Jute, a renowned biodegradable and sustainable textile fibre, plays a pivotal role in environmentally conscious textile production. The purpose of this study was to investigate the effects of the woolenization process on the qualitative attributes of jute yarn, such as yarn evenness, and tensile and functional properties, with a special focus on the development of wool-like properties. Yarn samples were meticulously prepared from white jute fibre, categorized into three distinct count groups (C8, C10, and C12), and subjected to four treatment categories: untreated (U), woolenized (W), bleached (B), and dyed (D). The results showed that the woolenization process impoverished yarn evenness, with a significant 15.2% increase in CVm for WC8, 74% and 88.6% increase in Thin (-50%)/Km and Thick (+50%)/Km, respectively, for WC10. For tensile properties, a 27% reduction in tenacity and 176.5% remarkable elongation improvement were noted for samples WC10 and WC12, respectively. Furthermore, the development of wool-like properties was noteworthy in functional properties, including a 38.8% increase in Specific Volume Index (SVI), and a 12.8% reduction in moisture content was marked for WC8. The woolenization process also had an adverse effect on jute yarn count and quality ratio, with a deterioration of 12.5% and 32.2% marked for sample WC10, respectively. The results suggest that the bleaching process performed after woolenization negatively impacts yarn evenness. However, dyeing after woolenization and bleaching can enhance overall yarn quality. The outcome of this study will promote the use of natural fibre, and jute over synthetic and natural wool fibres.

In the Weaving department of the Mechanical Processing Division of the Bangladesh Jute Research Institute, Dhaka, the characteristics of union fabric made of jute and cotton with a fancy weave design were investigated. The goal of this study is to create jute-cotton union fabric with a Mock leno weave pattern for a variety of applications. 10/2 cotton yarn was used for the warp, while 17 lbs/spy jute yarn was utilized by the weft. The elaborate union fabric was created using a Mock leno weave pattern with a repeat size of 12 by 12.

The object of this study is the application of basic dyes on jute fabrics at different temperature and fastness analyses of dyed jute fabric. Hessian jute fabric is collected from jute weaving mill then jute fabric is undergone pretreatment process. Pretreated jute fabric is dyed with basic dyes at various shade percentage such as- 5%, 2%, 4%,5% shade variation at different temperature. Then fastness property is analyses by color fastness to wash, color fastness to rubbing, color fastness to light. It showed that at 65oC temperature and 4% shade variation basic dyes gives good color fastness on hessian jute fabrics.

In this analysis jute cotton blend denims performance at enzyme wash to 35 times respective laundering, in friction and roughness properties where 5 times laundered sample showed smoother surface in both inner and outer surface. In bending properties, 5 times laundered sample was found second lowest Bending Average Rigidity (BAR) and Bending Work (BW). In compression, highest Compression Average Rigidity (CAR), Recovery Average Rigidity(RAR) and less energy requirement Compression work (CW) to compress in both inner and outer surface was found in 5 times laundered sample. In Sensorial Comfort Aspect (SCA), 5 times laundered sample was found smoother surface property, quite higher bending property and higher compression average rigidity. Therefore, 5 times laundered sample was good sensorial comfort among all the samples. In Maximum Thermal Flux (MTF), 20 times laundered sample gives most warm feeling at inner surface because it provides minimum heat flux which ensure warmness in skin-garment micro environment. For thermo physiological comfort aspect, only 20 times repetitive laundered sample found maximum thermo physiological comfort among all samples. Thus, Jute-Cotton blend denims performance at enzyme wash to 35 times repetitive laundering up to 20 times repetitive laundering sample reported good results and the protruding fibre of jute was visible excessively on the surface.
