Description
Technical field
The present invention relates to a kind of blended yarn and production method thereof, specifically a kind of phase-changing and temperature-regulating blended yarn and production technology thereof with temperature adjustment function belongs to the weaving production technical field.
Background technology
Phase-change material PCM (phase change materials) is that a kind of material phase of utilizing changes the chemical material that carries out energy storage and exoergic.Since the thirties in 20th century; particularly be subjected to the impact of the energy crisis eighties, the basic theory of phase-change thermal storage (LTES) and application technical research emerge rapidly and obtain development in European and American developed countries (such as the U.S., Britain, Canada, Japan, Germany etc.).The fast development that interpenetrates with science and technology in the fields such as material science, solar energy, space technology and Engineering Thermophysics is that condition has been created in phase-change thermal storage research and application, and phase-change material is in the application in textile garment field, particularly also more and more extensive in the application that has aspect the temperature adjustment function textiles, also more and more deep to the research of this respect.At present, the phase-changing and temperature-regulating fabric is widely used in outdoor clothes, underwear, sweater, shirt, cap, gloves and bedding etc.
Early 1970s, Hansen.R.H is dissolved into the gas of CO2 and so on first in the various solvents, utilizes specific process that hollow space is sealed, make the fiber hollow space the gas generation solution-airs such as CO2 (Gu) change mutually, reach the purpose of insulation with this.But be only applicable to the lower situation of temperature, and gas is easy to overflow in the process of fabric processing, makes fabric lose temperature adjustment function from fiber.
Phase early 1980s, the people such as Vigo in laboratory, United States Department of Agriculture south will be filled into the inorganic salts (sodium sulphate, calcium chloride, strontium chloride etc.) of the crystallization water hollow space of doughnut, the purpose of utilizing melting that the phase transformation hydrated salt at room temperature occurs and crystallization to reach heat absorption and release, thus temperature regulated.But the inorganic salts of inside hollow fibre have the heat release of suction function in when beginning, but repeatedly after the heating and cooling, inorganic salts just lose the crystallization water and separate out from fiber.Afterwards, the people such as Vigo also with the crystallizable polyethylene glycol envelope of normal temperature people inside hollow fibre, after this fiber circulates through 150 heating and cooling, still had the heat release of suction function.But because the diameter of doughnut is thicker, be difficult to avoid fiber surface to speckle with polyethylene glycol, so the promotional value of industrialization is also very little.
20th century the mid-80, TRDC (triangle research ﹠amp; Development company) company is sealed in phase-change material in the microcapsules, develops to have the microcapsules of inhaling the heat release function.The people such as contemporaneity Vigo make the homogeneous aqueous solution after the crosslinking agents such as the polyethylene glycol of 500-8000 and DMDHEU and catalyst are mixed together, again cotton, polyester-cotton blend and wool fabric etc. are flooded in solution, roll press for extracting juice, dry, soap, about 50% the fabric that obtains increasing weight, test finds that this kind fabric has obvious suction exothermal effect in 0-50 ℃ of scope.
The beginning of the nineties, Japan ester company adopts spin processes directly low temperature phase change material such as paraffin to be spinned at fibrous inside, and carries out epoxy resin at fiber surface and process, and this fiber is in heating and cooling process, paraffin melting heat absorption, crystallization heat release make this fiber have the effect of heat absorption, heat release.
U.S. TRDC company was in the microcapsules of 1.0～10.0 μ m by the paraffin class hydrocarbon is sealed people's diameter in 1993, then make the fiber with reversible accumulation of heat characteristics with the polymer solution spinning, also there is company to add phase-change microcapsule to fabric face by the mode of coating, improves the heat insulating ability of fabric with this.
During the Gulf War, the development of U.S. TRDC company has the jacket (PECS) of long-acting cooling function.The researcher is sealed in the various pockets by the small phase-change material with diameter 3～100 μ m and is fixed on the jacket, has obtained significantly temperature-regulation garment of Process of absorption or liberation of heat dose-effect fruit.The PECS clothes of lightweight can make in the clothes temperature remain on 26 ℃ to reach 2-3h, and reinforced PECS clothes can make in the clothes temperature remain on 26 ℃ to reach 3h.
1998, U.S. TRDC company will carry out the fusion method Spinning through the microcapsules of modification, make the polypropylene fiber that contains 3% (weight) phase-change material micro-capsule, and fiber is tested, and the result shows that this fiber has the adjustment ability.
China begins the research work of heat-accumulation temperature-adjustment textiles from early 1990s, functional fibre research institute of Tianjin University of Technology took to the research and development of thermo-regulated fiber from 1993, make the fiber with temp regulating function and carried out series of studies carry out melt composite spinning take polyethylene terephthalate one polyethyleneglycol block copolymer, aliphatic polyester, polyethylene glycol and polytetramethylene glycol as raw material.The horse twilight associate professor of College of Material Chemical Engineering, Tianjin Polytechnic Univ. adds phase-change material polyethylene glycol (PEG) on the fabric to crosslinking method, and the heat-accumulation temperature-adjustment performance of fabric after the arrangement is studied.
1997, Tianjin University of Technology conducted in-depth research the melt composite spinning technology, had developed phase change material content more than 16%, and monofilament linear density is the thermo-regulated fiber of 5dtex.2000, Tianjin University of Technology is evenly mixed a certain amount of temperature adjustment microcapsules with adhesive, defoamer, carry out top finish in textile and wash/COTTON FABRIC, its heat of transformation can reach 40J/g after measured, thermal resistance value is also brought up to 0.245CLO from original 0.207CLO, but gas permeability descends after arrangement, and physical and mechanical properties is also influenced.Phase-change material micro-capsule content has reached 20Wt% in the melt-spun fibre of the Zhang Xingxiang of Tianjin University of Technology development, can keep after tested the inner temperature to be lower than 30 ℃ under 38 ℃ temperature and reach 25h, has tried out at present in my military flying suit and ventilation clothing etc.
2003, the Medical cooling clothing of equality people development in the third of the twelve Earthly Branches was opened by Tsing-Hua University, and by making a plurality of pockets for the dress cooling bag on the clothes, and each pocket has sealing.During use cooling bag packed in the pocket of cooling clothes, utilize latent heat of phase change to lower the temperature.
The phase-changing and temperature-regulating fiber can purely spin, also can with all kinds of fiber blends such as cotton, cashmere, mulberry silk, polyvinyl, terylene; Both can be woven, also can be knitting.At present, the phase-changing and temperature-regulating fiber adopts and mostly adopts two kinds of fiber blends is main, less to the research of tricomponent fibre blending.The phase-changing and temperature-regulating fabric mostly adopts coating and implants form in the corpus fibrosum, yet coated fabric is not water-fastness, easily drops, and fabric is thick and heavy sultry, wiriness, and gas permeability is poor, is unfavorable for that human body wears for a long time; The phase-changing and temperature-regulating fiber is the Outlast fiber take acrylic fibers as matrix again, and its cross section is thicker, and is larger than resistance, and cohesive force is poor, and electrostatic phenomenon can appear in spinning process, and these characteristics have had a strong impact on carrying out smoothly of spinning processing.
