High-tenacity PET filament greige woven fabric manufacture

1. Scope and Applicability

This method covers manufacture of undyed, unsized, uncoated greige woven fabric from purchased already drawn high-tenacity continuous PET filament warp and weft yarn, through warping, drawing-in/reeding, mechanical weft insertion, inspection and rolling. The textile fibre component is exclusively PET, for subsequent industrial fabric conversion. This is a narrower representative route within CPC 26710, not coverage of the entire classification [unsd-cpc-2025]. Manufacturer originals establish commercial high-tenacity polyester greige fabric and untreated woven fabric, but do not establish that every manufacturer uses this route or omits sizing [ulong-greige]; [mehler-company-2025].

Excluded are nylon/other polyamides, viscose filament, other polymers and blends, staple yarn, strip-woven fabric, bonded cross-laid scrims, tyre cord, narrow bands, knitted fabric and nonwovens. Yarn polymerisation/spinning/drawing, on-site twisting/texturizing, sizing/desizing, washing, dyeing, printing, heat-setting, calendaring, dipping, coating and lamination are outside this authored route. The actual route must omit these operations; if present, review and extend applicability before use rather than omitting their burdens. Manufacturer distinctions between dry finishes, wet finishes and coatings show that greige cannot automatically be treated as finished fabric [mehler-company-2025].

All required qualifiers must be present in the concrete dataset. This is a mass declared unit, not functional equivalence across strengths, constructions, applications or lifetimes.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	cp_output uses a calibrated scale for matched accepted net fabric mass, excluding core, wrap and rejects, with conditioning recorded.
area_conversion	area or length statistics	Mass and area	kg; m2	Convert only with matched usable width, net length and measured mass per area: A = L × W; net mass = A × G / 1000, with L in m, W in m and G in g/m2. Catalogue nominal weight is not production output.
energy_units	electricity	Net calorific value 93a60a56-a3c8-11da-a746-0800200c9a66	kWh	Preserve public reference energy property and meter kWh; 1 kWh = 3.6 MJ; never report electricity as mass.
material_balance	yarn, fabric and wastes	Mass	kg	Reconcile issued yarn, returns, stocks, residual beam yarn, net fabric, wastes and measured releases on consistent moisture/finish basis; finish and moisture changes are not PET loss.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Purchased drawn high-tenacity PET filament packages, with required twist and supplier finish already applied, at weaving mill receipt
starting_condition_role	External yarn input, not fibre or agricultural production
product_classification_scope	Narrow high-tenacity PET greige woven subset of CPC 26710; other routes are not covered
recursive_input_rule	Internal beams and work-in-process cloth are lot transfers, not repeated purchases. External same-category fabric is recorded once with upstream linkage but requires review of the different reprocessing route
upstream_dataset_requirement	Link compatible high-tenacity filament grade/feed-state, actual electricity and packaging supply datasets; supplier yarn finish is not duplicated as mill application
disclosure	Weaving foreground is gate-to-gate; disclose geography, period, feed state, actual stages, auxiliaries, release data and unlinked upstream

rule_id	Applies to	Rule	source_ids
boundary_route	manufacture	Include receipt/warping, drawing-in/reeding, weaving, inspection, rolling, packing and attributable auxiliaries. Mechanical insertion does not cover all weaving technologies; air-jet and water-jet routes are not covered.	mehler-engineered-fabrics
boundary_finish	ending gate	Stop at untreated greige fabric; manufacturer finishing options are not compulsory operations. Actual finishing must not be hidden and requires prior method extension.	mehler-company-2025
boundary_services	utilities and releases	Include attributed climate-control and suction power and actual oil make-up/drain. If humidification water, cleaning, refrigerant leaks, packaging waste or other releases occur, add specific atomic exchanges and protocols; resource abstraction, purchased process water, wastewater and environmental release remain separate. Unmeasured status is a gap, not assumed zero.
boundary_exclusions	upstream and downstream	Resource extraction, polymerisation, filament manufacture and inbound transport lie outside this foreground. Agriculture is absent from the all-PET route. Downstream finishing, article assembly, transport, use and disposal are excluded. Disclose equipment/infrastructure exclusions and implications; do not claim complete cradle-to-gate before linking all upstream stages.

