Textiles are used in all kinds of public and community environments to provide texture, color, acoustic quality, and, in some cases, privacy (Figure 12.5). Woven textiles may be natural or a blend, but in community environments, it is most likely to be synthetic, such as nylon, polyester, acrylic, microfiber, aramids, and thermoplastics.81 Nonwoven fabrics or bonded fiber fabrics are synthetic and typically made with polyethylene or polypropylene bonded thermally or with a resin.82 Durable coated fabrics are nonwoven textiles constructed in layers including a coating made of vinyl, polyurethane, thermoplastic elastomers, or silicone that provides protective performance characteristics. Some of the performance characteristics of textiles include abrasion, UV, crocking, or flame resistance; textile strength, which tests for tearing, seam, and tensile strength; and finishing added for antimicrobial, stain, and flame resistance.83 Identifying the specific performance requirements is necessary for specifying a textile to meet the demands of the environment in which it resides. When specifying textiles, consider whether the textile is capable of being decontaminated using a variety of disinfection solutions or limited to “special” cleaners. Furthermore, consider how the textile meets the criteria for sustainability and human health.

The coated fabric is the textile fabric on which there has been formed in situ, on one or both surfaces, a layer or layers of adherent coating material (Fung, 2002). The coating is a process in which a polymeric layer is applied directly to one or both surfaces of the fabric. Types of coating methods are direct coating (where the polymer resin compound is spread evenly over the surface of the fabric), foamed and crushed foam coating (where polymer is applied to woven, knitted fabrics and also to fabric produced from spun yarns), transfer coating (where the polymer is spread on to release paper to form a film and then to laminate this film to the fabric), hot-melt extrusion coating (thermoplastic polymers are applied as granules to the material and then melted between moving heated rollers), calender coating and rotary screen coating (Singha, 2012).

Coated fabric refers to the composite fabric formed by coating a polymer or other materials on a fabric substrate. Many kinds of polymer solutions, such as silicone resin, acrylic resin, epoxy resin and polyurethane are commonly used. Among them, the acrylic resin film is transparent and does not susceptible yellow. It is chemically stable, weather resistant, flame retardant, low cost and has good adhesion to glass fiber. It has been widely used in construction, decoration, transportation and military fields.[1–4] In the curing process of coated fabrics, drying is the key process step and solvent diffusion is the key factor to control the drying rate, which determines the content of residual solvent in the film and affects the performance of the film.[5] During the development of coated textile materials, experimental methods are often used as a way to optimize important parameters such as solvent content, drying temperature, drying air speed and so on.[6,7] However, this approach requires repeated experiments with high costs and longer experimental times, and the solvent in the coating solution releases a large amount of smoke into the air. Therefore, it is desirable to predict the change of solvent concentration in coated fabric under certain condition by means of numerical calculation.

The use of coated textiles for protective clothing, shelters, covers, liquid containers and so forth, dates back to antiquity. Historically, the earliest recorded use of a coated textile is by the natives of Central and South America, who applied latex to a fabric to render it waterproof. Other materials, like tar, rosin and wax emulsions, have been used over the years to prepare water-resistant fabrics. Due to their vastly superior properties, rubber and other polymeric materials have become the preferred coatings. Today, coated fabrics are essentially polymer-coated textiles. Advances in polymer and textile technology have led to the phenomenal growth in the application of coated fabrics for many diverse end uses. Coated fabrics find an important place among technical textiles and are one of the most important technological processes in modern industry [27].
