 dem Kalandern erfolgt. 



     Wiihrend   die bisher bekannten Verfahren, soweit sie überhaupt praktisch ausführbar sind, sich nur mit der Fixierung des sogenannten Seidenfinish befassen, bei tieferen Gaufragen dagegen   sämtlich   versagen, gelingt das vorstehende Verfahren sowohl in den Fällen, wo der zu   fixierende   Effekt mikroskopisch feine, als auch dort, wo er gröüere bezw. tiefere oder ganz grobe oder tiefe   Pressungen darstellt. Alle Effekte werden mit der gleichen Sicherheit fixiert, und die Bügelechtheit der fixierten Effekte ist in allen Fällen ausserordentlich gross.

 the calendering takes place.



     While the previously known methods, insofar as they are practicable at all, deal only with the fixation of the so-called silk finish, but all fail in the case of deeper stitching, the above procedure succeeds both in cases where the effect to be fixed is microscopically fine, as well as there , where he larger respectively. represents deeper or very coarse or deep pressures. All effects are fixed with the same security, and the ironing fastness of the fixed effects is extremely high in all cases.

Claims

Another advantage of the above method is the ease with which it is carried out. If one disregards the impregnation, which means special manipulation, the new process does not take much longer than the usual equipment. The costs for the impregnation bath make up only a small fraction of the amount per meter of goods that has to be spent on other methods that have been customary up to now, for example making the gauzes ironable with nitrocellulose.

Because of its relatively high costs, the nitrocellulose process in particular can only be used with the very best qualities of gurn, while the processing costs of such an expensive process are not profitable for medium and low-quality wool products, which make up the majority of consumption.

PATENT CLAIM: Method for producing iron-resistant or moisture-resistant gauze effects on yarns, fabrics or the like by means of protein substances, characterized in that EMI2.2 calendered with a moderately heated embossing roller that does not cause coagulation and only then exposed to strong dry heat and then steamed with or without pressure, so that the protein or the like coagulates and forms an insoluble coating on both sides of the work material.
