Coated fabrics are fabrics that have been coated with a layer of special protective finishes. A uniform coating is given on the surface (back or front) of different types of fabrics. The most important advantage of coated materials is their wind and water repellency. Other purposes of coating include corrosion prevention, stain resistance, increased strength, and durability.
The coating materials usually give the fabric a shine but it can also be mat. They are usually very dense and thick materials – you cannot expect it to be like other woven and knit materials. But at the same time they are flexible enough for a variety of uses. Usually the dense coating prevents the fabric from breathing. But today there are breathable coated fabrics also
Protective uniforms of policemen and other such occupations, rainwear, curtains that protect against strong wind and rain, table cloths, placemats, hats, bags, upholstery – there are no end to the uses of coated fabrics in our everyday lives
Different types of Coated fabrics
Different types of Coated fabricsFabrics with polytetrafluoroethylene finishMaterials with Fluoro-chemical finishesPVC coated fabricsWaxed canvasMaterials treated with Waterproofing gel glueDecorative coating with resinFlame-proof fabric
Fabrics with polytetrafluoroethylene finish
These are materials on which special polytetrafluoroethylene finishes like Teflon or Scotchguard have been applied. This is intended to protect the fabric surface from water as well as stains. You can apply these coatings with over-the-counter products – so even if the coating is gone, you can still make it water repellent and stain-resistant by reapplying the finish.
The best thing about this finish is that the coating does not close pores – this makes the material still somewhat breathable.
Gore-Tex fabric is a very popular branded Teflon-coated material used to make rainwear, outdoor gear like hiking boots, bags, and outdoor jackets.
Materials with Fluoro-chemical finishes
DWR or Durable water-resistant coating is a fluoropolymer coating that is applied to allmost all rainwear. It is the best coating for water repellency. In fact, when you buy outdoor gear, it is best to check if this coating is given to prevent being drenched when the rain strikes.
PVC coated fabrics
This is a Vinyl / Plastic (Polyurethane) laminated material ie a material with polyurethane coating. Any material (knitted or woven) can be laminated with vinyl. The material will have a shiny plasticky side on one side and a knitted or woven or a non woven backing on the other side.
Vinyl coated polyester fabrics are popularly used to make outerwear. Usually PVC coated fabrics have a stretch. The material is susceptible to high heat.
K-Kote is a waterproof polyurethane coating. Faux leather can be called a vinyl coated fabric as the vinyl is coated on a backing and the surface is given the impression of real leather.
Oilcloth is a very durable synthetic material with a vinyl coating. It is popularly used to make table coverings.
Thermoplastic polyurethane coating is a less durable alternative to polyurethane laminate.
This is a cotton canvas fabric coated with paraffin-based wax – the material is very flexible and is available in very nice colors. It is used to make backpacks. The material is beautiful but it creases a lot.
Materials treated with Waterproofing gel glue
This gel glue available at shops can be brushed on the surface of materials to make them waterproof and it is easy to apply. It gives a transparent finish when dry.
Rubberized coated fabrics (Latex rubber coating), silicon coated fabrics, materials with acetate coating, Resin coated fabrics are other important coated fabrics
Decorative coating with resin
Coating can be used to change the texture of a fabric. You can spray or apply resin coating mixed with glitter to give a metallic sheen to fabrics. A glossy wet look or a matt feel can be given to fabrics with other types of coatings (PVC-coated).
This fabric has a flame-retardant coating which prevents the material from getting burnt or atleast stop the burning when the flame source is removed. It is usually used in commercial buildings.
There are countless garments made out of coated fabrics in the market but for a layman, it is difficult to sew coated fabrics. You have to finish the garment without causing harm to the surface of the material. When you use your metal presser foot on the surface of the coated material, the pressure foot may refuse to move across the material. This is very frustrating.
You will have to use a Teflon presser foot. The coated fabrics are also thicker than your normal fabrics. So all the problems of dealing with thick seams are yours. Sewing these fabrics can dull your sewing machine needles very fast.
The coating on the surface can be destroyed easily, so you have to care for it as if it is a delicate fabric. You can clean it with a damp sponge gently. Do not use softeners or harsh detergents to wash it. Dry flat.
