Coloration Modeling and Processing of Commodity Plastic Buttons in Supercritical Carbon Dioxide

We examined the color processing of the commodity plastic buttons made of acrylic, polyester, nylon, and casein with scCO(2). The buttons’ dyeing color depth (K/S) was measured over a wide range of scCO(2) and correlated accurately with the response surface method. Moreover, we measured the solubili...

Sumario:We examined the color processing of the commodity plastic buttons made of acrylic, polyester, nylon, and casein with scCO(2). The buttons’ dyeing color depth (K/S) was measured over a wide range of scCO(2) and correlated accurately with the response surface method. Moreover, we measured the solubility of C.I. Disperse Red 22 in scCO(2) to formulate a dye-sorption model for the K/S value in the color processing of the plastic buttons. Finally, the dye-sorption model for the K/S value combining the dye solubility in scCO(2) with the dye diffusion inside the buttons successfully represented the color processing of the buttons.
