Abstract
The intelligent temperature adjustment textile hydrolyae and polymerize the ethyl-orthosilicate, the absolute ethyl alcohol and the distilled water silicon dioxide network structure gelatin in normal temperature. Then joins the alcohol type changeing material to make bonds change material. Finally mix the bonds change material and bond then spread on the textile's surface. This invention's intelligent temperature adjustment textile is insert change material into the high thermal conductive silicon dioxide's network gelation to make nanometer even micronanometer bonds change material. Then spread the bonds change materialon the textile surface. Thus do not ceeate the oil bath influence on the textile and the bonds change material is stable and has relitave high change enthalpy and sutible temparature adjustment sector. Moreover, the preparation method's technological process is simple, the requests is low, and the reaction process is easy to control.
Description
Technical field
The present invention relates to a kind of intelligent textile and preparation method thereof, particularly relate to a kind of intelligent temperature-regulation fabric and preparation method thereof.
Background technology
Raising along with living standards of the people, people are progressively changed pursuit to its " functional ", " comfortableness " into from simple " warmth retention property " for the requirement of clothes, and are wherein wrinkle resistant, fire-retardant, refuse coming out one after another of functional textile such as oil, Waterproof Breathable and greatly promoted the development of after-finishing of textile products technology.Along with constantly widening and the continuous development of the process technology of weaving of research field, people have had new understanding and understanding to the most basic warming coldproof function of clothes.How fashion, aesthetic feeling and clothing heat insulation can organically be combined, use modern high-new weaving process technology, the machinery that only depends on of breaking continuity for many years increases, subtracts the traditional concept that dressing thickness is resisted the samsara of the Nature four seasons, change is static, passive resisting is dynamic, positive adjusting, give the breath of clothes, become people's hot issue with the New Times.
Intelligent temperature-regulation fabric environment temperature to external world has unique intelligent response, and when ambient temperature raise, it can absorb heat and be stored in textiles inside from environment; And when ambient temperature reduced, it can be emitted the heat that is stored in the textiles again, thereby formed a substantially invariable mesoclimate of temperature around it, reached thermoregulator purpose thus, and therefore this textiles is called the air-conditioning fabric again.Owing to this peculiar property of intelligent temperature-regulation fabric has great practical value it, therefore be subjected to consumers in general's welcome deeply, so market potential is huge.The home and abroad expert is consistent to be thought: function fabrics such as the Waterproof Breathable that continues appeared on the market after two more than ten years, and intelligent temperature-regulation fabric will be next most important, also were one of comfortable textile product of being worth of tool exploitation.
Phase-change material is a kind of chemical material that utilizes latent heat of phase change to come energy storage and exoergic.Phase-change material combined with textiles can develop intelligent textile with temperature adjusting performance, this textiles is a kind ofly to contain textile surface or fine phase-change material by dimension and meet hot and cold back and the solid-liquid reversible transition takes place absorb, emit energy, thereby has the novel high-tech textiles of temp regulating function.
The researcher has adopted kinds of processes that phase-change material is combined with textiles and has developed the intelligent textile with temperature adjusting performance at present, the most representative technology is as follows: (1) hollow fiber completion method, be about to phase-change material and be filled in the doughnut, thereby give fiber heat storing and heat preserving, temperature adjusting performance.This method is that the hydrated salts such as sodium sulphate, calcium chloride or strontium chloride that will have the crystallization water are enclosed in the doughnut, the salt that utilization contains the crystallization water fusion during variation of ambient temperature or process of setting around absorbs or emits heat, but because crystalline hydrate salt has phenomenon of phase separation, therefore, the practicality of this fiber is not strong.(2) microcapsule method, this method are that the phase-change material that will have specific range of temperatures coats with physics or chemical method with some macromolecular compound or inorganic compound, and make diameter stable solia particle under normality between 1 μ m～100 μ m.Though this method has technical maturity, raw material is easy to get and be easy to advantages such as large-scale industrial production, but the problem that exists is the solid-liquid phase as core becomes the phase transformation Volume Changes of material up to more than 15%, therefore require the macromolecule encapsulated layer that enough thickness and intensity must be arranged, so not only can increase the cost of microencapsulation, and pucker ﹠ bloat will influence service life repeatedly.In addition, the thermal conductivity factor of such material is very low, therefore needs to add thermal conducting agent under many occasions, will certainly reduce regenerative capacity and temperature adjusting ability like this.(3) composite spinning method, this method be with phase-change material with carry out spinning after spinning solution mixes.It is core composition or island component that Japanese ester company in 1993 has proposed with the aliphatic polyester, is skin composition or sea component with the general polymer, adopts the preparation of melt composite spinning method to have the patent application of heat absorption, heat release functional fibre.It is core composition or island component that Japanese Japan in 1994 spins that company proposed with the polytetramethylene glycol, is skin composition or sea component with the general polymer, adopts the preparation of melt composite spinning method to have the patent application of heat absorption, heat release functional fibre.In the end of the year 2000, Tianjin University of Technology has developed phase change material content more than 16%, and filament number is the heat-accumulation temperature-adjustment fiber of 5dtex, and this technical scheme has obtained national inventing patent.Tsing-Hua University opens third of the twelve Earthly Branches equality people and utilizes the temperature adjustment function of phase-change material to develop medical cooling clothes during SARS, but therefore this method is difficult to realize industrialization to the requirement height of equipment.(4) coating, this method be with phase-change material with directly be coated on after adhesive mixes on the textiles and make intelligent temperature-regulation fabric, has simple advantage, but, since most of phase-change materials when undergoing phase transition with the generation of liquid phase, therefore the negative effect that when the heat absorption melting takes place, can bring similar oil immersion shape to appearance of fabrics, thereby reduced the product wearability of utilizing this method to make, usually adopt the method that reduces phase-change material content on the fabric to solve this problem, but this can reduce the thermoregulation effect of fabric equally.
Sol-gel processing is that a kind of full dimension material wet-chemical that can prepare from the zero dimension to the three-dimensional material prepares reaction method.This method is that to utilize liquid chemical reagent (or be dissolved in solvent powdered reagent) or colloidal sol be raw material, evenly mix under liquid phase as reactant and react with this raw material, reaction product is the stable sols system, change gel into through placing certain hour, remove liquid medium by evaporation then and promptly may be molded to required goods.At present this method has been widely used in numerous areas such as electronics, composite, biology, pottery, optics, electromagnetism, calorifics, chemistry and environmental treatment, but gel and phase-change material are applied to textiles after compound and make intelligent temperature-regulation fabric and up to the present do not appear in the newspapers as yet.
Summary of the invention
