 - cotton 100 ~ to 110 g / m2 ~.
D; Z5 ~
In order to assess the "graying" of textiles, we place in a laboratory drum machine successively:
- 225 cm2 of each of the textile samples above;
- 1 liter of the composition based on perchlorethylene stabilizes in which 0.5 g of the defined dirt has been dispersed above.
After treatment for 5 minutes at around 25 C, the textiles were dry and dry at 60C in a ventilated oven.
Each of these samples thus processed and more or less "gray" was subjected to a determination of the index of reflectance using the Company's "Reflectionmeter 670"
"Photovolt" (United States of America) fitted with the green filter.
- The device was set to 100 for each ori- textile.
untreated gine, and we measured the reflectance of each "gray" sample. The graying is all the weaker as reflectance is closer to 100. - - ~
The following examples illustrate the various aspects of the invention, without limitation, the percentages indicated constituents of each composition being expressed by weight in relation to the composition considered.
In all the examples, reference is made to of witnesses, to the samples reflectance index measurements textiles treated in the same conditions with perchlore ~
stabilized thylene, but not containing the anti-redepositive agent tion object of the present invention.
EXAMPLES 1 to 10 By proceeding according to the operating mode described above, we examined the "anti-graying" or anti-redeposition effect of a composition based on perchlorethylene initially stabilized ~
to which different proportions of various nitriles have been incorporated. ~, The starting perchlorethylene was stabilized by 0.0025 ~ of triethylamine, 0.002 ~ of N-methylpyrrole and
