Patented Oct. 4, 1938 2,131,777 UNITED STATES PATENT OFFICE 2,131,777 METHOD OF PRODUCING OILCLOTH Roderick H. Willcox, deceased, late of Columbus, Ohio, by Bertha P. Willcox and Richard V. Willcox, co-executors, Columbus, Ohio Application August 24, 1937, Serial No. 160,658 2 Claims. (Cl. Ell-67.9) This invention relates to an oilcloth product and method of producing the same. It has to do, more speci?cally, with an oilcloth which is par ticularly useful as a table cover and which has the back thereof printed with a solid or all-over color so as to simulate a dyed effect and present a pleasing appearance. In the making of oilcloth, the back of the fabric is usually left uncoated and uncolored. Conse quently, the back is not very pleasing to the eye, since it appears to be gray or a soiled white. The back of oilcloth in the past has been left uncolored because, heretofore, a satisfactory and economical method has not been devised for col 15 oring the back of the oilcloth. It has been proposed in the past to coat both sides of the oilcloth with 'a heavy coating of oil paint applied in the usual manner so as to pro duce a smooth ?nished oil paint coating on both 20 sides. When both sides of the cloth are coated in this manner, the product becomes too stiff and willpreadily crack. Also, if it is used as a table cover, the under side will tend to stick to the table since the cloth texture surface usually pro vided on the back of the oilcloth has been elim inated. Furthermore, coating both sides of the cloth in this manner would render the cost of the oilcloth prohibitive for the ordinary purposes for which it is used. As previously stated, the back of the oilcloth is usually left uncolored or in the condition which results during the manufacture of the oilcloth. It has been customary, however, in making arti ?cial leather, to dye the cloth which is to be coated in order that the back of the leather will be colored or dyed. In making the arti?cial leather, the original cotton fabric used for the backing is usually put in vats and dyed. The '40 fabric must then be taken out and wrung to squeeze out the excess liquid dye. Then, it must be washed or rinsed a number of times. It must then be stretched to bring it back to its original size. Thus, a number of time-consuming opera tions are necessary in order that the back of the 45 arti?cial leather might be colored and present a more pleasing appearance. These operations make the resulting product quite expensive and, therefore, this method is not feasible in the mak ing of oilcloth, inasmuch as it would make the 50 cost of the oilcloth prohibitive. One of the objects of this invention is to pro vide an oilcloth product which is particularly useful as a table cover and‘ which has the back thereof printed with a solid or all-over color so as to simulate a dyed effect and which blends or harmonizes with the front coated surface of the cloth, thereby presenting a very pleasing appear ance. - Another object of this invention is to provide an oilcloth product having the back thereof printed as indicated to simulate a dyed effect but having the cloth texture and cloth appearance on the back surface preserved. Another object of this invention is to provide a method of making oilcloth wherein the back of 10 the oilcloth may be printed with a solid all-over color in a very efficient and inexpensive manner. Another object of this invention is to provide an oilcloth of the type indicated having the back thereof treated not only to make it more pleasing 15 in appearance but also to make it water-repel lent. In its preferred form, this invention contem plates the provision of an oilcloth product which has the back thereof colored to simulate a dyed effect. This oilcloth product is made by printing 20 a solid or all-over color on the back thereof in _ such a manner that dyed effect is produced. The printing is preferably accomplished by means of a printing roll which has a plurality of ?ne lines or depressions in the surface thereof so that, when Ni 5 it rotates in a bath of the coloring liquid, it will, _ due to capillary attraction, take up some of the coloring liquid and retain it until the roll con tacts with the cloth to be printed. The coloring liquid retained in the small depressions will be a: absorbed by the cloth when it contacts with the roll. Since the entire surface of the roll is pro vided with these closely~spaced minute depres sions, a solid or all~over color will be printed on the cloth. The color printed on the back of the cloth preferably blends or harmonizes with the color of the front surface of the cloth which is provided with a smooth oil paint coating produced in the usual way. The coloring liquid used for printing the back of the cloth is of such a nature that when it is absorbed by the strands of cloth- it will make the back of the cloth water-repellent. In applying this liquid, it is preferably of such a consistency that it will be absorbed readily by the strands of the cloth but will not ?ll the interstices thereof in order that the cloth-like appearance and cloth texture of the back of the fabric will be preserved. This will prevent the back surface of the cloth 4 from sticking to surfaces