Waterborne PU direct-coated woven polyester fabric

1. Scope and Applicability

This manufacturing profile covers dry roll fabric with a woven continuous-filament PET substrate and one directly applied, unpigmented, non-foamed aqueous aliphatic polyester-PU coating, made from a purchased ready-formulated dispersion, optionally diluted with process water, electrically dried and cooled. The starting fabric is coating-ready, with its previous wet processing completed. Representative product: a declared grade of coated roll fabric for subsequent bag manufacture; this is a production reference, not a guarantee of waterproofness, safety or service life.

The official CPC 3.0 note lists27997 without a detailed process explanation. Classification context does not establish applicability. Solvent-based PU, wet coagulation/DMF, reactive two-component coating, added crosslinker, pigmented or foamed formulations, PVC plastisol, rubber, hot-melt or membrane lamination, coated felt/nonwovens, synthetic leather, tyre cord, medical articles, garments and made-up tents are outside this profile. Fibre manufacture, PET polymerisation, weaving, upstream dyeing/finishing, consumption and end-of-life are separate stages. A materially different route requires reviewed extension, not a claim of whole 27997 coverage. Sources: unsd-cpc3-notes-2025; jrc-textiles-bref-2023; covestro-dln-w50.

PALTEX’s dated 2020 manufacturer article independently describes water-based PU coatings on woven polyester. It supports a historical market example only: the article does not establish this profile’s single-layer formulation, electric dryer, present supplier recipe or numeric performance. Those conditions require actual foreground records. Source: paltex-pu-woven-2020.

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	Weigh accepted finished composite rolls on calibrated scales under cp_output, subtract measured core/wrap tare and use the same conditioning state for output and inventory denominator.
area_mass	ready_woven_pet; finished_coated_fabric	Mass	kg	If raw records use m2 or linear metres, measure same-grade areal mass and width; convert area multiplied by kg/m2. Preserve any verified public Area property rather than rewriting it to Mass; generic waterproof fabric is not proof of this product identity.
wet_dry	aqueous_pu_dispersion; dilution_water; drying_water_vapour; pu_rinse_wastewater	Mass	kg	Distinguish wet dispersion mass, dry nonvolatile coating mass, retained water, released vapour and wastewater. Measure solids/moisture; no catalogue solids fraction is a universal conversion.
energy_preserve	mix_electricity; dry_electricity; finish_electricity; clean_electricity	Net calorific value 93a60a56-a3c8-11da-a746-0800200c9a66	MJ	Use metered kWh times 3.6 MJ/kWh; preserve public property and Units of energy 93a60a57-a3c8-11da-a746-0800200c9a66. Assign disjoint meter coverage.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Dry coating-ready woven PET, completed prior dyeing/finishing; delivered ready-formulated aqueous PUD; externally supplied process water
starting_condition_role	Upstream supplier handover to coating foreground
product_classification_scope	Narrow candidate subset of CPC 3.0:27997; classification title does not cover all routes
recursive_input_rule	For bought already PU-coated fabric, record its actual product state and linked upstream coating dataset; do not treat it as uncoated PET or recursively recreate its coating. Recoating is outside this single-coating profile.
upstream_dataset_requirement	Link compatible fabric, PUD, electricity, water and each packaging component datasets separately; disclose fibre/polymer, weaving, dyeing/finishing and chemical supply gaps and actual inbound transport coverage
disclosure	Factory/period; supplied substrate processing state; composition; electric-only drying; rinse treatment handover; utilities and upstream/transport links; missing stages

rule_id	applies_to	rule	source_ids
boundary_foreground	all processes	Include receipt/mixing, knife application, electric drying/cooling, trim/inspection/winding, actual packing, batch cleaning, attributable start-up/rework and measured outgoing wastes/releases. Internal wet-coated transfers are not additional market outputs.	jrc-textiles-bref-2023
boundary_wet	equipment_clean	Stop at untreated wastewater handover to a documented external treatment recipient. Treatment and its elementary discharges require a linked treatment dataset. Direct discharge or on-site treatment is not represented; cleaning is mandatory data coverage even if a batch has no rinse event.
boundary_routes	product applicability	Separate previous fabric wet finishing, agricultural feedstock and fibre/polymer manufacture from coating. Other formulation chemicals, heat carriers, maintenance inputs or wastewater-treatment routes require distinct atomic rows and reviewed scope extension before complete-site claims.	covestro-dln-w50
boundary_claim	dataset	This is manufacturing foreground, not automatically complete cradle-to-gate. Require all disclosed compatible upstream and transport links for an expanded footprint. Distribution, bag sewing, use, cleaning by consumers and end-of-life are excluded.

