The seat cover is the outer layer of a car seat, and it can be held in place with buttons, zippers or Velcro fasteners. It can be made of cloth or leather, and it is usually washable. The fabric must be dustproof and stain-resistant, and it should also be resistant to moisture. The material should also be durable enough to resist the abrasion of the passenger’s body against the seams, and the corners and protruding parts of the seat must be strengthened.
There are many different types of seat covers to choose from, and the material used in each will have a large impact on how comfortable it is. A few of the most common materials include neoprene, canvas and velour. Each has its own benefits and drawbacks. For example, neoprene is highly water-resistant, but it can feel cold against the skin in hot weather. Canvas is also water-resistant and is durable, but it can be stiff against the skin. Velour is a soft, stretchy material that has a luxurious feel. It is comfortable, but it does not have much abrasion resistance or breathability.
A scrim fabric is often laminated to the top of the cover, and it can be either polyester or polyether polyurethane foam, which is modified with flame-retardant additives for use in seat fabrication. This is an important step, as it provides a flat substrate for lamination and assists the cover fabric to slip over the squab and cushion.
