Pigment printed textiles represent the highest percentage of all printed textiles. This is primarily due to the uncomplicated process and low cost of importing colored patterns to textiles with pigment system. The water insoluble pigment used in most cases as an aqueous dispersion, has no affinity to textile fibres and is not able to enter into chemical or physical reactions with the fibre. For the bonding of pigments to textile a bonding agent generally of a synthetic latex type, is incorporated in the print paste, which through its film forming properties holds the embedded pigment firmly or fibre surface. Due to the possibility of fixing, pigments to textiles without interaction with the fibre material this class of colorants can be applied to a greater variety of fibres than any other coloring matter this advantage largely accounts for the popularity of pigments in textile printing especially on fibre blends. The binding agent or "low crock" is a dispersion or solution of such polymers as poly(acrylic acid) derivatives and butadiene-styrene copolymers. In most cases a crass linking agent is applied in the same print paste, consisting of synthetic rosin types melamine- formaldehyde derivatives for added wash and crock fasteners. Both pigment dispersion and binding agents cross linking are incorporated into a clear emulse, or synthetic thickening solution. The clear concentration form which the clear is prepared contains such necessary auxiliary chemicals as dispersing agents emulsifiers, acid dovors, lubricants, protective colloid and synthetic thickening agents of the poly(acrylic acid) and maleic acid anhydride copolymer type. For emulsion clear printing mostly oil in water emulsions are used. Pigment print systems have a number of inherent limitations most notably the effect of the binding agent and cross linking chemicals on the hand and feel of the textile materials, also sometimes insufficient fastness to cracking, abrasion, washing and dry cleaning noticed especially in heavier shades and on large coverage and the sometimes objectionable property of pigments to camouflage fiber texture and luster pigments prints are fixed by heat treatment at 150-200oC in 1-5 min after coursing is generally not necessary. Synthetic lattices may be defined as aqueous dispersions of polymers particles produced by the process known as emulsion polymerization. Interest in these materials arose initially from the use of natural rubber latex and the prospect of making by synthetic means, a latex similar to the naturally occurring product. The earliest references to synthetic lattices probably date back to pre-1920 with the work originating in Germany. It has been noted by several reviewers that all the essential elements of emulsion polymerization were almost certainly known before World War 1. During the period 1930-35 emulsion polymerization was being established as a method of producing synthetic rubber lattices. Considerable advances were made during World war II in Germany and U.S.A. when continuous processes for synthetic rubber production were developed for styrene-butadiene (SBR) and acrylonitrile-butadiene copolymers to alleviate the shortage of natural rubber. Since then, many other types have come onto the market with polyvinyl acetate and copolymers, acrylics, and carboxylic - SBR types being the major products. Today, the annual consumption of synthetic lattices of all types is estimated at about 800 000 dry tonnes for Western Europe and a further 900 000 dry tonnes for U.S.A.
