| 1 | Intended application | Describe the end use and operating conditions first. The application helps determine the required material, weight, strength, and surface properties. | A disposable cover, filtration layer, agricultural crop cover, and reusable shopping bag may each require different fabric characteristics. |
| 2 | Fiber and polymer | Specify the fiber or polymer type and any requirements for recycled content, chemical compatibility, or heat resistance. Common options include polypropylene (PP), polyester (PET), and viscose. | PP spunbond is commonly used in lightweight packaging and hygiene applications; PET may be selected where higher temperature resistance is needed. Confirm suitability for the actual use. |
| 3 | Fabric construction | Name the required web-forming and bonding process, such as spunbond, meltblown, needle-punched, or hydroentangled. Construction affects texture, strength, filtration, and absorbency. | A layered spunbond-meltblown-spunbond construction may be specified for certain barrier applications; a needle-punched web may be appropriate for some geotextile uses. |
| 4 | Basis weight | Set the target basis weight in grams per square metre (gsm), together with an acceptable tolerance. A higher gsm generally means more material per area, but does not by itself guarantee strength or performance. | A project might request 40 gsm with a stated tolerance, while a heavier-duty use could require a higher weight confirmed through application testing. |
| 5 | Roll width | Specify the usable fabric width and width tolerance. Match the roll width to the converting equipment or finished-product layout to reduce trimming and waste. | Request a nominal width such as 1,600 mm only if it matches the equipment; confirm whether the quoted width is usable width or includes edge trim. |
| 6 | Roll length and outside diameter | Define the required length per roll, maximum outside diameter, and any roll-weight limit. These details affect machine changeovers, handling, and transport. | Provide a target length per roll and a maximum diameter that the unwinding station can accommodate; ask the supplier to state the expected roll weight. |
| 7 | Core size and winding | Confirm the core's inside diameter, core material, winding direction, and whether the roll must unwind from a particular side. Check compatibility with the machine shaft. | A 76 mm (3 in) core is used in many converting setups, but the required core size should be verified against the buyer's equipment. |
| 8 | Strength and elongation | Set minimum tensile strength and acceptable elongation in both machine direction (MD) and cross direction (CD), using an agreed test method and specimen conditions. | Ask for MD and CD results on a sample or technical data sheet rather than relying on a single general strength value. |
| 9 | Surface and functional treatments | State requirements such as hydrophilic or water-repellent finish, antistatic treatment, color, printing, or UV stabilization. Specify the test method and performance target where applicable. | For an outdoor crop-cover project, define the required UV-stabilization performance and intended exposure period; do not assume untreated fabric will meet it. |
| 10 | Quality, packing, and documentation | Agree on inspection criteria, roll identification, packaging, storage conditions, and required test reports or compliance documents. Approve a representative sample before production. | Record lot number, width, gsm, roll length, and inspection results on each roll label; specify moisture protection and pallet requirements for shipment. |
