Abstract:
Cellulose fiber extracted from pineapple leaf contains impurities such as
hemicelluloses, pectin and lignin that need to be removed from fiber to increase its
wettability. Generally, sodium hydroxide solution is used for this task in a process called
scouring. In this work, a multi-enzyme consisting of pectinase, xylanase and cellulase was
locally produced from Aspergillus sp. and was used for pineapple yarn scouring. Industrial
raw yarn was enzymatic scoured at pH 4, 50 oC for 30-120 minutes using various
concentrations (10-100%) of crude multi-enzyme and a yarn to liquor ratio of 1:50. For
comparison, sodium hydroxide scouring was also conducted on raw yarn at 100 oC for 10-
60 minutes using 0.05-0.25%NaOH and a yarn to liquor ratio of 1:25. Scoured yarns were
tested for various properties such as wettability, weight loss, cellulose content, yellowness,
dyeability and yarn strength. Results indicated that at optimal conditions, both scouring
methods provided successful outcomes. All scoured yarns showed evenly and
instantaneously wet with water and dyed yarns contained similar color shade as well as
color strength (K/S = 10.2 and 10.6). The enzymatic scoured yarn had lower yellowness
index (36) than the NaOH scoured yarn (45), but it contained approximately 1.45% higher
weight loss after enzymatic scouring.
