摘要： A cut resistant fabric and a method of manufacturing a cut resistant fiber is disclosed herein. The fabric comprises a Ultra High Molecular Weight Polyethylene (UHMWPE) material and a sheet shaped wollastonite filler. The sheet shaped wollastonite filler is treated with a coupling agent and mixed with the UHMWPE material. A thickness of the sheet shaped wollastonite filler is less than 10 micrometers (µm). The method comprises providing the sheet shaped wollastonite filler having a thickness of less than 10 µm and treating the sheet shaped wollastonite filler with a coupling agent at a first predefined temperature to obtain a uniform solution. The method further comprises mixing the uniform solution with a fiber solution comprising UHMWPE resin at a second predefined temperature.
