Interlock fabrics are gentle and soft, and have an excellent performance of breath-ability, absorbency, and recovery, which makes them suitable for sportswear. Different from rib knit fabric, interlock fabrics are seemingly comprised of two layers because of two rows of stitches, that is the reason why people sometimes call it “double-knit fabric”. The interlock fabrics produced by Goldensea Global include polyester spandex fabric, nylon spandex fabric, and polyester fabric. Polyester spandex fabric, as a man-made fabric, has amazing features of wrinkle resistance and superior elasticity. Such a fabric never stretches or shrinks, making it extremely durable and ideal for sports.Widely used in sportswear; Fashion; Footwear; Bedding and stuffing; Stuffed toys; Grab velvet; Seat belt; Luggage, etc.
With light weight, easy to clean and other characteristics, can effectively resist wrinkle, wear resistance, stain resistance, chemical resistance.
The fibers can be mixed with other man-made or natural fibers to share both benefits, such as polycotton which is strong, wrinkle-resistant, far more breathable than pure polyester etc.
Woven or knitted, polyester fibers can be easily modified for different fabrics which are silky touch.
