Applicatibmflled Iunc21, 1824. serial No. 721,520.
An important feature of thepresent invention resides in the fact that the moth proofing composition of the present invention is slightly acid in reaction and exhibits no deleterious properties toward the animal fibers. At the same time, it retains the desirable moth proofing properties and may be prepared in such form that it can be readily used alike by the textile trade and housewives with the same efficient and effective results in protecting woolen goods from the ravages of the moth larvae.
Our research and experiments have dempractically neutral or only very! onstrated that a moth proofing composition containing soluble fluorides or soluble silico fluorides or mixtures of these soluble fluorides and silico fluorides can be prepared in such strength in aqueous solution as to impart to the resulting composition properties well adapted 'to carry out the objects of the invention which have been enumerated.
It has been found that certain organic compounds applied alone or in a mixture with one another, or with fluorides or' with silico fluorides, or both, show valuable moth proofing properties. Among these organic compounds are the alkali 'metal salts of henzene sulphonic acids, or of derivatives of benzene sulphonic acid; for example: sodium benzene sulphonate, sodium chlor-benzene sulphonate or sodium benzene di-sulphonate the function of any one of these salts being to enhance the moth proofing effect of the composition.
Another organic compound which may be employed is .a salt of naphthalene beta-sulphonic acid or of its derivatives, as for example: sodium, potassium, lithium or barium salt of chlor-naphthalene-beta-sulphonic acid, or of chlor-naphthalene-beta-di-sulphonic acid; the function of such salt being to materially enhance the moth proofing effect of the composition to which it is added.
In our compositions we may use a soluble sulphate, i. e., sodium sulphate or alum, which we have found assists materially in the Wetting of the fabrics and increases the permanency of the moth proofing effect.
A moth proofing composition comprising the ingredients enumerated produces very satisfactory results when applied to woolen goods for the purpose of moth proofing the same in that the goods so treated are found to be immune to the attacks of the moth larvae and do not show any deteriorationor weakening of tensile strength or durabihty of the fibers or fabrics subsequent to this treatment with such a composition.
It has been found in practice that the ingredients entering into our compositron can be used within the following definite ranges: sodium fluoride, .1 to 2.5%; sodium silico fluoride, :1 to .6%; sodium sulphate, .1 to 1%; sodium benzene sulplionate, .01 to .5%; sodium salt of naphthalene beta-sulphonic acid, .01 to 170; and alum, up to .5 o.
a is of course to be understood that neither all the maximum quantites nor all the minimum quantites given in this formula should be compounded, but we have set forth the practical limits of the respective constitutents which enter into the composition. 0
We usually prefer to employ the ingredients enumerated with the omission of alum when sodium fluoride is used, whereas if the sodium fluoride is omitted, the alum is generally employed.
It is important from a practical standpoint that woolens treated with our composition do not require washing or rinsing as in the case of prior processes where fluorides are applied in strongl acidic solutions.
By the term solub e fluoride we mean to include the fluorides of the alkali metals, sodium, potassium, and lithium, and the metals zinc and aluminum.
By the term soluble silico fluoride we mean to include the silico fluorides of the alkali metals, sodium, potassium, lithium,
and the metals zinc and aluminum.
The term alkali metal salt of benzene sulphonic acid is intended to include also such salts of derivatives of such acid.
The term a metal salt of naphthalene beta-sulphonic acid is intended to include the sodium, potassium, lithium, and barium salt of the substituted and unsubstituted acid.
The term a soluble sulphate is intended to include the alkali metal sulphates as well as zinc and aluminum sulphates, and potash alum.
It is of commercial practical importance that the moth proofing composition which we have hcreinbefore described will not appreciably act on glass and this renders it possible to package the composition for household use in bottles in which it may be kept indefinitely and ready for use.
Having thus fully described the invention, what we claim as new and desire to secure by Letters Patent is:
1. A substantially neutral moth proofing ronilposition containing a soluble silico flu- Ol'lC Q.
