Coating and lamination techniques are used to impart properties to fabrics which are not necessarily those naturally assumed by textile fabrics. Having widespread application across a range of technical textiles sectors, they increase functionality and durability as well as value. They can include; waterproofness, increased abrasion, stain, flame and UV resistance, retro-Reflection or Fluorescence, anti microbial or Phase Change Materials.
These functions can be imparted using a range of application methods, dictated by the materials being processed and the required outcome, whether they are applied as a coating or laminate is also determined by this criteria. The definition between the two is a technicality relating to the application method, generally coatings are applied to a fabric in their preparatory state, often in liquid form. Lamination requires the pre-preparation of a laminate membrane that is then applied to the textile.
The application for coated and laminated textiles is widespread across a variety of technical textile sectors, these include;
Automotive and Aerospace
Vehicle interiors- textiles often laminated onto interior components such as door panels.
Medical and Hygiene
Anti Bacterial Coatings
Waterproof breathable Hydrophilic membranes
Construction and Engineering
Tarpaulins
Bulk bags
Interiors
Upholstery- Stain resistance
UV resistance
Technical Apparel and PPE
Waterproof Breathable Membranes
Phase Change Materials
Fluorescence
Apparel
Fashion, luggage and accessories- textured looks such as high shine or ‘wet’ look
PVC/Faux leather
Sports and leisure
Sail cloth
Bouncy castles
Coatings and laminates will interact differently with the fabric; this is due to the way in which they affix to the textile surface. Figure A demonstrates how a coating covers the surface of the fabric, as applied in liquid form, it is able to penetrate the fabric structure, filling the air pockets and bridging the interstices. Figure B depicts how a laminate sits on the fabric surface, the fabric retains its air pockets and the laminate has fewer points of contact.
