Technical field
The present invention relates to intelligent temperature adjusting fiber field, specifically a kind of terylene base intelligent temperature adjusting fiber and its manufacturer
Method.
Background technique
Intelligent temperature adjusting fiber is that phase change heat storage material technology is combined to a kind of high skill developed with fibre manufacturing technology
Art product.For textile containing phase-change material when ambient temperature increases, phase-change material absorbs heat, becomes liquid from solid-state
State reduces shell temperature.On the contrary, phase-change material releases heat when ambient temperature reduces, become solid-state from liquid,
Reduce the heat that human body is released to surrounding, to keep normal body temperature, provides comfortable " clothing climate " ring for human body
Border makes human body be in a kind of comfortable state always.This fiber material can initiatively, intelligently control the temperature of surrounding, therefore
Referred to as intelligent temperature adjusting fiber.This fiber mostly has Double-direction Temperature adjusting and adaptability, can be anti-in temperature oscillation environment
It is multiple to be recycled.
What it is due to phase-change material is all low melting point combustible material, in process, especially in conjunction with basis material
When, there is certain requirement to the temperature of basis material.If the temperature of basis material is excessively high, by phase-change material capsule somatocyst wall
It destroys, phase-change material can occur melting and even burn, and do not simply fail to processing fiber, be more likely to cause fire incident, cause great
Loss.So intelligent temperature adjusting fiber product currently on the market is all the materials such as viscose base, acrylic fibers base, loycell base, phase transformation
Be not in excessively high temperature in material and basis material cohesive process, the form of capsule body influenced, to ensure that fiber
Smoothly molding and production.The melting temperature of polyester fiber is at 270 DEG C or so, and common phase-change material and its capsule are in the temperature feelings
Situations such as carbonization, melting can occur under condition, shrink, the cyst wall of capsule body is ruptured, phase change material inside is caused to leak and burn,
So the fiber product in intelligent temperature adjusting fiber still without terylene base.
