AI Technical Summary
Technical Problem
Existing polyethylene yarns for protective articles offer high cut resistance but compromise on wearability due to excessive stiffness, leading to reduced comfort and increased risk of injury.
Method used
A polyethylene yarn with a weight average molecular weight of 80,000 to 180,000 g/mol, an initial modulus of 120 to 200 g/d, and an elongation of 6 to 10%, manufactured through melt spinning, is combined with polyurethane and polyester yarns to create a covered yarn for protective articles.
Benefits of technology
The resulting protective articles exhibit a high cut resistance index of 5 or more while maintaining low stiffness, ensuring excellent wearability and reduced risk of injury.
