Soft and lustrous, strong light will tend to discolor and disintegrate the fiber. Difficult to clean, the fibers will tend to mildew in damp climates. Its low cost and blendability with other more expensive fibers make it a popular choice. The fiber. is reasonably colorfast and abrasion resistant, but will tend to rot under long exposure to direct sunlight. Synthetic Fibers These petroleum-based fibers have been developed over the last sixty years as an alternative to natural fibers and are often blended with them in an effort to achieve the best properties of each.
Polyester is strong and cleanable and stands up well under direct sunlight.
Flame and abrasion resistant, it is often blended with natural fibers to soften its feel. Recent developments have led to a finely extruded polyester fiber. Strong, with natural stain resistant properties, olefin is a bulky fiber. Often it is used to create heavy textured causal fabrics. These fabrics when loosely woven require a latex backing for added strength.
