Chenille fabrics are made by twisting short fibers or filaments of different fineness and strength. The visible part is called surface yarn or decorative yarn, and the strong twist part is called core yarn. The core yarn increases the strength of chenille yarn, accounting for 25%~30% of the composition of chenille yarn, and decorative yarn is the main body, accounting for 70% ~75%, showing aesthetic effect and style of chenille yarn.
