Being woven by doubling filoselle, the strength of fabric is enhanced. The   fabric made of doubling filoselle is double stronger than the fabric made of filoselle.Polyester   multifilament yarn's surface is smooth, and has characters of anti-abrasion and high tenacity.   After doubling, the tenacity will be enhanced, as well as anti-abrasion. Therefore, the fabric will   get good air-permeability, great water leaking, and anti-abrasion.
