Example N 0. 1.-One 1) part of artificial silk made from cellulose acetate is treated 16 with thirty (30) parts of 40 Tw. solution of stannic chloride (SnCh) during one-half hour, at a temperature between 40 and 50 0., then rinsed oil in water, then treated with 7 Tw. solution of di-sodium hydrogen phosphate (Na HPO and rinsed again, and then treated with 7 Tw. solution of sodium silicate, and washed with or without soap solution. The result will be a substantial increase in weight and volume of the i fibers, fabrics and articles.
Example N 0. 2.One (1) part'of cellulose acetate artificial silk is treated with thirty parts of stannic chloride solution of 40 Tw., at a temperature between and 30 55 C., during one-half A hour. Then rinse ofi in water and treat with sodium silicate 7 Tw. and wash with or without soap solution. The result will be a substantial increase in weight and volume of the fibers,

Example No. 3.One 1) part of cellulose acetate artificial silk is treated with thirty (30) parts of 40 Tw. solution of stannic chloride, during one-half hour, at a temperature between 55 and 65 (3., then rinsed ofi in water and treated with 7 Tw. sodium silicate solution, and washed with or without soap solution. The increase in weight and volume is larger in this case than under Example No. 2.
Application filed September 22, 1925. Serial No. 57,956.
Theseexample are only descriptive and not limited and the temperature, as well as the time, can be varied within limits, as well as the strength of the stannic chloride and disodium hydrogen phosphate and sodium silicate solution within limits. In case, for instance, the temperature should be raised, it is advantageous to reduce the time of action of the stannic chloride. Instead of stannic chloride other metal salts, like zinc chloride, can be used, which are swelling agents for the cellulose acetate or for the cellulose ester or cellulose ethers, or other metal salts can also be used which are only slight swelling agents for the particular fiber, when they are used in conjunction with a swelling agent of the particular fiber. This process can be applied to the fiber itself as well as to a fabric made out of this fiber; for instance a fabric made of 100% cellulose acetate silk. The operations described in above examples can be repeated once or several times if it is desired to get a larger increase of volume and Wei ht.
This process has a very beneficial efiect on cellulose acetate fabrics. Apart from the increase of volume and weight it reduces the slipping of'the fabrics and it conveys to the fabrics a fire-proof character or rather very heat resistant character, as it is a well known fact that cellulose acetate silk fabrics melt with a too hot an iron. After the ap lication of this treatment no such melting ta es lace by treatment with a hot iron. It also uces the infiammability of the fibers, fabrics and articles. Furthermore, for instance, a circular knitted fabric made with cellulose acetate silk and treated according to this process will show reduction in the laddering capacity of the fabric when treated according to the above process.
Instead of cellulose acetate, other cellulose esters of organic nature, or cellulose ethers can be used such as the butyrate, propionate, methylate, or ethylate of cellulose, and this process can done with the fiber alone or fabrics consisting of 100% cellulose acetate or cellulose esters or ethers, or fabrics containin partly cellulose acetate and partly other bers like silk, etc.
For convenience the fibers, fabrics or other.
articles will be designated the claims as materials. Also to avoid alte'rnativeness of expression, the cellulose esters, ethers, and the like, will be generically termed organic substitution derivativesof cellulose. t
Insteador' artly instead of di-sodiuin hydro en phosp ate and sodium. silicate-,tannic aci can be used in above examples. The term fweighting is used in the appended claims in the ordinary technical sig- ,whichconsists in swelling and impregnating :the metal in said material 'said material with a salt of a weighting metal in solution, and subsequently treating to fix as an insoluble salt.
