# Other knitted or crocheted fabrics

## 1. Scope and Applicability

This PCR applies to saleable knitted or crocheted fabric classified in CPC 3.0 class 28190, whether supplied greige, pretreated, dyed, printed, coated, laminated, heat-set, or otherwise finished. It covers fabric formation by knitting or crocheting and every producer-operated preparation, coloration, finishing, inspection, and on-site wastewater-treatment step needed to place the declared fabric lot at the factory gate.

Pile fabrics and terry fabrics classified in CPC 28110, woven or nonwoven fabrics, yarn, made-up textile articles, wearing apparel, and downstream cutting and sewing are excluded. Fibre and yarn production are upstream unless performed inside the reporting site and explicitly added as separate processes. A dataset shall declare the exact fibre composition, yarn form, knit or crochet construction, fabric width and areal density, finish state, coloration route, and moisture basis so that a greige intermediate is not represented as a category-wide finished fabric.

## 2. Product Category Identity

| canonical_pcr_id | pcr.food-products-beverages-and-tobacco-textiles-apparel-and-leather-products.knitted-or-crocheted-fabrics-wearing-apparel.other-knitted-or-crocheted-fabrics |
| classification_refs | CPC 3.0: 28190 Other knitted or crocheted fabrics |
| covered_products | Knitted or crocheted fabric other than pile or terry fabric, including warp-knit and weft-knit fabric and fabric containing elastomeric yarn or rubber thread, in the declared greige or finished market state |
| excluded_products | CPC 28110 pile and terry knitted or crocheted fabrics; yarn; woven and nonwoven fabrics; garments; made-up textile articles; cutting and sewing operations |
| representative_product | Knitted or crocheted fabric, other than pile or terry fabric, supplied as a declared production lot |
| production_route | Yarn preparation at the knitting line; knitting or crocheting; route-specific pretreatment, coloration, printing or finishing; inspection and release; on-site wastewater treatment when operated |
| market_state | Factory-gate fabric roll or piece, with greige, bleached, dyed, printed, coated, laminated, heat-set, or other finish state explicitly declared |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Provide a declared knitted or crocheted fabric lot, excluding pile and terry fabric, with the specified construction and finish state |
| How much | 1 kg net dry mass of saleable fabric at the factory gate |
| How well | Meets the declared fibre composition, construction, width, areal density, coloration and finish specifications, with rejected material excluded from the reference amount |
| How long or cycle | One production lot through release at the factory gate; no use-life function is assigned to this intermediate product |
| reference_flow_link | The mass of saleable fabric needed to provide the declared unit; all inventory exchanges are normalized to `reference_product` |

| Field | Value |
| --- | --- |
| Reference amount | 1 kg net dry saleable fabric |
| Reference product flow | Other knitted or crocheted fabric, excluding pile and terry fabric |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |
| Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` |
| Reference unit | kg |

No Tiangong Product flow UUID is assigned to `reference_product`. The reviewed Tiangong flow `73008d55-ab26-442b-be93-1e2869b6e66e` is explicitly limited to greige fabric before wet processing and is narrower than this PCR boundary.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| `reference_dry_mass` | reference product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Determine net saleable fabric mass on a dry-mass basis. Record measured as-received mass, moisture content or correction factor, excluded packaging, and rejected fabric; do not mix wet mass and dry mass without an explicit conversion. |
| `areal_density_disclosure` | product identity | Mass per area | g/m2 | Record the declared and measured areal density and the test or production-control method used; areal density is a qualifier and shall not replace the mass reference amount. |
| `energy_carrier_separation` | electricity, steam and fuels | Energy or carrier-specific property | kWh, MJ or kg | Preserve each purchased or produced energy carrier as a separate exchange. Record electricity in kWh, gaseous or liquid fuel on a declared net-calorific-value basis, and steam by mass with pressure and temperature or by measured delivered energy. |
| `water_mass_conversion` | process water and wastewater | Mass or volume | kg or m3 | Use measured mass directly or convert measured volume using documented density and temperature. Keep incoming process water and outgoing wastewater as separate exchanges. |

## 5. System Boundary

The foreground boundary begins with yarn and other declared materials received at the fabric-production site and ends with net dry saleable fabric released at the factory gate. Include the actual formation and route-specific wet or dry processing performed by the producer. Upstream production of purchased yarn, water, electricity, steam, fuels, chemicals, and packaging is represented by linked upstream datasets and is not recreated inside the foreground inventory.

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Yarn and separately purchased process materials received at the reporting site, with supplier identity, fibre composition, yarn form, quantity, moisture basis, and upstream dataset references declared |
| starting_condition_role | Foreground gate for fabric formation; purchased same-category fabric is permitted only for a finishing-only route and must be disclosed as an intermediate product input |
| product_classification_scope | CPC 3.0 28190 only; pile and terry knitted or crocheted fabric in CPC 28110 is outside scope |
| recursive_input_rule | If greige or partly processed CPC 28190 fabric is purchased for further treatment, record it once as an atomic product input with an upstream dataset and do not recursively reproduce its earlier knitting inventory |
| upstream_dataset_requirement | Use composition-, technology-, geography-, and period-representative datasets for every purchased yarn, material, utility, fuel, treatment service, and same-category fabric input |
| disclosure | Declare which of knitting or crocheting, pretreatment, dyeing, printing, coating, lamination, thermal or mechanical finishing, inspection, and wastewater treatment are on-site, outsourced, absent, or already represented upstream |

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `boundary_route_disclosure` | all foreground datasets | Include only operations actually performed for the declared fabric lot and disclose every excluded or outsourced route step; do not model greige-only production as finished fabric production. | `un-cpc-v3-28190`; `eu-pef-method-2021`; `eu-textiles-bat-2022-2508` |
| `boundary_atomic_recipes` | wet processing and finishing | Record every recipe chemical, dyestuff, pigment, binder, coating, auxiliary, fuel, refrigerant, waste stream, and elementary emission as its own exchange; the example cards below are a minimum process map, not a selector or aggregated carrier. | `eu-textiles-bat-2022-2508` |
| `boundary_wastewater_treatment` | wastewater | Include on-site wastewater treatment when operated; otherwise record one wastewater waste flow to the identified off-site treatment dataset and avoid double counting treatment. | `eu-textiles-bat-2022-2508` |
