One of the most noticeable bast fibre crops is roselle, which is widely grown in Assam. The scientiï¬c name for Roselle is Hibiscus sabdariffa L., and the plant is from the Malvacea family. Roselle found abundantly in tropical areas. It is a perennial shrub yielding fibre from the bark of the canes which provides excellent raw material for blending with the natural and synthetic fibres. It is an annual, erect, bushy, herbaceous sub shrub that can grow up to 8 ft (2.4m) tall and diameter of stem 2.0-4.0 cm at three different levels, viz. bottom and top, with smooth or nearly smooth, cylindrical, typically red stems. The morphological characteristics and chemical analysis showed their suitability as good textiles materials. The physical properties of Roselle fibre exhibited high tenacity, high luster and brightness. It has resistance to heat, light, acid and alkali etc. The fibre materials were capable of producing excellent blended fabrics. Roselle blended with different types of other cellulosic fibres showed good results, but 50:50 blends showed the best result than 25:75 blends. The tensile strength of 50:50 blends ranged from 20-30 g/tex for different blends. Therefore, blending of roselle with other cellulosic fibres in different proportions offers excellent scope for producing a variety of materials for different uses.
