  Verfahren zum Schätzen von Pelzen, Federn, Haaren,   fibrösen    Materialien,
Leder und andern Waren vor   Mottenraupenfrass.   



   Es wurde   gefunden, daB Pelze, Federn,    Haare, fibr¯se Materialien, Leder und andere Waren in   hervorragendem      Mae    vor   lVlotten-    fra¯ gesch tzt werden, wenn man sie mit Stoffen behandelt, die dem Formelbild
EMI1.1     
 entsprechen, worin X ein Atom Sauerstoff oder Schwefel bedeutet ; ausserdem können die beiden Kerne je in ortho-Stellung zum   Brückenatom nochmals direkt oder duroh ein    Sauerstoffatom verbunden sein. Durch geeignete   Alkyl-oder Halogensubstitution wird      die Wirksamkeit dieser Mittel besonders ge-    steigert.



   Gegenstand des vorliegenden Patentes ist ein Verfahren, zum Sch tzen von Pelzen, Federn, Haaren, fibrösen Materialien, Leder und andern Waren vor   MottenraupenfraB,    wonach man Verbindungen verwendet, die die Atomgruppierung
EMI1.2     
 enthalten. Besonders wirksame Substituenten sind Alkylgruppen und Halogenatome ; je in   o-Stellung    zum   Brückensauerstoff    kann ein beiden Kernen gemeinsames Sauerstoffatom stehen oder beide Kerne können in diesen Stellungen   dirent    verbunden sein.



   Im folgenden seien einige der in Frage kommenden Verbindungen aufgezählt : x,x-Dichlor-diphenyläther (erhalten durch Chlorierung von Diphenyläther), Diphenylenoyxd, 3-Chlordiphenylenoxyd, 3-Amyl-diphe  nylenoxyd,    3-Chlor-6-methyldiphenylenoxyd,    3-Bro, m-2-methyltdiphenylenoxyd, 3-Chlor-6- amyldiphenylenoxyd, 3, 6t-Dichlordiphenylen-    oxyd, 3, 7-Dichlordiphenylenoxyd, 1-Chlor-6bromdiphenylenoxyd, 3,8-Dichlor-6-methyl   diphenylenoxyd, 2, 3, 6-Trichlordiphenylen-    oxy, d, Diphenylendioxyd usw.



   Die meisten dieser Verbindungen sind im   Sehrifttum bes°hrieben    ; sofern, sie unbekannt sind, lassen sie sich nach üblichen Verfahren darstellen. Die genannten Körper eignen sich hervorragend zum Schützen von Haaren, Pelzwerk,   Federn, fibrösen Materialien, Le-    der, natürlichen oder künstlichen Fasern, Papier oder diese Stoffe enthaltenden   Gegen-    ständen vor Mottenfrass. Bereits in geringen Konzentrationen verleihen sie der behandelten Ware zuverlässigen Schutz. Für die Verwendung kommen hauptsÏchlich L¯sungen in billigen organischen Lösungsmitteln, wie Kohlenwasserstoffen, Chlorkohlenwasserstoffen, Alkoholen, Ketonen usw. oder in deren Gemischen in Frage.

   Die zu schützenden Stoffe können durch Bestreichen,   Bespritzen    oder   Eintauehen,    imprÏgniert werden. Die hier beanspruchten Verbindungen kommen auch in Kombination mit andern, für gleiche   Zwe°ke    schon bekannten   Bekämpfungsmit-    teln in Betracht. So zum Beispiel eignen sich Mischungen mit Sulfoxyden, Sulfonen oder   Thianthrenen.   



   Beispiel :
Man löst 5 Teile   x,    x-Dichlor-diphenyl äther in 995 Teilen   Aoeton,    behandelt Pelze,   Pedern    oder fibr¯se Materialien durch   Tau-    chen, zentrifugiert und trocknet. Das so behandelte Material ist   mottenecht.    Es   ge-    ntgen aber auch schon   Losungen    mit 2 g im Liter, um   einen waschechten    Effekt zu erzielen.   



   I) erS6hutz flirdas vorliegendeVerfahren    wiird nur insoweit beansprucht, als es sich nicht um eine ftr die Textilindustrie in Betracht kommende, nicht rein mechanische Behandlung von Textilfasern handelt.



  



  Methods of estimating fur, feathers, hair, fibrous materials,
Leather and other goods from moth worms.



   It has been found that furs, feathers, hair, fibrous materials, leather and other goods are to an excellent degree protected from lvlottenfrā if they are treated with substances that correspond to the formula
EMI1.1
 correspond to where X is an atom of oxygen or sulfur; In addition, the two nuclei can be connected either directly or through an oxygen atom in the ortho position to the bridge atom. The effectiveness of these agents is particularly increased by suitable alkyl or halogen substitution.



   The subject of the present patent is a method for protecting fur, feathers, hair, fibrous materials, leather and other goods from moth worms, according to which compounds are used which the atomic grouping
EMI1.2
 contain. Particularly effective substituents are alkyl groups and halogen atoms; depending on the o-position to the bridging oxygen, both nuclei can have a common oxygen atom or both nuclei can be directly connected in these positions.



   Some of the compounds in question are listed below: x, x-dichloro-diphenyl ether (obtained by chlorination of diphenyl ether), diphenylene oxide, 3-chlorodiphenylene oxide, 3-amyl-diphenylene oxide, 3-chloro-6-methyldiphenylene oxide, 3-bro , m-2-methyltdiphenylene oxide, 3-chloro-6- amyldiphenylene oxide, 3,6t-dichlorodiphenylene oxide, 3, 7-dichlorodiphenylene oxide, 1-chloro-6bromodiphenylene oxide, 3,8-dichloro-6-methyl diphenylene oxide, 2, 3, 6-trichlorodiphenylenoxy, d, diphenylenedioxide etc.



   Most of these connections are described in scholarship; if they are unknown, they can be represented using standard methods. The bodies mentioned are outstandingly suitable for protecting hair, fur, feathers, fibrous materials, leather, natural or artificial fibers, paper or objects containing these substances from moth damage. Even in low concentrations, they give the treated goods reliable protection. Mainly solutions in cheap organic solvents such as hydrocarbons, chlorinated hydrocarbons, alcohols, ketones, etc. or in mixtures thereof are suitable for use.

   The substances to be protected can be impregnated by brushing, spraying or thawing. The compounds claimed here can also be used in combination with other control agents already known for the same purposes. For example, mixtures with sulfoxides, sulfones or thianthrenes are suitable.



   Example:
5 parts of x, x-dichloro-diphenyl ether are dissolved in 995 parts of aoeton, pelts, pedals or fibrous materials are treated by immersion, centrifuged and dried. The material treated in this way is moth-proof. However, solutions with 2 g per liter are also required in order to achieve a real effect.



   I) Protection of the present process is only claimed insofar as it is not a purely mechanical treatment of textile fibers that is suitable for the textile industry.
