H of the printing paste, treatment time and temperature of enzymatic treatment as well as the viscosity of the printing paste on colour discharge studied. The optimum conditions for discharge printing are found to be 4.5 . p. H, 60°C temperature, 1 h time of treatment, and the 90.4 poise viscosity at a shear rate of 31.61s. −1. The Each printing paste contains three basic ingredients: Dyestuff Thickener Auxiliaries 3 BASIC COMPOSITION OF EACH PRINTING PASTE Thickeners The most important and most responsible ingredient of any printing paste is a thickener.The thickener allows dyes and other components of a printing paste to be printed onto textile substrate in the contours of the The four main methods of textile printing are block, roller, screen, and heat transfer printing. In each of these methods, the application of the color, usually as a thickened paste, is followed by fixation, usually by steaming or heating, and then removal of excess colour by washing. Printing styles are classified as direct, discharge, or resist. These physical and chemical specifications are very precise and require the development of textile ink jet ink formulations, which differ from normal printing pastes, in that they cannot contain the majority of chemicals, required to achieve color yield, definition or color fastness. 3. DIFFERENT STYLES OF PRINTING There are three basic approaches to printing a color on a fabric 1. DIRECT PRINTING 2. DISCHARGE PRINTING 3. RESIST PRINTING. 4. DIRECT PRINTING • In this type of printing dye is applied onto the fabric by carved block, stencil, screen, engraved roller etc. Printing method All pigment printing auxiliaries and colors were mixing with motorized high speed stirrer. After preparation of printing paste were applied onto fabric by using laboratory hand screen printing technique. The printed fabric dried at 110°C for 3 minutes and cured at 150°C for 5 minutes. Crosslinkers are not the only source of formaldehyde in textile printing paste. It is generally also present in acrylate dispersions employed as binders and sometimes in the synthetic thickeners. Formaldehyde in acrylate dispersions is due to: a) the N-methylolacrylamide or N-methylolmethacrylamide crosslinker monomers in the polymer dispersions printing results were also investigated in the scope of the study. ZHOU Qiu-bao "Discharge printing of the real silk fabric with vat dyes", Journal Of Textile Research. Discharge printing of the real silk fabric was performed with vat dye paste for printing the patterns and vinyl-sulfone reactive dye for the ground. The effect of vat dyes, The application of disperse and reactive dyes in textile printing has met with worldwide interest. This combination of two dyes can be fixed . in a single process. Problems faced are fewer than with other dyes as printing paste , as well , pH level was adjusted at different levels (5-6-7-8), in order to determine the most suitable pH degree impression of paste on fabric using printing methods, drying of fabric, fixing the printing with steam or hot air (for pigments), after process treatments. Preparation of cloth for printing [ edit] Cloth is prepared by washing and bleaching. For a coloured ground it is then dyed. The fabric is placed on the printing table of flat screen-printing machine. The table is made of soft by laying on it. Then the screen is placed on the sample fabric. The printing paste is taken on the screen perforation. Thus we can find the printed fabric with a smooth woode
