FERDINAND M'U'NZ, OF FECHENHEIM-ON-THE-MAIN, GERMANY, ASSIGNOR TO LEOPOLD CASSELLA 00. GESELLSCHAFT MIT IBESCHRQNKTER HAFTUNG, A CORPORATION OF GERMANY.
PROCESS FOR THE PRODUCTION OF EFFECT THREADS WITH ANIMAL FIBERS.
No Drawing. Application filed April 9,
To all whom it may concern:
Be it known that I, FERDINAND Miin'z, a citizen of the Austrian Republic, residing at Fechenheim-on-the-Main, Germany, have 5 invented a certain new and useful Process for the Production of Effect Threads with Animal Fibers, of which the following is a full description.
Of the materials diminishing the affinity 1: of animal fibers for acid dyestuffs, tannic acid up to now has been of some practical importance, by exerting on these fibers-in combination with salts of metals, stannous salts in particulara reserving effect sufii- 1;: cient to enable the production of multi-coloured effects in piece-dyed goods.
To a more extensive application of this resist method the way hitherto was barred, principally by reason of the effects obtained :0 in this manner, showing a poor resistance to the manipulations necessary in the manufacture of woollen goods, in particular such as washing, milling and prolonged boiling.
It has now been observed that considerably purer and finer effects, offering a by far better resistance to the respective manipulations, washing and milling particularly may be obtained if esterified products of tannic acid instead of tannic acid proper so are employed, the former likewise to be used to good advantage in combination with metal salts.
By completely esterifying the hydroxyl groups of tannic acid products result which owing to their insolubility in Water, may be applied with difficulty only for the present purpose. For this reason the employment of such products mainly is recommended as are formed by a partial esterification only of the hydroxyl groups of tannic acid. These are still soluble enough in water to allow of an easy treatment of the animal fiber in a dilute bath. By using quantities of esterifying agents, insuflicient for ensur- 1923. Serial No. 630,969.
ing complete esterificatio-n, or also by esterifying under milder conditions, such products may easily be obtained.
As esterifying agents anhydrides or chlorides of acids and also the free acids, with or without catalyzer's, come into consideration.
For aftertreating, all metal salts exerting a fixing effect on tannic acid may be employed.
E sample.
100 parts by Weight of tannic acid are sharply dried and dissolved in 120 parts by weight of glacial acetic acid, parts by weight of acetic anhydride are added to the solution at a temperature of 90-100 C. (195210 F.) and this temperature is maintained for 1 hour. A slight quantity of water is then added and the solution allowed to cool.
White or previously dyed wool or silk is treated for 1 hour with 30% its weight of this mixture (reckoned on the weight of the tannic acid employed) in a dilute bath. rinsed and aftertreated for hour at about 90 C. (195 F.) with 5% stannous chloride and 10% acetic acid 30%. The fiber reserved in this manner may be used for white or coloured eilects in fabrics.
Claim.
A process for the production of effect. threads with animal fibers by treating the fiber with esterified tannic acid incombination with metal salts, exerting a fixing effeet on tannic acid.
In witness whereof I have hereunto signed my name this 17th day of March,
