'lhisinvention relates generally to the art of emhroidering, and has more particular reference to a method of preparing pattern material for the embroidery trade capable of being readily disintegrated by the application of heat of such temperature that will not adversely altect the main material to be embroidered.

The invention has for an object the provision of a method of the class mentioned, that is highly eilicient and desirable, and by which pattern material as specified, may be mamiiliactured at a low cost.

The invention has for a further object, the provision of a pattern material of the said type, "which does not disintegrate at normal room conditions as fast as similar material made from. other materials and old methods.

For further comprehension of the inven tion, and ot the objects and advantages thereof, reference will be had to the following description and to the appended claims in which the various novel features of the invention are more particularly set forth.

The method first makes use of glue sized material such as cotton, linen, hemp or pulp fabrics treated with starch or glue. More specifically stated, commercial buckram may be used though the invention is not limited to the sole use of this material. Paper or other fiber products may also be used instead ct buckram, muriatic acid and water are the other elements necessary to carry out the method.

tie that others may make use of my inven tion, I give the following as one of the most approved tormulas for carrying the same out.

Place in any suitable vessel a mixture of (30 gallons oi water, and 4 to 48 pounds of muriatic acid, preferably 12 pounds will be sullicient. The mixture should be at room or lower temperature, approximately from (58 F. to 33 F. and then saturate starched material, preferably buclrram therein. l te move the material and allow it to dry, either naturally or by means 01 a slightly heated conveyor.

Pattern material thus prepared will. keep in good condition for a much longer period ct time, than material prepared by old. methods. A great drawback to the manufacture and sale of pattern material is that after several days the acid within. the material ruins the material and necessitates the dicarding of the ruined material and makes it Application ea January 20, was.

impossible to ship the treated material. to distant embroiderers. This forms a bar to the stocking of the material in the trade.

Material made according to the instant disclosure lasts approximately twenty times as long as material made according to old methods. Obviously this is a great advantags in the embroidery trade.

Pattern material of the class mentioned has several uses in the embroidery trade. One use consists in designing the pattern material, then basting the same to material to be embroidered. Embroidering is next done according to the pattern thru both. materials. Upon completion a hot iron is applied io the materials or the material is placed in a hot room and the pattern mate: rial disintegrates at a temperature of about 170 which temperature does not aii ect the main material, and the charred pattern material may be readily removed.

In material made in accordance with the present invention, the acid resist protects the fabric from the action of the acid tor an extended period of time at normal atmospheric temperatures, as the reaction between the acid and the resist is very slow. Upon application. of heat to the material, however, the acid reaction is greatly accelerated and both the acid resist and fabric are rapidly disintegrated.

li hile I have described my invention with some degree at particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit or the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by United States Letters Patent is:

1. A process for preparing pattern material for embroidery purposes, comprising the step of sizing fabric material with an acid resist, saturating the sized material with diluted muriatic acid, and then drying the acid saturated material.

9;. A. process for preparing pattern material ior embroidery purposes, comprising the step 01": sizing fabric material with starch, saturating the sized material in a diluted acid, and then allowing the acid saturated material to dry in the atmosphere at substantially atmospheric temperatures.

ing, comprising fabric material, sizing thereon, inuriatic acid on said sizing, said acid being slow acting at atmospheric tempera tures, said acid being adapted to rapidly disintegrate the sizing and fabric at a temperature of substantially 170 F.

In testimony whereof I have ailixed my signature.
