Description
Technical field
The present invention relates to a kind of polyester stretch textured yarn and preparation method thereof, particularly to a kind of acquisition, there is efficient selective nano-zirconium carbide polyester stretch textured yarn of the heat storing and heat preserving functional characteristic of sensing automatically absorbing visible ray, reflection infrared ray and reflection thermal radiation of body thermal source and preparation method thereof, belong to new function fibre in differentiation field of material technology.
Background technology
Traditional still air layer being incubated between the heat insulating material formed thickness depending on fabric and density and increased fiber and reduce conduction of heat and the thermal convection current of clothing, reach the purpose that conventional vacuum is warming, but thickness is crossed conference and is caused clothing entirety more too fat to move, is not easy to move and lack aesthetic feeling.Along with people are to beautiful pursuit, this passive warming mode of insulation can't fully meet people and the slim and graceful of water clothes is incubated heat-preserving function and the requirement of aesthetic property.
At present, on market, the insulation for textile field of Development and Production is heat insulating material formed mainly has doughnut, superfine fibre, phase transformation heat preservation heat insulating material formed and far infrared thermal insulation is heat insulating material formed etc., the ultimate principle that conventional vacuum is heat insulating material formed followed by these materials, utilize conduction of heat and thermal convection current or heat radiation mechanism or absorb heat by external environment condition or heat release function and reach to be incubated warming purpose, but, its heat-absorbing energy-accumulating, the heat release warming effect of insulation are not ideal.Therefore, research and development new function, intelligent, the heat-absorbing energy-accumulating of environment-friendly type, the emphasis of the heat release heat insulating material formed warming insulation fibre investigation of materials having become textile field of insulation.
To obtaining higher effect, there is maximum heat-absorbing energy-accumulating, the research of the nano-zirconium carbide material (ZrC) of heat release insulation heat-preserving function finds, nano-zirconium carbide material has higher far infrared transmissivity than simple metal or nonmetallic materials, there is more preferable conduction of heat and thermal convection current and thermal radiation property, especially nano-zirconium carbide material have efficient absorption sunlight medium wave a length of 0.1～2.0 um far infrared gross energy more than 95% ability and absorb far infrared transmissivity reach more than 87%, 92% is can reach under specific condition, the most also can reflect greater than the 2.0 ultrared functions of um wavelength, i.e. reflect the near infrared ray (4～14 um) of human body radiation.Therefore, nano-zirconium carbide is a kind of to have preferably far and near infrared ray and the novel high function of visible absorption performance, intelligent, the material of environment-friendly type, the nano-zirconium carbide polyester preoriented yarn prepared with this nano-zirconium carbide material possesses bidirectional inductive heat-absorbing energy-accumulating, effect of heat release insulation heat-preserving function, has good Prospects of Sustainable Development.
Before the present invention makes, Chinese invention patent (CN103132177A) discloses a kind of nano-zirconium carbide sensing type heat-storage heat-preservation polyester fiber and preparation method thereof.With nano-zirconium carbide as additive, online interpolation mass fraction 1.0～8.0%, melt with polyester slice homogeneous blend in screw rod, blend melt is extruded from spinneret micropore, cooled solidified forming and oil nozzle oil boundling technique, make POY silk cylinder with winding speed 3000m/min～3200m/min winding, after balance, it is draw textured again, prepares nano-zirconium carbide sensing type heat-storage heat-preservation polyester fiber.The mass fraction of the nano-zirconium carbide owing to being added is only 1.0～8.0%, therefore, the fiber prepared heat release be incubated warming and bidirectional inductive heat-absorbing energy-accumulating function aspects less effective, especially ambient temperature the lowest or extremely low in the case of also do not reach human body insulation heat-preserving function requirement；nullSimultaneously，Due also in this technology，The nano-zirconium carbide additive added in spinning process is that nano-particle state is present in melt or fiber surface，In making POY silk and the stretcher strain course of processing，Fiber needs the contact on stretcher strain appliance arrangement surface just can be draw textured，Owing to the technology of FDY one step method is to use hot-rolling stretching process，Especially prepare and the spinning process of POY silk uses the biggest conventional draw-off godet reel system device，Coefficient of friction between its tow and the biggest draw-off godet reel system device and frictional resistance and tensile stress are bigger，Cause strand tensile tension force bigger，Uniform and stable property is poor，When the POY silk that with the addition of nano-zirconium carbide is draw textured on stretcher strain appliance arrangement surface，Coefficient of friction、Frictional resistance and stretcher strain warp tension ratio are not added with the tow of nano-zirconium carbide and increased，When the mass fraction of the nano-zirconium carbide added is more than 8.0% spinning carried out above，Lousiness broken end in the course of processing will be caused many，The uniform and stable property causing POY silk product quality is poor，The after-drawing deformation performance deterioration of the POY silk made，Production is even made to be normally carried out.Therefore, using existing production technology, the mass fraction of the nano-zirconium carbide added must be limited in less than 8.0%, and guarantee produces and is normally carried out, it is thus achieved that preferably product quality.For above-mentioned reasons, prior art cannot provide good product quality, and has high effect, the polyester fiber of bidirectional inductive accumulation of energy heat release insulation heat-preserving function characteristic.
