Abstract/ Executive Summary:

The experiment was conducted during the year 1991-1992 at Bangladesh Jute Research Institute Dhaka, Spinning Department to blend jute with other natural/man-made fibers in existing jute processing systems.BWD quality jute fibers was selected for blending with Rayon fiber. The jute fibers was softened with normal emulsion (79.7% water, 20% oil and 0.3% emulsifier). The softened fiber was divided into two samples. One of them was blended with rayon which was one manually on the Breaker Card feed lattice in the ratio of 10:90, Rayon/jute and processed through the existing jute processing stages. Some of the results are interesting and encouraging which seems to be implemented in jute industry for producing quality yarns. The blended yarn having 5.0 TPI exhibited higher tensile strength than the other two blended yarns. Moreover, the quality ratio of the same sample was also increases from the other two blended yarns.

Start Date: 00-00-1991

End Date: 00-00-1992

Program Area: Postharvest and Agro-processing

Commodity: Jute

Objectives:

To increase the diversified uses of jute.

Methodology:

BWD quality jute fibers was selected for blending with Rayon fiber. The jute fibers was softened with normal emulsion (79.7% water, 20% oil and 0.3% emulsifier). The softened fiber was divided into two samples. One of them was blended with rayon which was one manually on the Breaker Card feed lattice in the ratio of 10:90, Rayon/jute. The blended sliver was processed through the existing jute processing stages and finally 6 lbs/spy. Quality yarns having 4.5, 5.0 and 5.5 TPI. were spun on the apron draft spinning frame. The second sample was processed through the same processing stages and yarns of same quality were spun on the same spinning frame. Then the spun yarns were tested to assess their physical properties.

Achievement/Findings:

The comparative study of the results showed that tensile strength of yarns produced from 100% jute was higher than that of yarns produced from blended sample. The quality ratio of 100% jute yarns was also better than that of blended yarns. The extensibility of blended yarns had improved from that of 100% jute yarns. Three different twist levels were used to observe the effect of twist on yarn quality. The blended yarn having 5.0 TPI exhibited higher tensile strength than the other two blended yarns. Moreover, the quality ratio of the same sample was also increases from the other two blended yarns.
