Description
Technical field
The utility model discloses a kind of Intelligent heat-accumulating memory fibers.
Background technique
When people work in the high temperature environment, although the sun protection clothing of dress, thermal protective clothing can be obstructed effectively in environment and be radiated
The entrance of heat, high temperature heat, but the intensive work of long-time moderate strength or short time can increase the activity of muscle group,
Basic metabolism speed is improved, accelerates blood circulation, palpitates quickly, skin temperature obviously rises, these protective garments are equally also
The heat loss of body generation is limited, causes microenvironment temperature and humidity under protective garment to increase, makes the heat of human skin surface not
Disconnected accumulation, causes Studies of Human Body Heat dysequilibrium, eventually leads to human body and generates nausea and vomiting, body temperature rising, absent minded etc. instead
It answers, brings serious harm to body.Comfort when how hot environment to be kept to work is one of research contents of people.Mesh
Preceding research more is exactly thermo-regulated fiber, the main phase change material by containing in fiber, occur to the cold, after heated admittedly-
Liquid reversible transition and absorb, release heat, thus with temp regulating function novel intelligent fiber.In certain temperature range
Interior, intelligent temperature adjusting fiber can absorb according to the variation of ambient temperature or release heat, to carry out Double-direction Temperature adjusting, In
Substantially invariable moist heat is formed around textile.When environment temperature increases, intelligent temperature-regulation fabric can absorb heat
Amount, and when environment temperature reduces, then heat can be released, to reduce the fluctuation of skin surface temperature, meets people well
Requirement to wearing comfort.Existing thermo-regulated fiber phase-change material content is lower, and the heat of absorption is less, works as absorption
Heat reach capacity after.If temperature continue to increase or fiber encounter flame after be likely to cause to burn, people will be given
Body bring serious burn, in order to avoid fabric burning to bring the injury of people as far as possible, this just proposes textile fabric
New requirement.
Summary of the invention
A kind of Intelligent heat-accumulating memory fiber, the fiber are skin-core structure, and crust is viscose rayon, are contained inside the crust
There is phase-change microcapsule, inner core is memory textured fibre, and the memory textured fibre longitudinal direction original shape is helicoidal structure, through drawing
It is stretched into as linear structure, this linear state is kept after external force removal, the cross section of the memory textured fibre is pentagon knot
Structure.When the temperature of memory fiber is more than 80~100 DEG C, memory textured fibre is just reverted to initial spiral knot by linear structure
Structure, and since the effect textile fabric of contraction starts to reduce the burn to human skin far from human body surface.
Further, in the above-mentioned technical solutions, the crust exterior contour is sexfoil, this section can be with increased fiber
Specific surface area, so that the phase-change microcapsule included is adequately contacted outside heat, when phase-change microcapsule absorbs enough heats,
After the complete phase transformation of phase-change material, fiber temperature starts to increase, and memory textured fibre takes place effect and generates deformation, far from people
Body reduces burn or scald to human body.
Further, in the above-mentioned technical solutions, the mass ratio of core-skin is 1.5~2:1.
Further, in the above-mentioned technical solutions, include containing the inside inside the crust 10~25% the micro- glue of phase transformation
Capsule.
Detailed description of the invention
Fig. 1 is the utility model Intelligent heat-accumulating memory fiber cross-sectional view；
In figure, 1 phase-change microcapsule, 2 viscose rayons, 3 memory textured fibres.
Specific embodiment
Following nonlimiting examples can make those skilled in the art that the utility model be more fully understood, but
The utility model is not limited in any way.
Embodiment 1
A kind of Intelligent heat-accumulating memory fiber, the fiber are skin-core structure, and crust is viscose rayon 2, inside the crust
Containing phase-change microcapsule 1, inner core is memory textured fibre 3, and the longitudinal original shape of the memory textured fibre 3 is helical form knot
Structure, drawn become linear structure, this linear state are kept after external force removal, the cross section of the memory textured fibre is five
Angular structure.When the temperature for remembering textured fibre is more than 80~100 DEG C, memory textured fibre is just reverted to just by linear structure
The helical structure of beginning, and since the effect textile fabric of contraction starts to reduce the burn to human skin far from human body surface.
The crust exterior contour is sexfoil, this section can keep the phase transformation included micro- with the specific surface area of increased fiber
Capsule can adequately contact outside heat, when phase-change microcapsule absorbs enough heats, after the complete phase transformation of phase-change material, fiber temperature
Degree starts to increase, and memory textured fibre takes place effect and generates deformation, far from human body, reduces burn or scald to human body.
Embodiment 2
A kind of Intelligent heat-accumulating memory fiber, the fiber are skin-core structure, and crust is viscose rayon 2, inside the crust
Containing phase-change microcapsule 1, inner core is memory textured fibre 3, and the longitudinal original shape of the memory textured fibre 3 is helical form knot
Structure, drawn become linear structure, this linear state are kept after external force removal, the cross section of the memory textured fibre is five
Angular structure.When the temperature of memory fiber is more than 80~100 DEG C, memory textured fibre is just reverted to by linear structure initial
Helical structure, and since the effect textile fabric of contraction starts to reduce the burn to human skin far from human body surface.
The crust exterior contour is sexfoil, this section can keep the phase transformation included micro- with the specific surface area of increased fiber
Capsule can adequately contact outside heat, when phase-change microcapsule absorbs enough heats, after the complete phase transformation of phase-change material, fiber temperature
Degree starts to increase, and memory textured fibre takes place effect and generates deformation, far from human body, reduces burn or scald to human body.
The mass ratio of core-skin is 1.5~2:1.It include 10~25% phase-change microcapsule containing the inside inside the crust.
