Staining high-performance polyethylene fiber and high-performance polyethylene fiber,

摘要

In a wide temperature range product use and product processing temperature range, change in physical properties is small, and to provide a high-performance polyethylene fiber having excellent dimensional stability. In addition, it is possible to achieve a high dye exhaustion rate with a simple staining procedure, and, to provide a high-performance polyethylene fiber with excellent color fastness. The intrinsic viscosity [η] is the 0.8dL / g or more 4.9dL / g or less, the repeating unit is made from real ethylene, high-performance polyethylene fibers of the present invention, 0 is the maximum shrinkage stress in the (mechanical thermal analysis) TMA It is .4cN / dtex or less, and wherein the thermal shrinkage at 100 ℃ is 2.5% or less.
