Definitions
- This process is performed with preparations containing a water-insoluble organic solvent, a reaction product and a surface-active dispersing agent which is soluble in the organic solvent.
- the reaction products are either of a basic polyamide and an epoxide, aminoplast precondensate ether or epoxide-polymeric fatty acid reaction product, or of an epoxide-organic acid reaction product and an amine or amine-epoxide reaction product.
- the textiles may be subjected to an after-treatment at room temperature or elevated temperaure. Preferably this process is carried out according to the exhaustion method. Good and during non-felting effects are obtained on the treated textiles.
- the subject of the invention is a process for the finishing of textiles, especially for rendering wool non-felting, characterised in that textiles are treated with a preparation which (1) in a water-insoluble organic solvent, contains (2) a reaction product of (a) (a') a basic polyamide and (a") an epoxide, an alkyl ether of an aminoplast precondensate or an epoxide-polymeric unsaturated fatty acid reaction product, or (b) (b') an epoxide-organic carboxylic acid reaction product and (b") an amine or amino-epoxide reaction product and (3) a surface-active dispersing agent which is soluble in organic solvents, that the solvent is subsequently removed from the textiles thus treated, and that thereafter the textiles, if desired, are subjected to an after-treatment at room temperature or at elevated temperature.
- the exhaustion process is here used.
- the preparation for the non-felting treatment is allowed to act on the textiles for 15 to 60 minutes at a temperature of to 80 C., preferably to C.
- An addition of a low molecular aliphatic carboxylic acid, such as for example formic acid or acetic acid, to the treatment bath at a concentration of up to 20 mL/Iitre has proved useful in many cases, especially in the case of a combined application together with optical brighteners.
- the textiles are subjected to an after-treatment, for example by storing at room temperature for 2 to 10 days or to a heat treatment at preferably 40 to 200 C., especially 80 C., for 60 to 15 minutes, especially 60 minutes.
- the preparation which is used for the finishing can contain yet further additives, such as for example other textile finishing agents, for example optical brighteners or agents for imparting a soft handle.
- the wool to be finished can be in any desired state of processing, for example in the form of slubbing, yarn or garments, such as pullovers.
- Dyeing can here be carried out in the usual manner which is in itself known, using any desired dyestuffs which can be used for wool.
- the additives which are customary in dyeing Wool can be employed, such as levelling agents, for example polyglycol compounds of higher aliphatic amines.
- the amount of the reaction product (2) (not including solvent), relative to the weight of the wool, is appropriately 0.5 to 5%, preferably 1.2 to 3%.
- sequence of the two processes is optional, but in general it tends to be advantageous to carry out dyeing first and the non-felting treatment subsequently, though it is also possible to carry out dyeing and the non-felting treatment simultaneously using the same bath.
- water-soluble solvents can be used for carrying out the present process, that is to say solvents which at 20 C. only take up very small amounts of water, for example 0.01 to 1% by weight.
- the following are for example suitable: petrol hydrocarbons, such as petrol ether; benzene and halogenated benzenes or benzenes substituted by lower alkyl groups, such as toluene, ethylbenzene, cumene or xylene; alicyclic hydrocarbons such as Tetralin or cyclohexane; or, especially, halogenated aliphatic hydrocarbons.

- Particularly suitable fatty acids are dimerised to trimerised linoleic acid or linolenic acid.
- the technical products of these acids as a rule contain 75 to by Weight of dimeric acid, 4 to 25 percent by weight of trimeric acid and from a trace to 3% of monomeric acid.
- the molar ratio of dimeric to trimeric acid is accordingly about 5:1 to 36:1.
- the basic polyamides are obtained by condensation of these polymeric fatty acids, especially of the dimerised to trimerised linoleic or linolenic acid, with polyamines, especially aliphatic polyamines such as diethylenetriamine, triethylenetetramine and tetraethylenepentamine, that is to say amines of formula wherein n is equal to 1, 2 or 3 and can, in the case of mixtures, also assume a non-integral average value, for example between 1 and 2.
- polyamides must be basic, and this is achieved by employing an excess of amino groups (HgN- and alkylene-NH-alkylene) in comparison to the carboxylic acid groups during the polyamide condensation.
- aminoplast precondensates which serve as starting substances for the manufacture of the reaction products of type 2 are completely, or especially partially, etherified methylol compounds of nitrogen-containing substances which form aminoplastics, such as urea and urea deriva tives, for example ethyleneurea, propyleneurea and glyoxalrnonourein.

- the amine can now be employed by itself or as a reaction product with an epoxide, for the manufacture of reaction products of type 3.
- the same epoxides can be used as are employed for the manufacture of the reaction products with the organic carboxylic acids or of the reaction products of type 1. Since the equivalent ratio of amino groups to epoxide groups in component (b") is 3 to 5.5 to 1, the amino groups are always present in excess, and epoxide groups can no longer be detected in the amine-epoxide reaction product (b").
- the epoxides used for the manufacture of the component (b") therefore do not influence the equivalent ratio of epoxide groups to hydrogen, bonded to amine nitrogen, of 1:2 to 1:10 in the end product from components (a) and (b).
- the epoxides are reacted with the basic polyamides in the equivalent ratio of 1:1 to 1:5.

- the aminoplast precondensates are reacted with the basic polyamides in the equivalent ratio of 1:0.11 to 1:1.45 when manufacturing the reaction products of type 2.
- an equivalent is to be understood as the quotient of the molecular weight and the total number of methylol groups (free plus etherified) present in the molecule.
- the amount of basic polyamide equivalent to one mol of monoamine corresponds to one amino equivalent.
- one mol of methylol compound containing an average of 5.5 (partially etherified) methylol groups is reacted with the amount of basic polyamide corresponding to 0.6 to 8 amino equivalent values.

- Dioxane, isopropanol, ethanol and methanol, ethylene glycol-n-butyl ether (:n-butylglycol) and diethylene glycolmonobutyl ether may be mentioned as examples.
- anionic or non-ionic surface-active compounds are advantageously used, it being necessary to ensure that these possess good solubility in the organic solvents which are used for the finishing process. Addition products of ethylene oxide to long-chain amines,

- the preparations to be used according to the invention are appropriately prepared by stirring the reaction products into the water-insoluble organic solvent in the presence of the dispersing agent.
- the reaction product which is preferably obtained as an organic solution when manufactured, is dissolved or diluted, before being dispersed, by means of a polar solvent such as a lower alkanol, for example ethanol or especially methanol. Stable dispersions are thereby always obtained.
- the initially mentioned addition of low molecular carboxylic acids to the treatment bath is preferably made before the addition of the reaction product.
- a further possibility consists of first working the reaction product into a dough with the surface-active agent and then to introduce this into the water-insoluble solvent, whilst stirring.
- the process has the advantage that it is carried out in the weakly acid to neutral range and not in the alkaline range.
