While in earlier times dyestuffs or other finishing chemicals were applied to textile fabrics in aqueous solution only, there has recently been an increasing tendency to use organic solvents for this purpose. Apart from various other advantages, organic solvents have the feature of excellent penetration properties, which enable the dyestuff (or other finishing chemical) to be uniformly applied with a relatively small amount of solvent. A reduction of the amount of solvent is desirable because of the consequent reduction of the scale of drying (for subsequent vaporisation of the solvent), the lesser size of the plant, the shortening of the drying period and above all because of the reduced risk of migration (the tendency of the dyestuff to move in the textile fabric).
However the use of organic solvents also involves certain difficulties. In view of their relatively high price, the evaporated solvents are normally recovered. Apart from the considerable cost involved in this operation, the necessity for recovery also considerably limits the type of organic solvent that can be used. This again means that special dyestuffs have to be developed for the recoverable organic solvents concerned. A further disadvantage is that the recovery plant must in each case be adapted to the solvent used, so that dyeing plants cannot necessarily be operated with different solvents.
The invention is therefore based on the problem of providing a method of the type initially mentioned which avoids these defects and wherein the difficulties associated with the recovery of organic solvents are overcome, the use of standard dyestuffs is largely possible, and existing plants can be converted without difficulty to different dyes and solvents.
According to the invention this problem is solved in that the organic solvents used comprise only materials which can be converted by oxidation into carbon dioxide and water, and in that the organic solvents when vaporised again after application are catalytically burned, either immediately or after prior enrichment.
Since with organic solvents a uniform dyeing can be achieved even when using a very small amount of solvent, it is economically reasonable to burn catalytically the organic solvents when vaporised again after being applied. If only materials which can be converted by oxidation into carbon dioxide and water are chosen for the organic solvents, these ecologically acceptable products can be discharged without difficulty into the environment.
The renunciation in accordance with the invention of the recovery of vaporised organic solvents opens up considerable possibilities. On dropping the limitative condition of capacity for recovery, there now exists a disproportionately greater freedom '11 the choice of organic solvent, solvent mixtures, or mixtures of solvents and water which can be used. In particular the last alternative permits use of many of the already existing dyestuffs, based on aqueous ,solvents, already developed by the chemical industry.
A further advantage is that with the method according to the invention the devices for catalytically burning the vaporised solvent need no particular adaptation to the solvent or solvent mixture used. Dyeing plants operating according to the method can therefore be converted without difficulty to different dyestuffs and solvents.
Organic solvents which fulfil the above conditions include in particular aliphatic and cyclic hydrocarbons, alcohols, esters, ethers, ketones, aldehydes and lowmolecular weight organic acids.
A maximum of 50% by volume of solvent (i.e., a maximum of 500ml of solvent per 1000g of fabric) is preferably used with the method provided by the invention and the dyestuff or other finishing chemical is applied in 20 40% of the volume of solvent. If, however, a mixture of at least the organic solvent with water is used for applying the dyestuff or other finishing chemical, it is economically feasible to use more than 50% by volume of solvent.
What is claimed is:
l. A method of applying to a textile fabric a finishing chemical such as dyestuffs, said method comprising applying to said fabric a liquid mixture containing said chemical and organic solvent in a maximum amount of 500 ml solvent per 1000 g of fabric, said solvent being capable of removal from said fabric by vaporisation and constituting only one that can be converted by oxidation into carbon dioxide and water; vaporising said solvent following application thereof to said fabric; and burning said vaporised solvent.
