Description

Patented May 19, 1931 PATENT OFFICE HENRY DREYF'US, 01 LONDON, ENGLAND TREATMENT OF CEIALULOSE DERIVATIVES OR PRODUCTS MADE THEREWITH No Drawing. Application filed March 4, 1927, Serial No. 172,921, and in Great Britain March 16, 1926.
This invention relates to the dyeing, printover those heretofore in use in that the coloring or stencilling' of artificial filaments, threads, yarns, fabrics, films or other products made from or containing cellulose 5 ethers.
yarns, fabrics, films and other products made from or containing cellulose ethers, for
example, methyl, ethyl, or benzyl cellulose,
or the corresponding condensation products of cellulose and glycols and other polyhydric alcohols, said condensation products being also herein included under the term ethers. It has now been discovered that when goods made from or containing cellulose ethers are loaded with a metallic salt or salts or compound or compounds, that is or are insoluble in water, such goods display an increased afiinity for dyestuffs, coloring matters or other .coloring compounds.
According to my invention, therefore,
goods made of or containing cellulose ethers,
are loaded with a metallic salt or salts or compound or compounds that is or are insoluble in water. preferably such as act as loading agents for natural silk, and are afterwards dyed, printed or .stencilled with dyestuifs, coloring matters or other coloring compounds in any suitable way.
The loading agents may be deposited on the goods by treatment in succession with a bath containing in solution a salt or salts. of a metal or metals such as tin, zine, tungsten, or aluminium and a bath containing a solution of phosphate, silicate, tannin or other compound or compounds adapted to deposit the metal or metals as an insoluble salt or salts or compound or compounds upon the goods.
The loading operation may be repeated, it being found that with each successive loading operation the increase in the capacity of the goods for absorbing dyestuifs becomesgreater and greater.
The goods, after they have been loaded in this manner, may be dyed with direct, acid, basic and other dyestuffs. V A
The process presents a marked advantage ing of the goods is of greater depth and brilllancy. The uniformity of the coloring also leaves nothing to be desired, while the colors produced. in accordance with this invention may readily be discharged by the usual processes.
Ewample 1 kilo of methyl or ethyl cellulose yarn in hanks is treated for one hour in a bath of stannic chloride of 33 B., the bath bein maintained at a temperature-of about 50 l The yarn is removed from the bath, and washed thoroughly with cold water. The yarn is now entered in a bath of di-sodium phosphate of 3 to 6 B. After treatment in the bath for hour at a temperature of 40-60 C. the yarn is removed and washed with warm water. The loaded yarn is then dyed in a bath containing about 1 per cent of dgestuff and 2 to 3 per cent of acetic acid, the ath being maintained at 4060 0.; alternatively, a bath containing a direct dyestuff together with Glauber salts or other assistant may be used.
Methyl or ethyl cellulose fabrics may be loaded and prepared for dyeing or stencilling or printing with printing pastes by treatment in successive baths of stannic chloride and di-sodium phosphate in the man- I ner described in the foregoing example.
If a heavier loading and an enhanced affinity for dyestuffs is desired, the loading operationmay be prolonged or may be repeated as often as desired or advisable.
The process is not limited to the procedure set forth in the preceding example, but may vary widely therefrom without departing from the invention. The process, moreover, is applicable to the dyeing, printing or stencilling of mixed yarns, fabrics or materials contalning filaments or yarns of cellulose ethers associated with other fibres or yarns, such as cotton or other cellulose fibres (natural or artificial), wool, and silk.
The term loading is used in the appended claims in the ordinary technical signification in which it is employed in connection with natural silk, that is to say, to connote the operation of increasing the weight and volume of the material under treatment; it does not include the production of such relatively small increases in weight as may be as sociated with processes of dyeing, such for example as those effected with the aid of mordants.

2. Process of dyeing material containing a cellulose ether, which comprises a loading operation wherein the material is swelled and impregnated with a solution containing a salt of a loading metal, and the material is treated with a solution adapted to fix the metal therein as an insoluble compound, and a subsequent operation comprising the application to the loaded material of a coloring matter that has but little aiiinity for the unloaded cellulose ether material.
3. Process of dyeing material containing a cellulose ether, which comprises a loading operation wherein the material is swelled and impregnated with a solution of a chloride of a loading metal, and the material is treated with a solution adapted to fix the metal therein as an insoluble compound, and a subsequent operation comprising the application of a coloring matter to the loaded material.
4. Process of dyeing material containing a cellulose ether, which comprises a loading operation wherein the material is swelled and impregnated with a solution of stannic chloride, and the material is treated with a solution adapted to fix the tin therein as an insoluble compound, and a subsequent operation comprising the application to the loaded material of a coloring matter that has but little affinity for the unloaded cellulose ether material.
5. Process of dyeing material containing a cellulose ether, which comprises loading the material by an operation in which the material is treated with a heated solution containing a chloride of a weighting metal and afterwards with an agent adapted to fix the metal in the material as an insoluble compound, and finally dyeing the loaded material with a dyestufi' that has but little afiinity for the unloaded cellulose ether material.
