Description
Belong to light industry, chemical field.
Cigarette-used plastic cotton is second cellulose acetate (or claiming secondary cellulose acetate) tow of 39000TD specification.Cellulosic solvent and problems of dissolution no matter on the cellulose industry or in the theoretical research, all are important problem.Because cellulose is insoluble to usual vehicle, therefore,, all it is transformed into derivative and utilizes on the cellulose industry or in the theoretical research.Study cellulosic solvent, particularly new solvent is that people inquire into always.If can with cellulose directly dissolving become solution, industrially can shape again, that will bring very big change to cellulose industry.Therefore, study cellulosic solvent and seek novel solvent, have important and practical meanings.
According to the high weaving school teaching material of publishing textile industry publishing house in May, 1985, " cellulose and the viscose " that the gift of poplar, Wang Qingrui, Jiang Tingpei, Wu Guoming compile, " cellulose chemistry " two book introductions that the gift of the poplar that light industry publishing house published in 1961 is compiled and " Ci hai " record, again through repeatedly experiment, second cellulose acetate can be dissolved in acetone well, become solution, carry out spinning.Acetone: chemical formula CH
3COCH
3, the simplest a kind of ketone, available starches fermentation method or by acetic acid, calcium acetate (this material destructive distillation byproduct), propylene and acetylene or isopropylbenzene set out and make.Colourless liquid, 56.5 ℃ of boiling points, lighter than water, little perfume (or spice) is arranged, easily catch fire.Energy and water, ether, ethanol mixes mutually.Chemical property is active.Cellulose diacetate is dissolved in acetone, becomes solution, after being shaped with spinning machine spray silk,, just can at an easy rate acetone be removed setting with method of evaporating because of the boiling point of acetone only is 56.5 ℃.Because the Triafol T and first cellulose acetate are not dissolved in acetone, and cellulose diacetate can be dissolved in acetone well, so purification rate is very high, can ensure the quality of products.
The cigarette-used plastic cotton tow that cigarette-used plastic cotton waste product regeneration is new.
Cigarette-used plastic cotton mainly relies on import, the source of goods is very in short supply, with moulding the cotton cigarette filter rod of making, raw material can not utilize fully, and the national regulation percent defective is 10%, estimates that the annual rejection number in the whole nation reaches two kilotons, these mould cotton except that costing an arm and a leg, because of being the cigarette filter rod dedicated fiber, powerful very poor, can not weave.There is not the suitable approach that utilizes.The utility model utilizes solvent exactly, and these waste products directly are dissolved into solution, after shaping solvent is removed the raw material that regeneration is new.
Its production procedure:
Useless mould cotton-dedusting-dissolving-filtration-deaeration-spinning-reeling-roll up excellent moulding (filter rod finished product)
Owing to usedly useless mould that cotton just moulding is defective, through using.Dropped into some dusts when depositing, through dedusting, dust can all be removed before the dissolving.Solvent can only dissolve this a kind of cotton, reliable product quality of moulding.Remove the setting of desolvating with method of evaporating.Solvent is recyclable after the setting recycles.Changed traditional solidifying the cementing structure and cellulose is transformed into the traditional handicraft that derivative utilizes.Cigarette-used plastic cotton only needs 39000TD specification, and the allowable error scope is between 37000TD-41000TD, and in the flourishing China of textile industry, the tow of producing this specification with textile technology can be described as easy.Just, need reform the hole shape of spinning machine, spinneret orifice for guaranteeing the cigarette filter rod filter effect.It is several that the hole shape of present domestic spray silk machine spinneret orifice is generally circle, prismatic, triangle and hexagon, the tow that these several hole shapes are produced, as be used for weaving and can gain in strength, but be used to roll cigarette filter rod, and once extruding, the easy asphyxia by external pressure on the chest and abdomen of hole all around.Need hole shape is changed into star (as accompanying drawing), after rolling extruding, formed honeycomb like this, hole is crowded not dead around making, and has guaranteed filter effect.After spinning out tow, filter-stick forming device processing be can directly go up, post processing and packing do not needed to carry out.
To mould the cotton wastes product and directly be dissolved into solution with solvent, after shaping, evaporation is desolvated, the raw material that regeneration is new.Use common home equipment, reform that the spray orifice hole shape can use, common textile technology operation.
Can the expensive acceptable material of the reluctant waste product regeneration of each factory be turned waste into wealth.Because of cigarette-used plastic cotton mainly relies on import, the utility model both can be country and had saved a large amount of foreign exchanges, can be country again and increased the state tax revenue.Can effectively delay and close domestic very outstanding cigarette-used plastic cotton imbalance between supply and demand.
The drawing explanation: spinning head spray orifice figure, spray orifice hole shape figure, nozzle hole number and aperture are the requirement of 39000TD specification tow.All the other specifications are constant.
The utility model has mainly carried out 3 reforms:
1. changed that traditional cellulose is transformed into derivative and the method utilized.Make solvent with acetone and directly be dissolved into solution moulding the cotton wastes product.Shape the raw material that regeneration is new.
2. utilize method of evaporating that acetone is removed setting, recycled after reclaiming, changed traditional cementing structure that solidifies.
3. changed the hole shape of domestic spray silk machine spinneret orifice.By general circle, prismatic, triangle, hexagon reform star (as accompanying drawing) into.The tow of producing after rolling extruding, forms honeycomb shape, and hole is crowded not dead around guaranteeing, good filter effect is arranged.
Through after these 3 reforms, utilize the ordinary chemical fiber spinning equipment, use general chemical fibre textile operating technology, can be cigarette-used plastic cotton waste product regeneration country cigarette-used plastic cotton tow very in short supply.
Claims (2)
1, the present invention is a kind of materials recycling method of cigarette-used plastic cotton (diacetate fiber tow), it is characterized in that: with acetone (chemical formula CH
3COCH
3) as solvent, the cigarette-used plastic cotton waste material directly is dissolved as solution, after shaping with spinning machine, acetone (56 ℃ of boiling points) is removed setting, the cigarette-used plastic cotton that regeneration is new with method of evaporating.The acetone recycling use that evaporates.
2, renovation process as claimed in claim 1 is characterized in that: the hole shape that will spray silk machine spray orifice reforms Y shape into, makes the tow that bears again, after rolling extruding, forms peak nest structure, and hole is crowded not dead around guaranteeing, good filter effect is arranged.
