Abstract
The present invention relates to a technique for producing new cotton by old cotton as main raw material, which belongs to the filed of chemical engineering. The present invention has the technical scheme that renewed cotton is white and has no bacterium or toxin, and the renewed cotton can be used for textiles, medical care and sanitation, civil cotton, quilt covers, etc. The present invention has the technical process that the old cotton is sorted and is soaked by hot water, and the old cotton is washed by sodium carbonate and is cleaned by washing powder; the cotton is bleached and is mercerized, and the cotton is neutralized by sulfuric acid and is delivered to an opening machine after being dried, and the new cotton is produced by a packing machine through packaging.
Description
The present invention relates to be technology with old cotton production new cotton technology.
The old and useless cotton of using in the past because therefore no reconditioning technology is not discarded, is exactly to be reclaimed by the salvage station.Refuse can not obtain utilizing like this, has polluted environment again.
The present invention seeks to alleviate the cotton short supply state, improve the value of old cotton, with the technology of old cotton production new cotton technology in order to enlarge the cotton source.
According to production practices, think that textile industry to some finishing technique of cotton, can be applicable in the renovation to old cotton, and made test of many times, found the technological process and the process conditions that are suitable for, finished the present invention.Facts have proved that its technology is reasonable, equipment is simple, small investment, and instant effect, raw material sources are abundant, and cost is low, and remarkable in economical benefits can turn waste into wealth.Adopt the cotton of the present invention's renovation, soft pure white, aseptic nontoxic.Can be used for weaving, health care, civilian cotton, quilt cover etc.
Process route of the present invention and process conditions are provided by following examples and accompanying drawing thereof.
Its production technology is: 1, hot water gives and soaks pot, and 2, the alkali cleaning pot, 3, cleaning pot, 4, digester, 5, Bellmer, 6, mercerising pot, 7, drier, 8, opener, 9, baling press, 10, bleaching liquor preparation vessel, 11, chlorine cylinder, 12, the bleaching liquor pump, 13, bleach liquor setting tank.
With old and useless cotton according to its pollution condition sorting, put it into behind the weighing hot water give soak the pot (1), about 60 ℃ of hot water temperatures, start agitator, soak after 3 hours, drag for after draining into alkali cleaning pot (2), alkali lye is 0.5% sodium carbonate liquor, and 55～65 ℃ of temperature constantly stir, cleaned 40 fens, with dragging for behind the flushing with clean water secondary into cleaning pot (3), cleaning fluid should be 0.5% detergent liquid, 40 ℃ of liquid temperature again, open mixer, cleaned 40 fens, and washed 2～3 times with clear water again, put into digester (4), it in the digester (4) 0.02% caustic lye of soda, open mixer, boiled 15～20 minutes, use the clear water rinsing again, drag for into Bellmer (5), be 0.5% bleaching liquid in the pond, about 37 ℃ of liquid temperature are opened mixer, bleached 1 hour, and used the clear water wash clean again.Dragging for into mercerising pot (6), is 0.5% caustic lye of soda in the pot, and about 15 ℃ of liquid temperature are opened mixer, and mercerising 1 minute is totally removed residual chlorine with 0.2% sodium hydrogensulfite with flushing with clean water again, cleans with clear water again, and the brightening agent with 0.1% brightens.Use the clear water wash clean, survey its basicity, neutralize about PH7, with twice of water purification flushing with sulfuric acid with the PH test paper.Send into drier (7) after draining, after the drying, pack by baling press (9) after delivering to opener (8) shredding.The new cotton of aseptic nontoxic pure white softness.
The preparation of bleaching liquid: in bleaching liquor preparation vessel (10), make (available chlorine content 2.2%) with liquid chlorine and milk of lime under certain reaction condition, send into bleach liquor setting tank (13) by bleaching liquor pump (12), use for bleaching process the clarification back.
A supplies water, and B is for steam, and C is for bleaching liquor, D condensed water, E liquid chlorine, F washing powder, G caustic soda.
Claims (2)
1, a kind of technology with old cotton regenerated new cotton is characterized in that, with old cotton according to its pollution condition sorting, put it into behind the weighing hot water give soak the pot (1), about 60 ℃ of hot water temperatures start agitator, soak after 3 hours, drag for after draining into alkali cleaning pot (2), alkali lye is 0.5% sodium carbonate liquor, 55～65 ℃ of temperature, constantly stir, cleaned 40 fens, with dragging for behind the flushing with clean water secondary into cleaning pot (3), cleaning fluid should be 0.5% detergent liquid again, 40 ℃ of liquid temperature, open mixer, cleaned 40 fens, wash 2-3 time with clear water again, put into digester (4), be 0.02% caustic lye of soda in the digester (4), open mixer, boiled 15～20 minutes, use the clear water rinsing again, dragging for into Bellmer (5), is 0.5% bleaching liquid in the pond, about 37 ℃ of liquid temperature, open mixer, bleached 1 hour, and used the clear water wash clean again, drag for into mercerising pot (6), be 0.5% caustic lye of soda in the pot, the liquid temperature is about 15 ℃, opens mixer, mercerising 1 minute, clean with flushing with clean water again, remove residual chlorine with 0.2% sodium hydrogensulfite, clean with clear water, the brightening agent with 0.1% brightens, use the clear water wash clean, survey its basicity with the PH test paper, neutralize about PH7, with twice of water purification flushing with sulfuric acid.Send into drier (7) after draining, after the drying, deliver to after opener (8) shredding by baling press (9) packing, the new cotton of aseptic nontoxic pure white softness.
2, technology according to claim 1, it is characterized in that, described bleaching liquid, its preparation process condition is in bleaching liquor preparation vessel (10), under certain reaction condition, make (available chlorine content 2.2%) with liquid chlorine and milk of lime, send into bleach liquor setting tank (13) by bleaching liquor pump (12), use for bleaching process the clarification back.
