dyebath/auxiliary bath reuse are demonstrated on a pilot-scale to be a feasible, economical alternative to conventional batch dyeing processes. atmospheric disperse dyeing of nylon and polyester carpet and nylon pantyhose, and pressure disperse dyeing of polyester yarn packages have all been demonstrated as suitable candidates for plant incorporation of the reuse techniques. good lot-to-lot shade correlations were also obtained with reuse of low-temperature reactive dyebaths and fixation baths on 100 cotton, and with reuse of combined high-energy reactive/disperse dyebaths and fixation baths on cotton/polyester knit fabrics. further computer program development is required, however, before industrial shades can be matched with the reactive dye reuse system. substantial saving in energy, dye, chemical, and water/sewer requirements demonstrated, and cost/benefit analyses based on the pilot-scale data and industrial information indicate a recovery of capital investment of less than one year for all of the systems investigated on incorporation of dyebath/auxiliary bath reuse. 14 refs
