Description
The present invention relates to functional fiber and goods thereof, is a kind of fiber and goods thereof with heat absorption, storage and release function specifically.This fiber or goods can be regulated self temperature by automatic bidirectional with variation of ambient temperature.International Patent classificating number intends being D01F 1/10.
Studies show that when being in thermal balance, the skin temperature of human body sensory the most comfortable is 33.4 ℃; The skin temperature at any position of health and skin MTD are in the time of 1.5～3.0 ℃, and human body sensory is neither very warm nor cold; If temperature difference surpasses ± 4.5 ℃, human body will have the changes in temperature sense.Therefore, low excessively in ambient temperature, or health is when being in relative low temperature environment overlong time, if the insulation thermal resistance deficiency of dress materials, body temperature will very fast decline, easily gives birth to flu, frostbite or other diseases.On life saving, rectal temperature is the valve limit that deep body temperature descends for 35 ℃, is lower than 35 ℃ and serious functional disturbance will occur, this moment, human body was in the subception state, lose the respond of environment to external world, when therefore being in low temperature environment, be incubated very important human body.Otherwise, in summer or the torrid zone or some particular job environment, when ambient temperature is too high, if the thermal resistance of dress materials is excessive, human body can not pass through sensible heat transfer dissipated heat as early as possible, and can only keep normal body temperatures by a large amount of perspires, keep this state for a long time, to cause that dehydration is too much in the body, the body heat regulation dysfunction causes heatstroke, even dead, when therefore being in the hot environment, in time cooling is also very important.
Traditional clothes or textiles generally by as natural fabrics such as cotton, fiber crops, silk, hair, or/and chemical fibre materials such as viscose glue, terylene, polyamide fibre, acrylic fibers composition.These fibrous materials mainly are by the heat transmission between blocking-up human body and the external environment, i.e. the effect that keeps blood heat in the clothes is played in heat radiation, heat conduction and thermal convection current.When ambient temperature is lower than the skin surface temperature of human body, have only timely increase clothes or textiles, the thermal resistance that promptly increases fibrous material reduces the heat exchange between human body and the external environment, thereby keeps the normal body temperature of human body; When ambient temperature by being lower than when changing near body temperature, must in time reduce clothes or textiles again, promptly reduce the thermal resistance of fibrous material, so that increase the heat exchange between human body and the environment.Therefore, in time suitably increasing and decreasing clothing, is to keep homoiothermal main means.But when difference variation was very big among one day, people were because subjective reason or objective condition restriction often can not be accomplished this point, particularly in the allegro modern life.When ambient temperature is higher than body temperature when (temperature is higher than body temperature in the clothes), human body can not come dissipated heat by general heat radiation, thermal convection current and heat conduction, and must be by a large amount of perspires of skin, utilize the evaporator strip of sweat to walk heat (sweat of steam state take away heat be several times as much as liquid sweat), just can keep the constant of body temperature, subtract clothing and take off also meaninglessly entirely even take off, more condition takes off too much generally speaking that to subtract clothing also be that public life institute is unallowed.Its cost is exactly that body fluid runs off too much, the total balance of the body disorder, and physique descends, and does not feel like oneself, and produces disease.
For the temperature of bettering people's living environment, people have invented various function textiles.Developed textile surface the sixties and be coated with and aluminize-the titanium alloy paper tinsel, the textiles of the far infrared that the reflection human body is launched is commonly called as " space wadding " insulation material, has obtained extensive exploitation and application the eighties at home.And for example, " Dong Lire " fiber of micro conductive material energising back heating can significantly improve heat insulation effect, contains the iron micro mist, utilizes the chemical heat release fiber of its oxidation heat liberation also to obtain exploitation abroad.The flat 3-3202 of day disclosure special permission communique discloses a kind of sunlight accumulation of heat fiber that contains the absorption near infrared ray heat release of zirconium carbide micropowder, can significantly improve the fabric temperature under the solar radiation.Chinese invention patent CN1123850A discloses a kind of the absorption and the composition and the manufacture method of emitting far-infrared fiber, can absorb the far infrared that human body launches and be converted into heat, the raising heat insulation effect.Disclose the fiber of heat radiation in a kind of reflected sunlight, shielding ultraviolet rays among the flat 5-117910 of day disclosure special permission communique, its fabric can reduce internal temperature.But all these fibrous material textiless all only have unidirectional temp regulating function, promptly can only improve heat insulation effect, or reduce to a certain extent and obey interior temperature, and can not both can improve the heat insulation function of fibrous material, can reduce fibrous material thermal resistance effect again, particularly can not improve or reduce the insulation effect of fibrous material according to the human body needs, promptly not have bidirectional temp regulation function or effect.
