Title:
HIGHLY FUNCTIONAL POLYETHYLENE FIBER, AND DYED HIGHLY FUNCTIONAL POLYETHYLENE FIBER
Document Type and Number:
WIPO Patent Application WO/2012/117596
Kind Code:
A1
Abstract:
Provided is a highly functional polyethylene fiber which is small in changes of physical properties and has excellent dimensional stability over a wide range of product processing temperature and a wide range of product's service temperature. Also provided is a highly functional polyethylene fiber which is capable of achieving a high dye exhaustion ratio by a simple dyeing operation and has excellent color fastness. The highly functional polyethylene fibers of the present invention are characterized by having a limiting viscosity [η] of 0.8 dL/g to 4.9 dL/g (inclusive), a repeating unit that is substantially composed of ethylene, a maximum contraction stress as determined by TMA (thermomechanical analysis) of 0.4 cN/dtex or less and a thermal shrinkage at 100˚C of 2.5% or less.
