Description
Technical field
The invention belongs to the preparation field of weaving twice-laid stuff, particularly a kind of method of green reclaim discarded clothes transformation tissue culture thing.
Background technology
Follow growth in the living standard, the duds thing of eliminating has in a large number been piled up by numerous families, becomes " indoor pollutant ", and how huge duds thing is treated as puzzlement resident's a difficult problem, also to environment, brings certain pressure to a certain extent.Past buries exactly to the simplest directly treatment process of these wastes, but the method for burying takies a large amount of soils, and in today of land resources growing tension, the method for burying has been suffered the day by day fierce opposition of people.Burning can be described as a kind of reasonable method; but it is to be noted; if incomplete combustion in burning process; will produce toxic gas; atmosphere is polluted, so so people are constantly surging to the opposition cry of burning method, so carry out the recycling of waste and old clothing; both save resource, protected again environment.
In discarded synthetic textile, the high polymers processing and utilization has two approach, and the one, these fibers are all a kind of macromolecular materials, mostly have solvable (melting) OK, can adopt the method for melting or dissolving to reclaim these macromolecular materials, directly make other purposes.The 2nd, the macromolecular material reclaimed further is cracked into to high polymer monomer, the fiber product processed of respinning regroups.It is generally by vegetable fibre (cotton, numb etc.) and animal fibre (wool fiber) that natural fiber is recycled, yarn or fabric (duds thing) are resolved into fibrous with machinery, then carries out pure time and spins or blending, woven into fabric.Vegetable fibre also can do the non-woven raw material or treated (being mainly decolouring, de-oiling fat) makes viscose fiber, Lyocell fiber and paper making raw material.
Ionic liquid dissolves natural fiber and synthon as a kind of green organic solvent, its dissolution route is exactly first to take the swelling of non-crystalline region and crystallizing field as main, and then break macromolecular ordered arrangement and intermolecular crosslinked, under the effect of temperature, increase the velocity of diffusion of ionic liquid, ionic liquid and macromolecular size differ greatly, and both molecular motion speed also difference is very large, and when temperature is high, ionic liquid could penetrate into fibrous inside faster; The motion of ionic liquid has been accelerated in the rising of temperature, given ionic liquid enough energy, make ionic liquid can overcome solid barrier and the macromolecular repulsive force of crystallizing field, increased the chance that ionic liquid contacts with the fibrous inside lateral ties, thereby make that the fiber macromolecular chain is loosening, slippage, separation, finally form the spinning solution mixed.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method of green reclaim discarded clothes transformation tissue culture thing, and this invented technology is simple, easy to operate, and green non-pollution, to staff and environmental friendliness.
The method of a kind of green reclaim discarded clothes transformation tissue culture thing of the present invention comprises:
(1) by the discarded clothes classification, use water rinse, Organic Alcohol cleans, and bakes and is dried to constant weight;
(2) discarded clothes is shredded, then mix with ionic liquid, solvent temperature is under 25-130 ℃ of condition, stirring and dissolving 1-15h, and obtaining solute is the solution that cellulosic mass percentage concentration is 7-20%, deaeration, solidifies, washes, dries, and obtains regrowth.
In described step (1), discarded clothes is categorized as synthon clothing and natural fiber clothing by composition.
Described synthon clothing is a kind of in terylene, polyamide fibre, acrylic fibers.
Described natural fiber clothing is a kind of in cotton, fiber crops, hair, silk, regenerated cellulose.
Organic Alcohol is a kind of in methyl alcohol, ethanol in described step (1).
Described step (2) intermediate ion liquid is a kind of in imidazoles, pyridines, benzimidazoles ionic liquid.
Described ionic liquid is 1-butyl-3-Methylimidazole bromine salt ion liquid.
Deaeration condition in described step (2): temperature is 80 ℃, and pressure is 0.01MPa-0.1MPa.
In described step (2), solution solidification value in precipitation bath is 25-90 ℃.
Described precipitation bath is one or more in deionized water, tap water, alcohol, and the percentage composition of alcohol is 0-100%.
The method of a kind of green reclaim discarded clothes transformation tissue culture thing of the present invention.Utilizing the present invention, while reclaiming discarded duds thing, without auxiliary agents such as other modifying agents, tensio-active agents, prepare the regrowth solvent composition very simple, is ionic liquid in principle.Fragment and the ionic liquid of discarded natural fiber or synthon duds thing are mixed, form mixed solution under temperature action, mixed solution is poured on film-forming plates, and then after vacuum defoamation film forming, made mixing solutions is placed in suitable container, put into suitable precipitation bath film-forming, curing rear taking-up washing is dried can biology again.So the simple process waste, do not produce auxiliary agent and pollute, and solves the pollution problem of waste water.
Specifically, the present invention's design provides a kind of method and technology of green reclaim discarded clothes transformation tissue culture thing.Applying above-mentioned ionic liquid is that solvent is dissolved synthon, natural fiber etc., and the mixing solutions that dissolves rear formation is regenerated.
When reclaiming discarded duds thing, only contain required synthon, natural fiber and ionic liquid in mixing solutions.
beneficial effect
(1) the present invention improves the use value of discarded duds thing, again the consciousness that reclaims and utilize by promoting the duds thing, reduce the discharge of waste, the reclaiming waste is to realize that the low-carbon (LC) life lays equal stress on recycling economy, realizes fashion and low-carbon (LC) one of the important means of Development patterns of going together;
(2) the inventive method technique is simple, easy to operate, and green non-pollution, to staff and environmental friendliness.
