This invention relates to thetreatment of fabrics composed in part on in whole of thermoplastic or organic derivatives of cellulose.
In the ironing of fabrics composed at least,
in part of organic derivatives of cellulose, for instance, cellulose acetate silk, care must be taken to avoid too high temperatures, since if the iron or calender is above 220 C. sticking of-the fabric to the iron or calender and melting of the cellulose derivative will result. While this property of such fabrics causes no more difiiculty than is encountered in the ironing of natural silk, it is desirable to raise the permissible temperature of ironing as much as possible. More over, when fabrics constituted as above, and particularly delustered fabrics of this nature, are ironed while they are damp with ironing means that are above 100 C., the lustre of the fabric is increased. As this increase of lustre is not uniform, an irregular sheen or even'spots are produced.
An object of this invention is to treat fabric composed in whole or in part of thermoplastic or organic derivatives of cellulose so,
as to decrease its tendency to stick to a hot v iron or calender, whereby the temperature of the ironing means may be raised without danger of damage. I
Another object ofthis invention 1s to treat fabric constituted as above set forth, so that it may be ironed while damp with an iron at a temperature above 100 C. without caus-' mg any increase of lustre or spots.
' Another object of this invention is to treat fabiric composed in whole or' in part of thermoplastic or organic derivatives .of cellulose with a bath containing a metallic salt such as basic aluminum acetate whereby its resistance against sticking to a hot iron is enhanced.
Other objects of this invention will appear from the following detailed description. I
In carrying out our invention, the fabric A CORPORATION on DELA- F PRODUCING TEE Application filed October 21, 1927. Serial No. 227,856.'

composed in whole or in part of.thermoplastic derivatives of 'cellulose or organic derivatives of cellulose is treated. The or ganic derivatives of cellulose may be organic esters of cellulose or organic ethers of cellulose. Examples of organic esters of cellulose are cellulose formate, cellulose acetate, cellulose propionate', and cellulose bu-tyrate. Examples of organic ethers of cellulose are methyl cellulose, ethyl celluloseand benzyl cellulose. The fabric may be composed entirely ofone of the above mentioned materials or it may be composed entirely of a .mixture of two or more of the above named materials. Furthermore, the fabric may be a mixed fabric composed of a mixture of yarns made from anyv of the thermoplastic or organic derivatives of cellulose and of yarns made of other fibres. Examples of such mixed fabrics are mixed cellulose acetate and natural silk, mixed cellulose acetate and wool, mixed cellulose acetate and cotton, etc. brevity, a detailed description will be given with respect to a fabric composed entirely In the interest ofof cellulose acetate. However, it is" to be understood that this invention is not lim'-.
other organic acids such as'formic acid, may
- beused.
In one mode of carrying out our inven tron, the celluloseacetate fabric 1s immersed in an aqueous bath containing from 10 grams. to 50 grams of basic aluminum acetate, Al(CH GOO) OH,
fper litre of solution and also containing r om 50 cc. to 100 cc. of acetic acid per litre of solution. The temperature of the bath may be anywhere between ordinary room tem erature (15 C.) to 60 0., although I have ound that a bath temperature of 40 is the best. The time of treatment also may be varied within-large limits, but we have found that no substantial advantages accrue by prolonging the immersion over a period longer than 45 minutes. Asfar as we are aware, the best results. are obtained by immersing the cellulose acetate fabricin an aqueous solution containing 10 grams of basic aluminum acetate per litre and 100 acetic acid per litre maintained at a temperature of 40 0.,
for a period of 45 minutes. The fabric is then, rinsed and dried, and is now ready forany finishing operation that is desired or necessary." I
However, it is to be understood that the conditions of treatment may be varied within wide limits. We have used as a treating bath for the fabric, solutions containing 100 cc. of acetic acid per litre and containing 10 grams, 20-grams, 30 grams, 40 grams and 50 grams of basic aluminum acetate per litre. We have also used as a treating bath a solution containing 30 grams of basic alumiuum acetate and containing 50 cc., 100cc., 150 -'cc.', 200 cc. and 250 cc. of
acetic acid per-litre of solution. We have also used a solution containing 36 grams of basic-aluminum acetate per litre and 50 grams of ammonium .sul'phocyanide per I I litre.
This treatment of cellulose acetate fabric results in a remarkable enhancement of its properties. Thus, cellulose acetate fabric before treatmentby our process will melt and stick to'an iron when such iron is at a temperature above 220 (1, say 225 C. After it has been subjected to thetreatment described above, it may be iron with an iron or calender maintained at a temperature of 230 C. or 240 C. or as high as 250 0. without sticln'ng to the ironing means. The fabric after this treatment may be ironed while in a damp condition with a hot iron maintained above 100C. but below the sticking point, without any increase of lustre,
whereas the lustre of untreated fabric will be increased when ironed in this manner. Furthermore, the treatment with the bath.
- ofbasic aluminum acetate, as set forth above, acts as a water-proofing agent and imparts water-proof properties to the fab-- ric. Part of the basic aluminum acetate of the bath is incorporated-in the fabric either as basic aluminum acetate or as aluminum oxide as is indicated by the fact that the fabric treated in accordance with our invention has an ash content of anywhere from num salt.
0.12% to 1.23% and sometimes more. By variations in the proportions of the ingredients, we have obtained fabrics that do not stick to an iron heated to 280 (3., 240 0., 250 C. or over.
The fabric treated in accordance with our invention has a pearly luster. Furthermore, such fabric is waterproof, as is indicated by the fact that when water was poured into a recess made of this fabric and was permitted to remain overnight, no water had percolated through by the following morning.
It is to be understood that the above detailed description is given merely by Way of illustration and that many variations may be made without departing from the spirit of this invention. 1

1. Method of treating fabric containing thermoplastic cellulose compounds, comprising treating the same with a solution contives of cellulose comprising treating the same with a solution containing an alumi- 5.
