Abstract/ Executive Summary:

The experiment was carried out at Dyeing and Finishing Department of Bangladesh Jute Research Institute in 1993. Hydrogen per oxide and mercerized jute fabrics were dyed with 2% reactive orange color dyed by a new method using pad dry technique. The wash fastness property, crease recovery angle and tensile strength of the dye jute samples were measured. The water wash dyed fabrics were shown the better crease recovery angles with retention of good fabric strength. Observation showed that all the property of dyed fabrics by a new method is better then the conventional method.

Keywords: Jute, Dyes, Finshing, Bleached, Mercerized,

Location: Dyeing and Finishing Department, Bangladesh Jute Research Institute

Start Date: 01-01-1993

End Date: 31-12-1993

Program Area: Postharvest and Agro-processing

Commodity: Jute

Objectives:

To study on the economic techniques of dyeing and development of suitable finishing agents for jute and jute products before and after dyeing/printing.

Methodology:

Hydrogen per oxide bleached carpet breaking were used in this experiment. A portion of the bleached fabric was mercerise. The bleached mercerised samples were dyed with reactive orange color dye separately using padding method and same percentage of dye solution by changing the sequences of conventional dyeing method. A portion of dyed mercerized sample was washed with water and other portion with an acid solution. The bleached dyed sample was then mercerized and washed with water and acid separately. All the dyed samples were dried at 105 degree Centigrade for 2 minutes. The wash fastness was measured by ISO No the crease recovery angle was measured by Good brand and Co Ltd. tensile strength machine. The rest samples were prepared for other required parameters such as moisture uptake, warmness dye absorption, fibre shredding, abrasion, softness etc. respectively.

Achievement/Findings:

It was observed that an improved and suitable wash fastness was achieved by changing the processing sequence of conventional method of dyeing. The water wash dyed fabrics were shown the better crease recovery angles with retention of good fabric strength.
