Grain and its manufacture method.
Background technology
Air-conditioning fiber is a kind of intelligent temperature adjusting fiber, is that phase change heat storage material technology is combined out with fibre manufacturing technology
A kind of high-tech product for sending.When ambient temperature is raised, phase-change material absorbs heat to textile containing phase-change material
Amount, is changed into liquid from solid-state, reduces shell temperature.Conversely, when ambient temperature is reduced, phase-change material releases heat,
Be changed into solid-state from liquid, human body is reduced to liberated heat around, to keep normal body temperature, provided comfortably for human body
" clothing climate " environment, makes human body be in a kind of comfortable state all the time.This fiber material on one's own initiative, intelligently can be controlled
The temperature of surrounding, therefore referred to as intelligent temperature adjusting fiber.Mostly there is this fiber Double-direction Temperature to adjust and adaptability, can be in temperature
It is repeatedly circulated in vibration environment.
Due to phase-change material is all low melting point combustible material, in process, is especially being combined with matrix material
When, there is certain requirement to the temperature of matrix material.If the temperature of matrix material is too high, by phase-change material capsule somatocyst wall
Destruction, phase-change material can occur melting and even burn, and do not simply fail to process fiber, more likely cause fire incident, cause great
Loss.So, intelligent temperature adjusting fiber product currently on the market is all the materials such as viscose base, acrylon base, loycell bases, these
Fibrous matrix in process of production, substantially carrying out spinning moulding, phase-change material under room temperature or the state of temperature less than 100 DEG C
Be not in too high temperature in matrix material cohesive process, do not interfere with the form of capsule body, so as to ensure that fiber yet
Smooth molding and production., 270 or so, the cyst material of the phase transformation capsule of routine is in the temperature for the melt temperature of polyster fibre
In the case of can be carbonized, situations such as melt, shrink, rupture the cyst wall of capsule body, cause phase change material inside to leak and fire
Burn, so, still there is no the fiber product of terylene base in intelligent temperature adjusting fiber at present.
The content of the invention

Can be used for the manufacture method of the phase-change material master batch of terylene base air-conditioning fiber, it is characterised in that comprise the steps：
1）It is prepared by phase-change material capsule microgranule；2）It is prepared by phase-change material capsule.
The phase-change material capsule microgranule is prepared and is comprised the steps：1）By low melt point paraffin, high-purity activity carbon powder
Uniformly mix acquisition initial mixture with dispersant；2）By initial mixture cold drying；3）Dried mixture is melted；
4）Mixture after melting twin screw device extruding pelletization, finally gives phase-change material capsule microgranule.
The capsule is prepared and is comprised the steps：1）Polysulfonamides and DMAC are taken, by the polysulfones of 0.5-3.5% mass fractions
Amide obtains mixed solution in being dissolved in DMAC；2）The phase-change material capsule microgranule for preparing is put in mixed solution, is stood
5-30min；3）The DMAC aqueous solutions of 10-50% concentration are instilled in the solution after standing, speed 0.01-0.1m/s is instilled, now
Polysulfonamides are separated out on phase-change material surface, and form cyst wall clad；4）Separate；5）Collect；6）Cleaning；7）It is dried and obtains
Complete phase-change material capsule.
The DMAC temperature to solution instillation after standing is below 20 DEG C.
First the phase-change material capsule body for completing collecting process is moved in cleaning equipment during the cleaning, under cleaning equipment
Fang Kaiyou water inlets, with certain speed injected clear water, are provided with outlet above equipment, digging water speed is controlled in phase-change material glue
Utricule is moved slowly in cleaning equipment but movement locus are less than at the depth of water 1/2, to ensure phase-change material capsule body motion shape
