Patented Sept. 16, 1941 UNITED- STATES PATENT OFFICE METHOD OF HHPROVING THE ADHESION OF RUBBER T COTTON Richard A. Crawford, Akron, Ohio, assignor to p The B. F. Goodrich Company, New York, N. Y.,
a corporation of New York No Drawing. Application August 17, 1939, Serial No. 290,625
Claims.
v This invention relates to the adhesion-of rubber to cotton in the form of cords, fabrics, and the like.
The length of service of many articles of commerce embodying cotton and rubber such as tires and belts, for instance, is largely dependent upon the degree of adhesion between the rubber and the cotton. It is the principal object of this invention, accordingly, to provide a method whereby the adhesion between the rubber andthe cotton may be increased.
The method of this invention comprises the application of a shellac-amine soap to cotton prior to associating the cotton with rubber and vulcanizing the composite product. Shellacamine soaps are a well-known class of compounds prepared by the saponification of shellac with amines such as methyl amine, ethyl amine, dimethyl amine, trimethyl amine, triethanol amine, ethylene diamine, triethylene tetramine, cyclohexyl amine, piperidine, morpholine, etc., the soaps prepared from strongly basic amines such as the alkyl amines being preferred.
The shellac-amine soap may be applied directly to the cotton if desired. This method, however,
. may produce unnecessarily thick coatings on the cotton, so it is ordinarily preferred to deposit the soap upon the cotton from solution. The shellacamine soap is usually added in a rather volatile solvent such asalcohol to aid in the drying of the cord, although aqueous solutions may be em ployed if desired. The soap may be applied to the cotton fibers by any desired means, although dipping the cotton in the dispersion is the method now preferred. The cotton is then dried prior to association with unvulcanized rubber.
In case the cotton is in the form of cords, the
treated cords may be dried under tension in the manners well known to the art. 7
As a specific embodiment of this invention,
, square woven cotton fabric was dipped in a 10% alcoholic solution of a soap prepared by the saponiflcation of equivalent amounts of diethyl amine and shellac (7.27 parts by weight of diethyl The treated fabric was dried and coated with a tire carcass stock. Two plies were superposed and vulcanized under pressure in a heated mold together with similar structures made from untreated fabric.
When it was attempted to separate the plies,
it was found that a 35% improvement in adhesion was obtained by treating the fabric with the shellac-amine soap;
, the treatment of this invention, but it has been found by tests on tires containing the treated cords of this invention that the temperatures developed in the tires during operation is greatly reduced. ton cords of this invention accordingly last longer and run with less danger of blowing out than ordinary tires.
Although I have herein disclosed specific examples of the method of my invention, I do not intend that the invention be limited solely thereto, for it will be ,obvious to those. skilled in the art that many modifications are the spirit and scope of the invention as defined in the appended claims.
I claim:
' -1. The method of improving the adhesion of rubber to cotton which comprises applying to the cotton a shellac-amine soap, associating the treated cotton with vulcanizable rubber, andvulcanizing the assemblage.
2. The method of improving the adhesion of rubber to cotton cord which comprises applying to the cord a solution of a shellac-a'nine soap,
drying the cord, associating the treated cord with vulcanizable rubber, and vulcanizing the assemblage.
3-. In a method of adhering rubber to cotton,
.' the step which consists of applying a shellac-.
amine soap to the cotton prior to association with the rubber.
.4. The method of claim 1 in which the shellacamine soap is prepared from shellac and an alkyl amine.
5. An article of manufacture comprising cotton containing a shellac-amine soap and a layerof I vulcanized rubber adhered to the cotton.
