PROCESS OF MAKING ARTIFICIAL LEATHER AND PRODUCT 'rnnnmor.
Specification of Letters Patent.
Patented Feb. 28, 1922.
Application filed September 5, 1818. Serial No. 252,685.
- and in the State of Delaware, have invented a certain new and useful Improvement in Processes of Making Artificial Leather and Product Thereof, and do hereby declare that the following is a full, clear, and exact descri tion thereof.
y invention relates particularly to a process of makin artificial leather and the product thereo that is to say, coated fabrics having the appearance of leather.
The object of m invention is to rovide a, process and pro uct thereof, in w ich an artificial leather is obtained that is entirely free from clothy appearance. Hitherto, ar; tificial leathers have had a tendenc to develop a clothy appearance, especial y when submitted to pressure or tension, as for example, when stretched around a corner of an object. It is the object of my invention to avoid the development of such clothy ap pearance.
Further objects of my invention will appear from the detailed description thereof contained hereinafter.
While my invention is capable of embodiment in many different forms, for the purpose of illustration I shall describe only certain forms thereof herein, a preferred form being indicated in the accompanying drawing.
' For example, I may make an artificial leather in accordance with my invention by napping one or both surfaces of a fabric, as
for example the close-mesh woven fabric known as a double-faced moleskin; then applying to a napped surface thereof a nitro-. ce lulose composition, such as the followmg: v
8 parts nitrocellulose by weight, 8 parts castor oil by weight, 84 arts solvent by weight, which a rthe evaporation of the solvent will mat the nap into a mass which will protect and cover up the weave of the fabric; and then applyin to this surface when (1 another coating 0 a nitrocellulose composition which may be the following:
10 parts nitrocellulose by weight, 18 parts castor oil b wei ht, 5 parts pigment by weig t, t 67 parts solvent by weight:
i i Instead of producing the artificial leather in this manner, I may do end upon hiding the weave of the fabric by superimposing thereon a layer of a material which is not woven, and which will, therefore, have no tendenc to show a weave or clothy appearance. uch superim osed fabric may, for example, be a layer 0 felt. In carryin out my invention in this manner, I ma app y to a layer of woven fabric which may e napped and therefore comprise end-attached fibres on one or both sides, or not, as desired, and
which may have an exposed weave or not, as
desired, which fabric, for example, may be moleskin, a layer of a coating composition, such as the 0 lowing:
10 parts nitrocellulose by weight,
18 parts castor oil by weight,
72 parts solvent by weight, upon which I .will immediately apply by pressure a layer of felt before said coating is dry. Upon the surface of the felt I may then apply a layer of nitrocellulose coating composition, as for example the following:
10 parts nitrocellulose y weight,
18 parts castor oil by wei' ht,
5 parts pi ment by weig t,
67 parts so vent b weig t.
An artificial leather made in accordance with any one of the methods above described will be of such a character that not only will the weave or clothinessnot be apparent when located in a given plane, but even when sub. jected to pressure or tension, as for example, when stretched around acorner, the weave or clothiness will not a pear, but will re main entirely hidden. n this way an artificial leather is obtained which will at all times retain its leather-like appearance.
While I have described my invention above in detail, I wish it to be understood that man changes may be made therein without eparting from the spirit thereof.
Claims 1. The process which comprises providing an end-attached fibrous constituent matted with a nitrocellulose coating composition, and then applying a nitrocellulose coating to the upper surface thereof.
3. The process which comprises providing upon the surface of a woven moleskin a protective layer of attached fibrous materials,
and then applying a nitrocellulose coating.
to the upper surface thereof.
4. The process which comprises napping and then matting the nap of a woven moleskin to form a protective layer of solid materials comprising a nap matted with a coating composition, and then applying a nitrocellulose coating to the upper surface thereof.
5. The process which comprises napping and then matting the nap of a woven moleskin to form a protective layer of solid materials comprising a nap matted with a nitrocellulose coating composition, and then applying a nitrocellulose coating to the upper surface thereof.
6. An artificial leather comprising a woven fabric having thereon a protective layer of a nap matted by a nitrocellulose coating composition, and a distinct coating superimposed on the first layer, said second coatin containing a pigment.
An artificial leather comprising a woven moleskin havin thereon a protective layer of an end-attac ed solid associated with a coating composition, and acoating composition layer superim osed thereon.
8. An artific-ia leather comprising a woven moleskin having thereon a protective.
layer of a nap matted by a coating composition, and a separate coating composition layer superimposed thereon.
9. An artificial leather comprising a woven moleskin having thereon a protective layer of a nap matted by a nitrocellulose coating composition, and a separate coating composition layer superimposed thereon.
In testimony that I claim the foregoing I have hereunto set my hand.
