# Woven fabrics of man-made staple fibres, containing less than 85% of such fibres, mixed mainly or solely with wool or fine animal hair

## 1. Scope and Applicability

This PCR applies to gate-to-gate production of woven fabric whose man-made staple-fibre share is below 85% by mass and whose principal or sole blend partner is wool or fine animal hair. It covers yarn preparation, warping and conditional sizing, weaving, conditional preparation/dyeing/finishing, inspection, and packaging. The route may use synthetic staple fibres, artificial staple fibres, wool, or a named fine animal hair, but each homogeneous product route shall be modelled separately.

It excludes knitted or crocheted fabric, nonwovens, carpets, pile or special fabrics, garments, yarn sold as the reference product, fabrics whose composition belongs to another CPC leaf, and downstream use or end of life. Upstream fibre and yarn production and off-site residual treatment are represented by linked datasets unless performed inside the declared foreground site.

## 6. Process Inventory Structure

Each card below is one atomic exchange. A route shall use only the applicable cards and shall add one equally atomic card for every actual fibre, chemical, fuel, refrigerant, packaging material, waste, or emission not listed. Amounts without category-exact quantitative evidence are foreground records; this PCR defines no AI-generated amount range.
