Direct shear tester

The frictional shearing resistance at the interface between the soil and the Geotextile enables the geotextile to resist pullout failure and allows tensile forces to be carried by the soil/ geotextile composite structure.

There are two conventional laboratory tests to determine the frictional behaviour of geotextile: -

1. Test method for measuring geosynthetic pullout resistance in soil.

2. Test method for determining the co- efficient of soil and geosynthetic or geosynthetic and geosynthetic friction by direct shear method

§ Quality evaluation and grading of natural fibres using instrumental method

§ Calibration of instate developed mechanical as well as digital grading instruments

Machinery and Equipment:

Softener

Softening of raw jute streak by mechanical flexing with pressure or partial splitting of jute streak by coarse gilling.

Breaker carding machine

Splitting for filamentation as well as mixing of different grade of fibres by multiple folding of spreader sliver and sliver formation. Breaker cards are generally down striking and half circular.

Finisher carding machine

The objective of finisher card is to make the sliver regular and uniform in length and weight. The slivers also get further attenuated and equalisation of fibre takes place at the successive working zones between workers and cylinder roller.

All fibres become parallel to each other. In this operation, thinning of sliver occurs at the delivery end. This process reduces the sliver irregularity by doubling. The parts are retaining roller (to retain the fibre), drawing roller, gill comb (which has spikes to control the fibre movement, also known as gill drawing).

Yarn formation by twisting the fibre bundle on an apron draft/ slip draft flyer spinning machine and winding of yarn is done by bobbins.

Handlooms

Handlooms are characterized by their manual operation, where the weaver uses physical effort to create interlocking threads, forming the fabric. The major parts of handloom include loop frame, warp beam, heddles, shuttle and reed and the important steps in handloom weaving are warping, threading, weaving, beating and tying off.

Power Loom

A power loom is a mechanized weaving machine used for producing fabrics on a larger scale compared to handlooms. Advantages of power loom are higher productivity, cost-effectiveness, consistency, uniformity and can create complex patterns including intricate designs and patterns through dobby or jacquard shedding mechanisms.

Non-woven laboratory

Mechanical bonding

Needle punching is a widely used mechanical bonding technique in non-woven fabric production. It is a process for converting webs of fibre into coherent fabric structures, normally by means of barbed needles, which produce mechanical bonds within the web.

Thermal bonding

A blend of fusible fibre having very low melting point, with jute fibre is passed through hot calendar rollers, where fusible fibres melt and form bonds.

Adhesive bonding

The chemical bonding method is a technique used to create non-woven fabrics from jute fibers by applying chemicals that promote bonding and cohesion between the fibers.
