摘要
To decline environmental load from waste water by dyeing, we examined dyeing fabric with clay pigments. The clay pigments made in France and used as building materials, and cotton fabrics are used in this examination. We selected No.4 Indian Yellow pigment, mainly constituted by ferric oxide for dyeing material. Dyeing temperature and time, amount of pigments, frequency of dyeing process, aging and soaping condition were varied and examined its effect. We measured the Lab color space (CIE L*a*b*) values and compute K/S values of dyed fabrics. Composition of pigments and dyed fabrics were analyzed by using XRF. Shape of pigments was observed and particle size distribution was analyzed by using SEM, zeta-sizer. Finally, we examined color fastness to washing and rubbing as the consumption performance of dyed fabrics. Satisfactory color was gained follow process, repeating two cycle; dye,dry (24 +/- 4hours), rinse (seven times with 50ml extrapure water), at 50 for 60minutes, with 0.5g pigments per 50ml water. And perform aging (24 4hours), soaping. Consumption performance was satisfaction in washing.
