Abstract
Bast fibres have good strength therefore, used for ropes, yarns, paper and textiles. Compared to the other natural and man-made textiles fibres, silk and wool fibres are certainly supreme. Wool is highly desirable textile material due to its useful properties such as warmth, excellent resilience and absorbance where as silk has good strength and luster. Present study was conducted to study the properties of girardinia, muzaffarnagari wool and mulberry silk waste fibres and also to improve appearance, feel, aesthetic appeal and performance of girardinia fibre through blending with muzaffarnagari wool and mulberry silk waste fibres. Physio-chemical properties of these fibres were studied and compared. Yarns were prepared on Bageshwari Charkha from pure girardinia and different proportion of girardinia fibres with muzaffarnagari wool and mulberry silk waste fibres viz. 100:00:00, 25:65:10, 45:45:10 and 65:25:10. Physical properties of pure giraradinia and blended yarns of girardinia, muzaffarnagari wool and mulberry silk waste fibres were evaluated and compared. Yarns were dyed with direct, acid and reactive dye and their colour fastness was tested against light, washing and crocking. Pure girardinia and blended fabrics were prepared through knitting and their physical properties were also assessed. Different products were developed and their economic cost was also estimated. Findings of this study showed that blending of girardinia, muzaffarnagari wool and mulberry silk waste fibres brings a about a favorable improvement in the properties of resultant fabric. Blended fabrics has comparatively less weight, better insulation power, greater moisture content and enhanced aesthetic appeal than the fabric made from pure girardinia fibres. Thus from present study it can be concluded that 45:45:10 girardinia, muzaffarnagari wool and mulberry silk waste fibres blend proportion is best in all respect i.e., from performance and good aesthetic appeal at reasonable cost.
