Description
Technical field
The present invention relates to field of compound material more particularly to a kind of Double-face fabric for keeping body temperature constant and its preparations
Technique.
Background technology
The most important function of clothes is to maintain blood heat, makes one body and feel comfortable.The heat transfer of clothes is basic
On can be divided into two kinds：Sensible heat transfer, i.e. human body temperature and external environment have differences producible heat transfer, it mainly passes through
Heat transfer, convection current and radiation are completed；Latent heat transfers, i.e., is generated due to the vapour concentration difference between human body and external environment
Damp and hot transmission, it is mainly completed by evaporating and perspiring.
Traditional dress mainly reaches heat preservation by controlling heat radiation, heat transfer and convection current between human body and external environment
Purpose.When the temperature of the surroundings is low, it can increase the space of the still air layer of fabric by suitably increasing fabric abundant degree
To improve warming effect；When environment temperature is close to or higher than body temperature, human body has been difficult to through radiation, convection current and conduction come dissipated heat
Amount, should reduce fabric thickness to increase the heat exchange between human body and environment, and skin also needs largely to perspire, and utilizes sweat at this time
Heat is taken away in evaporation could maintain the constant of body temperature.
With the fashion of clothes, the temperature for only maintaining human body suitable by increasing or decreasing fabric thickness is not only numb
It is tired and sometimes also highly difficult, nor it is beautiful.
As a kind of homeothermal animal, people is to maintain rational body temperature by the dynamic equilibrium of internal heat production and body surface heat dissipation
's.So-called internal heat production, the exactly energy matters such as the method by being similar to burning fuel, consumption of glucose generate heat；
And radiating then includes three kinds of heat transfer, heat convection and radiation heat transfer forms.Wherein, when human body is static, there is dissipating for 40%-60%
Heat is realized by outside infrared radiation.When the environment temperature of surrounding is less than human body temperature, human body can be warm
Amount is in the form of infrared ray to external radiation.Therefore, in the dynamic equilibrium for maintaining body temperature, if the heat of radiation is more than production in vivo
Heat, people will cool down；And if the heat of radiation is less than in vivo heat production, it can heat up.And the height of amount of radiation, mainly depend on
In " radiance ".Radiance is the build-in attribute of a body surface, and radiance is high, and the energy given off is just more；And radiance
Low, the energy taken away by heat radiation is just few.Therefore, if radiance can be controlled, it is allowed to be become higher when heat release is needed,
Need cooling when be lower, it is possible to change the external radiations heat energy of human body number, and then realize clothing help human body heat preservation
Or the regulation and control of heat dissipation.
