Background technology
A kind of air-conditioning fiber, that is, intelligent temperature adjusting fiber is to be combined out phase change heat storage material technology with fibre manufacturing technology
A kind of high-tech product sent out.For textile containing phase-change material when ambient temperature increases, phase-change material absorbs heat
Amount, becomes liquid from solid-state, reduces shell temperature.On the contrary, when ambient temperature reduces, phase-change material releases heat,
Become solid-state from liquid, reduce the heat that human body is released to surrounding, to keep normal body temperature, is provided comfortably for human body
" clothing climate " environment makes human body be in a kind of comfortable state always.This fiber material initiatively, can be controlled intelligently
The temperature of surrounding, therefore referred to as intelligent temperature adjusting fiber.This fiber mostly has Double-direction Temperature adjusting and adaptability, can be in temperature
It is repeatedly circulated in oscillation environment.
What it is due to phase-change material is all that low melting point combustible material is especially combined with basis material in process
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 bases, these
Fibrous matrix in process of production, carries out spinning moulding, phase-change material under the state of temperature substantially with room temperature or less than 100 DEG C
Be not in excessively high temperature in basis material cohesive process, the form of capsule body will not be influenced, to ensure that fiber
It is smooth molding and production.The melting temperature of polyester fiber is 270 or so, and the cyst material of conventional phase transformation capsule is in the temperature
In the case of can occur carbonization, melting, shrink situations such as, so that the cyst wall of capsule body is ruptured, phase change material inside caused to leak and fire
It burns, so, the current fiber product still without terylene base in intelligent temperature adjusting fiber.
