- and lead preparations for textiles

The invention relates to an agent for washing and bleaching fibers, Yarn, woven, knitted and other textile goods made of natural or synthetic fibers, consisting of aqueous solutions or suspensions and activating agents containing active substances, in particular hydantoin derivatives and urine stabilizers, Wetting agents, pH regulating agents and fiber protection agents, optical brighteners and other substances commonly used in textile treatment from the class of soaps, oils, fats and plastics, which is characterized by an increased shelf life and a long shelf life, especially before it is dissolved or suspended in water Has activating effect.

It is known to use peroxidic compounds, for example hydrogen peroxide, Sodium peroxide, sodium perborate and sodium percarbonate, in V. to use ash and lead liquors for all types of fiber. In However, some fillings have disadvantages when they are used, since high temperatures are used to achieve the desired bleaching effect got to; usually one works at or near the Koohpunktee. Aside from boiling or almost boiling wasoh and bleach baths because of the high expenditure of heat, the disadvantage is that it is not very suitable for washing machines to be.

It has therefore been proposed that the washing and activators Bleaching with fiber and lead liquors containing peroxide compounds Allow eohon at lower temperatures and at the same time deliver a good v / tiß effect and achieve a satisfactory fleok removal permit. Known actuators are z. B. formamide, amides unsaturated lower carboxylic acid »» nitrile, anhydride · tin * and polybasic · * carbon · acids and anhydride · unsaturated carbon «* u ** n. The other eiftd aoylated Phosphoric acid esters have been proposed.

Eb is also known to be diacyl derivatives of hydantoine and substituted ones Hydantoins, for example dimethylhydantoina, as activators for peroxide compounds contained in washing and bleaching baths use. They cause a strong increase in the lightening or lightening effect. Bleaching effect so that the washing and lead temperature, which is 95 to 100 ° C in the usual hot wash, can and can nevertheless achieved the same increase in degree of viability and removal of stains.

However, such aoylated hydantoins, which have more than one aoyl

/ if it is contained in the .molecule, it does not have a sufficient shelf life because it plays split off the corresponding acid in a humid atmosphere. As components of ϊ / ash and bleaching agents are therefore only limited Extensively usable.

The invention was based on the task of being a "means to pocket." and bleaching of fibers, yarns, woven, knitted and other textiles of natural or synthetic fibers, consisting of aqueous solutions containing active ingredient compounds or suspensions and activating agents, in particular hydantoin derivatives as well as usual stabilizers, wetting agents, pH-regulating substances and fiber protection agents, optical brighteners and others in textile treatment Usual substances from the class of the soaps, oils, fats and plastics indicate, which is particularly before the dissolution or Suspension in water is characterized by an increased shelf life and has a high activation effect.

Bas characteristic of the invention is to be seen in the fact that the bleaching and Detergents as activating agents lionoacylderivate of hydantoin and contains substituted hydantoins.

The compounds to be used according to the invention can the TTaeoh »and Bleach baths can be added, but they can also, since they are solid • Lad, as a solo or with indifferent water-soluble Sch «t * coatings, · «B. made of polyvinyl alcohol, which contains active oxygen compounds Washing powders or the preparations therefor are mixed in, after that a ready-to-brew mixture for the preparation of the TTaaeh or bleaching bath • nteht.

The best 'ü'irunnen come in neutral, weakly alkaline, and weak Acid area obtained.

The Ίβηββ of the substances to be used as activators depends on the active oxygen content of the soaking or bleaching bath. Good results are achieved if 0.2 to 2.0 oil activating agent is used for each oil. At tasole solutions with 0.004 mol / l

Sodium perborut 0.002 to 0.008 mol / l activator is recommended. At 0.6 g / l sodium perborate, equivalent to 0.0038% oil / l (cf. Example 1), 0.005 -'ol / l, corresponding to 0.84 g / l, onoacetylhydantoin have been used. Pur bath kit Medium to higher amounts of activator are recommended for lower active oxygen content, whereas lower amounts are sufficient for baths that are richer in active oxygen.
