Description

A kind of abnormity thermal polyester fibers and preparation method thereof
Technical field
The invention belongs to functional fibre material fields, and in particular to a kind of abnormity heat generating fiber and preparation method thereof.
Background technique
In recent years, the heat generating fiber developed both at home and abroad is mainly based on far IR fibre.By absorbing human body hair The heat of injection can make body local generate thermogenetic effect to the far infrared of one wavelength range of human body radiation.But by The thermal insulation property of the thermal Finite caused by human body, such fabric is also limited, improves compared with business suit less than 1 ℃.Therefore, luminous energy heat generating fiber material has become a hot topic of research.
Infrared spectroscopy is usually divided into three regions: near infrared region (0.75~2.5 μm), middle infrared according to optical wavelength (2.5~25 μm) and far-infrared band (25~300 μm).Infrared ray absorbing mechanism is Spectral matching RESONANCE ABSORPTION, that is, works as radiation source Radiation wavelength it is consistent with the absorbing wavelength of radiant matter when, which just absorbs a large amount of infra-red radiation.Human body is a kind of natural Infrared ray emission source, regardless of the colour of skin, the emissivity of skin of living body is 98%, and the heat radiation wavelength of human body surface is 2.5 ~15 μ ms, peak wavelength is about at 9.37 μm, wherein the radiation of 8~14 mu m wavebands is about human body total radiation energy 46%, while human body is good infrared absorber again, absorbing wavelength is based on 8~14 μm, the heat of human-body emitting and absorption Infrared band range in radiation mainly.The wavelength band for the solar radiation observed on the ground is about 0.295~2.5 μm, Belong to visible light and near infrared band range more.Luminous energy heat generating fiber be a kind of visible light in absorbable solar radiation with it is close red Outside line, and thermal radiation of body can be reflected, mainly to add based on IV group 4 transition metal carbide, such as ZrC, TiC, HfC, it is domestic Have using tourmaline powder and (or) bamboo-carbon powder.Day Bender mountain, which all goes out with You Nijika company joint research and development, contains zirconium carbide (ZrC), it can absorb the heat accumulation thermal fiber " solar- α " of solar energy.It is a kind of core-skin composite fiber, and sandwich layer is containing zirconium carbide Polyamide or polyester, cortex be common fiber-forming polymer, formed by double screw extruder melt spinning.This fiber process at After clothes, temperature can be 2~8 DEG C high compared with business suit in the lower clothes of sunlight irradiation.Asahi Kasei Corporation uses double-layer structure, and outer layer uses For sunlight heat-storing material to improve body-sensing temperature rise effect, internal layer can reflect thermal radiation of body using mixing far-infrared ceramic material, with Reduce thermal loss caused by human-body radiating.Tourmaline far infrared transmissivity with higher, but for sunlight and human body radiation Absorption heating effect it is poor.Bamboo-carbon powder usually has preferable suction-operated, does not have after absorbing sunlight or human body radiation The effect of fever.If Chinese patent discloses (bulletin) number: CN104389043A, disclose a kind of using tourmaline powder and bamboo charcoal Powder, the warming heat generating fiber of production tubular filament, does not have moisture absorption sweat discharging functions.
Chinese patent 201610506518.1 provides a kind of spontaneous heating polyester fiber and preparation method thereof, and feature exists In: by Direct-spinning of PET Fiber fever auxiliary agent, polyester fiber, Direct-spinning of PET Fiber is prepared with master batch；The Direct-spinning of PET Fiber is helped with fever Agent by weight percentage, including inorganic fever powder 0.5-10%, cure-crosslinking agent 1-20%, diluent 70-98.5%.System The method for obtaining the spontaneous heating polyester fiber is that diluent, which is uniformly mixed, obtains polyester spinning by inorganic fever powder, cure-crosslinking agent Silk fever auxiliary agent；Then Direct-spinning of PET Fiber is put into melt spinning machine with master batch and carries out melt spinning and obtain polyester precursor, will gathered Ester spinning is sprayed at polyester filament surfaces with fever auxiliary agent and carries out drawing-off winding, stretching, sizing, obtains spontaneous heating polyester fiber. This spontaneous heating polyester fiber has significant heating effect and low in cost, and manufacture craft is simple.The invention is non-using in situ Polymerization is will generate heat auxiliary agent spraying, bonding, solidification in fiber surface, and does not have odd-shaped cross section and moisture absorption sweat discharging functions.
Chinese patent 201110277437.6 provides a kind of preparation method of high comfortable composite functional polyester fiber, packet An esterification reaction section, secondary esterification reaction section, polymerization reaction process and spinning process are included, is drawn in an esterification reaction section Enter aliphatic dicarboxylic acid and/or non-contraposition aryl dicarboxylic acid as Third monomer；It is introduced in secondary esterification reaction section soft Property polyethylene glycol is as the 4th monomer；After the completion of esterification, addition is the hindered amines of solvent allotment with acetic acid and ethylene glycol respectively Light stabilizer and Hinered phenols antioxidant and hydroxy silicon oil；After the prepolymerization of polymerization reaction process terminates, final polymerization it Before, ultraviolet absorbing agent and antistatic agent is added.Before spinning process, pre-crystallized and drying is carried out to polyester slice, through molten Melt three leaves of spinning, cross, the profiled fibres such as five leaves, gained polyester fiber has excellent uvioresistant, antistatic, anti-ageing Change, anti pilling and absorbing fast-drying performance, fabric have high-comfort.Its fiber and fabric do not have the function of energy storage heat generating Energy.
Chinese patent CN104213242A provides a kind of extinction heating function fiber and its spinning processing technology and face Material can solve existing thermal isolation and heat storage functional fiber or the poor problem of fabric heat absorption efficiency, and also be not required to after its weaving It to be dyed again, so as to achieve energy-saving and emission reduction purposes.Its function essentially consists in extinction fever, for thermal radiation of body Absorption, fever and the effect kept the temperature then have no and do not have odd-shaped cross section and moisture absorption sweat discharging functions.
It follows that existing heat generating fiber material causes heating property different since the functional powder of use is different Cause, or can only extinction fever, do not have while can absorb the function of solar radiation, thermal radiation of body and infrared emanation, or Only take into account the heating effect or heat generating and retention effect of fiber.Meanwhile existing thermal polyester fibers are inhaled due to lacking hydrophilic radical Wet ability is poor, and temperature easily causes wet, bored air-locked feeling when increasing, and influences the comfort of dress.
