Textile printing color,

The process of textile print coloration can be divided into three steps. First, the colorant is appHed as pigment dispersion, dye dispersion, or dye solution from a vehicle caUed print paste or printing ink, containing in addition to the colorant such solutions or dispersions of chemicals as may be required by the colorant or textile substrate to improve and assist in dye solubUity, dispersion stabUity, pH, lubricity, hygroscopicity, rate of dye fixation to the substrate, and colorant-fiber bonding. The required viscosity characteristics of a print paste are achieved by addition of natural or synthetic thickening agents or by use of emulsions.

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. 

The high quality of the fastness properties is the basis for frequent pigment use in textile printing. Dry cleaning with perchloroethylene or washing has almost no effect on the color. P.Y.83, sometimes in the form of a preparation, is used for viscose spin dyeing, secondary acetate, and polyacrylonitrile. 

P.O.16 is not lightfast and durable enough to be used in paints. In this respect, it performs even more poorly than P.Y.12. Low-cost production, however, makes it a suitable colorant for rubber and for textile printing. 

P.R.12 textile prints are excellently lightfast 1/1 to 1/6 SD prints equal step 7 and 6-7, respectively, on the Blue Scale. However, the pigment fails dry cleaning tests and migrates considerably in PVC coatings. P.R.12 tolerates dry heat up to 150°C at 180°C, the pigment still largely retains its initial color value. 

P.R.150 is of limited regional significance. Depending on the area of application and on the reduction ratio, the pigment affords shades from bluish purple to carmine. P.R.150 is used in textile printing. In PVC coloration, which used to be its main market, it has been superseded by other products. 

P.R.212 was used throughout the graphics industry and for textile printing, as well as in specialized media, such as colored pencils. 

Incorporated in plasticized PVC, P.B.15, like other phthalocyanine pigments, is usually entirely fast to migration. Moreover, it provides excellent lightfastness. P.B.15 also finds use in various types of PUR foam materials as well as in rubber. Its redder and frequently cleaner shade compared to corresponding stabilized types makes it an equally useful pigment for other media. This applies especially for water-based systems. Textile printing, paper mass coloration, paper surface treatment, and paper pulp are areas of application as suitable for the use of P.B.15 as office articles, including colored pencils, blackboard chalks for schools, and water colors. 

P.R.194 is also used in textile printing, for instance in combination with carbon black, to produce shades of brown. It is both very lightfast and durable in these media. The coloration equal step 7 on the 8 step weatherfastness scale [8]. 

P.B.9 matches the standard cyan for three and four color printing (Sec. 1.8.1.1). The pigment is continually losing significance as it is being displaced by the similarly shaded [3-modification of Copper Phthalocyanine Blue. The latter offers a number of applicational and economical advantages. P.B.9 continues to be used in mass colored paper, textile printing, and in colored pencils. 

Manganous monoxide (MnO) is used for textile printing, ceramics, paints, colored (green) glass, bleaching, and fertilizers. It is also used as dietary supplement and reagent in analytical chemistry. 

Beside indigo itself, the indigoid colorant thioindigo and its derivatives are also important vat dyes, but because of the low affinity of vatted thioindigo dyes for the fiber, these dyes are used mainly in textile printing. 

Tie-dyeing is, like textile printing, selective dyeing. If a piece of wool is bound tightly with cotton strips and then dyed by immersion in a dye bath, only those areas exposed to the dye will take on its color. After the fabric is removed and allowed to dry, and when the strips of cotton are untied, the tightly bound areas show no color from the dye. Omitting dye from...
