Tulles and Other Net Fabrics, Except Woven, Knitted or Crocheted Fabrics; Lace in the Piece, in Strips or in Motifs

1. Scope and Applicability

This PCR applies to the factory-gate production of tulle and other open net fabrics made by non-woven, non-knitted and non-crocheted thread-interlacing routes, and to lace supplied in the piece, in strips or in motifs. It covers bobbinet or comparable twisted-thread net formation, bobbin lace and other lace routes within the CPC 27912 semantic boundary, including route-applicable preparation, wet processing, finishing, inspection, trimming and packaging. The declared dataset starts with purchased yarn or thread at the reporting-facility gate and ends with saleable packed product at that gate.

Woven gauze or mesh scrim, knitted or crocheted net and lace, embroidery classified separately, narrow woven trimmings, knotted netting or made-up nets, nonwovens, coated or impregnated fabrics classified elsewhere, and made-up apparel or articles are excluded. A foreground package shall identify one concrete production route and shall not combine materially different fibre systems, formation technologies, finishing routes or sites unless the aggregation is disclosed and satisfies this PCR's allocation and quality rules. The CPC scope is supported by unsd-cpc-3-0-2025; fibre identity and composition disclosure are supported by eu-textile-fibre-regulation-1007-2011 and iso-1833-1-2020.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	accepted saleable reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Determine net product mass after the declared conditioning procedure; exclude pallets, cartons, cores and wrapping from the 1 kg reference amount. Record gross, tare and net mass evidence.
conditioning_basis	product, yarn and offcut mass measurements	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Condition specimens or lots under ISO 139 or a declared contractually equivalent atmosphere before using measured mass for product qualification or mass-balance validation; disclose any alternative atmosphere.
area_length_conversion	records collected in m2 or linear m	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Convert area or length records to mass only with lot-specific measured mass per unit area or mass per unit length and declared width; do not substitute a generic fabric factor.

5. System Boundary

The foreground boundary includes receipt and internal handling of yarn, thread, chemicals and packaging; bobbin winding or equivalent route-specific preparation; non-woven/non-knitted/non-crocheted net or lace formation; route-applicable washing, scouring, bleaching, dyeing, rinsing, drying, heat-setting or chemical finishing; inspection, mending where performed, trimming, packing; on-site utilities; internal material handling; direct emissions; and on-site waste and wastewater handling. Upstream production of purchased yarn, chemicals, energy, water and packaging is represented by upstream datasets. Capital goods, employee travel, product use and downstream end-of-life are outside this factory-gate dataset unless the study goal explicitly extends the boundary.

Boundary Abstraction

Field	Value
declared_starting_condition	Purchased yarn or thread lots, purchased auxiliaries and packaging are received at the reporting-facility gate with supplier identity, quantity, fibre/composition specification and upstream dataset reference.
starting_condition_role	The received yarn or thread is the first foreground-controlled material state; upstream fibre, polymer, spinning, filament and transport burdens remain represented by linked upstream datasets.
product_classification_scope	Only products satisfying the CPC 27912 boundary are reference products; woven, knitted, crocheted, embroidered, knotted-net, made-up-article and separately classified coated-fabric outputs are excluded.
recursive_input_rule	A purchased CPC 27912 input used in another CPC 27912 product shall be recorded once as an upstream product input with its supplier dataset; its manufacture shall not be recursively reconstructed inside this foreground dataset.
upstream_dataset_requirement	Each purchased yarn/thread, chemical, energy carrier, water supply and packaging input requires a geographically and technologically representative upstream dataset or an explicit documented data gap.
disclosure	Declare fibre composition, formation route, wet-processing and finishing applicability, outsourced operations, site, period, allocation basis, rejected output, wastewater route, packaging state and all excluded operations.

rule_id	Applies to	Rule	source_ids
boundary_factory_gate	all foreground packages	Include all on-site operations from receipt of yarn/thread through packed saleable product and all associated direct wastes and emissions; identify outsourced operations and link their datasets rather than silently excluding them.	ec-jrc-textiles-bref-2023; eu-pef-2021-2279
boundary_route_specificity	formation, wet processing and finishing	Mark each route-applicable operation as included or demonstrably not applicable; absence requires product and process evidence, not a zero inserted without explanation.	irvine-ruskey-bobbin-lace-2014; ec-jrc-textiles-bref-2023
boundary_no_recursive_rebuild	purchased CPC 27912 intermediates	Stop foreground tracing at the declared supplier product and require an upstream dataset, preventing double counting of the same manufacturing steps.	eu-pef-2021-2279

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
integrated_net_lace_manufacturing	Integrated tulle, net-fabric or lace manufacturing	required	Always; operation-level applicability for preparation, formation, wet processing, finishing and packing must be declared	Foreground production from purchased yarn/thread to packed factory-gate CPC 27912 product	1 kg accepted conditioned net product output

Process: Integrated tulle, net-fabric or lace manufacturing (integrated_net_lace_manufacturing)

This process is an aggregated foreground unit process. Its operation ledger shall separately identify yarn/thread preparation, bobbinet or other non-woven/non-knitted/non-crocheted formation, any wet processing, drying/setting/finishing, inspection/trimming and packaging. Bobbin-lace formation by braided threads is supported by irvine-ruskey-bobbin-lace-2014; cross-cutting preparation, pretreatment, dyeing and finishing operations are supported by ec-jrc-textiles-bref-2023.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_avoid	shared production and utilities	Prefer submetering, batch records and physically separated inventories so allocation is avoided. Do not allocate avoidable material losses or rework away from the lot that caused them.	eu-pef-2021-2279
allocation_physical	shared equipment or meters serving multiple products	When separation is not feasible, allocate electricity, fuel, steam, water and common consumables using the measured causal driver: machine-hours adjusted by measured load, bath volume, dryer throughput or conditioned product mass, in that order of relevance. Record the denominator and coverage.	eu-pef-2021-2279
allocation_economic_exception	multiple valuable outputs lacking a defensible physical relationship	Use economic allocation only after documenting why subdivision and physical causality fail; use contemporaneous factory-gate values, disclose price period and currency, and test sensitivity.	eu-pef-2021-2279
allocation_rework	internal rework	Keep the original material and energy burdens in the reporting lot; record only additional rework inputs and do not count the same intermediate mass as a co-product.	eu-pef-2021-2279
allocation_waste_recovery	offcuts, rejects, sludge and packaging waste	Report waste mass and destination separately. Apply the selected study's documented waste/recycling method consistently; do not credit recovery without a named downstream dataset and explicit burden/benefit boundary.	eu-pef-2021-2279