Textiles with bidirectional temp regulation function is the eighties, particularly the new problem of world's fibrous material research nineties.Disclose as United States Patent (USP) 4871615 and a kind of inorganic hydrated salt or the plastic crystal material method by dipping to be filled in doughnut inside, preparation has the method for temp regulating function fiber, wash but this fiber is neither water-fast, do not have durability yet, the crystallization water in the hydrated salt can evaporate in the heating-cooling process, makes fiber lose the adjustment effect.For another example, applicant's Chinese invention patent ZL96105229.5 discloses a kind of principal component that adopts polymer such as polyethers, aliphatic polyester, polyester ether as the core or the island component of fiber, with the fibre-forming polymer is sheath composition or sea component, produces the method with automatic temperature-control functional fibre through melt composite spinning.But it is the fiber manufacturing of core or island component that this method only is applicable to polymer, for the lower organic matter of melt viscosity, then be not suitable for as positive dodecoic acid, positive tridecanol, positive tetradecyl alchohol, positive pentadecanol, positive hexadecanol, hexadecane, n-heptadecane, n-octadecane, NSC 77136, n-eicosane, Heneicosane, n-docosane etc., because these organic matters can be in spinning process, from the sheath of fiber or sea component, overflow, make spinning process be difficult to carry out.
The purpose of this invention is to provide a kind of autoamtic temp-regulating fibre and goods made from the accumulation of heat microcapsules technology thereof.It can adopt the organic matter phase change material as functional additive, and can adopt general spinning and textile technology to manufacture, and has the better function of heat absorption automatically, storage and heat release according to variation of ambient temperature.
The maximum characteristics that fiber of the present invention and goods thereof are different from conventional fibre and goods thereof are when environment temperature is higher, but the heat of absorbing environmental and be stored in fibrous inside makes the fibrous inside temperature be lower than conventional fibre; And when environment temperature is low, energy stored in the fiber can be discharged again, make the fibrous inside temperature be higher than conventional fibre.The automatic temperature-adjusting regulating action of fiber of the present invention has than the better wearing comfort of business suit the clothes that adopt this fiber process to become; When being used for house decorative material, the fluctuations in indoor temperature scope is reduced relatively, build the environment of people's live and work preferably.
The object of the present invention is achieved like this: design a kind of autoamtic temp-regulating fibre with heat absorption automatically, storage and heat release function according to variation of ambient temperature, it is characterized in that described autoamtic temp-regulating fibre is is functional adding ingredient with the accumulation of heat microcapsules, fibre-forming polymer with routine is a base material, the weight ratio of accumulation of heat microcapsules and fibre-forming polymer is 30～80: 70～20, adopts conventional spinning technique to make; Described accumulation of heat microcapsules are meant that with melt temperature be 20～50 ℃, and crystallization temperature is 30～5 ℃, and the phase change material of melting heat and crystallization heat 〉=200J/g is a capsule-core, and phase change material weight should account for 40～80% of accumulation of heat microcapsules gross weight; With styrene-divinylbenzene copolymer, Melamine, Lauxite, epoxy resin or calcium silicates is cyst wall, adopts situ aggregation method synthetic; Described accumulation of heat microcapsule diameter is 0.1～20 μ m.
Autoamtic temp-regulating fibre of the present invention compared with prior art is to have designed advanced accumulation of heat microcapsules technology, and use organic matter, rather than polymer is as phase change material, make raw material sources more extensive, and because organic matter has the bigger heat of transformation than the polymer that uses in the prior art, so better by its fiber made and the automatic regulatory function of temperature of articles thereof.In addition, the present invention can adopt general spinning technique to manufacture, and the complicated composite algorithm spinning technique that does not adopt prior art to use makes production more simple.
It is to utilize the accumulation of heat microcapsules to make the technology of autoamtic temp-regulating fibre that the present invention designs principal character.It adopts with melt temperature is 20～50 ℃, and crystallization temperature is 30～5 ℃, and the phase change material of melting heat and crystallization heat 〉=200J/g is a capsule-core, and phase change material weight should account for 40～80% of accumulation of heat microcapsules gross weight; With styrene-divinylbenzene copolymer, Melamine, Lauxite, epoxy resin or calcium silicates is cyst wall, adopts situ aggregation method synthetic.And described accumulation of heat microcapsule diameter should be controlled between 0.1～20 μ m.After this accumulation of heat microcapsules are made autoamtic temp-regulating fibre and goods thereof with suitable manner, the fiber and the goods thereof that contain above-mentioned accumulation of heat microcapsules just can be when environment temperature be higher than the melt temperature of phase change material, heat in the absorbing environmental, make the phase change material in the accumulation of heat microcapsules change liquid into from solid gradually, heat is stored; When environment temperature was lower than the crystallization temperature of phase change material, the phase change material in the accumulation of heat microcapsules was converted into solid from liquid again gradually, emitted stored heat, thereby reached the purpose of automatic adjusting temperature.So-called autoamtic temp-regulating fibre and goods thereof just are meant according to the variation of environment temperature neither endothermic nor exothermic automatically, and oneself moves the fiber and the goods thereof of bidirectional modulation to environment temperature.
