Abstract
The invention discloses a viscose preparation technology for production of viscose fibers, which comprises the processes of: carrying out cooking, beating, bleaching, purifying, pulping and forming on natural fibers to prepare wet pulp which has the water content of 40% to 70%; putting the wet pulp into sodium hydroxide lye to be soaked for achieving technological requirements; and preparing spinning viscose by the procedures of compression, pulverization, aging, etiolation, maturation and the like. Compared with a traditional production technology for preparing the viscose by using pulp with about 10% of water content, in the viscose preparation technology, 0.2 ton of standard coals for steam consumption of each ton of viscose fibers are saved, control points of relevant technologies are reduced, and the technological accident rate is reduced. The viscose preparation technology is beneficial to enhancing the product quality.
Description
Technical field
The present invention relates to the viscose preparation technology in a kind of viscose preparation technology, particularly production process of viscose fiber, belong to the textile product technical field.
Background technology
The traditional processing technology of viscose fiber manufacturing be with natural fibers such as cotton, fiber crops, timber by boiling, making beating, bleaching, removal of impurities, copy operations such as slurry moulding, oven dry, make moisture about 10%, fixed weigh 700 ± 100 grams/square metre pulp, again with pulp by mix batch, operations such as alkalization, squeezing, pulverizing, experienced, yellow, maturation make the spinning viscose glue, the spinning viscose glue is spun into fiber through spinning-drawing machine, make qualified product through operations such as concise, oven dry, packings again, be used for selling.Moisture about 10% pulp can be cut into the pulpboard of certain size, after packing, can store, transport, and is used for viscose glue production or sale.There is part enterprise only to produce pulp now, is sold to viscose fiber manufacturing enterprise as raw material.Pulp alkalization operation is exactly pulp to be joined in the alkali lye that contains sodium hydroxide 230～260 grams per liters flood, and is lower than 6% slurry congee so that the pulp swelling forms content of cellulose, and slurry congee process again squeezes, pulverizes and produce soda cellulose.Pulp can not dried under proper condition, as long as promptly make content of cellulose and sodium hydrate content in the slurry congee that pulp forms after the swelling in alkali lye reach processing requirement, can finish the alkalization of pulp.Viscose fiber manufacturing enterprise is as being equipped with the pulp production line of oneself, and to prepare vehicle headway nearer with viscose glue, if adopt again the moisture content in the pulp is reduced to about 10%, and then put into the prepared viscose glue that floods in the alkali lye, not only can cause the waste of the energy, also artificial increase the reference mark in the production process, make the quality control of fiber production and cost control all increase difficulty.
Summary of the invention
The object of the present invention is to provide a kind of less energy-consumption, technology advanced person's the viscose preparation technology that viscose fiber is produced that is used for.
The objective of the invention is to realize by following technological process:
With natural fiber by boiling, making beating, bleaching, removal of impurities, copy slurry and make the wet pulp dregs of rice after the moulding, the water ratio of the wet pulp dregs of rice is 40%～70%, the wet pulp dregs of rice are put in the sodium hydroxide lye dipping and are reached processing requirement, make the spinning viscose glue by operations such as squeezing, pulverizing, experienced, yellow, maturations again.
Above-mentioned natural fiber comprises natural fibers such as cotton, fiber crops, timber.
Be ground into the particle that size is not more than 20 millimeters with pulverizer before the above-mentioned wet pulp dregs of rice flood in putting into sodium hydroxide lye, the particle optimum size is 4～5 millimeters.
The above-mentioned concentration that is used to flood the sodium hydroxide lye of the wet pulp dregs of rice is 230～260 grams per liters.
Above-mentioned natural fiber by boiling, making beating, bleaching, removal of impurities, copy the wet pulp dregs of rice that slurry is made after the moulding, its optimum moisture content is between 43%～55%.
In order to guarantee the viscose fiber quality product, other quality index of the above-mentioned wet pulp dregs of rice is carried out according to the concerned countries standard that contains pulp.
Viscose preparation technology of the present invention, owing to removed the baking operation of pulp, saved the steam that is used to dry pulp, the production technique for preparing viscose glue than moisture about 10% the pulp of traditional employing, the steam consumption of viscose fiber per ton can be saved 0.2 ton of standard coal, because the wet pulp dregs of rice are directly delivered to viscose glue and are prepared the workshop, removed the packing of pulp from, storage, links such as transportation, not only save production cost, also reduced the probability of the secondary pollution of pulp, improved the quality of product, simultaneously owing to deducted operation such as pulp oven dry, reduced the related process reference mark, reduced technology accident, favourable improving the quality of products.
Embodiment
Below in conjunction with specific embodiment process program of the present invention is described further:
Embodiment
With 2 kilograms of cotton fibre by boiling, making beating, bleaching, removal of impurities, copy slurry and make moisture 55% the wet pulp dregs of rice after the moulding, then the wet pulp dregs of rice are ground into pulverizer and are of a size of 4 millimeters particle, wet pulp dregs of rice particle is put in the sodium hydroxide lye that concentration is 240 grams per liters again and is flooded, and the slurry congee of dipping after finishing is made the spinning viscose glue by operations such as squeezing, pulverizing, experienced, yellow, maturations again.
Claims (4)
1. one kind is used for the viscose preparation technology that viscose fiber is produced, it is characterized in that: with natural fiber by boiling, making beating, bleaching, removal of impurities, copy slurry and make the wet pulp dregs of rice after the moulding, the wet pulp dregs of rice are put into to flood in the sodium hydroxide lye and are reached processing requirement, make the spinning viscose glue by operations such as squeezing, pulverizing, experienced, yellow, maturations again, the water ratio of the above-mentioned wet pulp dregs of rice is 40%～70%.
2. a kind of viscose preparation technology that viscose fiber is produced that is used for according to claim 1, it is characterized in that: be ground into the particle that size is not more than 20 millimeters with pulverizer before the above-mentioned wet pulp dregs of rice flood in putting into sodium hydroxide lye, the particle optimum size is 4～5 millimeters.
3. a kind of viscose preparation technology that viscose fiber is produced that is used for according to claim 1 and 2, it is characterized in that: the concentration of above-mentioned sodium hydroxide lye is 230～260 grams per liters.
4. a kind of viscose preparation technology that viscose fiber is produced that is used for according to claim 1 and 2, it is characterized in that: the optimum moisture content of the above-mentioned wet pulp dregs of rice is between 43%～55%.
