Patented Jan. E8, 1938 Grover C. Hoflman, New York, N. 32., assignor of one-half to Helene de Bourgogne, New York,

No Drawing. Application September 28, 1935,

Serial No. 42,573

This invention relates to tissue paper which has been treated in such manner that it is capable of use in the form of bed sheets, pillow cases and other sheet material articles heretofore made of textile material.

In seeking to provide in paper sheet material the desired characteristics of increased strength, suppleness, surface softness, elasticity, noncrackling, permeability and moisture absorption I have in a course of experimentation discovered a treatment for a suitable tissue paper base which enables this material to fulfill these stated requirements.

While the tissue paper to be subjected to my improved treatment may be composed ofany of the paper pulps usually employed in the manufacture of tissue paper I incline to the use of pulp made from white spruce for the reason that its long and strong flexible fibre rendefs this material very desirable; also because the extensive available supply of white spruce assures the relatively low purchase'price of tissue paper made from this pulp.

In carrying out my invention I take tissue pa- 5 per, made as stated from white spruce pulp, or

from any other suitable paper pulp, and subject this tissue paper to treatment by a solution that is capable of importing into the tissue paper the characteristic features hereinbefore set forth.

The solution which has been employed by me is composed of the following ingredients in approximately the proportions set forth, to wit:

Parts by volume Glycerine 1 Ethyl alcohoL -2 Water 3 The glycerine is dissolved in the alcohol and the water added thereto.

A small quantity of talcum powder is added to the solution in the proportion, for example, of about 5% ounces talcum powder to 6 gallons of the solution.

This composite solution is applied to the tissue paper either by immersing the tissue paper in a bath of the solution. 'or otherwise. For example, the'paper'may be run through a bath of the solution while feeding from one roll to another, an idle roll in the bath serving to guide the paper through the bath contents.

From the receiving roll the treated or saturated paper may pass. to a wringer, and suitable drying means may be employed as is obvious.

55 As it is necessary that the talcum powder be in a state of suspension in the solution while the treatment is being performed, suitable means are provided for agitating the solution to prevent precipitation, in order that an even and proportionate distribution of the talcum powder may occur during the treatment.

Tissue paper treated with the foregoing solution will be found to possess-the qualities set forth.

The alcohol is employed as a solvent for the glycerine and to function in drying the treated paper. The .glycerine imparts increased strength, elasticity, suppleness and non-crackling characteristics to the treated paper, and the talcum powder gives to the treated paper a soft and velvety surface.

It is to be understood that while I have pre scribed herein a definite formula as composing the solution for the treatment of tissue paper to give it the qualities named, I do not wish to be limited to the specific ingredients referred to, realizing that my improved art contemplates the use of other ingredients which may constitute the equivalents of those indicated or any of them.

While I have referred to tissue paper in the specification and claims as the paper material to be treated in the manner hereinbefore described I do not intend thereby to limit myself to the use of thepaper material known in the trade as tissue paper, because other paper materials having substantially the same characteristics as tissue paper, and capable of responding to my treatment in approximatelythe same manner as tissue paper may also be employed.

Variations within the spirit and scope of my invention are equally comprehended by the foregoing description.

I claim:

1. The process of treating tissue paper which consists in sgturating the paper with a solution of glycerine, alcohol and water, with talcum powder in suspension therein, then subjecting the paper to a squeezing action and finally drying it.

2. The process of treating tissue paper which consists in saturating the paper with a solution comprising two parts of ethyl alcohol, one part of glycerine with three partsof water, and containing five and one-half ounces of talcum powder in suspension in six gallons of the solution, then passing the treated paper between wringer rolls, while saturated, and finally drying it.
