My client wants to know if the fabric I’ve proposed for their project is extrusion coated. What’s that and how do I find out?
Coating is the process of adding a semi-liquid to a fabric base; there are several different methods used. Extrusion coating is a technique in which resin pellets are fed into an extruder, where they are melted and combined into a homogenous solution. This solution is pumped through a die to form a molten sheet, which is applied directly to a substrate. Further steps involve the coated material going through a series of rolls to ensure that the coating fully adheres to the substrate. Extrusion coating is sometimes used for fabrics where a heavier coating is desired on the finished material, but there’s really no way to tell which coating technique was used without asking your fabric supplier.
