Özet

In this paper, water, materials, and energy consumption and costs for various cotton fabric pretreatment processes were examined based on mill and production conditions. Enzymatic processes save water, energy, and time over conventional pretreatments. Enzymatic scouring combined with activator-agent-assisted hydrogen peroxide (H(2)O(2)) did not generate electricity and time savings, but did save on water and steam consumption/cost. Steam, followed by water and electricity, was the most costly. Process temperature and water consumption were more important than process time for cost control. Activator agent use also increased recipe cost. Enzymes used in enzymatic processes are often relatively expensive, with total costs higher than conventional processes, although enzymatic processes offer significant water and energy savings. However, low-concentration pectinase processes resulted in less total cost than alkaline scouring.
