12 claims. (ci. 154-46) This invention relates to coated fabrics and more particularly to such products adapted to serve as leather substitutes.
This invention has as an object the production of a coated fabric product. A further object is the production of a. leather substitute which is of decorative Aappearance and of general utility in the arts. A still further object is to impart certain desirable properties to fabrics which they do not naturally possess. Other objects will appear hereinafter.
The objects are accomplished by the following preferred mode of procedurey which will be described in connection with the figure in the drawing showing a. section of the preferred form of'our coated fabricl product.
A woven sheeting 1, preferably oneof such a weight to be equivalent to approximately 2.5 yards per pound per 58 in width, is dyed, by the usual method of jig or padder dyeing, a color approxlrnating the color of the finished product, this color being determined by the pigment in the coating composition next applied. This fabric may be a plain weave fabric, .such as for instance, a sheeting, or other types of weaves, as drills, etc. After the material is dyed and carefully dried, it is coated in a suitable machine by means of a doctor knife having a sharp edge with two coats of a pigmented cellulose nitrate-softener composition of the approximate following formula:
Per cent .Cellulose nitrate 26-23 Softener 46-52 Pigment 28-25 `roller embossing equipment in the grain ywhich is desired in the ultimate finished product. Ifv it is desired to produce a two-tone effect in thel finished product, the material after embossing Ois treated with a composition similar to that noted above but usually in a contrasting color in order to give the final two-tone effect. This coated material is then combined by the usual doubling or combining operation to another fabric 4, either a sheeting, drill, Sateen, or heavier fabric, by means of a suitable adhesive, as for instance, rubber cement. -The adhesive is applied to both fabrics and then the fabrics combined by passing thru the doubling machine. The rubber cement may be replaced by other suit- 00 able adhesives, such as pyroxylin compositions, and treated oil compositions, ete.l
A special coating 5 comprised of the following ingredients is now applied to the surface of coating 2. 05
Per cent Cellulose nitrate 10.8 Ceresin wax (refined) 2.7 Dibutyl phthalate 10.8 Ethyl acetate C. P.. l 17.3 Denatured ethyl alcohol 33.6 Toluol C. P 24.8
Dry solids in these compositions vary between 12 and 28%. If desired, however, the composi- 75 tions may be further diluted with such materials as toluol, benzol, or gasoline. These ingredients are preferably compounded in the'following manner: The ceresin wax, after being liquefied by heating, is carefully mixed with warm toluol by thorough agitation. To this solution of the wax is added a cellulose nitrate dispersionjin a solvent consisting of ethyl acetate and denatured alcohol in a concentration of approximatelyl 17%. The mixture is carefully stirred until an even and perfectly smooth dispersion is obtained. The dibutyl phthalate is then added with constant stirring. After the coating 5 of this composition is applied, a special lustrous finish may be obtained by further embossingf The ratio of the ingredients in the above mentioned coating composition from which the coat- .ing 5 is obtained, may vary somewhat from the valuesA indicated. Thus, the cellulose nitrate may vary between 5 and 15%, the ceresin wax from 1 95 to 9.5%, the dibutyl phthalate from to 15%, the ethyl acetate from 16 to 21%, the denatured ethyl alcohol from 28 to 36%, and the toluol from 20 to 35%. These ingredients may also be'substituted by equivalents as will be understood by those'skilled in the art. Suitable wax-like substances that may replace the yceresin wax men'- tionedimthe example are as follows; carnaubal wax, candelilla' Wax, paraffin wax, or similar straight chain hydrocarbon waxes, solid hydrocarbon waxes of the cyclic type, Japan wax, Montan wax, spermaceti wax, hydrogenated cas-r tor oil, and resinsof the polyhydric alcoholpolybasic acid type.
These resins, as understood by those skilled .no
in the art, are the reaction products of polyhydric alcohols (as glycerol) with polybasic acids (as phthalic anhydride) in which drying oils, oil acids, or other modifying and solubilizing agents have been incorporated. Suitable softening agents, other than dibutyl phthalate, may be exemplined by: dibutyl tartrate, tricresyl phosphate. raw castor oil, blown castor oil, and blown cotton seed oil. Various organic solvents may replace those mentioned, as for instance, acetone, butyl acetate, ethyl propionate, methyl alcohol, benzol, and xylene.
While it is desirable to interpose the coating 2 composed of cellulose nitrate. softener and pigment between the nnal or outside coating comprised of the ingredients referred to above, it is to be understood thatl a valuable coated fabric product is obtained by applying the coating 5 directly to the base material 1. The treatment herein disclosed results in the production of a nlm on either coated or uncoated fabric which is discontinuous with respect to the principal ingredient, namely, cellulose nitrate. The exceptional properties which characterize our improved product are due to the existence of this discontinuous type of nlm. Among the properties referred to may be mentioned the extremely high exudation temperatures and low cold crack temperatures. It is preferred, however, to make the product as indicated in the drawing because of fthe leather-like and attractive nnishimparted to the composite product by the coating 2.
, A coated fabric product made in accordance with the present inventio si. e. several valuable characteristics. The product has soil resistance; that is, dust and dirt do not adhere to the surface as in the case of regular fabrics. Oil and grease do not penetrate the surface as is the case with untreated fabrics. The product is also washable in that dust and dirt, as well as oil and 'grease can be satisfactorily removed by the usual cleaning agents without harming the fabric. Since the product is water repellent, the material does not absorb water as untreated fabrics do, and the material, therefore, shows little tendency to shrink. '111e treatment also appreclably reduces the tendency of the fabric to fade.