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
receipt_mix	Substrate receipt and dispersion preparation	required	All products in this profile	Manufacturing foreground	per 1 kg reference flow
coat_dry	Direct knife coating, electric drying and cooling	required	All products in this profile	Manufacturing foreground	per 1 kg reference flow
finish_pack	Final inspection, trimming, winding and packing	required	All products in this profile	Manufacturing foreground	per 1 kg reference flow
equipment_clean	Batch-attributed equipment rinse and effluent handover	required	All products in this profile	Manufacturing foreground	per 1 kg reference flow

Conditional exchanges are described on their individual cards; absence requires actual route records, not an assumed zero. Supplier formulation is one delivered product exchange; separately purchased additives need separate rows. Internal coating/wet-fabric transfers and recovered returns are reconciled without duplicate boundary exchanges. Only accepted final fabric is the quantitative reference. All ordinary mass rows use Units of mass 93a60a57-a4c8-11da-a746-0800200c9a66.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
allocation_trace	shared line	Avoid allocation by batch separation and submetering. For inseparable utility totals, use measured load and logged runtime with actual cleaning campaign attribution; preserve the causal relation and test sensitivity. Do not allocate by equal kg intensity across grades with different coating add-on or drying burden.
allocation_coproduct	downgraded cloth; exported scrap	Determine waste versus saleable co-product using actual quality, recipient and market records. Prefer subdivision; if joint burdens remain, justify a measured physical causal driver, otherwise document period-specific economic shares and sensitivity. No default price or displaced-fabric credit is prescribed.
allocation_rework	internal return and rework	Retain all rework/mixing/drying utilities and losses, carry internal returns through stock balance and count accepted fabric once. Record exported waste treatment separately; no burden-free recovered dispersion assumption.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
normalize_batch	all inventory rows	Divide attributable batch exchange by accepted net finished coated-fabric mass in kg; retain each exchange numerator unit. The final product row is 1 kg.	attributable batch exchange; accepted net mass; cp_output	exchange per 1 kg reference flow
convert_electricity	mix_electricity; dry_electricity; finish_electricity; clean_electricity	Convert measured kWh to MJ with 3.6 MJ/kWh before batch normalization; preserve public Net calorific value and energy unit group.	metered kWh; cp_mix_energy; cp_dry_energy; cp_finish_energy; cp_clean_energy; cp_output	MJ per 1 kg reference flow

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_composition	ready_woven_pet; aqueous_pu_dispersion; finished_coated_fabric	Verify PET composition and previous finishing state, PU grade, additives, wet/dry composition, dry coating add-on and physical batch acceptance. Supplier film tests or marketing are not finished-fabric quality/lifetime evidence.	supplier specifications; SDS; batch solids and fabric tests
dq_balance	all rows	Reconcile substrate and nonvolatile PU with accepted composite, offcuts, rejects, residue and stock/rework; separately reconcile coating water with retained moisture, rinse/stock and vapour. Investigate unclosed balances, not assumed yield/loss.	weighing; solids/moisture; separate material/water balances and uncertainty
dq_period	all rows	Use matched complete representative reporting-period production, cleaning, maintenance, start-up and rework coverage. Record calibration, missing fields, allocation and all actual ancillary material components. No default temperature, energy, recipe or yield.	period logs; calibration; attributable meter and stock records
dq_release	drying_water_vapour; drying_ammonia_air; pu_rinse_wastewater	Assess formulation-dependent volatiles and capture routes. NH3 is conditional, not all aqueous dispersions emit it. Add each actually relevant species as one row before complete release claims; unknown release, unmeasured residue or recipient treatment gaps remain explicit.	composition audit; representative emission tests; controls; treatment handover evidence
dq_upstream	linked background supply	Match PET processing state, recycled fraction, PU formulation, electricity geography/voltage, water supply and package composition. Disclose any absent upstream dyeing, water treatment or transport link.	supplier records and compatible upstream dataset references

9. Validation Rules

rule_id	applies_to	rule	source_ids
validate_scope	product and route	Require declared PET/PUD profile, electric dryer and untreated rinse handover; reject claims for other coating chemistries, wet coagulation, lamination or complete 27997 coverage.	unsd-cpc3-notes-2025
validate_reference	all rows	Require positive measured net composite output, finished_coated_fabric reference link, exclusion of packaging and a common per 1 kg denominator. Area-based raw measurements require actual same-grade mass conversion.
validate_balances	all processes	Require material, water and energy reconciliation with disjoint meters, internal return, rework, stock change and conditional stream evidence. Measured wastewater is not freshwater release; captured condensate is not air emission.
validate_identity	UUID-bearing rows	Recheck actual flow type, composition, supply route, public reference property, unit group, immediate environmental medium/subcompartment and official Chinese names. Disclose blank identities and never force generic waterproof fabric or neat resin onto the output/PUD input.
validate_complete	dataset claim	Require every real chemical, utility, package, waste and elementary species as a specific exchange with matched protocol. Absent conditional rows need evidence; uncertain or skipped release checks cannot be described as complete validation.	jrc-textiles-bref-2023

10. Published Dataset Profile

Field	Value
dataset_role	Manufacturing foreground for declared waterborne PU directly coated woven PET roll fabric
downstream_use	secondary_dataset; background_dataset
allowed_use	Only after review: declared single-coating, electric-drying profile with compatible upstream supplier and off-site waste treatment datasets and disclosed transport
excluded_use	Whole classification, other fibres/chemistries/lamination, synthetic leather, made-up bags, consumer use/lifetime, health or regulatory approval, automatically complete cradle-to-gate
required_metadata	All qualifiers; factory and period; net accepted output; measured area conversion; wet/dry coating basis; separate utilities; stock/rework; packaging; actual effluent recipient; upstream and transport links; conditional presence; unresolved identity
required_quality_disclosure	Measurement and allocation coverage; water/material closure and uncertainty; volatile-species screening and detection limits; excluded routes; incomplete upstream/treatment links; candidate evidence limits
update_trigger	Substrate finish/fibre, recycled profile, coating composition/layer, added chemicals, heat route, site supply, packaging, waste fate, emission controls, new measurements or verified identity change
