Textiles, Chemical Fibers
Chemical fiber production is the process of transforming chemical raw materials into "silk" or "short fibers", in which blades undertake the key tasks of "shaping" and "fixed length cutting". Staple Fiber Cutting: Application scenario: Thousands of continuous synthetic fibers (bundles) sprayed from the spinneret need to be cut into fixed lengths (such as 38mm, 51mm cotton or wool short fibers) at high speed after stretching and curling, and used as spinning materials. Use of cutting tools: chemical fiber cutting knife, rotating cutting knife ring. Industry pain point solution: Chemical fiber has high friction and is prone to heating during high-speed movement, while ordinary blades are prone to wear or fuse. This scenario uses ultra-fine grain hard alloy (tungsten steel) or ceramic blades, combined with super mirror grinding technology, to ensure that the cutting edge has no micro notches, achieving high stability and high-speed cutting without melt adhesion. Winding&Waste Yarn Tripping: Application scenario: During the high-speed winding process of long fibers, when switching between fiber cakes or generating waste fibers, specific cutting blades or suction gun blades are required to quickly cut them off. Use of cutting tools: air suction gun blades, wire cutter blades. 2、 In the Textile&Non woven Processing industry, as fibers enter the spinning, weaving, printing and dyeing, or non-woven fabric manufacturing stages, cutting tools are mainly used for edge trimming, slitting, and finished product cutting of materials. Non woven Slitting: Application scenarios: Widely used in non-woven fabric production lines such as masks, sanitary napkins, diapers, filter materials, and automotive interiors. After the large roll of non-woven fabric is produced, it needs to be cut into the target width at high speed. Use of cutting tools: pneumatic slitting circular knife, slitting upper/lower knife, ultra-thin slitting disc knife. Industry pain point solution: The non-woven fabric has a fluffy texture and may contain abrasive impurities, requiring the blade to have extremely high sharpness to prevent "drawing" or "burrs" and ensure a smooth and clean incision. Fabric Edge Trimming: Application scenario: Real time online trimming of irregular edges (fabric edges) on both sides of a fabric on a loom (water jet, air jet, rapier loom) or printing and dyeing machine. Use of cutting tools: fabric edge cutter, rotary round scissors, pneumatic edge cutting complete set device. Clothing&Home Textile Cutting: Application scenarios: Used for cutting and trimming textile fabrics, carpets, curtains, etc. in large quantities of finished pieces or specific sizes. Using cutting tools: cutting machine computer driven straight knife, round knife, precision die. 3、 Henglida's cutting tool technology and material advantages in the textile and chemical fiber industry. Chemical fiber textile machinery usually operates at high speed 24 hours a day. In response to this characteristic, professional cutting tool manufacturers generally provide the following technical support: core technology dimension solutions and performance. Cutting edge materials are widely used, including Vangard (powder high-speed steel), hard alloys (tungsten steel), and high-performance ceramics (zirconia/alumina composite materials). The wear resistance of ceramic and tungsten steel blades is tens of times that of ordinary steel blades. The high surface finish of the blade is achieved through mirror level grinding (mirror polishing) on both sides and the cutting edge. The Ra value is extremely low, greatly reducing the friction coefficient between the fiber and the blade, preventing static electricity accumulation and chemical fiber hot melt adhesion. The combination of ultra-thin and high rigidity cutting disc cutter achieves ultra-thin (even less than 1mm) while maintaining excellent flatness and rigidity, ensuring that the cutting tool does not shake or jump at high-speed cutting speeds of over 1000 meters per minute.
