Blending is a mixing process where two or more different fibers are combined into the desired percentage. In a yarn spinning system, different compositions, lengths, diameters, or colors may be mixed to create a blended yarn. In this system, various lots of fibers are combined into a homogeneous mass before being spun into a staple fiber yarn. Usually, jute and cotton fiber are blended together to make jute-cotton blended yarn. The diversified use of jute is one way to blend yarn. A 30%: 40%: 30% ratio was used for making the jute-cotton-viscose blended yarn. A rotor frame in a cotton spinning line produced the jute-cotton-viscose blended yarn and 100% cotton yarn. The physical properties like count, yarn Lea strength, and CSP were measured for both jute-cotton-viscose blended yarn and 100% cotton yarn. Among them, the average count of jute-cotton-viscose blended yarn and 100% cotton yarn are found approximately the same, i.e., 6.0 and 5.89, respectively. However, the yarn lea strength and CSP of both samples are 318.6 lb, 208 lb, and 1876, 1246, respectively, for 100% cotton yarn and jute-cotton-viscose blended yarn, which are far different from each other. There is the consistency of CV%, SD, and PMD of the blended yarn as well as 100 % yarn. In this study, viscose was first introduced for the blending process with jute and cotton to produce a jute-cotton-viscose blended yarn, and the physical properties were compared with both yarns.

Cellulose is a natural linear chain homopolymer that is an abundant and common component in all plants. Partially pure depolymerized cellulose, known as microcrystalline cellulose (MCC), is synthesized by mineral acids hydrolysis from α-cellulose precursors obtained from fibrous plants such as jute. Virgin soft and hardwoods are used as the main source of cellulose for raw materials of MCC production. These can be replaced by jute fiber to a great extent as it is considered one of the most promising alternatives. A proximate analysis had been carried out to determine the percentage of cellulose, hemicellulose, fats, and lignin in cellulose by standard methods. The cellulose purity of BJRI Tossa Pat-8 (Robi-1) fiber is identified from FT-IR. The IR results of MCC analysis were indicated 3,337.40cm-1 for the moisture and 1656.45cm-1 for carboxyl groups. In thermogravimetry analysis, at the first phase, 20-95oC is associated with moisture release. The oxidation of Tossa Pat-8 (Robi-1) MCC occurred in the range of 200-400oC. The remaining 0.65% of inorganic materials ash, was obtained at 425oC. This study indicates the cost-effective isolation of MCC from Tossa Pat-8 (Robi-1) and that can be promisingly applicable in several fields such as coatings and membranes explosives, cellulose, textiles, adhesives, films, textiles, food and tobacco, films, pharmaceutical and cosmetics industry, which needs further research.
