Abstract

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.

First claim

What is claimed is:

1. A method for preparing a cut resistant fiber, comprising:
providing a sheet shaped wollastonite filler having a thickness of less than 10 micrometers (μm);
treating the sheet shaped wollastonite filler with a coupling agent at a first predefined temperature to obtain a uniform solution; and
mixing the uniform solution with a fiber solution comprising Ultra-High Molecular Weight Polyethylene (UHMWPE) resin at a second predefined temperature.

2. The method of claim 1 , wherein obtaining the uniform solution comprises:
mixing a dispersing agent with the sheet shaped wollastonite filler to obtain a mixture of the disperse agent and the sheet shaped wollastonite filler; and
adding the mixture of the dispersing agent and the sheet shaped wollastonite filler to a white oil, wherein the white oil is a fiber spinning solvent.

3. The method of claim 1 , wherein the sheet shaped wollastonite filler has a length less than 100 μm, and a width less than 50 μm.

4. The method of claim 1 , wherein the first predefined temperature is 80° Celsius (C) and the second predefined temperature is 140° C.

5. The method of claim 1 , wherein the coupling agent comprises at least one of gamma-Aminopropyltriethoxysilane (KH550), and polyorganosiloxane (Penta-1006).
