Printing of Silk Fabric with Reactive Dye Using Flour of Wild Taro Corm as a Resist Printing Paste

Abstract

The present study was undertaken to use flour of wild taro (ColocasiaEsculenta (L.) Schott) as a resist printing paste for silk fabric and using reactive dye as a dyestuffs. The K/S values, whiteness index and sharpness of printed silk fabric were studied. The washing, water, perspiration, light and rubbing fastness of the printed fabric was also evaluated. From the present work it can be concluded that the pattern at resist printing area of silk fabrics show sharpness and whiteness. Colour fastness to water and perspiration were ranging between poor to fair level. Printed fabric exhibited fair to good level in washing, rubbing and light fastness. The advantages of this product are environmental friendly that is non-toxic fumes; production cost is lower, instance application and creative process enhancement in textile production.

An Overview of Printing Textile Techniques

“…[4,[13][14][15][16][17][18][19][20][21][22][23][24][25][26] The main objective of printing is to create colourful patterns with sharp borders on textile fabrics without any dye spilling beyond the design motif's borders. [27] Textile printing is defined as a regulated technique of colouring cloth in specific patterns or motifs by employing specialized printing techniques and machinery. [28,29] it is also the process of creating a colour pattern or drawing on textile materials.…”

“…Resist printing technique is still as popular now as they were in the past. [27] Resist printing style gets its name from the fact that the cloth is printed with a compound that it is used to inhibit dye absorption on cloth by preventing dye penetration or fixing. [4,7,10] Resist printing is a printing technique in which the pre-treated cloth is first printed with the resist agent and then coloured by dyeing.…”

“…[4,7,10] Resist printing is a printing technique in which the pre-treated cloth is first printed with the resist agent and then coloured by dyeing. [12,27] Only the areas that are not coated with resistant paste will be affected by a dye, resulting in a pattern on a colourful background. [4,28,48] A multicolour pattern can be made by placing a paste containing a material resistant to second dye on already coloured cloth.…”

“…[7,34] Resist mechanism can be physical or chemical, with a combination of both types of resist agent ensuring optimum efficacy. [6,27,34] Coloured resists necessitate the addition of dyes or pigments to the print paste that are properly fixed in the presence of the resist agent, either before or during the process of fixation the ground colour. [27,34] The styles of resist printing materials are identical to those of the discharge technique, but the resist printing method has an advantage in the range of dyes that may be chosen for ground colour, whereas dyes used in the discharge method only focus on those with instability that can be readily destroyed.…”

“…Chemical resist printing Chemical resist which is shown in Figure 9: Chemical resistprevents fixing of the dye into the fabric. [27,34] It is favourable for (1) dye dissolution (oxidative or reductive), (2) dye insolubility (through the addition of anti-solution agent), and (3) blocking the dye site on fibres.
