Are you looking for more information regarding the coating of textiles? We’ve got you covered! In basic terms, the goal of the coating process is to allow substrates to take on additional properties and capabilities that they normally would not be able to obtain. Depending on the type of coating applied, it is possible to make a textile more durable as well as water, stain, flame, or UV resistant.


Coating Defined


“The term ‘coating’ can apply to the adherence of a textile membrane to the fabric surface, or to a coating of micro- or nano-particles that adhere to the fibre surface forming a ‘substantial’, but not necessarily ‘continuous layer.’”


Coated Textiles


A coated textile is comprised of at least two layers, with one being a textile fabric and another being a polymeric layer. The polymeric layer is “applied in liquid form in a solvent or water base, which evaporates off to leave the polymer behind, applied to one or both surfaces.” The bonding becomes possible with evaporation or a curing process.


Coating vs. Lamination


The way in which additional properties are transmitted depends largely on the material and the desired result. These are also the determining factors for whether a coating or laminate is used to apply these properties. Commonly, coatings are applied to fabrics in a liquid form. On the other hand, lamination “requires the pre-preparation of a laminate membrane that is then applied to the textile.”

When a coating is applied to a fabric, the liquid form allows it to permeate the air pockets and close gaps. In contrast, laminate simply sits on top of the fabric, making it less invasive than a coating.


Technical Textile Sectors

Below are some of the ways that coatings are utilized in different sectors:

  • Automotive/Aerospace – Used in vehicle interiors. Textiles are typically laminated onto door panels.


  • Medical/Hygiene – Used for anti-bacterial coatings and waterproof hydrophilic membranes.


  • Construction/Engineering – Used for tarpaulins and bulk bags.


  • Interiors – Used for UV resistance and upholstery stain resistance.


  • Technical Apparel/Personal Protective Equipment (PPE) – Used for fluorescence, phase change materials and waterproof breathable membranes.


  • Clothing – Used to obtain textured looks for clothing, luggage, and various accessories.


  • Sports/Activities – Used for sailcloths and inflatables.
