Apparent Opening Size (AOS) |
The AOS, or equivalent opening size (EOS) are defined in CW-02215 as the U.S. stand number that has
openings closet in size to the openings in the geo-textiles. |
Areal Density |
It is the weight of fabric per unit area. |
Assortment |
It is the selection and classification of raw jute according to fabric characteristics prior or baling.
|
Bag – A Twill |
A double warp hemmed twill bag of 112 x 76.5 cm. Size and weighing 1190 gm with strips woven along the
length of the bag and used for packing sugar. |
Bag – B Twill |
A double warp hemmed twill sacking bag measuring 112 x 76.5 cm. And weighing 1020 the capacity of
holding 95 kg of food grains. With three blue stripes woven along the bag and is used for packing food grain. Due to IOL stipulation, a new type of B.T. has been developed with 50 kg capacity, dimensions 94
x 57 cm, and bag weight of 665. |
Bale ( Kutcha ) |
A package of raw jute consists of various morahs, weighing 130 kg. to 150 kg. Sometimes only 55 kg. It is
bound with jute ropes. |
Bale ( Pucca ) |
It is hydraulically pressed bale of raw jute usually bound with jute ropes. Its standard (120 x 45 x 50 )
cm having net weight of 180 kg. |
Bale ( Fabric or Jute Bags ) |
A rectangular or square pressed, rigid package, containing jute fabrics or bags, covered covering
with quarter layer stitched and bounded by metal hoops in conformity with the specifications. The bales containing jute bagging do not have covering. |
Batch |
A quality of raw jute selected from various assortments to produce yarn of desired type quality. |
Batching |
It is a process of selecting and mixing of jute fibers into batches and treating them with oil-in-water
emulsion softening the fibre prior to carding operation. |
BJRI |
Bangladesh Jute Research Institute, Dhaka, Bangladesh. |
Biocomposites |
Composites which are biodegradable, composed of natural fibre reinforcement embedded in bio-polymeric
matrix. |
Braiding |
The process of interlacing three or more threads is made in such a way that they course of other and are
laid together in a diagonal formation. Flat tubular, or solid constructions be formed together in this way. |
Doubling |
A process in which a number of jute silvers fed simultaneously as input into a machine for drafting and
delivered as a single silvers output. By this process, the irregularity of input silvers gets reduced. |
Draft |
The amount of attenuation of textile material at different stages of spinning preparatory and spinning
process, for example. 1 m of input material when delivered as 5 m is said to have undergone a draft of 5. |
Drafting |
It is a process of reducing the bulk and weight per unit length of silver and simultaneously parallelising
its fibrous components, as it passes through the various machines used in making yarn. |
Drawing / Gilling |
An operation, preparatory to spinning, of passing jute fibres through one or more gill boxes in order to
attenuate the card silvers and to improve fibre parallelisation. |
Dressing |
A process of treating jute wrap yarn with size prior to weaving. |
Elongation at Break |
It is the extension, expressed in % of fibre or yarn specimen at break |
Emulsion |
Dispersion of oil in water in presence of an emulsifier is known as emulsion. Three main ingredients of an
emulsion are oil (JBO or alternative lubricant like RBO), water and emulsifier. These ingredients are applied together for softening and lubrication of fibres and applied on jute fibre prior to its mechanicals
processing. While the oil component helps to reduce the fibre metal friction and to produce the moisture evaporation ever time, the water helps to reduce the fibre rigidities, flexural and torsional. |
Ends |
The threads which lie along the length of a woven fabric. |
Evenness |
The uniformity of any textile material in terms of thickness or diameter or weight per unit length. |
Filtration |
Passing the water along and across the plane of geo-textile. |
Flexural Modules |
It is the ratio of maximum stress to strain within elastic limit in case of flexural deformation. |
Flexural Strength or MOR |
The maximum stress (load / area) just before it cracks or breaks in a flexural test.
|
Geo-textile |
These textile materials are used by civil engineers to solve many geo-technical problem. These materials
are made of synthetics or natural fibres in the form of woven or non-woven or their combination. |
Grading of Jute |
Jute fibre quality is classified into different grades depending on a 'hand-and-eye' assessment of its
strength, root content, colour, fineness and bulk density yarn / fabric quality, a particular grade or a combination of two / three grades of fibres is used for ensuring the product quality as well as the productivity.
|
Grist |
Grist (basically, linear density), expressed as lb of jute yarns is the weight in lb of yarn length. It is
the most commonly need term for expressing the coarseness or jute yarn. |
Hank |
A yarn or twine of a particular length in coiled form |
Hard Twisted Yarn |
Yarn having more twist than normal. |
Hard Waste |
Yarn wastes produced during spinning, preparatory and weaving process. |
Hessian |
A single wrap plain weave jute fabeic being manufactured in various widths and weigh up to a maximum of 500
g/m. |
IJIRA |
Indian Jute Industries' Research Association, Kolkata, India. |
IJT |
Institute of Jute Technology, Kolkata, India. |
Impact |
It is the resistance to fracture when certain localized load in applied to the specimen two types. Notched
and Un-notched. |
Initial Re-inforcement |
The synergistic improvement of a total system's strength created by the introduction geotextile (good in
tension) into a soil (in compression but poor in tension) or into of and separated material. |
