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

摘要

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