Crinkle Fabrics

Warp knitting combined with crinkling techniques creates warp knitting crinkle fabric. This fabric features a stretchy, textured surface with a subtle crinkled effect, achieved through an extended needle bar movement with EL. Its elasticity varies based on yarn selection and knitting methods.

Sports Wear

Equipped with the EL system, GrandStar warp knitting machines can produce athletic mesh fabrics with varying specifications and structures, tailored to different yarn and pattern requirements. These mesh fabrics enhance breathability, making them ideal for sportswear.

Sofa Velevet

Our warp knitting machines produce high-quality velvet/tricot fabrics with unique pile effects. The pile is created by the front bar (bar II), while the rear bar (bar I) forms a dense, stable knitted base. The fabric structure combines a plain and counter notation tricot construction, with ground guide bars ensuring precise yarn positioning for optimal texture and durability.

Automotive Interior

Warp knitting machines from GrandStar enable the production of high-performance automotive interior fabrics. These fabrics are crafted using a specialized four-comb braiding technique on Tricot machines, ensuring durability and flexibility. The unique warp knitting structure prevents wrinkling when bonded with interior panels. Ideal for ceilings, skylight panels, and trunk covers.

Shoes Fabrics

Tricot warp knitted shoe fabrics offer durability, elasticity, and breathability, ensuring a snug yet comfortable fit. Engineered for athletic and casual footwear, they resist wear and tear while maintaining a lightweight feel for enhanced comfort.

Yoga Clothing

Warp-knitted fabrics offer exceptional stretch and recovery, ensuring flexibility and freedom of movement for yoga practice. They are highly breathable and moisture-wicking, keeping the body cool and dry during intense sessions. With superior durability, these fabrics withstand frequent stretching, bending, and washing. Seamless construction enhances comfort, minimizing friction.
