In chenille yarn production, the 7-tooth and 1-tooth separating blades serve different purposes.
The 7-tooth blade is typically used for coarse and thick yarns, suitable for high-strength, wide fabrics. It runs at low speed with even feeding to ensure yarn stability. Its advantage is rich, full texture, but the downside is slightly lower output and less precision for fine yarns.
The 1-tooth blade, on the other hand, is ideal for fine yarns and lightweight fabrics, commonly used in high-precision fabric production. It operates at higher speeds with continuous feeding, offering higher efficiency. Its advantage is high output and smooth yarn surface, but the pile effect is weaker, making it unsuitable for heavy products.
It’s worth noting that Kingkangda chenille machines are designed for flexibility—both the 7-tooth and 1-tooth separating blades are interchangeable, allowing users to switch according to production needs. Choosing the right blade depends on yarn type, fabric requirements, and production habits to achieve optimal results.
