FOREWORD

This Indian Standard (First Revision) was adopted by the Bureau of Indian Standard, after the draft finalized byChemical Methods of Test Sectional Committee had been approved by Textile Division Council.

This Indian Standard was first published in 1967 and has been revised to accommodate use of benzyl alcohol assolvent for waluating solvent soluble matter in cotton textiles presently covered in IS 5152 : 1969. As a resultof above 1S 5152 : 1969 stands withdrawn.

There is no International standard on the subject,

The composition of the Committee responsible for formulation of this standard is given in Annex A.

In reporting the result of a test made in accordance with this standard, if the final value, observed or calculated,is to be rounded off, it shall be done in accordance with IS 2: 1960 ‘Rules for rounding off numerical values(revised)’.

TEXTILES — METHOD FOR ESTIMATION OFSOLVENT SOLUBLE MATTER IN

TEXTILE MATERIAL(First Revision)

1 SCOPE

This standard prescribes a method for determinationof solvent soluble matter in textile materials usingbenzene-methyl alcohol mixture or ethyl ether assoIvent.

2 REFERENCES

The Indian Standards given below contain provisionswhich through reference in this text, constituteprovisions of this standard. At the time of publication,the editions indicated were valid. All standards aresubject to revision and parties to agreements based onthis standard are encouraged to investigate thepossibility of applying the most recentstandard given below:

3 PRINCIPLE

A known amount of test sample is extracted withbenzene-methyl alcohol mixture or ethyl ether assolvent. The solvent is dried and the residue isexpressed as the percentage of the weight of theconditioned textile material.

4 SAMPLING

4.1 Sampling for Fibre and Yarn

4.1.1 Lot

The quantity of tibre or yarn from the same sourceshall constitute a lot. If the lot contains more than200 kg of fibre or yarn, it shall be divided in sub-lots,each weighing 200 kg or less.

4.1.2 From the sub-lot 15, increments eachapproximately weighing 10 g shall be taken fromdifferent parts so that a representative sample isobtained. All the increments, thus, collected shall bethoroughly mixed to get the test sample.

4.2 Sampling of Fabrics

4.2.1 Lot

The quantity of fabric manufactured under relativelyuniform conditions shall constitute a lot.

4.2.2 The number of pieces to be selected from a lotshall be as given below. The pieces selected shallconstitute the gross sample:

Lot Size Sample Size

upto 100 3

lolto 300 4

301 to 500 5

501 and above 7

4.2.3 From each piece in the gross sample about 25 gof fabric shall be taken out from at least two differentparts. The parts shall be then cut into further smallerpieces and thoroughly mixed. The pieces thus collectedshall constitute a test sample.

5 PREPARATION OF TEST SPECIMENS

Cut the test sample into small pieces, Mix all the piecesthoroughly. Draw at least three test specimens fromamong these pieces such that each specimen weighsabout 5 g.

6 CONDITIONING OF TEST SPECIMENS

Prior to test, the test specimens shall be conditionedfor 24 hours for moisture equilibrium in a standardatmosphere at 65 + 5 percent relative humidity and27°+20C temperature (see also IS 196).

7 APPARATUS

7.1 Soxhiet Apparatus

7.2 Reflux Condenser

8 REAGENTS

8.1 Quality of Reagents

Unless specified otherwise, pure chemicals shall beemployed for tests and distilled water (see IS 1070)shall be used where the use of water or distilled wateras reagent is intended.

1

Is 4390:2001

NOTE —” Pure chemicals’ shall mean chemicals that do not con-tain impurities which affect the test results.

8.2 Benzene-Methyl Alcohol Mixture

Prepared by mixing three volumes of benzene (see 1S1840) with two volumes of methyl alcohol (see1S517).

8.3 Ethyl Ether

Redistilled (see IS 336).

9 PROCEDURE

9.1 Condition the test specimens to moistureequilibrium in standard atmosphere (see 6). Weigheach test specimen accurately.

9.2 Take one test specimen and put it in thimble ofSoxh let apparatus (see Note). Extract the specimenwith 150 ml of benzene methyl alcohol mixture orethyl ether in a Soxhlet apparatus for 3 hourssiphoning the solvent at a minimum rate of 10extractions per hour.

NOTE — I~the thimble isnot available, tbe test specimen should

be wmppcd in filter paper.

9.3 Reduce the extract, if necessary, by subsequentdistillation to a volume of approximately 25 ml. Filterthe extract through a rapid filter paper and collect theextract in a 50 ml tared flask. Wash the filter paperand the extraction flask with small portions of solvent

and add the washings to the extract.

9.4 Evaporate the extract in the tared flask. Dry theresidue to constant weight at 105 to 11O°Cand weigh.

9.5 Calculations

Calculate the percentage of solvent-soluble matterpresent in the textile material by the following formula:

p=txloou

where

P = percent, by weight, solvent-solublematter in the test specimens;

b = Weight, in g, of the residue (see 9.4); and

a = conditioned weight, in g, of the testspecimen (see 9.1).

9.6 Repeat the test with the remaining test specimensand calculate the solvent-soluble matter in each testspecimen.

9.7 Calculate the average of the values obtained asin 9.5 and 9.6.

10 REPORT

Report the value obtained in 9.7 and the solvent used.
