The production of printed textiles

It is used in the manufacture of polyvinylpyrrolidone (PVP), in the manufacture of copolymers with, for example, aciv lic acid, acrylates, vinyl acetate and acrylonitrile and in the synthesis of phenolic resins. About 10-15% of the monomer is used in the pharmaceutical industry for the production of PVP-iodine complex used as a disinfectant. It is also used as a reactive solvent of ultraviolet-curable resins for the production of printing inks and paints as paper and textile auxiliaries, and as an additive in the cosmetics industry (Harreus, 1993). 

Magnesium acetate also has uses as a dye fixative in textile printing, as a deodorant, disinfectant, an antiseptic in medicine, and as a reagent chemical (see Disinfectants AND ANTISEPTICS Textiles) (6). In the United States, Hoescht-Celanese and Tennessee Eastman are the principal producers of magnesium acetate. These companies make about 36,000 t/yr, which is largely used in-house for the production of cellulose acetate. 

Use. Titanium dioxide is mainly used in the production of paints and lacquers (55—60%), plastics (15—20%), and paper ( 15%). Other apphcations include the pigmentation of printing inks, mbber, textiles (qv), leather, synthetic fibers, ceramics, white cement, and cosmetics. 

The term textile printing is used to describe the production of colored designs or patterns on textile substrates through a combination of various mechanical and chemical means. In printing on textiles, a localized dyeing process takes place, whereby in general the chemical and physical parameters of dyeing apply. 

Dichlorobenzidine is a gray-to-purple colored crystalline solid. It changes from a solid to a gas very slowly. 3,3 -Dichlorobenzidine salt, the major form in actual use, is a stable, ofif-white colored crystalline solid that does not evaporate. Neither 3,3 -dichlorobenzidine nor its salt occur naturally in the environment. They are manufactured for use in the production of pigments for printing inks, textiles. 

Dichlorobenzidine is used primarily in the production of yellow, and some red and orange pigments for the printing ink, textile, paper, paint, rubber, plastic, and related industries (EPA 1979a). As of 1983,... 

The replacement of classical textile printing techniques by digital printing techniques (ink-jet and bubble jet) is in full progress. Present limitations result from the availability of appropriate formulations of inks/dyes and fixation techniques. The comparable low production speed and limitations with regard to the quality of the textile material can be expected to be overcome within the next 5-10 years.
