The textile industry manufactures products from a wide range of natural and synthesized materials which have typically been derived from one or more of four primary sources: animal, plant, mineral, and synthetic. These textiles are treated and shaped into myriad products, including but not limited to clothing, upholstery, and industrial fabrics.
The addition of textile coatings in the manufacturing process greatly enhances the value of textile materials by extending their useful life and preserving their aesthetic appearance. Coating methods and technology have evolved alongside the increasingly stringent needs of manufacturers and design engineers.
For example, textile coating technology has begun to incorporate eco-friendly options as manufacturers seek more sustainable and efficient coating solutions. Textile coatings can be custom-engineered to provide specific benefits and enhancements that improve the performance of textile products, which makes them useful in a wide range of industries.
Benefits of Polymer Coatings for Improving Textile Performance
Textiles may be subject to a number of external pressures and abrasive elements during everyday use. For this reason, a number of coatings have been developed to reduce the wear of textile materials. Polymer coatings, in particular, offer enhanced protection on the surface of textile products while still allowing for water evaporation through the fabric—a process that is often hindered by other coating materials. Here are the 10 primary benefits of polymer textile coatings:
1. Abrasion Resistance
Abrasion resistance is measured by rubbing flat materials against the fabric in question to determine the rate at which the fabric erodes. Polymer coatings create a layer on top of the textile fabric to add increased resistance to abrasion. It is particularly useful for materials that experience a great deal of friction, such as personal protective equipment (PPE), power transmission belts, backpacks, footwear, and synthetic leather products.
2. Adhesive Qualities
Textile fabrics can be coated with polymers to increase their adhesion and tack to other surfaces or polymers. For this reason, rubber polymer coatings are ideal for use in high-performance vehicle tires, power transmission belts, and seals and gaskets.
3. Air-Holding Capabilities
Polymer-coated textiles can incorporate resistance benefits to stop items like air or water from passing through the material. This makes them particularly useful in products that need to be capable of holding air, this would include items such as SCUBA buoyancy compensators, life vests, airlift bladders, blood pressure cuffs, pressure infusor bags, aerostates, etc.
4. Antimicrobial Properties
Polymers such as chitosan—a naturally occurring biopolymer derived sea creatures—display measurable antibacterial activity, sometimes with a reduction of up to 99%. Since surfaces coated with these materials remain clean and virtually free of bacteria, they are particularly useful in medical textiles, such as bandages, blood pressure cuffs, braces and prosthetics.
5. Flame Resistance
Polymer coatings may be combined with flame-resistant agents to create highly flame-resistant materials, which make them important in the manufacture of protective clothing for firefighters, fabric used in vehicles and airplanes, thermal ablatives for rockets, and safety curtains and carpeting.
Polymer coatings make textiles more sturdy and corrosion-resistant, significantly extending the service life of finished products ranging from household goods like towels and sheets to outdoor camping equipment and outerwear.
7. Noise Abatement
Textiles coated in polymer blends possess sound reduction properties. When sound waves are directed toward the materials, they are absorbed due to its porous nature, thereby preventing the movement of sound. This can be particularly useful in soundproofing layers in automotive, aerospace, and industrial applications.
8. Thermal Resistance
Materials coated with polytetrafluoroethylene (PTFE) or perfluoroalkoxy alkane (PFA) blends are able to withstand temperatures of up to 500° F. Like flame-resistant coatings, these polymer-coated textiles are particularly useful for safety products, automotive and aerospace fabrics, and firefighting apparel.
Polymer coatings provide an excellent means for waterproofing textiles. Their hydrophobic nature ensures that materials coated in certain polymer blends easily repel water and other liquids.
Polymer coatings may need to be bonded through the use of adhesives, RF, ultrasonic or hot air weldable. These types of fabrics are ideal where a durable sealed seam is required and normally sewn seams create unwanted holes in the surface. These weldable coated textiles are ideal for items such as weatherproof outerwear, inflatable vests, rafts, medical devices, and recreational BC vests.
Polymer Coating Applications
Polymer coated textiles are used throughout a wide range of applications and industries, including:
- Home furnishings
- Industrial and manufacturing
- Sports and leisure
- Protective materials

Coatings are polymer-based layers that cover a substrate. Some coatings are protective while others contribute additional attributes to a final fabric-based product. Enhanced properties may include improved resistances, enhanced durability, or protection from environmental wear.
Coatings can be applied to one or both sides of a fabric and different substrates cab be selected to address specific requirements. These fabrics include:
- Circular knits
Understanding Polymer Coating Systems
Polymer coatings represent a broad category of polymer-based materials that enhance different properties and protect different types of fabrics. Some of the most common polymers include:
- Ethylene vinyl acetate (EVA)
- Low-density polyethylene (LDPE) and high-density polyethylene (HDPE)
- Natural rubber (NR)
- Polyurethane (PU)
- Polyvinyl chloride (PPVC)
- Polyvinylidene chloride (PVDC)
- Polytetrafluoroethylene (PTFE)
- Styrene-butadiene rubber (SBR), a common type of synthetic rubber
Each of these chemicals provides unique protective or performance-driving characteristics.
Advanced Coating Polymer
Dynamic fabric products often require coatings that can provide more complex benefits such as antimicrobial properties or metallic or electrically conductive attributes. Today’s advanced coating solutions also include phase change coatings and increasingly smart textiles. Smart fabrics that are more reactive to electrical impulses and electronic commands may soon become an essential facet of fabric coatings.
