Description
Patented Feb. 25, 1930 UNITED STATES PATENT OFFICE WILHELM LOMMEL, OF WIESDORF-ON-THE-RHINE; HEINRICH MIl'NZEL, OF LEVER- KUSEN-ON-THE-RHINE; AND WINFRID HENTRICH AND MAX HARDTMANN, OF
WIESDORF-ON-THE-RHINE, GERMANY,
ASSIGNORS TO I. G. FARBENINDUSTRIE AKTIENGESELLSCHAFT, 0F FRANKFORT-ON-THE-MAIN, GERMANY PROCESS FOR PROTECTING MATERIALS AGAINST ATTACK BY MOTHS No Drawing. Application filed March 1 1, 1927, Serial No, 174,693, and in Germany March 15, 1926.
The present invention relates to a process for protecting materials against attack by moths and to the materials thus obtained.
In accordance with this invention the protection of Wool, fur, hair and the like from attack by moths is effected by a. treatment of the material in question with the esters of phosphoric acid, so that the same are uniformly incorporated Within the materials and permanently retained therein.
According to our preferred mode of Working the materials to be moth-proofed are immersed in solutions of the phosphoric acid esters in suitable solvents, as for example benzine, L carbon, tetrachloride, alcohols such as for instance ethyl and methyl alcohol, and the like, or they are sprayed with such solutions or treatcclb some such rocess whichwill serve to incorporate the desired mothproofing ingredient, so that it will be retained thereafter. It will be understood that other carriers or diluents may be used.
The following examples will serve to illustrate the principles underlying our invention:
Example 1 The goods are immersed in a 2% solution of diphenyl-o-cresyl-phosphoric acid ester in benzine and after removal of the excess of 0 liquid they are dried. The goodsafter the treatment are moth-proofed Without detriment to the color and other physical characteristics.
' Example 2 A 1% solution of triphenyl phosphoric acid ester in Wood alcohol is sprayed upon the article to be mothproofed. After the evaporation of the alcohol the goods are fully protected against attack by moths.
In an analogous manner other esters of the phosphoric acid, such as the diphenyl-anaphthyl ester, diphenyLB-naphthyl ester, diphenyl-o-,.m-and p-cresyl esters, phenyl- (li-m-cresyl ester, tri-o-chlorophenyl-ester, tri-oand p-chloro-phenyl esters, monophenyl-di-m-chlorocresyl ester, tetraphenylresorcyl ester, tricresyl ester or the like, or
suitable mixtures of any two or more of these, can be applied. Such mixtures can be produced either by mixing the pure esters in any of the esters directly from a mixed starting material such as for example crude cresol.
Other moth protecting agents, e. g., such as are described in our prior Patent No; 1,562,- 510 can also be admixed with the phosphoric acid esters, if desired.
\Ve claim 1. The process for protecting Wool, furs and other materials against attack by moths, which consists in impregnating the material with a solution of a phosphoric acid aryl ester.
2. The process for protecting wool, furs and other materials against attack by moths which consists in impregnating the material with an aryl ester of phosphoric acid.
3. The process for protecting Wool, furs and other materials against attack by moths which consists in. impregnating the material with an alcoholic solution of diphenylcresylphosphoric acid ester.
4. Materials which are liable to attack by moths impregnated with an aryl ester of phosphoric acid.
5. Materials which are liable to attack by moths impregnated With diphenyl-cresyL- our hands. WILHELM LOlVlMEL. HEINRICH MUNZEL. WINFRID HENTRICH. MAX HARDTMANN.