It is 20～50 ℃ that phase change material (PCM) in the accumulation of heat microcapsules of the present invention should adopt melt temperature, and crystallization temperature is 30～5 ℃, and the phase change material of melting heat and crystallization heat 〉=200J/g is a capsule-core.This is to consider autoamtic temp-regulating fibre and goods environment for use, purposes and performance need, specifically selects for realizing that the object of the invention is required in other words conj.or perhaps.The content of described PCM should account for 40～80% of capsule gross weight; Be 50～80% better.Phase change material content is lower than 40%, and suction, the thermal discharge of accumulation of heat microcapsules are less, are difficult to satisfy practical requirement.Repeatedly repeat result of study and show that the content of phase change material can reach about 80%.As continue to increase the content of phase change material, and then can make cyst wall intensity low excessively, be prone to leakage phenomenon in the use, influence the stable of fibre property and inhale the effect of heat release function.
Phase change material as capsule-core of the present invention is one or more in positive dodecoic acid, positive tridecanol, positive tetradecyl alchohol, positive pentadecanol, positive hexadecanol, hexadecane, n-heptadecane, n-octadecane, NSC 77136, n-eicosane, Heneicosane, the n-docosane; Described cyst wall is a kind of in styrene-divinylbenzene copolymer, melamine, Lauxite, epoxy resin or the calcium silicates.
The present invention adopts organic matter to compare as phase change material with the employing polymer of prior art as phase change material, have alternative widely, and these organic suctions, thermal discharge are bigger than suction, the thermal discharge of the polyethers that uses in the prior art, aliphatic polyester, polyester ether, as method when test of adopting differential thermal analysis, the phase transition temperature of several typical organic matters and polymer and the heat of transformation such as table 1.

The present invention was in order to prevent heat fusing or to cross the cold crystallization phenomenon, also contained crossing heat fusing and cross cold crystallization and preventing agent of phase change material weight 1～10% in the core materials.Described cross heat fusing and cross cold crystallization prevent that agent from being at least a in the melt temperature organic acid higher 10～30 ℃ than described phase change material melt temperature, organic alcohol or the organic ester; Described organic acid is meant n-octadecanoic acid, positive nonadecanoic acid, positive 20 acid, positive heneicosoic acid, oleic acid, linoleic acid; Described organic alcohol is make a comment or criticism nonadecanol, positive eicosanol; Described organic ester is meant n-octadecanoic acid methyl esters, ethyl linoleate.
The present invention is functional adding ingredient with above-mentioned accumulation of heat microcapsules, fibre-forming polymer with routine is a base material, with weight ratio is that 30～80: 70～20 accumulation of heat microcapsules and fibre-forming polymer melt or solution mix, adopt conventional or approximate conventional fusion or solvent spinning technology, promptly can be made into the autoamtic temp-regulating fibre of the present invention that contains the accumulation of heat microcapsules.Test shows that this autoamtic temp-regulating fibre has the better spinnability energy, adopts common weaving (containing knitting, non-woven) technology promptly to can be made into various autoamtic temp-regulating fibre goods.
The present invention requires the percentage by weight of the accumulation of heat microcapsules in the described fiber to be controlled between 30～80%.Accumulation of heat microcapsules percentage by weight in the fiber is lower than at 30% o'clock, then the phase change material that contains in the fiber very little, heat absorption and store the effect not obvious; And surpass at 80% o'clock, and fiberizing difficulty then, or the fibrous physics mechanical performance after the moulding is relatively poor, does not have textile processibility preferably.But this accumulation of heat microcapsules percentage by weight of not getting rid of in the fiber is higher than suitable the present invention in 80% o'clock.Because under certain condition, for example with fiber manufacturing of the present invention to material mechanical physics or say that textile processibility can less demanding air cleaning or during the function filter material, the accumulation of heat microcapsules percentage by weight in the fiber also can be higher than 80%.
Why the present invention limits the diameter of accumulation of heat microcapsules between the scope of 0.1～20 μ m, mainly is based on the consideration of autoamtic temp-regulating fibre production technology aspect.When accumulation of heat microcapsule diameter during greater than 20 μ m, stop up screen pack or spinneret orifice in the spinning process easily, or cause fracture of wire, make the fiber process difficulty, so the accumulation of heat microcapsule diameter is unsuitable excessive; But the accumulation of heat microcapsule diameter is also unsuitable too small, when its diameter during less than 0.1 μ m, occurs bonding between the accumulation of heat microcapsules easily, is unfavorable for the even dispersion of accumulation of heat microcapsules in polymer, and the synthetic difficulty of the microcapsules of accumulation of heat simultaneously also strengthens, and cost will significantly rise.When usually the accumulation of heat microcapsule diameter is controlled between 0.5～10 μ m, then above-mentioned problem can not occur, and the automatic temperature-control of accumulation of heat microcapsules is even, stable, effect is better.
