COLOUR FASTNESS:- The fastness is assessed by comparing the change in colour of a treated specimen to the original sample of the fabric.
Test Method: IS: 686 – 1985 & IS: 2454 – 1967.
Test Method: IS/ISO: 105 – C 10: 2006.
Test Method: 688 – 1988.
Test Method: IS 971 – 1983.
Test Method: IS 762 – 1988.
Test Method: IS 667 – 1981.
BLEND COMPOSITION:- To find out the number of different fibres in the sample.
Test Method: IS: 1564-1988, IS: 1889-1976, IS: 2005-198, IS: 2006-1988, IS: 3416 -1999; IS: 3421-1988; IS: 6503-1988; IS:6504-1988; IS: 9896-1981.
CHLORIDE AND SULPHATE:- In textile industries, textile material undergoes various treatments in course of which, an extraneous matter of various type as sizing or finish material water-soluble salt (chlorides & sulphates) is gathered by or added to textile materials. Such water-soluble substances, if present in more than certain quantities, may have deleterious effects on the fibrous material.
Test Method IS: 4202 – 1967 for Chloride and IS 4203 – 1967 for Sulphate.
FATTY MATTER CONTENT:-The sample is extracted with the solvent, which is dried and the residue is expressed as fatty matter.
Test Method: IS 199 – 1989.
MOISTURE CONTENT:- When the sample of textile in any form such as yarn, fibre and fabric dried at 105°C, the loss in weight is expressed as the moisture content of the sample.
ASH CONTENT:- When the textile in any form such as yarn, fibre and fabric (which is dried previously) is ignited under prescribed conditions, then the residue left is expressed as the Ash content of the specimen.
IRON & CHROMIUM:- Iron and Chromium are present in large quantities in textile; dyed in mineral Khaki; mineral khaki dyed material is used mainly for defence and civilians as well for making uniforms. The Iron & Chromium content of the fabric would give an indication regarding the amount of mineral khaki present in the textile material.
Test Method: IS 4655 – 1968.
SOLVENT SOLUBLE MATTER:- A known amount of specimen extract with ethyl ether or benzene methanol mixture as a solvent. A solvent is dried and the residue is expressed as the percentage of the weight of the textile material.
Test Method: IS:4390 – 2001.
pH VALUE OF WATER EXTRACT:- The pH of the aqueous extract of the textile affords a useful index to its processing history. In addition, it is becoming more common to demand that the textile in its various forms, shall conform to certain limits in respect of its acidity or alkalinity, often expressed in terms of pH values of aqueous extracts.
Test Method: IS 1390 – 1983.
SCOURING LOSS:- In the cotton textile industries, yarn and fabrics undergo treatments in the course of which extraneous matter of various types is gathered by or added to the original material, which if not scoured or partly scoured may also contain natural impurities such as oil, fats, waxes and pectins.
Test Method: IS 1383 – 1977.
CARBOXYLIC ACID GROUP IN CELLULOSIC TEXTILE MATERIAL:- In the cellulosic textile industries, cellulose in the form of fibres, yarn and fabric comes in contact with different oxidizing agents during the various chemical processing treatments. The action of these oxidizing agents on cellulose may result in the formation of oxy cellulose of acidic character, attributable to the introduction of the carboxyl group into the cellulose chain molecule.
Test Method: IS 1560 – 1974.
BARIUM ACTIVITY NUMBER:- The ratio of the quantity of barium hydroxide absorbed by mercerized cotton to that absorbed by un mercerized cotton under identical conditions multiply by 100.
Test Method: IS 1689 – 1973.
Formaldehyde in Textiles Formaldehyde is released by some textile finishes, such as those conferring crease-resistance, while the garment is new. These finishes are most likely to be used on fabrics that otherwise crease easily, such as cotton or wool. Formaldehyde is very water-soluble, and washing the new garments before wearing will generally reduce the amount of formaldehyde released from the fabric.
Test Method: IS 14563 – 1999.
