Grey Fabrics Testing

Grey Fabrics Testing – METS Laboratories

Grey fabrics—also known as greige fabrics—are unprocessed woven or knitted textiles straight from the loom or knitting machine. Before they undergo dyeing, printing, or finishing, it’s essential to assess their quality and structural integrity. At METS Laboratories, we specialize in comprehensive testing of grey fabrics to support textile manufacturers, processors, and buyers in ensuring consistent performance, regulatory compliance, and end-product quality.

Why Grey Fabrics Testing is Important?

Testing grey fabrics before further processing helps:
• Identify weaving defects, contamination, or fiber inconsistencies early.
• Reduce losses during dyeing and finishing due to non-conforming material.
• Ensure compliance with buyer specifications or international standards.
• Optimize fabric processing recipes based on absorbency or shrinkage.
• Improve final product quality and durability.
• Minimize environmental and operational costs in downstream processes.

What We Test?

Structural & Physical Properties:

• Thread Count (Ends & Picks per inch) – IS/ASTM
• GSM (Grams per square meter)
• Yarn Count & Ply
• Fabric Width & Length
• Construction Type (woven/knitted; plain/twill/satin)

Mechanical Properties:

• Tensile Strength & Elongation – ASTM D5035 / ISO 13934-1
• Tear Strength – ASTM D1424 / ISO 13937
• Bursting Strength (for knits)

Dimensional Characteristics:

• Shrinkage potential
• Skewness/Bowing
• Crimp ratio

Absorbency & Moisture Behavior:

• Wickability
• Moisture regain – ISO 1833

Visual and Surface Inspection:

• Fabric defects (slubs, knots, mispicks)
• Color shade variation
• Presence of foreign fibers

Optional Chemical Testing (for blends or finishes):

• pH of aqueous extract
• Presence of size, waxes, or residual chemicals
