Natural screen printing ink comprises natural rubber latex and soil colorants
Screen printing ink is comprised of three main components: binder, colorant and additive. A newly developed screen printing ink needs to be more environmental friendly or non-toxic. This research aimed to produce water- based screen printing ink by using natural materials. Natural rubber latex was selected for substitute chemical binder. Three Types of soil were used as colorant: black, red and yellow. Cassava starch was used as dispersing agent to help disperse colorant and binder. Ink formulas of natural rubber latex, cassava starch and soil colorants were studied by printing on cotton fabric with screen block number 48. The density and CIE L * a * b * of the printed on cotton fabric were measured, the best formula was selected for further test for the qualities of printed on cotton fabric. The results showed that natural screen printing inks that had ratio in weight of soil colorant: cassava starch: natural rubber latex at 8:10:20 is the best formula, the printed on cotton fabric showed the best qualities. The CIE L*a*b* values of printed cotton fabric from screen printing ink with black soil colorant were L*=49.70, a*= 7.37 and b*17.95; red soil colorant were L*=62.58, a*25.08, b*24.56; yellow soil colorant were L*=76.90, a*=8.54, b*=31.51. Natural screen printing ink from soil colorant and natural rubber latex that printed on cotton fabric showed that font TH SarabunPSK could be seen clearly at 18 point up of positive image and negative images at 20 point up. However, yellow soil could not give details of the image on cotton fabric, positive image was clearly at 0.25 point up and negative image was clearly at 2 point up. Natural screen printing ink was tested for adhesion on cotton fabric by washing the printed with detergent in washing machine. The results showed that the printed density before washing of black, red and yellow soil colorant were 1.18, 0.98, 0.80 and after washing were 1.15, 0.96, 0.77, respectively.
