The purpose of this experiment is to test the effect of sodium hydroxide solution on Lucina plant seeds. Using different concentration of sodium hydroxide with crushed Lucina plants seeds, as well as printing pastes containing eco-friendly galactomannan gum and natural dye were isolated in containers. Investigations were carried on the rheological properties of each. Screen printing and burn-out style methods testing was also used to evaluate the efficiency of the obtained pastes. The test was conducted by printing on five different blends and pure wool. The results were concluded by calculating the percentage loss regarding weight, K/S of the colored area and tensile strength of the printed area. The results showed that all the pastes were categorized by non-Newtonian pseudo-plastic behavior . During simultaneous use, the pastes were successful printed by screen-printing and burn-out style methods. By increasing the sodium hydroxide concentration and/or the portion of wool in the material blend, the percentage loss in weight as well as tensile strength increases. The K/S of the printed area was determined by the nature of the component of the blend and was ordinarily higher on protein fabrics than cellulosic. Unique colors and attractive textures could be established by this technique. The higher the concentration of sodium hydroxide, causing % loss in tensile strength increases specially for woolen blends. To conclude, this eco-friendly technology has proven to be effective; energy and cost efficient; and with minimum harmful waste.
