'MOTHPROQFED ARTICLE.

No Drawing. v

This invention pertains to articles, more especially articles composed of "wool or other animal fibers, in whole..or 1n part,

articles made therefrom, such as fabrics and piece goods of various kinds, furs. tissue, or other forms of associated or massed fibers. o

The materials specified, having been treat- .ed as hereinafter described, are resistant to the attack of moth larvae without substantial diminution in their tensile strengths or deterioration in any other respect, are substantially neutral in character and normal to the feel, and have adsorbed in the fibers thereof certain compounds of fluorine, aluminum and silicon The presence of these elements is revealed by suitable analytical chemical tests well known to the art.

Typical of a specific moth proofing composition which we may employ in producing the novel articles or products specified is the following:

. Percent. Sodium silico fluoride 0.5 Alum 0.3 Oxalic or citric acid 0.01

It will be noted thatan especially small percentage of the organic acid is employed,

' either dipped into an a ueous solution containing the above ingre ients, preferably in the proportions s ecifiec or the materials may be sprayed with the-solution. Regardless of the specific method of treatment, assuming the solution is properly adsorbed by the fibers, the ultimate articles possess "Application filed July 17, 1925. Serial No. 44,863.

the characteristics enumerated above. It is robable that there may-be an interaction etwecn or among the ingredients, entering into the composition, but, in any event, the chemical qualities enumerated, namely, the presence of fluorine, aluminum and silicon characterizes the treated materials.

The scope of the invention is commensw rate with the appended claims.

Having thus fully described the invention, what we claim as new and desire to secure by Letters Patent is:

1. As a new article of manufacture, animal fibers impregnated with a moth repellent composition resulting from a mixture of compounds of fluorine, silicon and aluminum.

2. As. a new article of manufacture, animal fibers impregnated with a moth repellent composition comprising water soluble. .compounds of fluorine, silicon and alumiwherein the constituent fibrous material wherein the constituent fibers are impregnated with a moth resistant composition containing sodium silico fluoride, alum, and a small quantity ofanmoth 1 proof by a composition containing a water soluble compound of fluorine and 'sllicon and a water soluble salt of aluminum, said fibers being substantially neutral chemically and not deteriorated by the process of moth proofing.

7. Anew'article of manufacture embodying animal fibers which have been rendered moth proof by an impregnation. of their fibers with a-solution containing a Water soluble compound of fluorine and silicon, and EL Water soluble salt of aluminum, said solution being allowed to dry therooq wlthoo lzwal ing o1; {ugzthor treatment.

8. A moth repellent fiber having incorggmyted tghemin. tho produots rosulting from the aqueous interaction of sodium silico fluoride and wator soluble aluminum salts.

In testimony whereof We have signed the 10 foyegoing specification.
