The Sterilization of Wool and Its Effect on Physical and Chemical Properties of a Wool Fabric^
نویسنده
چکیده
From the time wool grows on the sheep, on through the stages of manufacture and wear, the fibers are subject continually to contamination with micro-organisms. Included in this micro-organic flora may be the pathogenic organisms responsible for disease. There may also be other groups less dangerous to health but capable of multiplying rapidly under favorable conditions and causing the wool fibers to be stained with mildew or to lose strength and deteriorate in other ways. The utilization of wool therefore may be seriously affected by the action of micro-organisms. Oftentimes wool must be sterilized to free it of pathogenic organisms, and also of the nonpathogens which damage it as already indicated. Also in bacteriological studies of the effect of these microorganisms on the fibers, it is essential that the w^ool be sterilized. Many of both these groups of organisms have a sporulating stage, during which they are very resistant to the usual means of sterilization. It is generally believed that these spores are not killed until

Colorimetric properties of wool dyed with Cochineal: Effect of Dye-bath PH
In the present work an evaluation was carried out on the effect dye-bath pH and mordant type on the obtained shades and fastness properties in wool dyeing with cochineal. In this way wool samples were first mordanted with four different mordants and subsequently dyed with cochineal at different levels of dye-bath pH. Colorimetric evaluations were carried out and fastness properties of the dyed ...
متن کاملImproving Colorant Absorption from Pistachio Hulls on Wool Fiber Using Protease Enzyme
Nowadays, textile processing based on biotechnology has gained its importance in the view of stringent environmental and industrial safety conditions. The use of protease enzymes in protein fibers to improve some physical and mechanical properties is particularly interesting. In this research, wool yarns were first treated with different concentrations of protease enzymes in aqueous solution in...
متن کاملFunctional Dyeing of Wool with Natural Dye Extracted from Berberis vulgaris Wood and Rumex Hymenosepolus Root as Biomordant
In this study, a functional colorant, Berberine, extracted from Berberis vulgaris wood was applied onto wool fiber using the extract of roots of Rumex Hymenosepolus as biomordant. The effect of treatment variables on the color strength of dyed fibers was examined. The fastness properties of dyed wool against washing, light, dry and wet rubbing were evaluated. Dyed samples were tested for an...
متن کاملImpact of Chitosan-poly(amidoamine) Dendreimer Hybrid Treatment on Dyeing and Color Fastness Properties of Wool Yarn with Madder Natural Dye
In recent years, chitosan and its different derivatives have been extensively used in surface modification and functional finishing of textiles. In this study, wool yarns used in handmade carpet were treated with different concentrations of chitosan-poly (amidoamine) dendrimer hybrid (Ch-PAMAM) and characterized by scanning electron microscope (SEM), and their dyeing properties were investi...
