| Use advice for data set | Scope: This EPD covers the product Type II Technical Textile, more specifically the T2121E as representative product. This product is a technical textile made out of a combination of a polyester (PET) fabric and polyvinylchloride (PVC) coating with a polyvinyl fluoride (PVDF) and acrylic lacquer finish. The fully coated fabric weight is 900 g/m. The calculations are based on average yearly production data for 2019. The producing company is Sioen Industries NV. The above named products are produced at the production sites of Mouscron (BE) and Flixecourt (FR). System boundary: This EPD is cradle to gate with options, modules C1-C4, and module D: The analysis of the product life cycle includes production of the basic materials, transport of the basic materials and manufacture of the product, which are declared in modules A1- A3. In module A4, the burden of transporting the manufactured product to the customer is declared. The deconstruction and demolition stage C1 has not been included, since this is largely dependent on the specific project. Also, the C1 stage has been assumed immaterial. One scenario of the end-of-life (EoL) stage is considered. It is the incineration of the technical textiles in the incineration plant. This is taken into account in module C4. The transport of the used product to the final disposal was also modelled (module C2). Potential credits for electricity and thermal energy resulting from the waste incineration plant are declared in module D. | ||
| Technical purpose of product or process | These products are (mainly) applied in tensile architecture. Tensile structures typically consist of 3 main components: a primary structure, connectors, and tensioned fabric, such as the Type II technical textile. These structures may be stand-alone or integrated with (existing) regular buildings. Many different construction forms are possible, such as faade coverings, sun-shading elements, roof coverings,... either for permanent or temporary use. The standard lifetime of the fabrics used in tensile architecture ranges from 15 to over 30 years. For lightweight Type II fabrics, the lifetime is typically 15 years. This EPD (and the underlying LCA) has been made to allow customers to quantify the ecological impact of their constructions, as well as to allow comparison with other material types. | ||

| General comment on data set | The product is a technical textile made from a polyester (PET) fabric, coated with PVC and a finishing lacquer. The base fabric is a woven textile based on high-tenacity multifilament polyester (PET) yarns. Each side of the fabric is coated with a well-impregnated adhesion layer, a main layer consisting largely of PVC, UV stabilizers, flexing additives and other additives, and a thin acrylic and PVDF lacquer top coat which allows for a better cleaning ability, improved UV resistance and perfect weldability. The declared product has an average weight of 900 g/m. | ||

| Technology description including background system | The production of the PVC coated fabric starts with the production of a woven fabric made from polyester (polyethylene terephthalate, PET) yarn. This is done by beaming, followed by weaving to the desired width in the weaving plant in Mouscron, Belgium. After quality control, the woven fabrics are transported to the coating site in Flixecourt, France. At Flixecourt the PVC plastisol is made from PVC powder, DINP, pigments and additives. The plastisol is knife-coated onto the fabric in several steps with gelation occurring by intermediate (and a final) heating step(s). The first coated layer differs in composition to achieve optimal adhesion. After complete coating and gelation, the lacquer layers (based on acrylics and PVDF) are applied. The consumed solvents are quantitatively evaporated from the material. The resulting vapours are treated at post-combustion to harmless gasses and water. The produced material is inspected and tested according to ISO 9001:2015 Technical data: The technical specifications of the declared product is given in the table below. Declared unit: In this study, only the production, transport to the construction and the EoL of the PVC-coated textile is included. Therefore the reference unit is a declared unit: 1 m PVC coated polyester textile Type II (T2121E) with a mass of 0,9 kg | ||
