Description

Patented Nov. 20, 1928.
UNITED STATES PATENT orrica TREATING ARTIFICIAL SILK.
No Drawing.
This invention relates to a method of delusterizing and otherwise improving the chara'cter'of textile fibers, threads, films, or fabrics, known as artificial silk, such as are produced from nitrocellulose, cupro-ammonium cellulose, cellulose acet ate, cellulose Xanthate (viscose), cellulose others and similar cellulosic starting materials, and to the resulting products.
Artificial silk products usually have a very high luster and a transparency which gives them an appearance unlike the more pleasing appearance of natural silk.
I have found that the character of artificial silk products may be improved by impregnating the same with an aqueous solution of a salt of titanium, and subsequently decomposing the salt in situ. Thus there is precipi: tated in or commingled throughout the fibers of the artificial silk 2. hydrated oxide or other insoluble compound of titanium which is white and very opaque, giving to the artificial silk a delusterized' appearance, and producing such light absorption eif'ects as are desirable,
As an example, the following is given. 4 grams of a water-soluble salt of titanium, such as for instance, titanium sulphate or an equivalent amount of titanium potassium OX- alate or other suitable salts of titanium, are dissolved in 1000 grams of water. 100 grams of artificial silk are immersed in this solution and allowed to remain there until thorough impregnation iscfiected, and the solution is then heated to a temperature of from about 65 to about 100 C. Or, the artificial silk impregnated with the titanium salt solution is heated injan autoclave to decomposethe titanium salt.
After the decomposition treatment, the artificial silk is washed to remove any soluble matter. and then dried.
The'finished product, instead of having the very high luster of artificial silk, has a pleasing, semi-delusterized appearance. Instead of having the transparent appearance of ordinary artificial silk, itris white, and has an opacity which immediately distinguishes it. This opacity is due to the absorption of light by the precipitated titanium compound. The product, moreover, may be dyed readily. Although the invention has been described by reference to the treatment of artificial silk with a solution of a salt of titanium of a specific strength,- it is to'be understood that Application filed May 13,
1927. Serial No. 191 276.
the inventive concept includes the treatment of artificial silk with a solution of said salt of any suitable strength. In-general', however, the use of fairly dilute solutions is desirable. Furthermore, it is to be understood that the invention does not reside in the use of any specific solvent.
Onlya small amount of deposited insoluble titanium compound is required to give the effects described. Thus for'insta-nce, artificial silk sotreated'that therewill be present.
as low as 0.5% of titanium oxide will be delusterized. r I i I claim:, I I
1. Process ofdelusteriizing artificial silk fibers which comprisesimpregnating the same with a dilute aqueous solution of a titanium salt which is thermally decomposable in the presence of wat'er,and. heating the impregnated fibers in the presence of water whereby there is deposited in, and upon the fibers a water-insoluble titanium compound, the concent-ration of the titanium salt solution used being such as to increase the weight of the so-treated artificial silkfiber's from about4% to about 0.5%. v
2,. Process of delustcrizing artificial silk fibers which comprises impregnating about 100part-s by weight of said fibers with a dilute aqueous solution containing not more salt of titanium which is thermally decomposable in the presence of water, and heating the impregnated fibers to a temperature of from about 65 to about 100 (3., in the pres ence of water.
3. Process of delusterizing artificial silk fibers which comprises impregnating about 100 parts by weight of said fibers with a dilute aqueoussolntion containing not more than about 4 parts by weight of water-soluble than about 4 parts by weight of titanium sulfate, and heating the impregnated fibers to a temperature of from about 65 to about C. in the presence of'water.
4. As a new product, delusterized artificial silk fibers containing a finely divided, Waterinsoluble titanium compound in amount not. greater than about'4% by weight.
5. As a new product, delusterized artificial silk fibers containing a finely divided hydrated oxide of titanium in amount no greater than about 4% by weight.
In testimony whereof, I afiix my signature.
