United States Patent 3,379,563 IMPREGNATED DEGRADATION- RESISTANT CLOTH Walter W. Abramitis, Downers Grove, Richard A. Reclr,
Hinsdale, and Charles S. Wilhclmy, Chicago, 111., assignors to Armour and Company, Chicago, [1]., a corporation of Delaware No Drawing. Filed Sept. 8, 1964, Ser. No. 395,008 Claims. (Cl. 117--138.5)
ABSTRACT OF THE DISCLOSURE A soil degradation-resistant cloth is prepared by impregnating the cloth with 0.l5.0% by weight of a preserving agent selected from the group consisting of N-(lmethylalkyl) benzylamines, their double salts and metal complexes, and in which the alkyl group has from 7 to 21 carbon atoms. The preserving agent may be applied in a solvent and then the cloth may be dried.
This invention relates to cloth preservative, and more particularly to a soil degradation-resistant cloth and method of treating the same.
Textile fabrics, such as cotton goods, tentage, bags, etc., which are dependent upon their tensile strength, often lose their usefulness because of contact with the soil. Degradation brought about by contact with the soil results not only from soil fungi but other soil-borne microorganisms and the complex chemical changes that take place in the soil. Because of the complexity of the sources of such degradation, it is good practice to subject cloth impregnated with preservative to soil burial tests, and the tensile strength of cloth after periods of burial is tested to determine the effectiveness of the container, bag, or other cloth product.
An object of the present invention is to provide a soil decomposition-resistant cloth for the above-mentioned uses. A further object is to provide a cloth impregnated with a preservative which is effective fora substantial time against degradation by soil fungi, soil-borne microorganisms, and other degradation agents in the soil. A still further object is to provide a method and means for preserving cloth against degradation in contact with soil. Other specific objects and advantages will appear as the specification proceeds.
In one embodiment of our invention, a textile cloth, such as, for example, a cotton bag, is impregnated with an N-(l-methylalkyl) benzylamine, its double salts or metal complexes, as, for example, soaking the cloth in an acetone solution containing the preservative material, draining off the excess solution, and drying the cloth.
The N-(l-methylalkyl) benzylamine has the following structure N-(l-methylalkyl) benzylamine a where R=721 C atoms The double salt of the N-(l-methylalkyl) benzylamine is prepared by the reaction between the hydrochloride salt of the amine with a heavy metal salt. For example, cupric N-.( l-methalkyl) benzylammonium chloride is so prepared, and it has the following structure:
H CH3 3,379,563 Patented Apr. 23, 1968 "ice t 6H G n- CU. 2C1- I G ur H CH In the above structural formulas, R is a hydrocarbon radical having from 7 to 21 carbon atoms. In the practice of our invention, the concentration range is preferably from 0.1 percent to 5.0 percent.
The impregnating amine material may be applied to the cloth in any suitable manner, as by spraying it upon the cloth, soaking the cloth in the preservative material, etc. For testing the treated cloth, the practice is to bury the cloth for a period of time, say, one or two weeks, and to recover the cloth at the end of the week or two weeks and test it for tensile strength. Tensile strength tests are usually made with a Scott tester, and the percentage of the original cloth strength retained is calculated and recorded. The calculations are as follows:
Average (A-C') X l00 percent strength retamed A=Breaking point of buried treated cloth, pounds pull. B=Breaking point of unburied treated cloths, pounds pull. C=Breaking point of buried untreated cloths, pounds pull.
While we prefer to employ chloride salts, other inorganic salts may be used, such as the acetate, formate, etc. salts. For applying the N-(l-methylalkyl) benzylamines, any suitable organic solvent may be employed, such as, for example, acetone, isopropyl alcohol, ethanol, carbon tetrachloride, ether, etc.
In general, any cellulosic cloth material requiring some tensile strength may be employed, such as cotton, jute, hemp, linen, etc.
Specific illustrative examples of our process and product may be set out as follows:
Example I Specific N-(l-methylalkyl) benzylamines, their double salts and metal complexes were employed for impregnating cotton-toweling strips (l /z x 6"), as set out in the following Table I. The cloth strips were soaked in solutions containing 5.0, 1.0, 0.5 and 0.1 percent of the test chemical, draining off the excess solution. The cloths were dried and were buried, together with untreated control strips, in a rich greenhouse soil held in large trays (2" x 2' x 4'). One-half of the cloths were recovered after one week and the other half at the end of two weeks. The cloths were dried, placed in a Scott tester, and pulled apart until broken. The pounds of pull required were recorded, and the percentage of cloth strength retained was calculated. The results are set out in the following Table I.