6. Process Inventory Structure

Process Map

Retain subprocess lot and measurement records. Beams, loom work-in-process and uninspected cloth are internal transfers linked by lot and mass, not additional external input. Conditional rows are included only when present; absence needs evidence and missing measurements require disclosure.

Process: Yarn receipt, warping and loom preparation (prepare)

Receive packages, verify high-tenacity certificates/feed state, warp and draw-in/reed; record net beam yarn, remnants and internal transfers. This stage does not manufacture filament or mandate twisting/sizing.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_direct	batch records	Prefer measured submetering and dedicated issue records to assign loads directly to actual batches, retaining factory evidence; do not allocate a second burden to internal beams or fabric intermediates.
allocation_shared	shared equipment	Allocate motor load using site-validated measured power integrated over runtime; shared suction/compressors use measured service demand or validated operating load, including idle load. Mass allocation requires evidence that demand is proportional to mass; retain drivers, denominators and sensitivity, with no default coefficient.
allocation_waste	returns, waste and secondary grades	Reconcile internal returns/stocks by mass. Exported waste gets no automatic recycling substitution credit. Saleable secondary-grade cloth requires actual price/quantity and co-product status; separate attributable operations first. If separation is impossible, use and disclose actual physical relationship or measured revenue with allocation sensitivity and boundary.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
normalize_batch	all inventory rows	Divide each non-reference measured net exchange by matched accepted net fabric kg from cp_output; finished output is fixed at 1 kg. Apply site-evidenced attribution first.	cp_output; cp_material; cp_energy; cp_waste; cp_air; cp_pack	exchanges per 1 kg reference flow
convert_area_records	finished_greige	Apply measured L, W, G under area_conversion for area and mass, reconcile against weighing; unverified nominal parameters cannot be used.	cp_output; area_conversion	accepted net fabric kg
reconcile_pet	warp_pet_yarn; weft_pet_yarn; prepare_pet_waste; weave_pet_waste; release_pet_waste	Reconcile net yarn issue against accepted fabric, PET wastes, actual releases and work-in-process stock change on a consistent moisture/finish basis; disclose residual and uncertainty, never invent emissions from the residual.	cp_material; cp_output; cp_waste; cp_air	mass reconciliation and residual

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
quality_identity	yarn and reference product	Both yarn systems need high-tenacity/PET evidence and actual unsized untreated start/end state; a manufacturer example does not certify this plant.	supplier certificates; order; route and acceptance
quality_coverage	all records	Disclose actual period, throughput, changeovers/idle and all foreground/auxiliary coverage; a single test does not establish an industry range.	lot, meter and production logs
quality_uncertainty	measurements and releases	Record calibration, sampling, detection limits and actual uncertainty; missing measurement, absence and differing applicability are distinct.	calibration and monitoring reports
quality_sources	public evidence	Classification supports classification boundaries and manufacturers support product/process existence only; they do not supply default recipes, energy, losses, life or environmental performance.	unsd-cpc-2025; ulong-greige; mehler-company-2025; mehler-engineered-fabrics

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_applicability	product and route	Verify all-PET high-tenacity warp/weft, unsized mechanical weaving and untreated greige endpoint. An excluded operation makes this route inapplicable; classification code cannot substitute for validation.	unsd-cpc-2025; mehler-company-2025
validate_measurement	reference and inventory	Finished reference row must be 1 kg accepted net cloth matching reference name. All rows require linked protocols and matched batch kg denominator; area needs measured conversion and electricity retains energy property.
validate_completeness	dataset	Check inputs, outputs, internal transfers, wastes, utilities and conditions by stage, disclosing real gaps; missing monitoring or unclear boundary is inconclusive, not complete validation.
validate_identity	each exchange	One substance/exchange per row; verify public material, route, geography, compartment and reference property. Disclose unresolved UUIDs rather than forcing them; a blank candidate reference is an evidence gap, not methodology approval.
