FABRIC CHEMICAL TESTING

 The fabric manufactures, used the most of chemicals for scoring, bleaching, dyeing & printing process. therefore, these chemicals effect for human body, quality of the garments and their end uses. By testing of the chemical's harmfulness & effectiveness of the quality is important to satisfaction of customer.

Whether for safety, performance, or compliance, chemical testing ensures that textiles meet quality and environmental standards across the supply chain. Accuracy of the test reports & reliability are maintained by the worldwide recognized organizations

Standard Testing Organizations

• ISO (International Organization for Standardization)
• ASTM (American Society for Testing and Materials)
• AATCC (American Association of Textile Chemists and Colorists)

    Each provides standardized procedures to ensure repeatable and reliable results across the textile            industry.

FABRIC CHEMICAL TESTS

Color Fastness to Washing

Determines how well a dyed fabric retains its color after laundering & asses the reading with grayscale ratings. 

useful to reduce the color bleeding, fade of the garments

ISO 105-C06 color fastness to washing

Color Fastness to Rubbing

Tests how much dye rubs off onto other surfaces (dry or wet). 

When reducing number of washing during the cycles dyeing process, extra dyes on the surface of fabric. 

Mainly request for dark or bright garments like jeans or scarves.

ISO 105-X12 Color Fastness to Rubbing

Color Fastness to Light

Measures how resistant the fabric color is to fade when exposed to artificial light.

Request for curtains, upholstery, and outdoor textiles.

ISO 105-B02 Color Fastness to Light

pH Value 

pH level should be maintained for the optimal level for human body condition. When it is varied, harmful for human skins & Asthma.

pH values outside the neutral range (4–7) can cause skin irritation. 

ISO 3071 

Formaldehyde Content

Detects residual formaldehyde from wrinkle-free or anti-shrink finishes.

High levels can cause allergic reactions or respiratory problems.

ISO 14184-1

Azo Dyes Test

Checks for banned aromatic amines released from azo dyes.

Need theses compliance details for accept the production from the fabrics- EU, REACH, and OEKO-TEX® certifications.

ISO 14362-1

Heavy Metal Tests

Measures toxic metals like lead, cadmium, mercury, and chromium in fabric.

Ensures safety, especially in children’s clothing and baby products.

ISO 17072 or EN 16711

Flame Retardancy Test

Assesses how fabric behaves when exposed to open flame.

Protective gear, home furnishings, public space textiles.

ISO 15025 (Protective clothing) & ISO 6940/6941 (Vertical/horizontal flame spread)
