Definitions

• This invention relates to water-repellent textile material and to a process of manuiacturing the material and is a continuation in part of our application Ser. No. 94,482, flied August 5, 1936 l and entitled Water-repellent material and a process of manufacturing the material.
• textile materials can be made water-repellent in an advantageous manner by treating them with solutions or emulsions of 10.
• mixed polymerlzates which are prepared from maleic anhydride the free acid ora functional derivative thereoi and vinyl-esters of higher fatty acids (having at least 12 carbon atoms), Ior instance, according to the process described in U. s. Patent 2,047,398 for manufacturing mixed polymerisation products from maleic acid anhydrides and vinyl esters (see Example 4 oi the U. 8. Patent 2,047,398).
• These mixed polymerizates yield stable solutions or emulsions which,
• the mixed polymerisate from maleic anhydride and the vinyl ether of an aliphatic alcohol 80 of high molecular weight with at least 12 carbon atoms in the molecule as tree acid or a functional derivative thereof.
• These mixed polymerisates which as previously stated are obtainable according to the process described in U. 8. Patent 85 2,047,398 (see Example 6 for the manufacture of mixed polymers from maleic acid anhydride and vinyl others) or which may be obtained by mutual polymerisation of a functional derivative of maleic acid and 01 a vinyl ester or vinyl ether of high 40 molecular weight are composed of compounds of the formula:
• R1 and R2 stand for a member or the group consisting of COOH, C00, alkyl, CN, CONHz.
• X stands for R, OR or 0.0CR, R representing an aliphatic hydrocarbon radical with at least 12 carbon atoms.
• the reaction upon the textile materials is executed in the following way:
• the textile material is introduced into the solution or emulsion of the mixed polymerisate and, after drying in the air, dried for a short time at a higher temperature (at about 100 C.)
• the above described process is distinguished by the fact that the fiber is not only made waterproof when treated in this manner but that it retains its waterprootness even after repeated washing to an extent which could hitherto not be attained by any process, that is to say, the mixed polymerizates above characterized are so intimately combined with the fiber that similar to fast-dyestuffs, they irreversibly adhere to the fiber.
• a web of cotton or artificial silk is impregnated with a solution of 0.5 per cent strength of the mixed polymerisate from vinyl-octodecylether and maleic-acid-dimethylester in carbon tetrachloride or a mixture thereof with alcohol, and is dried at ordinary temperature.
• the web thus treated has a very good water-repellent effect and does not lose this property even when repeatedly washed or boiled with water.
• Loose wool is impregnated as indicated in Example 1 with a solution of the mixed polymerisate from vinyl-octodecyl-ether and maleic acid in a mixture consisting of methylene chloride and ethyl-alcohol. After drying, the wool thus treated shows an enhanced water-repelling effect which it does not lose by washing.
• a web of cotton or artificial silk is impregnated with a solution in methylene chloride of the mixed polymerisate from vinyl-stearate and the semi-ester oi maieic acid with methyl alcohol, and is dried at ordinary temperature.

• a web of viscose artificial silk is treated with a solution of 0.5% strength in alcohol and carbon tetrachloride of the mixed polymerisate from maleic acid and vinyloctodecyl-ether obtained by treating with steam the anhydride mixed polymerisate and dried for a short time.
• the fabric thus treated has a very good waterrepellent effect and does not lose this property even by washing or boiling.
• Loose spun rayon is impregnated with a solution of 2% strength in carbon tetrachloride of the mixed polymerisate from vinyl-stearate and maleic acid monomethyl ester, squeezed and dried.
• the spun rayon thus treated is very hydrophobe and does not lose this property by subsequent fulling.
• Piece goods consisting of a mixture of wool and spun rayon are impregnated with an aqueous solution of 1% strength of the pyridine salt of a mixed polymerisate from maleic acid and vinylhexadecyl ether and subjected for a short time to a heat treatment at 90 C.-l C.
• the material thus treated has a very good water-repellent effect and does not lose this property even by washing.
• a cotton fabric is impregnated by passage through a solution of a mixed polymerizate from viral stearate and maleic anhydride in methylene chloride, dried by exposure to air and heated for half-an-hour to about 100 C.
• the fabric thus treated is highly repellent to water and does not lose the property even after repeated washing with water and soap.
• a cotton or artificial silk fabric is impregnated with an aqueous emulsion of a mixed polymerizate from vinyl palmitate and maleic anhydride and worked up as indicated in Example 8. If desired the heat-treatment may be followed by a further treatment with aluminium formate, whereby the water-repelling effect is further increased. .This fabric also retains its water-repellent property after repeated washing.
