A combined scouring and bleaching process was developed for absorbent cotton preparation using crude enzyme. The substrate for crude enzyme preparation includes banana pseudo stem dry powder, cotton seed hulls and cotton seed meal in the ratio of 60:30:10. The crude enzyme was extracted from the fermented substrate and the pectinase and laccase activity recorded in the enzyme extract was 25 and 7 Units per ml respectively. Experimental trials were taken to prepare absorbent cotton from one kg of short staple cotton (var. Phule Dhanwantry) using High Temperature and High Pressure (HTHP) method and Open Bath (OB) method. The process conditions were cotton fibre and crude enzyme extract in the ratio 1:12, material to liquor ratio was 1:20, temperature (55ºC), time (40 min), pH (9.0) and wetting agent (0.1%). The absorbency recorded was 3 seconds (sink test) and whiteness index of 32(CIE standard) and 41 in HTHP and OB methods respectively. Moreover, the capital investment required for OB method is much less than HTHP method. Considering the large availability of cheap agro residue in the rural places, this eco-friendly, economical and simple enzymatic process could be easily adopted for rural entrepreneurship development, especially for rural women employment.
