Taiwan Dyeing & Fabric (TDF) presents coated and laminated fabric constructions for projects that require both resistance to liquid-water penetration and transmission of moisture vapor. These are different performance characteristics and should be specified separately. The fabric structure, functional layer, test procedure, and conditions of use all affect how a proposed material should be evaluated for the finished product.
Water-resistance requirements should identify the relevant hydrostatic-pressure method and acceptance target. Moisture-vapor transmission requirements should identify the test procedure, reporting units, conditioning, and test conditions. The current page references JIS L 1099, ASTM E96, and BS 7209; buyers should confirm the applicable method and version for the actual material. A testing organization name is not itself a test standard or a guarantee of performance.
The product page lists microporous and hydrophilic coated and laminated fabrics, membrane fabrics, PTFE laminated fabrics, and two-layer, two-and-a-half-layer, and three-layer constructions. These descriptions are starting points for a technical discussion. Availability and suitability should be confirmed for the requested specification. Do not assume that all listed constructions share the same water resistance, breathability, hand feel, or downstream-processing characteristics.
A fabric test does not establish the performance of a completed jacket, cover, or other item. Seams, closures, seam-sealing compatibility, pattern design, and surface treatments can affect the final result. Identify whether testing is needed before and after washing, aging, or other conditioning. If comparisons are required, use equivalent test procedures and conditions; results from different methods should not be treated as directly interchangeable.
Provide the intended use, base-fabric preference, weight, width, color, construction, required tests, and estimated order quantity. Include a reference material or current performance problem where possible. Ask TDF to confirm the proposed specification, sampling process, available evidence, and commercial conditions. Any numerical improvement claim should be supported by a defined comparison and a relevant report before it is used in product documentation or customer-facing materials.
Our breathable fabric can be made according to individual client requirements. Hydrostatic pressure coefficient can reach 2000mmH2O – 20000mmH2O, seen as an ideal choice for waterproof breathable fabric. Besides, we also offer fabrics with different functions like reflective fabrics.
Water resistance and breathability depend on the selected construction and test conditions. Please contact TDF for the relevant specification and available test data. Any comparison should identify the tested fabric, reference material, test method and conditioning. Coating, surface treatment and seam-sealing requirements should be reviewed for the intended finished product.
