Textile Testing

Textile Testing Sigma is a fully-fledged internationally accredited ISO / IEC 17025:2005 testing laboratory delivering broad range of textile testing services on Colorfastness, Dimensional Stability, Appearance Testing, Fabric Construction, Flammability Testing plus much more.

In the present competitive scenario consumer paid more attention on the quality of fiber, irrespective of the cost. Hence, there is need of not only stylish but also well made fibers that are free from hazardous substances.

Owing to advanced analytical instruments and experienced technicians, our facility is supposed to execute various tests related to textile industry in an efficient manner in compliance with National & International Testing Standards & Specifications.

Following are the Testing Parameters:
BREAKING LOAD:- This is the maximum force require to break the fabric in Newton
Test Method:- IS: 1969 - 2009.

ELONGATION:- The elongation test measures the percentage difference between the stretched length and the initial length of the specimen
Test Method:- IS: 1969 - 2009.

TEAR RESISTANCE:- Tear resistance is the force in Newton that is required to tear a specimen.
Test Method: IS: 6489 - 1993.

BURSTING STRENGTH:- The bursting strength is the maximum fluid pressure that is applied to a circular specimen for distending it to rupture.
Test Method: IS: 1966 - 1975.

FLAMMABILITY:- The flammability of a material is the pertinence to the relative ease of ignition the ability to sustain combustion.
Test Method: IS: 11871 - 1986.

MASS PER UNIT AREA:- The mass per unit area is defined as the mass in gram of 1 square mtr of fabric
Test Method: IS: 1964 - 2001.

THREADS COUNT:- The thread count is the number of thread in per unit length of fabric.
Test Method: IS: 1963 - 1981.

DIMENSIONAL CHANGE OF FABRIC:- The dimensional change in fabric is described as the change in dimensions of fabric when it is soaked in water under specified conditions in correspondence with the dimensions before soaking in water.
Test Method: IS: 1313 - 1984.

DIMENSIONAL CHANGE OF FABRIC (other than wool):- All the fabrics, weather woven or knitted changes their dimensions while soaked in water.
Test Method: IS: 2977 - 1989.

Test Method: IS: 1315 - 1977.

CRIMP:- CRIMP suggest the percentage difference between the yarn's straightened length and the length of yarn while in the cloth.
Test Method: IS: 3442 - 1980.

TWIST:- The twist is defined as the number of turns around the axis of yarn based on its nominal gauge length before untwisting. It is expressed as the turn per meter.
Test Method: IS: 832 - 2011.

COLOUR FASTNESS:- The color fastness is measured as change in color in the treated fabric in compare to original fabric.

Type of Colour Fastness
Test Method: IS: 762 - 1988.

IDENTIFICATION OF FIBRES:- The behavior of textile is predicted by fiber identification under different environmental conditions.
Test Method: IS: 667 - 1981.

BLEND COMPOSITION:- The blend composition is carried out to find the amount of fibers in one 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:- These are tested for having deleterious effects on the fibrous material.
Test Method: IS: 4202 - 1967 for Chloride and IS: 4203 - 1967 for Sulphate.

FATTY MATTER CONTENT:- The fatty matter content is the dried solvent residue content.
Test Method: IS: 199 - 1989.

MOISTURE CONTENT:- The moisture content is expressed as the loss in weight, when fabric is dried at 105 degree celsius.
Test method: IS: 199 - 1989.

ASH CONTENT:- The ash content is the residue, which is left from the ignited fabric under prescribed conditions.
IRON & CHROMIUM:- Iron and Chromium present in the fabric indicate the amount of mineral khaki present in the fabric.
Test Method: IS: 4655 – 1968.

SOLVENT SOLUBLE MATTER:- The solvent soluble matter is the known amount of ethyl ether or benzene methanol mixture. These dried and left over residue is expressed in terms of weight percentage of textile material.
Test Method: 4390 - 2001.

pH VALUE OF WATER EXTRACT:- The pH value of the water extract refers to the processing history of the textile index. This conforms to certain limits including its acidity or alkalinity.
Test Method: IS: 1390 - 1983.

SCOURING LOSS:- The scouring loss refers to the loss of natural impurities such as pectin, oil, fats and waxes. These are gathered while fabric is undergoing various treatments.
Test Method: IS: 1383 - 1977.

CARBOXYLIC ACID GROUP IN CELLULOSIC TEXTILE MATERIAL:-The cellulose in the form of fibers comes in contact with various oxidizing agents while undergoing different chemical treatments. The result is the formation of acidic oxy cellulose.
Test Method: IS: 1560 - 1974.

BARIUM ACTIVITY NUMBER:- The barium activity number is the ratio in which barium hydroxide is absorbed by mercerized cotton to that of unmercerized cotton under certain conditions. The ratio is then multiplied by 100.
Test Method: IS: 1689 - 1973.

Formaldehyde in Textiles Formaldehyde is released by the textiles with some special finishes, when new, such as crease resistance. These are mostly used on cotton or woolen textiles. It is water soluble and released from the fabric, when fabric is washed before wearing.
Test Method: IS: 14563 - 1999.


We also provide testing for zips used in various dresses like luggage, knit wears, leather garments, skirts, foot-wears, jeans, sleeping bags and many more.

Following tests are performed on zippers as per BS: 3084:
