Abstract/ Executive Summary:

The speculation of the project was that the plant of lower age would provide finer fiber with better physical and chemical properties that will enable the spinning of finer jute yarn and the value added products of jute. The fibers of the olitories variety (0-9897)of different growth ages were collected. The studies of the fibers up to 135 days age are completed.The study was mainly concentrated on the fiber yield and their physic o-chemical properties which will play the vital role in determining the value of the new fibers.The harvesting of jute plant at the age of 90-105 i.e.nearer to 90 days age appears to be optimum for obtaining fibers of expected physical and chemical properties with optimum yield with merely no cutting loss of the jute fiber for fine spinning.Accordingly measures are underway to undertake the spinning trials with fibers of 90 days age vis-a-vis the fiber of 75 and 105 days respectively.

Keywords: Jute, Fiber, Spinning, Chemical, Physical properties

Location: Pilot Plant and Processing Division, Bangladesh Jute Research Institute, Dhaka-1207.

Start Date: 01-01-1999

End Date: 31-12-2000

Program Area: Postharvest and Agro-processing

Commodity: Jute

Objectives:

To obtain ways of fine spinning of jute fiber having improved physic o-chemical properties.

Methodology:

The o-9897 variety of jute plants were cultivated in Manikganj Experimental field to produce the required fibers and accordingly fibers of ages 45,60,75,90,105,120,& 135 days were collected. ii. Plant height(PH), plant population, economic yield etc.were recorded properly. iii. Chemical composition of jute fiber were determined such as,cellulose content,Lignin content,ash, fat content. iv. physical properties (bundle strength, reed length,fineness,liner density, breaking load, etc. ) of jute fiber were determined.

Achievement/Findings:

The yield of the fibres in lower ages 45, 60, 75, are minimum (7.07-42.40) and higher in 120 and 135 days (89.33-100%). Whereas in 90 and 105 days age those are in close proximity. We prefer fibres of lower age the harvesting of 90-105 days is deemed to be appropriate.The integral major constituents i.e. cellulose content,Lignin contents are significantly the same irrespective of growth age. Hence this data do not give any indicative index of good quality fibres.The basic important physical properties of the fibres aging 45,62,77,91,104,121,and 134 days of the same variety which were been collected earlier from the same land on cultivating completely in identical conditions and are recorded. Among these properties the breaking twist and fineness parameters plays the utmost role in fine spinning. It is apparent that fibers of nearer to 90 days ages seem to be the best for fine spinning.Now the spinning trials are therefore, necessary to asses the validity of the assumption as discussed in reference to the result.It appears that the fibre yield of age 90 and 104 days are very close to the fibre yield of age 120 or 135 days aged. Moreover the cutting loss is merely nil at this age whereas for 120 to 135 days ages are much higher (6.4-8.2%).
