Woven fabric patterns hold up longer than printed ones. Linen is a very strong and sturdy fabric, even more so than cotton. When purchasing an upholstered piece or upholstery fabric, be aware that the higher the thread count, the more tightly woven the fabric is, and the better it will wear. Choosing an upholstery fabric's color is the single biggest factor in fabric selection. Silk is so delicate that although it can be hand-washed it is best sent to the dry-cleaners. This tough material can be gently vacuumed, wiped with a damp cloth and cleaned with leather conditioner or saddle soap. Leather furniture can be rather expensive, although the same look can be achieved with the use of fake leather uphostery fabric. Acrylic fibers are also man made and include such brand names as Orlon, Acrilan, Dolan and Dralon. Wool is obtained from sheep fleece and the term "virgin wool" denotes new, not recycled wool. Chenille is also used for bedspreads and garments. Nylon is a manufactured fiber that is exceptionally strong, elastic, and lustrous. Microfiber upholstery fabric, which has increased in popularity over the years, is a blend of polyester and polyamide. Velvet has one plush side and one plain woven side. Chenille is commonly used for bedspreads or rugs, but makes an excellent fabric choice for upholstery. Leather is a very popular choice as an upholstery fabric, as it is delightfully soft yet resistant to spills and stains. Cotton is a popular plant based fiber that is used extensively for many kinds of upholstery fabric. Upholstery is the art of providing furniture with padding and covering generally in the form of upholstery fabric. A piece of furniture covered in chenille upholstery fabric will still look new in 10 years, depending on how well you take care of it. Linen is best suited for formal living rooms or adult areas because it soils and wrinkles easily. Olefin is a manufactured fiber that is strong and very lightweight. When blended with wool, polyester can cause pilling. Acrylic resists wear, wrinkling, soiling, and fading. Thread count refers to the number of threads per square inch of an upholstery fabric; just like you see when you buy linens for the bed. Jacquard is a fabric having woven patterns such as tapestries, brocades, and damasks. Jacquard designs may be simple or very elaborate. Backing is a sprayed coating or another layer of fabric applied to the back of fabric. A backing may be needed to give the face fabric more body or to make it more appropriate for upholstery. Upholstery fabrics are usually a little heavier and more durable than multi-purpose or drapery-weight fabrics. Olefin is a good choice for furniture that will receive heavy wear; however, it lacks the pliability and movement that natural fibers offer.
