Double-sided needle-punched ceramic fiber blankets are produced via a dry forming process without any chemical binders added throughout production, making them eco-friendly binder-free needle blankets. The manufacturing process begins with loose ceramic fiber cotton settling naturally onto a cotton collecting mesh belt to form an even fiber mat, which is then reinforced and shaped through double-sided needling technology.
Core Functions of the Needling Process
The needling process is a critical step to boost product performance. Double-sided needling of blown long fibers greatly increases interweaving and entanglement between fibers, significantly improving the blanket's toughness, resilience and tensile strength. Meanwhile, this process effectively enhances the blanket's delamination resistance and mechanical stability, delivering smoother surfaces and more uniform internal structure.
Craft Details Determine Product Quality
While general workflows of various needling processes are largely similar, blankets with neat needle tracks and clear textures feature a finer appearance as well as uniform fiber distribution and consistent structure. Such products usually deliver superior tensile and anti-delamination performance.
Our Production Procedures & Quality Assurance
As a professional manufacturer of ceramic fiber needle blankets with years of experience, we adopt advanced double-sided needling production lines with strict control over every procedure: raw material selection, fiber blowing, cotton laying by sedimentation, needling forming, heat setting, cross & longitudinal cutting, and rolling & packaging. No binders are used in the whole process to guarantee stable heat resistance, uniform structure and outstanding mechanical properties.
