A Comparative Study on the Dyeability of Stabraq (Milkweed) Fibers with Reactive Dyes
In this work, raw fibers of a local species of stabraq (milkweed) were scoured, bleached and blended with cotton fibers with a ratio of 75/25 (cotton/stabraq). The improved stabraq fibers, scoured and bleached cotton and the blended fibers were spun into fine yarns and then they were subjected to dyeing with two types of reactive dyes namely, cold brand and high exhaustion brand reactive dye at...
متن کاملRotation of cellulose ribbons during degradation with fungal cellulase
Degradation of bacterial cellulose with a commercial cellulase, Celluclast 1.5 L (Novo Nordisk), from the fungus Trichoderma reesei, causes a rotational movement of the cellulo:,c microfibrils. Purified cellulases (CBH I, CBH II, and EG II) do not induce rotation of bacterial cellulose, however, ratios of CBH I and EG II do cause rotation of bacterial cellulose. Equimolar amounts of CBH r or CB...
متن کاملTreatment of cotton with an alkaline Bacillus spp cellulase: activity towards crystalline cellulose.
We analysed the influence of several enzymatic treatment processes using an alkaline cellulase enzyme from Bacillus spp. on the sorption properties of cotton fabrics. Although cellulases are commonly applied in detergent formulations due to their anti-redeposition and depilling benefits, determining the mechanism of action of alkaline cellulases on cotton fibres requires a deeper understanding ...
متن کاملEnhancing the Dyeability of Polypropylene Fibers by Melt Blending with Polyethylene Terephthalate
Attempts were made to modify polypropylene fibers by melt blending with polyethylene terephthalate in order to enhance the dyeability of the resultant fiber. Five blends of polypropylene/polyethylene terephthalate/compatibilizer were prepared and subsequently spun into fibers. Three disperse dyes were used to dye such modified fibers at boiling and 130 °C. The dyeing performance of the blend fi...
متن کاملEnhanced Cellulose Degradation Using Cellulase-Nanosphere Complexes
Enzyme catalyzed conversion of plant biomass to sugars is an inherently inefficient process, and one of the major factors limiting economical biofuel production. This is due to the physical barrier presented by polymers in plant cell walls, including semi-crystalline cellulose, to soluble enzyme accessibility. In contrast to the enzymes currently used in industry, bacterial cellulosomes organiz...
