Definitions
- the present invention relates to an improved process for the treatment of natural and synthetic textile fibers, either as such or in the form of yarns, woven and knitted fabrics or articles produced therefrom, with aqueous baths containing peroxidic compounds and more particularly with such baths containing a novel activating agent.
- peroxidic compounds such as hydrogen peroxide, sodium peroxide, sodium perborate, sodium percarbonate, sodium perphosphate and the like, can be used in washing and bleaching baths for textile fibers of all types.
- peroxidic compounds such as hydrogen peroxide, sodium peroxide, sodium perborate, sodium percarbonate, sodium perphosphate and the like.
- temperatures almost up to boiling are used for such washing or bleaching.
- Such high temperatures for the washing and bleaching baths require considerable heat energy and furthermore are not suited for the ordinary washing machine.
- activators which will permit the washing and bleaching operations to be carried out at lower temperatures while still achieving the desired whitening effect and good spot removal.
- activators for example, are: formamide, amides of unsaturated lower carboxylic acids, organic nitriles, anhydrides of diand polybasic carboxylic acids, as well as anhydrides of unsaturated carboxylic acids.
- pyrophosphoric acid esters of fatty alcohols produce complex compounds with hydrogen peroxide which also can be used as components of bleaching and washing agents.
- Such complex compounds possess especially high stability and release the active oxygen at room temperatures much more slowly than, for example, sodium perborate.
- they also act as stabilizers for sodium peroxide, sodium perborate and other inorganic per salts.
- acylated esters for example, have the following wherein R, for example, can be the allcyl groups, such as ethyl, derived from the phosphoric acid ester and the acetylated alkyl is the acyl group, such as an acetyl group, derived from the acylating agent.
- R for example, can be the allcyl groups, such as ethyl, derived from the phosphoric acid ester and the acetylated alkyl is the acyl group, such as an acetyl group, derived from the acylating agent.
- the acylated esters are produced by known methods and exhibit a very good activating action, sufiicient stability and a pleasant odor.
- the bleaching and washing baths according to the invention which contain peroxidic textile bleaching agents and the activators according to the invention can in addition contain known stabilizers, buffering agents, wetting agents, detergents, protective agents for fibers and optical brighteners.
- the best action according to the invention is obtained in neutral, weakly acidic and Weakly alkaline baths or, in other words, at a pH between about 3 and 11.
- the temperature of the baths preferably is between 60 and C.
- the active oxygen content of such baths preferably is between 0.05 g. and 20 g. per liter.
- :It is important for the action of the activators that they are dissolved directly together with the per compounds or shortly before or after such per compounds in order that coaction is ensured.
- Example 7 A rayon stable fiber woven fabric was boiled in red wine and its white content measured and found to be 31%. The measurement of such white content was with the Zeiss-Elrepho-whiteness degree measurer against white standard 565 and with filter 6. I
