Base Fabric, Denier And Weave
The base fabric is the textile reinforcement within the finished composite. Duletai uses polyester filament yarns. Denier describes yarn mass per length: a 1000D yarn has a mass of 1000 grams per 9000 metres. It does not identify yarn diameter, finished-fabric weight or breaking force.
A notation such as 1000D × 1000D 30 × 30 combines yarn information with a count whose basis must be stated. Confirm the direction order and the counting unit. Warp usually runs along a woven roll; weft crosses its width. Preserve these directions when cutting specimens.
Weave is another detail. Plain weave alternates over one yarn and under the next; basket constructions group yarns. The same denier and count can describe different finished performance. A short notation alone does not establish filament count, yarn quality or a particular weave.
Weight, Thickness And Roll Dimensions
| Field | Meaning | Detail to confirm |
|---|---|---|
| Weight, g/m² or gsm | Mass per unit area of the finished material. | Typical or minimum value, tolerance, conditioning and coating/base-fabric split where needed. |
| Thickness, mm | Distance between the finished faces. | Measurement pressure, sampling and tolerance. |
| Width, m | Dimension across the roll. | Usable width, selvedges, edge allowances and tolerance. |
| Roll length, m | Length in the unrolling direction. | Length tolerance, identification and any permitted joins. |
Thickness and area mass are independent measurements. Added coating may raise GSM without a proportional increase in tensile strength. Read the construction and strength results together.
For an arithmetic example, an exact 5 m × 50 m rectangle has an area of 250 m². At exactly 750 g/m², its calculated material mass is 187.5 kg. That excludes the core, wrapping and fittings, and does not establish the actual weight of a shipped roll.
Tensile, Tear And Peel Results
Tensile testing pulls an initially intact specimen. Tear testing examines the initiation or extension of a tear in a particular specimen arrangement. A fabric can perform differently in these tests because the yarns, coating and local damage interact differently.
Peel or adhesion testing separates joined layers. Identify the interface: coating to reinforcement, a laminated interface or a fabricated weld. Record whether the interface separated, the coating tore or the fabric broke. A coating-adhesion figure is not automatically a welded-seam rating.
Compare the same method, specimen width, direction and conditioning. For example, a force reported per 5 cm should retain that width basis. If a tear row uses an unusual unit or omits its method, ask for clarification rather than silently rewriting it into a more familiar form.
Surface, Colour And Functional Options
Glossy and matt describe appearance. Agree the face being supplied and compare samples under the same lighting. A photograph does not establish a gloss value or colour tolerance.
An options row describes requirements available for discussion, not features automatically included in every roll. Specify which combination is needed and what evidence will confirm it.
| Option | Question to resolve |
|---|---|
| Blackout | What light-transmission or opacity criterion applies? |
| Acrylic / PVDF finish | Which finish and face, with what cleaning, printing and welding requirements? |
| Anti-UV / weathering | Which exposure and retained property are assessed? |
| Anti-mildew / antibacterial | Which organisms, conditions and result are required? Fungi and bacteria need different claims. |
| Low-wick | Which cut-edge exposure and moisture-rise assessment apply? |
| Antistatic | Which electrical property, target range, method and conditioning are specified? |
| Chemical resistance | Which chemical, concentration, temperature and contact time are relevant? |
Approve a colour reference and acceptable variation for the chosen finish. Check print compatibility and other conversion requirements on a representative sample.
Temperature And Fire Requirements
A temperature range needs a description of the activity. Storage, stationary use, cold bending and repeated folding place different demands on a fabric. A service-temperature entry is not a welding-machine setting.
Fire-related entries may mix classifications and standard names. B1, M1 and NFPA 701 cannot be arranged into one universal ranking. Identify the standard, edition, method and construction covered by the report. An options list does not show that a model has passed every named test.
The fire-report guide explains what to check before accepting these descriptions in a specification.
Packing And Ordering Terms
A paper core, PE film and kraft wrapping describe packing components. They do not establish package dimensions, gross mass, pallet inclusion or transport performance. Confirm core size, handling arrangements, roll identification and protective packing separately.
MOQ is a commercial condition. Confirm the current quantity for the selected construction, colour and stock position. Distinguish linear yards from square yards and metres from square metres. An old example datasheet is not a current stock or price offer.
A Practical Comparison Checklist
- Exact product reference, construction, colour and finish.
- Units, direction and counting basis beside each value.
- Nominal, typical or minimum values and agreed tolerances.
- Named test methods, conditioning and any aged results.
- Separate evidence for welds and option-specific functions.
- Current order quantities, usable dimensions and packing terms.
Missing values should remain questions until they are confirmed for the offered material. Do not fill a gap with another model’s result. Use All Products to open the relevant model sheet and compare the same properties.
Common Questions
Does 1000D mean 1000gsm?
No. Denier describes yarn mass per length. GSM describes the mass per area of the finished material.
Is a thicker fabric always stronger?
Thickness alone does not establish strength. Compare the reinforcement and matching tensile, tear and adhesion results.
Are every listed treatment and fire grade included?
Confirm the selected options and supporting reports for the actual version being ordered.
