# Woven pile fabrics and chenille fabrics (other than terry towelling and narrow fabrics) of man-made fibres

## 1. Scope and Applicability

This PCR applies to woven pile fabrics and chenille fabrics made from man-made fibres and delivered as finished manufactured fabric at the mill gate. It covers pile formation or chenille weaving, route-specific wet processing, physical or chemical finishing, inspection, and packing when those operations are controlled by the reporting site.

The category excludes terry towelling, narrow fabrics, cotton-only products, nonwoven fabrics, knitted pile fabrics, carpets, apparel, and production of man-made polymers, fibres, or yarns. A fabric containing natural-fibre blends remains in scope only when its declared product classification and commercial identity remain CPC 26820; composition and blend fractions must be disclosed.

No generic textile UUID may replace the exact category reference flow. The public CPC 26820 product-flow identity is used only after hybrid retrieval and direct Tiangong readback confirmed its name, classification, Product flow type, public state, and Mass reference property.
