Woven fabrics of cotton, containing 85% or more by weight of cotton, weighing not more than 200 g/m2

1. Scope and Applicability

This PCR defines foreground data for greige, plain or other ordinary woven cotton fabric at the weaving gate. The accepted fabric contains at least 85% cotton by dry fibre mass and has an areal mass at or below 200 g/m2. Record actual weave, yarn and sizing route. Wet preparation, bleaching, dyeing, printing and finishing require a separate declared downstream dataset and are outside this greige gate. This narrower production state must not be represented as all finished products in CPC 26610.
