Textile Testing Services

In today’s highly competitive global market, consumers and regulatory bodies place significant emphasis on the quality, safety, and performance of textile materials rather than only their cost. Modern textiles are expected not only to be aesthetically appealing but also durable, reliable, and free from hazardous substances.

Sigma Test & Research Centre (STRC) offers comprehensive Textile Testing Services supported by a fully equipped in-house laboratory. Our textile testing facility is equipped with advanced analytical instruments and operated by experienced laboratory professionals who ensure precise and reliable test results.

All testing services are conducted in strict accordance with relevant Indian Standards (IS), ISO standards, and international testing protocols. We provide accurate, dependable, and meaningful testing for yarns, fabrics, garments, carpets, non-woven textiles, medical textiles, and other textile products.

Crimp – IS 3442:1980

Crimp represents the difference between the straightened yarn length and its length in the fabric, expressed as a percentage.

Twist – IS 832:2011

Twist refers to the number of turns per meter (TPM) in yarn, which affects strength, elasticity, and durability.

Colour Fastness Testing

Colour fastness evaluates the resistance of dyed textiles to fading or bleeding when exposed to different environmental conditions.

Colour Fastness to Organic Solvents – IS 688:1988

Assesses colour stability when exposed to dry-cleaning solvents.

Colour Fastness to Perspiration – IS 971:1983

Determines colour resistance when fabrics come in contact with acidic or alkaline perspiration solutions.

Colour Fastness to Bleaching – IS 762:1988

Evaluates the resistance of textile colour when exposed to bleaching agents such as sodium hypochlorite and hydrogen peroxide.

Chemical Testing of Textiles

Fibre Identification – IS 667:1981

Determines the type of fibre present in textile materials, which helps predict performance and processing behaviour.

Blend Composition

Used to determine the percentage composition of different fibres in blended textile materials.

Chloride & Sulphate Content

IS 4202:1967 (Chloride)
IS 4203:1967 (Sulphate)
Determines the presence of water-soluble salts that may affect fibre durability and processing quality.

Fatty Matter Content – IS 199:1989

Determines the amount of fatty substances present in textile materials.

Moisture Content

Measures the percentage loss in weight when textile samples are dried at 105°C.

Ash Content

Determines the residual inorganic matter remaining after combustion of textile materials.

Iron & Chromium – IS 4655:1968

Used particularly in mineral khaki dyed fabrics to determine the presence of iron and chromium compounds.

Solvent Soluble Matter – IS 4390:2001

Determines the percentage of substances extractable with organic solvents.

pH Value of Water Extract – IS 1390:1983

Evaluates the acidity or alkalinity of textile materials, which indicates processing conditions.

Scouring Loss – IS 1383:1977
