Description

UNIT D STATES PATENT OFFICE.
STANLEY I. LOVELL, OF BBQ CK'ION, MASSACHUSETTS.
COLLOID-TBEATED FABRIC.
1,256,240. 110 Drawing.
State of Massachusetts, have invented new and useful Improvements in Colloid-Treat ed Fabrics, of which the following 1s a specification.
My invention is a new treated fabric in or on which colloidal substances are deposited in a finely comminuted or porous form and retained thereon and therein by engagement of the particles of colloidal substance with the fibers of the fabric and with each other and my invention also includes a method of producing this treated fabric. This new fabric may be of woven material, such for example, as cotton cloth, or of structureless material, such as felt or paper and is impregnated or coated with a colloidal substance, such for example,
as nitro-cellulose, casein, albumen, various gums, resins-or rosm.
This fabric I produce in the following manner: Taking a sheet of the material that it is desired to treat it is treated in a dipping tank, or other suitable receptacle, with the colloidal substance to be used (for example some of the substances mentioned above), the colloidal substance being diffused or dissolved in a suitable medium, such for e2:- ample as alcohol, acetone, ether, ammonia solution, etc. To persons skilled in this art the suitable medium for the particular solid which is to be used will be known or readily ascertainable from published works of authority. The impregnated or coated fabric is then passed to a water bath as rapidly as may be, in which the impregnated or coated fabric remains until displacement of the solvent liquid is practically 'completed by the water, which varies in time according to the nature of the solid employed, the nature of the solvent and the substance or body of the fabric employed. For instance, nitro- "cellulose in acetone on light weightcotton cloth will require perhaps ,the minimum immersion 'to effect the displacement of'one liquid'by the other. It will be unnecessary to elaborate upon the timenecessary for immersion, since the ascertainment of the propertime for. immersion is easy-by simple manipulative tests. Squeezing the treatedfabric, if the dis lacement of solvent is not complete, will bring to the surface particles Specification of Letters Patent.

or drops of colloid solution, easily identified by its elatinous character.
The abric is now withdrawn from the water bath, dried and the solid will be found precipitated in or on the fabric and 1elrlitangf ed and interlocked with the fibers ereo The new material forms the raw material for a number of distinct uses, and as such a raw material is economically superior to other available materials. As a substitute for leather in stiifenin certain parts of a shoe it may be dipped ma suitable solvent and instantaneously the finely comminutedor porous colloidal material is resolved into a coalescent, flaccid body which may be instantly placed and conformed and will dry in the desired shape, stiff, flexible and resilient. As amaterial for imitation linen collars and the like, the blank is treated with suitable colloidal material in the sheet, which is precipitated as described; blanks are died out and each is dipped in solvent and instantaneously the. comminuted or silience will restore it, if distorted.
This instantaneous operation of the sol vent in the use of my new treated fabric is important in many applications, since it prevents the ossibility of destruction of the goods which frequently happens when sqakm of the fabric is necessary to prepare the fa ric for use, as is usual, for if the soaking be continued too long the solid may be partially or entirely removed and the goods damaged or entirely ruined.
Futhermore, the instantaneous solubility of the solid renders unnecessary the coordination of the tempering or preparatory process and the actual working. In older processes where a fabric was tempered or prepared by long continued soaking the workman might get more fabric to the proper temper than he could work up, in which case the surplus was likely to be overtreated and more or less damaged or the workmanmight be obliged to wait for the goods to arrive at the proper temper. The exact coiirdination of the temperlng process rarely attained.

DISCLAIMER 1,256,240.Stanley P. Lovell, Brockton, Mass. COLLOID-TREATED FABRIC. Patent dated February .12 1918. Disclaimer filed March 16, 1934, by the assignee, C'elastic Corporation.
Hereby enters this disclaimer to that part of said specification which is in 'the following words, to wit:
Or paper (page 1, lines 19 20) casein, albumen, various gums, resins or rosin (page 1, lines 21, 22); '.!for examp e, some of the substances mentioned above" (page 1, lines28 and 29); ammonia solution" (page 1, lines 32, 33).
Your petitioner hereby enters disclaimer to the subject matter of the claims of said patent] ,256,-240, except where a cloth fabric is employed whose interstices are filled with precipitated nitrocellulose in such state of subdivision and porosity that the resulting roduct is capable of being made flaccid substantially instantaneously by the use 0 an appropriate solvent, and in that condition is capable of being formed into a desired shape and become stiff, flexible, and resilient in its new form upon vaporization of the solvent.
