Title:
HIGHLY FUNCTIONAL POLYETHYLENE FIBERS, WOVEN OR KNIT FABRIC, AND CUT-RESISTANT GLOVE
Document Type and Number:
WIPO Patent Application WO/2011/049026
Kind Code:
A1
Abstract:
Provided are polyethylene fibers which can attain a high degree of exhaustion and which can be dyed in a deep color having excellent fastness. Also provided are a woven or knit fabric formed from the fibers and having excellent cut resistance and heat-insulating properties and a glove constituted of the fabric.
The polyethylene fibers are characterized by having an intrinsic viscosity [η] of 0.8-5 dL/g, excluding 5 dL/g, being composed of repeating units substantially derived from ethylene, and having pores extending inward from the fiber surface, the pores, when examined by a mercury intrusion method at a contact angle of 140º, having an average diameter of 3 nm to 1 µm in terms of approximated cylindrical shapes. The fibers are further characterized by having a porosity attributable to the pores of 1.5-20% or having a thermal conductivity at 300K in the axial direction of the fibers of 6-50 W/mK.
