Title:
POLYETHYLENE FIBER HAVING ULTRAHIGH ANTI-CUTTING PERFORMANCE AND ULTRAHIGH MOLECULAR WEIGHT AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/007943
Kind Code:
A1
Abstract:
The present invention relates to a polyethylene fiber having ultrahigh anti-cutting performance and an ultrahigh molecular weight. The polyethylene fiber comprises a polyethylene matrix having an ultrahigh molecular weight and carbon fiber powder particles dispersed in the polyethylene matrix, and the content of the carbon fiber powder particles is 0.25-10 wt%. The present invention further relates to a preparation method for the polyethylene fiber having the ultrahigh anti-cutting performance and the ultrahigh molecular weight and anti-cutting gloves woven from the polyethylene fiber. It is proved by means of tests that the gloves woven from the polyethylene fiber having the ultrahigh anti-cutting performance and the ultrahigh molecular weight are soft in hand feeling, free of tingling feeling and comfortable to wear, and by means of the EN388-2003 tests, it is proved that the anti-cutting performance level is from level 4 to level 5. Compared with the application of other inorganic high-hardness reinforcing materials in the past, the polyethylene fiber having the ultrahigh anti-cutting performance and the ultrahigh molecular weight in the present invention has the advantages that the device loss during production is lower, the woven anti-cutting gloves have higher durability, and the anti-cutting performance is maintained for a longer time.
