Process and compositionB brightening of organic fibrous ates 33339 The present invention concerns a process for optically brightening organic fibre material with water soluble optical In accordance with the tion a fibrous is impregnated with an optical ening a water soluble i an organic solvent having a capacity of taking up water in an amount not exceeding by and a surfactant soluble the the solvent is removed from the treated substrate and the latter is subjected to a thermal after Optical brightening compositions suitable for use in the process of the invention are obtained by dispersing a water soluble optical brightener in an organic solvent in the presence of a surfactant soluble in the For this purpose the optical the solvent and the surfactant may be admixed under stirring or ably the optical brightener and the surfactant are first processed into a pasty composition which composition is then introduced into the solvent while In this manner a stable optical brightening dispersion is From among the large number of organic solvents only those are suitable for carrying out the process ing to the which at take up a very small of about to maximum by Examples of such solvents are gasoline such as petroleum benzene and halogen or lower substituted such as and alicyclic compounds such as tetraline and Preferred solvents are halogenated aliphatic for the solvents used for dry cleaning such as trichloroethylene and and also carbontetrachloride and the chlorinated ethanes such as and Mixtures of the above mentioned solvents may also be The optical brighteners that may be used in ance with the present invention may belong to different classes of chemical but must contain at least one solubilising group such for a sulfonic acid or carboxylic acid group which may also be in form of a or a sulfonamide Suitable which contain at one sulfonic acid carboxylic acid group or an amide group are derived from the following basic types of acids of the formula wherein for hydrogen is or of the formula wherein and for lower alk lolamino or anilino acids of the formula wherein azolyl for for the following groups IV VI of the VII for be one of the following stituents of the general formula or and for a lower group or a sulfonic acid or a carboxylic acid of the formula wherein R for an alkyl or alkoxy group and X is an or disulfonic acids of the formula vherein for an or a grou of the formula an or is hydrogen or chlorine and is a sulfonic carboxylic acid or carboxylic acid ester of the formula compounds of the formula of the formula wherein X for or Ar is is a phenyl or naphtyl radical and is preferably 1 or Oxadiasole compounds of the formula wherein A is an Those substituents in the above formulae which are not sulfonic or carboxylic groups and do not contribute to the water solubility of the brighteners are merely representative and may be replaced by otlier substituents conventional for these classes of Optical brighteners with different structures may equally well be used in the process according to the provided that they contain at least one of the mentioned water Especially suitable a for the process of the invention are those optical which contain in their molecule two water solubilizing sulfonic acid The solubility of the brightener in should be at least g Mixtures of the above mentioned brighteners may also be In order to neutralize a shift from the white shade to the region of yellow and red shades which may be observed in the substrate when using of the above sraall amounts about 1 to of shading may be incorporated in the brightening compositions according to the for the occurrence of a yellow tinge may be prevented by using a blue or violet The stuffs which can be used for this purpose are those listed in the Colour Index Edition under the numbers 44055 and As surfactants for the preparation of the persed optical brightening compositions according to the there may be used anionic or nonionic must have a satisfactory solubility in the organic solvents used in accordance with the The solubility of the surfactant in the organic solvent should not be less than Suitable representatives of such surfactants belong to the following groups of Ethers of polyhydroxy compounds such as fatty polyoxalkylated oxalkylated and aliphatic polyoxalkylated alkylphenols and polyoxalkylated captans and and also the corresponding esters of the above compounds with acids such as sulfuric or phosphoric which if also be in the form of ammonium or amine Patty acid esters of ethylene and polyethylene glycols as well as of propylene butylene glycerine or polyglycerine and and also of sugar alcohols such as polyoxalkylated carbonamidcs and Preferred surfactants from among the above groups for the monoethanolamine salt of the phosphoric acid ester the addition product from oleyl alcohol and 6 moles of ethylene the ammonium salts of the acidic sulfuric acid esters of the addition product of 17 moles of ene oxide and oleyl Any of the following addition 4 moles of ethylene oxide and 9 moles of ethylene oxide and 8 moles of ethylene oxide and or oleyl coconut fatty acid with 2 moles of diethanolamine 8 moles of ethylene oxid and 1 mole of 15 or 6 moles of ethylene oxide and castor 20 moles of ethylene oxide and the alcohol ethylene oxide and polyethylene or lycol 15 or of ethylene oxide and 1 mole of an amine oleic oleic 1 mole oleic acid and 4 or 5 moles of ethylene 4 moles of ethylene oxide and 1 mole of oleic acid sorbitan or the sodium salt of the sodium salt of the phosphoric acid ester of the addition product of 5 moles of ethylene oxide and Also mixtures of the above surfactants may be The process according to the invention is an pregnation process which means that the fibrous substrate to be impregnated is sprayed or covered with a layer of the brightening composition according to the The composition of the optical brightening sitions according to the invention depends on the desired brightening effect and on the nature of the concentration of the optical brightener vary within large limits and may be from about to about 20 g of the The amount of surfactant may accordingly vary from about 1 to about 30 preferably from about 2 to 10 The amounts of optical brightener and surfactant to be used are correlated to each meaning that if the amount of optical brightener is increased the required amount of surfactant also The relative weight proportion of optical brightener to factant is preferably within the range of Q to The optical brightener and surfactant are then compounded while stirring with an organic solvent in a to yield 1 liter unit doses and in this way a stable brightening composition is In view of the fact that the brightening process is carried out in an organic there is lacking water which is required for the swelling of the fibres to facilitate the penetration of the brightener into the fibre and thereby the distribution of the brightener needed for obtaining a level Therefore it is recommendable to add swelling agents to the brightening for when the substrate is a synthetic fibrous Examples of swelling agents that may be used in the process according to the invention organic acids such as sulfonic and dronaphthalene sulfonic alcohols and polyhydroxy for ethyleneglycol and higher anolecular for and and inorganic acids such as phosphoric and boric and also chloroalhydrate and e th lenechlorhyd Inorganic acids can be used to a limited extent only since the fibres may be The swelling agents are an amount of from to 20 preferably from 2 to 5 substrates which are treated by the process according to the invention are natural or synthetic organic fibrous in particular textiles from synthetic wool and cellulosic