with which it contacts and will result in other advantages. Thus, the back surface of the oilcloth product will still have the comparatively rough'cloth texture and cloth appearance which is common to the ordinary oil 2,181,777 2 cloth. However, the back surface will be so print ed that it will simulate a dyed effect, and will be uniform throughout. Since it appears to be dyed cloth, the appearance of the back of the oilcloth pressions are illustrated in enlarged detail in Figures 3 and 4. However, they need not, neces sarily, be of the same shape illustrated in Figure 3 although this shape is preferred. Due to capil lary attraction caused by the innumerable de product is greatly enhanced. Furthermore, print ing the back surface in the manner indicatedv pressions I3 in the printing surface of the print ing roller, when the printing roller rotates in ‘the makes the back water-repellent. This application is a continuation, in part, of bath of coloring liquid, all the depressions will the application of Roderick H. Willcox, Serial 10 No. 37,202, filed August 21, 1935. In the accompanying drawing, there is illus trated, more or less diagrammatically, the meth 0d and apparatus which is preferably employed in making the product and the finished product 15 is also illustrated. In the drawing: Figure 1 is a diagrammatic view illustrating a roll of oilcloth with the back surface thereof be ing printed according to this invention. 20 Figure 2 is a view of the printing roll which is preferably used‘in printing the back of the oil cloth. Figure 3 is a microscopic view of a portion of the printing surface of the printing roll. 25 Figure 4 is a section taken substantially on line 4-4 of Figure 3. Figure 5 is a perspective view showing a roll of oilcloth with the back of the cloth printed ac cording to this invention. 80. With reference to the drawing, in Figure 5 is illustrated a roll of oilcloth made in accordance with this invention. It is to be understood that this ?gure is merely a diagrammatic illustration of the cloth inasmuch as it is practically im 35 possible to illustrate in the drawing the exact appearance of the cloth. This oilcloth product has the front surface I thereof coated in the usual manner with a coating of heavy oil paint to provide a smooth ?nished coated surface. A part of this coating when applied'passes through the natural interstices in the fabric and is ex posed on the opposite side thereof. The back 2 of the cloth, however, is not left in the unsightly condition which results during the manufacture of the oilcloth, as was done in the prior art, but is printed with a solid all-over color uniform throughout which is applied to the exposed sur faces of the oil paint forming the oilcloth mate rial projecting through the openings in the fabric 50 and to the exposed surface of the fabric adjacent said openings; and preferably blends or har monizes with the front coated surface I of the cloth. The back surface is printed or colored in such a manner as to simulate a dyed effect, the 55 cloth texture and cloth appearance being pre served. become ?lled with such liquid and, consequently, the printing roller picks up a considerable amount of such liquid, as illustrated in Figure 4. In making this roll, a copper roll having a smooth surface is preferably employed. This roll is covered with a photogravure film and is then etched in order that the small depressions l3 will 15 be formed therein. However, the small depres sions may be formed by machining or in other ways. After the minute depressions are pro duced in the surface of the copper roll, it is preferably plated with chromium or other suit 20 able metal in order to produce a harder and more lasting surface. As previously indicated, the coloring liquid which is used in printing the back of the cloth is of such a nature that it will render the back 25 surface of the cloth water-repellent. This liquid preferably comprises a liquid carrier which is immiscible with water and a suitable pigment. As the carrier, any oxidizing or drying oil may be employed. For example, oxidized sardine oil 30 may be used. Synthetic resins or lacquers also may be employed. Any of the various pigments may be used, depending upon the color desired. In preparing this printing liquid, the pigment is mixed in the oil and the mixture is ground in a 35 colloid mill. Then, enough naphtha or other solvent is added to bring it down to water con sistency. In printing the back of the cloth, the cloth is passed between the rollers 5 and 6, as indicated 40 in Figure 1. The roller 5 rotates in the bath [0 of the printing or coloring liquid. The printing roller picks up the coloring liquid and the doctor blade I l wipes off the excess liquid from the sur face of the roll, leaving only the coloring liquid 45 that has been drawn into the minute depressions on the roll. The pressure drum or roll 6 presses the cloth 3 ?rmly against the surface of the printing roller. The coloring or printing liquid which remains in the fine depressions in the 50 printing roll is taken up or absorbed by the cloth. The coloring liquid is evenly distributed through out the entire back surface of the cloth so as to give it the apearance of having