Description
Technical field
The present invention relates to a kind of polyacrylonitrile-based solar energy storage heat generating fiber and manufacture method thereof, belong to the fabric technology field.
Background technology
Since ancient times, habilimented " cool in summer and warm in winter " is human dream.The heat-preserving function of clothes is on traditional idea, set about from lining mostly.The heat-preserving function of lining is determined by fiber thermal conductivity and the fabric tissue of forming lining.On the one hand, the fiber thermal conductivity is relevant with the thermal conductivity factor of fiber, thermal conductivity factor is big more, warmth retention property is poor more; On the other hand, definite when fiber, the bulking intensity that can improve lining increases warmth retention property.Because the thermal conductivity factor of air has only minimum fiber thermal conductivity factor half, so still air content is many more in the lining, lining is just warming more.But it is too big when wherein space, greatly when enough causing convection current, obviously reduced the warmth retention property of lining on the contrary.This shows, if can start with, improve the hot property of fiber itself from fiber, be the basic starting point that increases the lining heat-preserving function.
According to the heating theory of fiber, absorb far infrared and near-infrared material from improving the fiber heating function, adding, thereby utilize its heat that gives off, continual heating to reach than the general fibre warming effect of more significantly generating heat.
Zirconium carbide had the efficient absorption visible light, the characteristic of reflected infrared ray after its absorbs the short wavelength's energy account in the sunshine below 95% the 2 μ m, is changed by heat, the energy can be stored in the material, also have the characteristic that reflection surpasses 2 μ m IR wavelengths simultaneously.And the infrared wave that human body produces is about about 10 μ m, so reflex to skin surface, can outwards not distribute.This explanation zirconium carbide of far-infrared ceramic particle has desirable heat absorption, the characteristic of accumulation of heat.
Far-infrared ceramic particle has the feature that the absorption far infrared can change heat into.Mix the polypropylene nitrile fiber of people's ceramic powders, can absorb the far infrared that human body is launched, simultaneously to the human body radiation far infrared.In addition, it also has the absorption sunshine, and luminous energy is converted into heat energy and stops the multiple functions such as far infrared heat release that produced on the human body.After far infrared is absorbed by the body, can make human body produce the effect that the body sense heats up.
Summary of the invention
The fiber and the manufacture method thereof that the purpose of this invention is to provide a kind of full range spectrum energy-absorbing heating.
In order to achieve the above object, technical scheme of the present invention provides a kind of polyacrylonitrile-based solar energy storage heat generating fiber, it is characterized in that, comprise acrylonitrile-methyl acrylate-methylpropene sodium sulfonate copolymer fibre, the far-infared ceramic powder and the diameter that are dispersed with diameter in described acrylonitrile-methyl acrylate-methylpropene sodium sulfonate copolymer fibre and are 0.1-4 μ m are the zirconium carbide particle of 0.01-1 μ m, and the mass ratio of described acrylonitrile-methyl acrylate-methylpropene sodium sulfonate copolymer fibre and far-infared ceramic powder and zirconium carbide particle is 100: 4-12: 0.1-1.
The present invention also provides the manufacture method of above-mentioned polyacrylonitrile-based solar energy storage heat generating fiber, it is characterized in that, concrete steps are:
The first step: acrylonitrile 82.5-90.5 weight portion, methyl acrylate 2 weight portions and methylpropene sodium sulfonate 1 weight portion graft copolymerization are obtained the copolymer magma that molecular weight is 5-8 ten thousand;
Second step: add far-infared ceramic powder and zirconium carbide particle in copolymer magma, stir 1-30min with the 1000r/min-2000r/min rotating speed, standing and defoaming is carried out wet spinning.
Advantage of the present invention is: can access the polyacrylonitrile fibre that full range spectrum is inhaled solar energy storage heat generating, this fiber has far away, near infrared endergonic function.Behind this fiber absorbs luminous energy, in clothes, work as climate change, the form that the full range energy will change heat energy into comes out, and becomes heat generating fiber.This fiber has the better spinnability energy, and fineness is 1.5-6D, powerful satisfied weaving processing request.
