Definitions

• a suitable emulsion can for instance very easily be prepared if to the anhydride, if desired a molten anhydride of a high molecular fatty acid, that is to say, a fatty acid with more than 10 carbon atoms, there is added 50 times its quantity of a 0.75% soap solution at 75 (1, and the mixture is energetically stirred for a few minutes and subsequently diluted with the same quantity of warm water.
• the textile material to be treated is then immersed in 'such'an emulsion in a suitable apparatus, squeezed ofi, dried, and
• White cotton twill is treated with this emulsion; 10 the material is then squeezed. oif, dried in the usual manner and treated at about 80 C. for hour; the soap is then removed by. rinsing, and the material is dried in the usual manner.
• Example 2 Print woven material made of 5 artificial silk is treated in. the same manner as described in Example 1.
• Example 3 --Knitted fabric made of wool and staple fibres is treated as described in Example 1, but is exposed only for 15 minutes to a temperature of 80 C.
• Example e f-Cotton goods made of cotton which'has not been bleached and not been kierboiled, are impregnated with an emulsion prepared according to Example 1, dried, exposed for 25 20 minutes to a temperature of about 150 0., and after this ripening process they are rinsed with water and again dried.
• the process may be slightly simplified in some cases, particularly in case that the soap smell carried along with the goods after impregnating and drying is not inconvenient. In such cases rinsing of the soap is not necessary, and the process is finished when the goods have been impregnate'd and dried. Indeed it has been found that if soap and anhydrid remain within the textile goods the water repelling efiect gradually occurs, for instance after twenty-four hours, even if the goods are not longer exposed to an in- 40 creased temperature after drying. It will be understood that the soaps to be used with the said manner of carrying out the process should be as inodorous as possible.
• a process of rendering textiles repellent to water which includes the steps of treating the same with an emulsion of an anhydride of high molecular fatty acid in an aqueous solution of a stable soap, and heating for substantially 15 to minutes to a temperature of substantially to 150 degrees C., the said soap being characterized in stability by its resistance to decomposition at the temperature of heating.
• a process 01 rendering textiles repellent to water which includes the steps of treating the same with an emulsion of an anhydride of a high molecular fatty acid in an aqueous solution of an alkali metal soap, and heating for substantially 15 to 60 minutes to a temperature of 70 to 150 degrees C., the said soap being characterized in stability by its resistance to decomposition at the temperature of heating.
• a process of rendering textiles repellent to water which comprises 'steeping the same in an emulsion of an anhydride of a high molecular fatty acid in a solution of a stable soap, drying, and heating for 15 to 60 'minutes to a temperature of substantially 70 to degrees C., the said soap being characterized in stability by its resistance to decomposition at the temperature oi heating.
• a process of rendering cotton textile goods repellent to water said goods being unbleached and not having been kler-boiled, which com,- prises' steeping the same in an emulsion containing an anhydride of a high molecular fatty acid. and an alkali metal soap, and exposing for 15 to 30 minutes to a temperature of about degrees C., the said soap being characterized in stability by its resistance to decomposition at the temperature of heating.