been dyed. Since the coloring liquid used is substantially of water 55 consistency, the ?bers or strains of the cloth will readily absorb it. However, the interstices in the Figures 1 to 4, inclusive, illustrate the method cloth will not be filled and consequently, the cloth and. apparatus which is preferably employed in appearance and cloth texture at the back of the printing the back side of the cloth. Figure 1 60 oilcloth will be preserved. shows a roll of oilcloth 3 which is fed around a In manufacturing the oilcloth, it is preferable number of rollers 4 and then between a printing to ?rst coat the cloth backing with one or several roller 5 and a pressure roller 6. It then passes coatings of ?ller material in the usual way. over other rollers ‘I and 8 into a drying oven 9. , drying, the back side of the cloth is pref The roller 6 is preferably of considerable weight After erably printed in the manner discribed above. 65 and is permitted to press the cloth 3 firmly 65 After it is so printed, it is passed through the against the surface of the printing roller 5. The oven 9 where the solvent used in the coloring printing roller 5 rotates in a bath III of coloring liquid will be evaporated and, consequently, the liquid and a doctor blade H is provided for scraping off excess coloring material from the back surface of thecloth will be dried. Then, the front surface of the cloth which has been 70 70 surface of the printing roll. with the filler coating is coated with one The printing surface of the printing roller 5 is coated or more coatings of heavy oil paint to produce the illustrated best in Figures 2, 3 and 4.‘ The printing surface I! of the printing roller is so smooth finished front surface. In this manner, made that a plurality of closely-spaced minute the ?nished coating is not applied to the surface of the cloth until after the back of the cloth has 75 75 depressions l3 are formed therein. These de 2,131,777 been printed to simulate a dyed effect. Thus, there will be no danger of the ?nished surface of the oilcloth being smeared or otherwise in jured during the printing of the back of the cloth. It will be apparent from the description above that the oilcloth product of this invention is dif ferent from any product heretofore made. This oilcloth has the back thereof printed in such a manner that it simulates a dyed effect but the 10 cloth appearance and cloth texture is preserved. The coloring liquid is applied to the back surface of the cloth in such a manner that a solid or all over color is produced and, consequently, the back of the oilcloth will appear tobe dyed. The color on the back of the oilcloth preferably blends or harmonizes with the color or colors of the ?nished front surface of theoilcloth so that the product is very pleasing in appearance. The coloring liquid not only serves to enhance the appearance 20 of the back of the cloth but is of such a nature i‘ that it will make it water-repellent. The method which is employed for producing this oilcloth product is simple but very eii‘icient and the oil cloth may be produced in an inexpensive manner. 25 This method is much more simple and much more economical than the method previously discussed for producing a colored backing on arti?cial leather and which would make the cost prohibi~ tive. The product produced by this method, 3 Having thus described the invention, What is claimed is: 1. The method of producing an oilcloth or simi lar product which comprises applying to the front surface only of a base cloth of textile material a coating of oil paint to form a ?nished surface, some of which paint passes through the inter— stices of the cloth and appears upon the opposite‘ side thereof, drying such coating, and thereafter ‘ printing the back surface of the cloth with a 10 coloring liquid which is applied both to the coat ing of oil paint which appears through the inter stices of the cloth and to the fabric of the cloth adjacent the same, said liquid being of such con sistency that it will be absorbed by the back of the cloth to form a solid, uniformly applied color so as to simulate a dyed effect which will not destroy the cloth texture and cloth appearance at the back of the oilcloth. 2. The method of producing an oilcloth or simi 20 lar product which comprises applying to the front surface only of a base cloth material of ‘textile fabric a coating of oil paint to form a ?nished surface and which fills the interstices of the cloth and appears upon the reverse side, 25 drying the same, and then printing the back surface ‘of the cloth and the coating material which appears through the interstices thereof 30 however, will be as pleasing in appearance as a on the reverse side with a coloring liquid in such coated cloth product wherein the backing is dyed. By the term “cloth", used in the preceding de scription and the following claims, it is intended cloth texture and which will produce a uniform, to cover fabrics of various kinds. By the term 35 “oilcloth", used in the description and the fol lowing claims, it is intended to cover other simi lar coated fabrics. a. manner as to preserve the cloth appearance and solid all-over color, and thereafter drying the product as thus formed.
