Problems solved by technology

Although this method can indeed improve the anti-cutting performance of polyethylene fibers, there are still two obvious problems: (1) These inorganic high-hardness materials are relatively hard, which not only wears out the preparation equipment, but also requires frequent replacement of equipment. Partial devices increase equipment investment and affect production efficiency; (2) It is also found through actual use that these high-hardness materials are easy to puncture the polyethylene fiber matrix during repeated use due to their low flexibility. The surface of the polyethylene fiber is damaged and the high-strength anti-cutting performance fails

Abstract

The invention relates to an ultra-high cut-resistant ultra-high molecular weight polyethylene fiber, which comprises an ultra-high molecular weight polyethylene matrix and carbon fiber powder particles dispersed therein, and the content of the carbon fiber powder particles is 0.25-10 wt%. The invention also relates to a preparation method of ultra-high cut-resistant ultra-high molecular weight polyethylene fibers and cut-resistant gloves woven therefrom. Tests have proved that the gloves woven with the ultra-high cut-resistant ultra-high molecular weight polyethylene fiber have soft hand feeling, no puncture feeling, and are comfortable to wear. According to the test of EN388-2003, the cut-resistant grade is 4-5. Compared with the application of other inorganic high-hardness reinforcing materials in the past, the production process of the ultra-high cut-resistant ultra-high molecular weight polyethylene fiber of the present invention is better for equipment loss, and the woven cut-resistant gloves have higher durability and better cut-resistant performance. longer.
