Description
fiice 2,872,279 Patented! Feb. 3, 1959 DYEING PROCESS George Wiseman, Fairlawn, N. J., assignor to Ciba Company, Inc., New York, N. Y., a corporation of New York No Drawing. Application March 30, 1953 Serial No. 345,726
1 'Claim. (Cl. 8-55) The present invention relates to a novel dyeing assistant composition which is highly useful in facilitating the dyeing of Dacron (polyester condensation polymer from ethylene glycol and terphthalic acid or methyl terephthalate) and Dynel (copolymer of about 60% vinyl chloride and 40% acrylonitrile) textile material.
The novel composition comprises orthophenylphenol, pine oil and turkey red oil (about 50% sulfonated), preferably in the ratio of about 10 to about 8 to about 7, respectively.
A feature of the novel composition is that it can be directly added to the dyebath and disperses therein readily Without separation of its components, in spite of the insolubility of orthophenylphenol and pine oil in water. It readily disperses when diluted with water over a wide range of dilutions and maintains its stability. It
.is particularly useful in dyeing Dacron staple fiber in the form of loose stock or tops. It is not necessary to pre-dissolve the product with hot caustic .and to acidify between the pre-treatment and the dyeing as in the case of paraphenylphenol. In addition, the novel composition imparts a soft and lofty hand to the textile material.
The following example will serve to illustrate the preparation of the novel composition;
Example 1 32 parts of pine oil 28 parts of turkey red oil (50% sulfonated) 40 parts of orthophenylphenol are mixed together. A clear, pale, straw-colored liquid is obtained. The parts are by weight.
In applying the novel composition as a dye assistant, the required amount of the composition is dispersed in -10 times its own weight of water at 80 F. The quantities required will vary with the depth of the dyeing desired. Thus, for light and medium shades on Dacron about 5-10% of the dyeing assistant, based on the weight of the fiber, is employed, while for heavy shades is used.
Thoroughly scoured Dacron is then subjected to the aqueous dispersion for 2040 minutes at room temperature or 110-120 F. To the bath are added the selected dispersed dyestuffs, the temperature gradually raised to the boil and the dyeing continued for 1 to 1 /2 hours. Suitable dyestuffs are the acetate dyestuffs, which prior to their addition to the assistant bath are dispersed by any suitable dispersing agent, e. g., by Solvadine G (sodium alkylaryl sulfonate).
After dyeing is complete, the goods are rinsed with warm water, given a scouring in a scouring bath, e. g., one containing about 2% Solvadine G and l-5% soda ash based on the weight of the goods. The scouring treatment is carried out at 140-205 F. for 30 minutes. The goods are then given a final rinse with water, hydroextracted and dried.
The depth and shade of the dyeings produced .are highly improved and in addition the goods are left with a soft and lofty hand.
The following examples illustrate the dyeing process employing the new dyeing assistant.
Example 2 Dyeings were made on IO-gram spun Dacron skeins at a bath volume of 30:1 with 15% of the dyeing assistant illustrated in Example 1, and 2% of each of the following acetate dyestuffs:
l-hydroxy-4-amino-anthraquinone, 4-amino-4--nitro-azobenzene, 3-methyl-6-hydroxy-5 '-acetylamino-azobenzene, 1,4, 5,8-tetramino-anthraquinone.
The skeins were pretreated for 20 minutes at F. in 275 ml. of water containing the dyeing assistant. The dyestulf, dispersed with 1% Solvadine G, and 25 ml. of hot water, was then added and the temperature of the bath raised to 212 F. Dyeing was continued at the boil for one hour. Following dyeing, the skeins were rinsed .and then scoured for one-half hour at 205 F. with 5% caustic soda and 2% Solvadine. All percentages are based on skein weights.
Example 3 Dyeings are made in the identical manner as described in Example 2 on Dynel skeins except that only 25% of the dyeing assistant composition is employed.
The depth and shade of the dyeings produced with the novel dyeing assistant are highly improved and in addition the dyed materials are left with a soft and lofty hand.
I claim:
A process for dyeing polyethylene terephthalate textile material, which comprises pretreating the aforesaid textile material with a composition comprising orthophenylphenol, turkey red oil (about 50% sulfonated) and pine oil dispersed in an aqueous medium, adding a dispersed cellulose acetate dye thereto while the textile material is still therein, and subjecting the pretreated material to the resulting dyebath.
