7 IS : Indian Standard GRADING OF UNCUT INDIAN MESTA 0. FOREWORD 0.1 This Indian Standard was adopted by the Indian Standards Institution on 15 July 1981, after the draft finalized by the Jute and Jute Products Sectional Committee had been approved by the Textile Division Council. 0.2 Grading of white, TOSSA and DAISEE uncut Indian jute has been covered in IS : * which now forms the established basis of grading of raw jute. Formulating of similar grading standard for MESTA fibres has been taken up on the request from different interests. In this standard, 6 grades have been prescribed for MESTA. A scoring system has been included to grade the fibres on the basis of strength, defects, root contents, colour and fineness. 0.3 A separate Indian Standard for grading of RIMLI is being processed. 1. SCOPE 1.1 This standard covers grading of MESTA fibres from which the roots have not been cut. 2. TERMINOLOGY 2.0 For the purpose of this standard, the following definitions shall apply. 2.1 MESTA - It is a substitute for jute obtained from the bark of Hibiscus Cunnabinus, it is generally inferior and coarser than jute. Chemically the fibre is different from jute in its low lignin content. 2.2 Parcel - A consignment containing certain number of bales, bundles or drums. 2.3 Strength -- The ability of the fibres to resist strain or rupture induced by external forces. * Grading of white, TOSSA and DAISEE uncut lndian jute ( wand rcuism ), 3

8 IS : The strength aspect of the fibres is classified depending upon their tenacity. The terms used for the purpose of grading are Very good, Good, Fairly good, Average and Weak mixed. NOTE 1 -Tenacity is the breaking load of a material under test divided by the linear density of the unstrained material, expressed as grams per tex. NOTE 2 - Linear density is the mass per unit length; the quotient obtained by dividing the mass of fibre or yarn by its length. When the mass is expressed in grams and the length in kilometres, the resulting value, that is, the quotient, is expressed as trx. 2.4 Colour - The property of a fibre which distinguishes its appearance as creamy, white, grey, etc The colour description of fibres in relation to the terms used for the purpose of grading is given below: Good Creamy to whitish Fair average Light grey Average Greyish to dark 2.5 Fineness - A measure of diameter ( width ) or both, of the fibrc filament. ( The finer the fibre, quality. ) or mass per unit length, the better is its spinning The fineness aspect of the fibrc is classified depending upon its tex value ( see Note 2 under ). 2.6 Reed -~~ The fibre system front the individual MESTA plant. 2.7 Reed Length --- The length of the reed from bottom to top. 2.8 Effective Reed Length-The length of the reed after the root and hard barky crappy ends have been removed. 2.9 Root-The hard barky region at the lower end of the reed which requires additional softening treatment, normally called cuttings Centre Root ( BUKCHHAL 1 -- The hard barky region in the middle part of the reed which requires additional softening treatment Dazed Fibre -- Fibrc which is weak in strength and dull in appearance, due to usually being stored in moist condition Over-Retted Fibre ~~~ Fibre which has lost its strength and brightness due to prolonged retting Runners ~ Hard barky tibre running from the lower end to the middle region, more or less continuously. 4

9 IS : 9S Knots - Stiff barky spots in the body of the reed which break the continuity of the fibres when opened Mossy Fibre - A type of vegetation which sometimes gets attached to the MESTA plant Its portions may remain on the fibre even after retting and washing. It can be separated by hand Sticks Entangled Sticks, and Loose Sticks - Sticks are remnants ofwoody part of MSTA plant over which fibre sheath is formed. Entangled sticks are broken sticks which are linked with fibre mass and are not easily removable. Loose sticks are broken sticks easily removable by shaking Croppy Fibre - Fibre with top ends rough and hard ( but not barky ) caused by careless retting Weak Croppy Fibre - Fibre which has become unusually weak over a length of about 30 cm at the top end Entangled Croppy End Fibre -- Fibre with unusually entangled crappy end Gummy Fibre - Fibres held together by undissolved pectinous matter Leaf, and Loose Leaf - Leaf is the dark grey leafy or paper like substance ( remnant of the skin of the plant ) appearing on the strand. Loose leaves are those that lie loosely on the fibre and are easily removable Specks -~ Soft barky spots in the body where fibres can be separated with some ellort without breaking their continuity, though they may remain as weak spots Hunka - The very hard barky fibre running continuously from the lower end to almost the tip of the reed Natural Dust - The dust which might get associated with the fibre during the process of its production Defects Major - Entangled crappy end, fibre, centre root, dazed and over-retted fibres, runners, knots and entangled sticks Minor ~~ Croppy fibre, weak crappy fibre, gummy fibre, loose sticks, specks and mossy fibres. 5

10 IS : UNIT OF GUARANTEE 3.1 The unit of guarantee shall be a bale, bundle or drum made ofmorahs or heads. For purposes of appraisement, each such bale, bundle or drum shall be treated as a separate unit and shall, in itself, fulfil thr guarantee of the grade. 4. GRADING 4.1 The MESTA fibre ( from which roots have not been cut ) shall be classified into 6 grades as given in Table The hand and eye method may be used in assessing these qualities as is presently in vogue in the trade but in the case of dispute, the corresponding test method applicable for jute as mentioned in lhc table may also be followed for correct assessment on scientific basis. NOTE -According to the trade practice for comparing strength, the tufts of fibres of approximately equal size held equal distance apart, are broken longitudinally without jerk. Good lustre indicates good fibre strength. Root contcnl in terms of percentage by mass isjudged by observing the extent ofroots along the length. Light or heavy bodiedness of the fibre is asscsscd by feeling the lightness or heaviness of a bunch of fibre reeds ( by raising and lowering) when held within a grip. 4.3 Relative weightage to each of the quality characteristics is attributed by a system of scoring for various grades by the hand and eye method for routine grading. The marks allocated are on the basis of the objective assessment of the different quality characteristics and as such shall Ix used for the purpose of grading on the basis as given in Table PACKING 5.1 The MESTA fibre should be so packed that MORAHS in any one bale, bundle or drum are of only one grade. 5.2 Each bale, bundle or drum should have a grade tag indicating the year of harvest, grade and trade-mark. 6

When the score is less by 50 ( or more ) percent of the difference, the buyer will have option to reject or settle with a suitable discount. g) Scores in the table may be taken as guidance for determining the discount. * Physical method of test for white, TOSSA and DAISEE uncut Indian jute : Part II Reed length.
