Custom Spiral Nonwoven Needle Rotating Body Needle for Automotive Filter Materials

Custom Spiral Nonwoven Needle Rotating Body Needle for Automotive Filter Materials. Twisted Triangular Design: Uniform resistance distribution for longer service life and reduced localized wear. High Needling Efficiency: Altered barb alignment grabs more fibers per puncture for faster production speeds. High Carbon Steel Material: Precision heat-treated for superior durability, wear resistance, and robust bending strength. Multiple Barb Styles: F, G, B, GB, L, K types available to match specific fiber and fabric requirements. Balanced Strength Ratio: Improved MD:CD tensile strength ratio ensures more uniform fabric performance. Customizable Dimensions: Custom gauges, needle lengths, and working part lengths available upon request. Optimized Surface Quality: Reduced fabric surface interference for a smoother and more consistent finish. Dimensional Stability: Twisted geometry enhances fabric dimensional control during the needling process.
