Description

Patented May 10, 1932 UNITED. STATES PATENT OFFICE HERBERT PLATT, CUMBERLAND, MARYLAND, ASSIGNQR TO CELANESE CORPORA- TIONOF AMERICA, A CORPORATION OF DELAWARE METHOD OF TREATING FABRICS AND PRODUCT THEREOF No Drawing.
This invention relates to the method of treating fabric and relates more particularly to the treatment of fabrics containing organic derivative of cellulose yarn to increase the scroop thereof.
An object of my invention is to increase the scroop of fabrics containing organic derivatives of cellulose by subjecting them to the action of suitable reagents. Other objects of my invention will appear from the following detailed description.
Often it is desirable to increase the scroop of fabrics containing organic derivative of cellulose yarn, and this is particularly true in case of fabrics such as taffeta. I have found that if such fabric is treated with polybasic aliphatic acids and particularly the salts thereof, and part of such acids or salts is permitted to remain in the fabric, an appreciable increase in scroop results.
In accordance with my invention, I improve the scroop of fabric containing yarns of organic derivatives of cellulose by treating the same with polybasic acid compounds, such as I the acids themselves or their salts, and preferably, though not necessarily, in the presence of an emulsion of oily bodies.
A fabric of any construction may be treated in accordance with my invention. Thus the fabric may be either a woven, knitted or netted fabric, but the greatest advantages of my invention accrue when it is applied to fabric, such as taffeta, where high scroop is desired. The fabric may contain yarns of any suitable organic derivatives of cellulose such as orangic esters or cellulose ethers. Examples of organic esters of cellulose are cellulose acetate, cellulose formate, cellulose propionate and cellulose butyrate while examples of cellulose ethers are ethyl cellulose, methyl cellulose and benzyl cellulose. The fabric may consist wholly of such yarns of organic derivatives of cellulose, or it may be a mixed fabric containing such yarns and yarns of other fibres, such as cotton, reconstituted cellulose, natural silk, wool, etc.
The fabric may be treated with a liquid containing in solution or in suspension salts of polybasic aliphatic acids or the acids themselves. Examples of such salts are the tar- Application filed Kay 14, 1929. Serial No. 363,109.
ing and scouring, and after the removal of the excess reagent by wringing or centrifuging, the fabric is dried, without prior washing, in a stretched condition on a frame or tenter. The scroop of the fabric is found to be materially increased.
In order further to illustrate my invention but without being limited thereto, the following specific example is given.
E wample A woven fabric of tafieta construction and consisting wholly of cellulose acetate yarns,
'after'having been scoured, but not calendered, is subjected to any one of the aqueous baths containing the following reagents:
(1) 4 grams sodium tartrate per litre and 6 cc. oliveoil emulsion per litre.
(2) 4 grams calcium oxalate or potassium oxalate per litre and 6 cc. olive oil emulsion per litre.
I (3) 4 grams sodium oxalate per litre and 6 cc. olive oil emulsion per litre.
(4) 4 grams tartaric acid per litre and 6 cc. olive oil emulsion per litre.
(5) 4 grams barium oxalate per litre.
(6) 4 grams sodium tartrate per litre.
(7-) 4 grams sodium oxalate per litre.
' The time of treatment of the fabric in the bath is 15 minutes and the temperature of the bath 45 C. The goods are then removed from the bath, and the excess liquid removed by wringing or centrifugal, extraction, and then, without washing or otherwise removing the liquid still remaining in the fabric, the fabric is dried while stretched on a tenter or frame. The scroop of the fabric is greatly improved, the degree of improvement of scroop being in the order given in the above list of reagents; that is, the fabric treated with sodium tartrate and olive oil emulsion has the highest scroop, while the fabric treated with sodium oxalate alone has the least amount of increase of scroop imparted thereto. I
It is to be understood that the foregoing detailed description is given merely by way of illustration, and that many variations may be made therein Without departing from the spirit of my invention.
Having described my invention, what I claim and desire to secure by Letters Patent is:
1. Method of improving the scroop of a fabric containing yarns of organic derivatives of cellulose comprising treating the fabric with a polybasic aliphatic acid compound.
2. Method of improving the scroop of a fabric containing yarns of cellulose acetate comprising treating the fabric with a poly lulose comprisingtreating the same with a liquid containing asalt of oxalic acid.

7. Method of improving the scroop of a fabric containing organic derivatives of cellulose comprising treating the same with a liquid containing a salt of oxalic acid and in the presence of an olive oil emulsion.
8. Method of improving the scroop of a fabric containing cellulose acetate comprising treating the same with a liquid containing a salt of oxalic acid and in the presence of an olive oil emulsion.
9. Method of improving the scroop of a fabric containing organic derivatives of cellulose comprising treating the same with a liquid containing a salt of oxalic acid and in the presence .of an olive oil emulsion, andthen, without prior washing, drying the fabric.
10. Method of improving the scroop of a fabric containing cellulose acetate comprisin g treating the same with a'liquid containing a salt of oxalic acid and in the presence of an fabric containing organic derivatives of cellulose comprising treating the same with a liquid containing a salt of tartaric acid.
16. Method of improving the scroop of a fabric containing cellulose acetate comprising treating the same with a liquid containing a salt of tartaric acid.
17. Method of improving the scroop of a fabric containing organic derivatives of cellulose comprising treating the same with a liquid containing a salt of tartaric acid and in the presence of an olive oil emulsion.
18. Method of improving the scroop of a fabric containing cellulose acetate comprising treating the same with a liquid containing a salt of tartaric acid and in the presence of an olive oil emulsion.
19. Method of improving the scroop of a .fabric containing organic derivatives of cellulose comprising treating the same with a liquid containing a salt of tartaric acid and in the persence of an olive oil emulsion, and then,
without prior washing, drying the fabric.
20. Method of improving the scroop of a fabric containing cellulose acetate comprising treating the same with a liquid containing a salt of tartaric acid and in the presence of an olive oil emulsion, and then, without prior washing, drying the fabric.
21. A fabric containing organic derivatives of cellulose yarn having an improved scroop and containing a tartrate.
22. A fabric containing cellulose acetate yarn having an improved scroop and containing a tartrate.
In testimony whereof, I have hereunto subscribed my name.
