Sažetak
About 100000 tons/year or less than 0, 2% of globally produced fibres is silk and the production is likely to continue falling. Nevertheless, all of the production processes involved in manufacture of silk are carefully and scientifically reviewed and improved to enhance economical and ecological viability. This paper reviews two of the most important processes in the production of silk, degumming and dyeing. Silk fibres were degummed by boiling off in soap solution and by using proteolytic enzymes. In order of determining efficiency and differences among these commonly used degumming processes, fibres were subsequently dyed by acid dyes C.I. Acid Red 18 and C.I. Acid Yellow 11 and metal complex dyes C.I. Acid Blue 193 and C.I. Acid Red 211:1. Obtained results showed significantly lower dye exhaustion for soap degummed fibres regardless of dye used or pH value of the fibres as a result of alkaline degumming conditions.
