Description

Process for dyeing and making molded articles water-repellent from water-insoluble polymers of unsaturated compounds with an olefinic one Double bond staple fibers, webs or tapes made from water-insoluble polymers of unsaturated compounds with an olefinic double bond, e.g. B. Polymers of vinyl chloride, vinyl esters and ethers, acrylic acid esters or mixtures and conversion compounds of the same as described e.g. B. obtained by post-chlorination do not absorb any water themselves, but are wetted by rapid water. Textile goods from such fibers as yarns, woven fabrics, knitted fabrics or other shaped structures, can therefore dry out very quickly when moist, but do not have any water-repellent properties and go under quickly when placed on water. Around to make such structures water-repellent, they must, for example, after Dyeing, treated with paraffin emulsions and alumina salts. the. Here you can unpleasant changes in the dyed goods, e.g. B. Reductions in rubbing fastness or grip deterioration, occur.

It has now been found that molded structures can be made from water-insoluble Pol_vmerisaten from. unsaturated compounds with an olefinic double bond At the same time you can dye and make water-repellent if you put the structure above 5o ° C with aqueous dispersions of water-insoluble ketones, ketone alcohols, Carboxylic acid esters, carbamic acid esters or phosphoric acid. esters that at least contain an aromatic residue, and at the same time with aqueous dispersions of those that are sparingly soluble or insoluble in water, for dyeing cellulose esters in water Treated by means of suitable dyes.

According to the invention, shaped structures are obtained in one operation, which in considerable Have water-repellent properties, so are difficult to wet, and at the same time are deeply colored. So it is A good utilization of the applied amounts of dye takes place.

As compounds that are well suited for the specified method, are listed for example: ketones, such as benzophenone, benzalacetophenone, benzalacetone, Plienyli-naphthylketone, <a-Chlorbetlzoplienon, 4-Bromoacetophenone, co-Acetylacetophenon, 4, 4 = tetraethyldiaminol) enzophenone, benzoin, ketone alcohols, such as benzil, carboxylic acid esters, such as methyl and ethyl benzoate, methyl 2-n-butylaminobenzoate, methyl 2-methylaminobenzoate, 4-dimethylaminobenzoic acid methyl and ethyl ester, 4-diethylamirioberizoe "acid methyl ester, Phthalic acid dimethyl, diethyl, diamyl and diphenyl ester, phthalic acid dichloroethyl ester, Diethylene glycol dibenzoic acid ester, 1,3-dibenzoyloxybetizole, carbamic acid ester, such as Phenylcarbamic acid ethyl ester, N-ethylphenylcarbainic acid ethyl ester, phosphoric acid ester, such as tricresyl phosphate or trixylenyl phosphate.

Relatively small amounts of these water-insoluble are used Compounds, usually up to 21 /, ° 1o of the weight of the goods to be dyed. Sets of more than 4 ° 1o at higher temperatures the structure of the formed objects change something. They are used in the form of their aqueous dispersions, too their preparation expediently suitable distribution means, eg. B. Condensation compounds from ethylene oxide and alkylphenols or higher molecular weight aliphatic alcohols, Alcohol sulfonates, can be used.

It is known from British patent specification 483 242, shaped, bis 2o% plasticizing agent-containing structures made of polyvinyl acetate from aqueous Emulsions of solutions <water-insoluble acetate artificial silk dyes in softeners to color. This is intended to prevent the formation of plasticizers during the process of dyeing can be held back. It is indicated that treatment temperatures should be avoided above 5o ° C. In the present process, molded ones come in Consider structures that contain no or only small amounts of plasticizers. Such structures are made water-repellent according to the invention, and it succeeds at the same time, by using the water-insoluble compounds mentioned and the high working temperature to achieve great depths of color. According to the known way of working a significant increase in the colorability of the structures is not achieved. Examples i. 1 kg of a yarn made from post-chlorinated polyvinyl chloride is used for 1 hour at 75 ' C with the mixture of a dispersion of ao 1 amino-4-cycloliexvlaminoailtraclinon-2-caibonic acid amide in 2o liters of water and an aqueous dispersion, prepares 2o g of N-ethylphenylcarbamic acid ether and 4.o g of the condensation compound from ao mol of ethylene oxide and dodecyl alcohol, treated. After rinsing, you get a vigorous. blue coloring. 5 g of the dry Need yarn, laid on water at iS ° C. 215 minutes to sink while the untreated yarn sets within 5 1l @ t @ nten.

2. 1 kg of a yarn made of post-chlorinated polyvinyl chloride is used in one hour at 75 ° C with the mixture of a dispersion of 2o t; of the azo dye 1.Aniino-4-nitrobenzenediphenylamine in 2o 1 water and an aqueous dispersion, prepared from 15 g of 4-Dimetlivlaminobenzoesäureäthvlester and suction of the condensation compound from 2o mol Ätliylenoxyd and isooctylphenol, treated. Then it is rinsed and dried. 5 g of this bright orange color Yarn, placed on water at 16 ° C, have not set after more than 300 minutes, but only slightly wetted, while the untreated yarn sank under after 10 minutes is.

3. 1 kg of a yarn of post-chlorinated polyvinyl chloride is 1 hour at 75 ° C with the mixture of a fine dispersion of 2o g of the azo dye mentioned in Example 2 in 2o 1 of water and an aqueous dispersion, prepared from 15 g of tricresyl phosphate and 30 g of the condensation compound from dodecylplienol and 20 moles of ethylene oxide. treated, rinsed and dried. 5 g of this strong orange-colored yarn have not yet sunk after placing it on water at 18 ° C according to Zoo Minuten, while the undyed yarn, the yarn treated only with the dispersion of tricresyl phosphate and the pale orange-colored yarn dyed without the addition of tricresyl phosphate goes down in a short time.

4. 1 kg of a yarn made of post-chlorinated polyvinyl chloride is used in one hour at 55 ° C with the mixture of a fine dispersion of 2o g of the example i mentioned dyes in water and an aqueous dispersion 10 g of benzophelion and 2o g of the condensation compound of dodecyl alcohol and 2o 112o1 ethylene oxide treated. rinsed and dried. 5 g of this yarn are after Placement in water at 50 ° F after 10 minutes has not yet sunk, while the undyed fiber sets in 11th minute. 5. 1 kg of a yarn from post-chlorinated polyvinyl chloride is 1 hour at 75 ° C with the mixture a fine dispersion of 2o g of the dye mentioned in Example 1 in 2o 1 Water and an aqueous dispersion, prepared from 2o g of benzil and 40 g of one Condensation compound from dodecyl alcohol and 20 moles of ethylene oxide, treated, 5 g of the dyed goods, placed on water at 1 ° C, go. after 245 minutes under. If 20 g of benzoin are used instead of 20 g of benzil, a similar color is obtained Received goods that sink in 235 minutes when placed on water. The untreated Fiber sets in 112 minutes.
