Printing
Textile printing is the process of applying colour to fabric in definite patterns or designs. In properly printed fabrics the colour is bonded with the fiber, so as to resist washing and friction. Textile printing is related to dyeing but, whereas in dyeing proper the whole fabric is uniformly covered with one colour, in printing one or more colours are applied to it in certain parts only, and in sharply defined patterns.
In printing, wooden blocks, stencils, engraved plates, rollers, or silkscreens can be used to place colours on the fabric. Colourants used in printing contain dyes thickened to prevent the colour from spreading by capillary attraction beyond the limits of the pattern or design.
Traditional textile printing techniques may be broadly categorised into four styles:
Direct printing, in which colourants containing dyes, thickeners, and the mordants or substances necessary for fixing the colour on the cloth are printed in the desired pattern.
The printing of a mordant in the desired pattern prior to dyeing cloth; the color adheres only where the mordant was printed.
Resist dyeing, in which a wax or other substance is printed onto fabric which is subsequently dyed. The waxed areas do not accept the dye, leaving uncoloured patterns against a coloured ground.
Discharge printing, in which a bleaching agent is printed onto previously dyed fabrics to remove some or all of the colour.
Resist and discharge techniques were particularly fashionable in the 19th century, as were combination techniques in which indigo resist was used to create blue backgrounds prior to block-printing of other colours.[1] Most modern industrialised printing uses direct printing techniques.

Textile printing history
Textile decoration is an ancient art. It refers to the various processes by which fabrics are printed in colored design print fabrics. Examples of Greek fabrics from the 4th century B.C. have been found. India exported block

    Different dyes have different affinities. Since each component of a dye has its own distinctive affinities, each component will travel up the paper at its own rate. It seems from my results that blue has an affinity for the mobile phase as it quickly moved up the paper with the solvent. Red, on the other hand, seemed to have an affinity for the paper, as it did not travel as far as the other colors.…

    Permanent inks contain three main ingredients: colorant, carrier (solvent), and resin (polymer). Pigments do not fade like dyes and do not bleed through paper. Solvents for the old markers (up until the 1990 's) were nasty-smelling organic chemicals such as xylene. Nowadays, the solvent of choice is an alcohol (ethanol or isopropanol), which is more environmentally friendly and better smelling, while still evaporating quickly to prevent messy smearing, etc. Finally, there is a resin or polymer that is added as a "binder" that promotes adhesion. A permanent resin is not permanent unless it sticks like glue to most of the surfaces it is written on. The resin forms a film (once the alcohol evaporates) that allows the ink to write smoothly and uniformly on any surface (smooth or rough) while acting like glue for the pigment. Resins come in all shapes and sizes, typically, urethane acrylic resins are used (like those used in house paints).…

    The object on which the print is located can be dipped in or sprayed with a ninhydrin solution, which reacts with the oils in the print’s residue to create a bluish print. One of the drawbacks of using ninhydrin is that the reaction is very slow, often taking several hours for the print to become visible. To accelerate the reaction, the object containing the print can be heated to 80 to 100 degrees Fahrenheit (Thompson,…

    Archaeologists have found evidence of textile dyeing dating back to the Neolithic period. In China, dyeing with plants, barks and insects has been traced back more than 5,000 years.[1] The essential process of dyeing changed little over time. Typically, the dye material is put in a pot of water and then the textiles to be dyed are added to the pot, which is heated and stirred until the color is transferred. Textile fiber may be dyed before spinning (dyed in the wool), but most textiles are yarn-dyed or piece-dyed after weaving. Many natural dyes require the use of chemicals called mordants to bind the dye to the textile fibers; tannin from oak galls, salt, natural alum, vinegar, and ammonia from stale urine were used by early dyers. Many mordants, and some dyes themselves, produce strong odors, and large-scale dyeworks were often isolated in their own districts.…
