Abstract
The utility model belongs to the field of functional fibers and relates to an aramid fiber attached with PCM (phase change material) phase change powder simultaneously by dyeing. The aramid fiber attached with the phase change powder by dyeing comprises an aramid fiber body, wherein the surface layer of the aramid fiber is a dye layer, and the surface layer of the dye layer is a phase change powder layer. The aramid fiber attached with the phase change powder by dyeing has the advantages of high temperature resistance, flame retardance, identity authentication effect and temperature regulation effect, and can be used in occasions easy to produce sparks and the like.
Description
Technical field
The utility model belongs to the functional fibre field, relates to a kind of aramid fiber that adds PCM phase transformation powder body material through dyeing simultaneously.
Background technology
Have in the world at present and in fibre section, mix a part of PCM phase-change material; The fiber that has certain function through spinning, moulding acquisition then; But add the fiber of PCM phase-change material through this technology; Its fiber fastness is under some influence, and the ratio of the PCM phase-change material that mixes in the fiber is also very low.
The utility model content
The purpose of the utility model provides a kind of aramid fiber through chromosome addition PCM phase transformation powder body material, and to overcome the deficiency of above-mentioned prior art, this fiber also has temperature adjustment function except that having sign discriminating effect.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme to realize:
A kind of aramid fiber through chromosome addition phase transformation powder comprises the aramid fiber body, and the top layer of said aramid fiber is a dye coating, and the top layer of said dye coating is evenly distributed with the phase transformation powder layer.
Preferable, the top layer of said dye coating is evenly distributed with phase transformation capsule powder layer.Better, the particle diameter of said phase transformation capsule powder is 2-6mu.
The aramid fiber that passes through chromosome addition phase transformation powder of the utility model adopts the polyster fibre dyeing process; When being combined with fiber, brings dyestuff a part of PCM phase transformation powder granule into; The PCM phase transformation powder of bringing into is positioned at the top layer of dye coating; Said phase transformation powder body material has the effect of heat absorption and heat release between 25 degree-30 degree, its heat content is 120 gram/joules.
The process conditions of said dyeing process do; The dyeing temperature that adopts is the 130-150 degree, and the dye cycle time is 120 minutes, and dye vat pressure is 0.3Mpa; Dyestuff adopts the cationic dyestuff of vapour Bagong department, and the particle diameter of phase transformation capsule powder is 2-6mu, phase transformation capsule powder: cation dyes: water three's weight ratio is about 3: 1: 15.
The advantage of the aramid fiber that passes through chromosome addition phase transformation powder of the utility model is:
1, the aramid fiber itself through chromosome addition phase transformation powder has high temperature resistant, fire retardation, has sign discriminating effect after the hyperchromic or dyeing, makes filtrate divide air intake surface and outlet air surface.
The sign discriminating effect of above-mentioned fiber is meant to distinguish with color dyes the application in different occasions of fiber that different colours is arranged, as, when being applied to process thickness and being the fibrofelt of 3mm; Can simultaneously be above-mentioned no color fibre, one side be above-mentioned colored fibre, when using so; Coloured one side is facing to blower fan; Dust is just at first run into coloured one side, and that coloured face is an air intake surface, and that colourless face is an outlet air surface.
2, the aramid fiber through chromosome addition phase transformation powder has thermoregulatory effect owing to have the phase transformation powder layer, need not any external energy.
3, the aramid fiber through chromosome addition phase transformation powder has high temperature resistant, fire-retardant and thermoregulatory effect, makes it can be used for the easy occasion that produces Mars etc.
4, through the aramid fiber of chromosome addition phase transformation powder, its fiber fastness can not reduce.
5, because the top layer of dye layer has the phase transformation powder, under hygrometric state, be prone to be left out, be particularly useful for high temperature dry state smoke filtration.

The specific embodiment
Further set forth the utility model below in conjunction with specific embodiment, should be understood that embodiment only be used to the utility model is described and be not used in the restriction the utility model protection domain.
Embodiment
The aramid fiber that passes through chromosome addition phase transformation powder as depicted in figs. 1 and 2 comprises aramid fiber body 1, and the top layer of said aramid fiber 1 is a dye coating 2, and the top layer of said dye coating 2 is evenly distributed with phase transformation powder layer 3.
Preferable, said phase transformation powder layer 3 is evenly distributed with the phase transformation capsule powder.Better, the particle diameter of said phase transformation capsule powder is 2-6mu.
The aramid fiber that passes through chromosome addition phase transformation powder of the utility model adopts the dyeing process of polyster fibre; When being combined with fiber, brings dyestuff a part of PCM phase transformation powder granule into; The PCM phase transformation powder of bringing into is positioned at the top layer of dye coating; Said phase transformation powder body material has the effect of heat absorption and heat release between 25 degree-30 degree, its heat content is 120 gram/joules.
Claims (3)
