1. Scope and Applicability
This PCR governs factory-gate foreground data packages for cotton sewing thread made from purchased cotton yarn. The boundary begins with received yarn and includes actual on-site plying/twisting, route-gated singeing, scouring, peroxide bleaching, mercerising, package dyeing, washing/rinsing, drying/conditioning, lubrication, winding, inspection, and packaging. Cotton cultivation, ginning, fibre preparation, spinning of incoming yarn, distribution, sewing, use, and end of life are outside this gate-to-gate boundary and require linked datasets when claimed.
Conditional routes are never averaged. Each lot shall declare which operations occurred, which did not, the specific recipe chemicals and heat carriers used, and whether wastewater was sent to on-site or off-site treatment. Any vat, sulphur, pigment, specialty finish, alternative refrigerant, or alternative packaging route not represented by the atomic cards below requires additional specific cards before the dataset can claim completeness.

| How much | 1 kg net thread mass, excluding spool and transport packaging |
| How well | Meets the declared cotton composition, linear density, ply, twist, tensile/elongation grade, colour-fastness class where dyed, finish, and package specification |
| How long or cycle | One released production lot at factory gate; no use-duration equivalence is claimed |
| reference_flow_link | final_cotton_sewing_thread |
| Field | Value |
|---|---|
| Reference amount | 1 kg |
| Reference product flow | Cotton sewing thread |
| Reference flow property | Mass 93a60a56-a3c8-11da-a746-0800200b9a66 |
| Reference unit group | Units of mass 93a60a57-a4c8-11da-a746-0800200c9a66 |

4. Measurement and Unit Rules
| rule_id | Applies to | Required property | Required unit | Rule |
|---|---|---|---|---|
reference_net_mass | final_cotton_sewing_thread | Mass 93a60a56-a3c8-11da-a746-0800200b9a66 | kg | Measure conditioned net thread mass and exclude spool and transport packaging; disclose moisture/conditioning basis. |
material_mass | each material, chemical, packaging component, waste, and mass emission | Mass 93a60a56-a3c8-11da-a746-0800200b9a66 | kg | Keep every identity separate; convert formulation mass to active-substance equivalent only with a verified assay and retain both values. |
water_volume | each water and wastewater stream | Volume | m3 | Meter fresh, reused, and discharged water separately by unit operation; do not infer wastewater as equal to intake without a water balance. |
carrier_energy | electricity, natural gas, steam, and purchased hot water | Energy | kWh or MJ | Preserve each carrier separately and report conversion factors; never average mutually exclusive heat routes. |
5. System Boundary
Boundary Abstraction
| Field | Value |
|---|---|
| declared_starting_condition | Purchased cotton yarn at the thread facility, with supplier, lot, composition, yarn count, ply, twist, colour/finish state, mass, and moisture basis declared |
| starting_condition_role | Upstream product input to the gate-to-gate cotton sewing-thread dataset |
| product_classification_scope | CPC 3.0 code 26350; classification is scope evidence, not canonical identity |
| recursive_input_rule | A purchased input already sold as cotton sewing thread remains a separate upstream product flow and is not relabelled as raw cotton yarn or recursively expanded. |
| upstream_dataset_requirement | Each purchased yarn requires a compatible upstream dataset matching cotton composition, spinning route, geography, moisture basis, and market state, or an explicit data gap. |
| disclosure | Declare every on-site unit operation, route gate, heat carrier, recipe chemical, wastewater destination, emission point, waste route, and excluded upstream/downstream stage. |
| rule_id | applies_to | Rule | source_ids |
|---|---|---|---|
boundary_unit_operations | foreground gate-to-gate production | Include every actual listed unit operation and assign inputs/outputs to it; omitted operations require an explicit not-applicable justification. | csir-sewing-threads-1979; eu-textiles-bat-2022 |
boundary_route_gates | conditional routes | Do not average dyed with undyed, mercerised with non-mercerised, wax with PDMS, or alternative heat/refrigerant routes. | csir-sewing-threads-1979; eu-textiles-bat-2022 |
boundary_effluent | wet processing | Keep each unit-operation wastewater stream separate through the transfer point; direct water emissions require pollutant-specific elementary-flow cards based on monitoring. | eu-textiles-bat-2022 |
