This machine is a double-sided multi-functional cotton and wool rib knitting machine with two runways for needle plate and four runways for needle cylinder. The large plate gears and large tripod gears are designed with oil immersion design and use high-grade imported lubricating oil, so that the machine runs more smoothly and noise is low, and the transmission gears are more durable and not easy to wear. You can switch between ribbed, cotton and wool fabrics by just changing different triangles, and you can weave various patterns and colors of fabrics through different triangle arrangements, such as dobby fabric, knitted cotton felt, stretch health cloth, twill, air layer, sandwich liner, bubble velvet, double-sided mesh, mercerized cotton. Adding spandex device can weave elastic double-sided cloth and other high-grade men's and women's fashion fabrics.
