# Woven fabrics of artificial staple fibres, containing 85% or more by weight of artificial staple fibres

## 1. Scope and Applicability

This PCR applies to factory-gate production of woven fabric in which artificial staple fibres account for at least 85% of total fibre mass. Artificial staple fibres include regenerated or otherwise artificial non-synthetic staple fibres such as viscose, modal, lyocell, cupro, or acetate when the finished fabric satisfies the composition threshold. The declared fabric may be greige or may include wet pretreatment, dyeing, printing, coating, or functional finishing when those operations are part of the marketed product state and are reported explicitly.

The foreground starts with accepted spun yarn at the weaving mill and covers yarn preparation, warping, conditional sizing, weaving, inspection, and any on-site finishing needed to reach the declared factory-gate state. Upstream fibre and yarn production is represented by linked upstream datasets. Garment manufacture, distribution, use, laundering, and end-of-life are outside this PCR. Non-wovens, knitted fabrics, tufted floor coverings, special fabrics, fabrics below the 85% artificial-staple-fibre threshold, and fabrics whose dominant fibre is synthetic staple fibre are excluded.
