Abstract

The invention discloses a preparation method of glass fiber coated yarns for gloves. By adoption of rare earth salt and a coupling agent for glass fiber modification, wear resistance and lubricating performance of glass fibers can be improved, and accordingly strength, wear resistance and lubricating performance of the glass fiber coated yarns can be improved. The glass fiber coated yarns has highstrength of the glass fibers, integrates elasticity and toughness of spandex and can be directly used for manufacturing of cut-resistant gloves with cut resistance.

Description

technical field [0001] The invention relates to the technical field of glove processing, in particular to a method for preparing glass fiber-coated yarn used for gloves. Background technique [0002] In many industries it is desirable to provide protective articles, especially gloves, to protect employees from cuts. Ideally, these protective articles should provide satisfactory cut resistance while having suitable flexibility and durability. To this end, protective articles with these qualities have been manufactured from yarns that include "high performance" fibers for enhanced cut resistance. However, in the prior art, affected by the yarn material, the wear resistance, cut resistance, tear resistance and puncture resistance of safety protective gloves are insufficient. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing glass fiber-coated yarns for gloves, so as to solve the above-mentioned technical problems. ...
