Specification of Letters Patent.
PYBOXYLIN SOLVENT.
No Drawing. Original application filed August 21, 1920, Serial No. 405,053. Divided. and. this application filed February 9, 1921. Serial No. 443,629.
To all whom it may concern:
Be it known that I, ROWLAND B. MITCHELL, a citizen of the United States, residing at Athol, in the county of Worcester and State of Massachusetts, have invented certain Improvements in Pyroxylin Solvents, of which the following description is a specification.
This invention relates to solvents for pyroxylin and is of particular utility in processes of coatingfabrics with pyroxylin compounds, an important example of such processes beingthe manufacture of artificial leather.
I have discovered that by using ethyl propionate as the main solvent, and toluol as the diluent, a mixtureis obtained which has great solvent power in view of the small percentage of solvent, the toluol acting almost or quite as a latent solvent. I have found this combination highly satisfactory in practice and produces good artificial leather when used commercially. Care should be taken to remove the water from all the constituents of the mixtureowing to the well known fact that Water must not be present in pyroxylin solvents.
Other suitable solvents may be used to replace a part of the ethyl propionate if desired.
The following table gives sucha diluted solution, which I have found successful and which is at present cheaper, owing to the fact that ethyl acetate is now cheaper than ethyl propionate, but I prefer the ethyl propionate mixed with the acetate.
Ethyl propionate 20% Ethyl acetate 10% Toluol 501% Ethyl alcohol 20% "lution:
Ethyl propionate 30% Toluol Ethyl alcohol 20% It will readily be appreciated by those skilled in this art that the exact proportions off the ingredients will vary with the reguirements of the product, the nature of he process in which it is used, and the conditions under which the process is practised. It will also be understood that other substances than those particularly mentioned above can be used with ethyl propionate and toluol.
For the purpose of coating fabrics a solution of pyroxylin in this solvent is made,
the percentage of pyroxylin used varying widely with the requirements of the product, and a'coating of this solution then is spread on the fabric after which the solvent is evaporated. The pyroxylin dissolves readily indeed in this solvent, it spreads smoothly, and dries without wrinkles or bloom if given proper treatment and if all water is eliminated from the materials.
A good artificial leather is produced economically with great ease by the use of this solvent.
This application is a division of co-pending application Serial No. 405,053 filed August 21, 1920, and it is limited to the solvent.
in which ethyl acetate is used, the claims common to the two forms of solvents above described being presented in the parent application.
What is claimed as new is:
1. A solvent forpyroxylin consisting essentially of ethyl propionate, toluol, ethyl alcohol and ethyl acetate.
2. A solvent for pyroxylin consisting substantially of eth l propionate 20%, toluol 50%, ethyl alco 01 20% and ethyl acetate 10%.
In testimony whereofI have signed my name to this specification.
RUWJLAND 1e. lurrcnunt.
