'Green' computer colour matching system for pollution prevention in textile wet processing.

摘要

The ecological and toxicological properties of various dye classes as well as the impact of different dye classes on the environment has been studied preliminarily with reference to a total number of 380 Safety Data Sheets (SDS) obtained from 2 reputed environmental aware dyestuff suppliers. The purposes of this preliminary study are to study the quantitative and qualitative characteristics of different dye classes and to choose a specific dye class for further analysis. The results showed that each dye class produces waste of vastly differing quantities and characteristics. Also, reactive dye class has been identified for detailed study.; Six important pollution parameters of 15 dyes from 2 different series of dyes (Cibacron F and Cibacron LS) have been examined so as to establish the waste indicator database.; The best fit mathematical model used in regression analysis has been predicted for describing the relationship between each pollution parameter of the dye and the corresponding pollution parameter of the dyeing effluents.; A new breed of Computer Colour Matching (CCM) system called “Green” Computer Colour Matching (GCCM) system has been developed by incorporating the waste indicator database and the established mathematical models into a traditional CCM system. The detailed mathematical steps required for colourant formulation and the programming logic used for the development of the “Green” Computer Colour Matching (GCCM) System has been discussed. The algorithm of colourant formulation and recipe correction has been described thoroughly and Matrix Algebra has been used to solve the colourant formulation equations. A General Pollution Index (GPI) representing the overall pollution information of the dyeing recipes has been created by the summation of the normalised pollution indicators. Microsoft Visual Basic (VB) has been chosen to create the GCCM program. (Abstract shortened by UMI.)
