Abstract
The invention discloses a method for cleaning and degumming cotton stalk bark fiber, combining flash explosion, high pressure and high pressure. The inventive method comprises that: washing cotton stalk bark in water, drying, flash explosion, washing in hot water, washing in water, degumming chemically, washing in water, bleaching, washing in water, dewatering, feeding oil to soften, removing oil, drying, and ultra drying cotton stalk bark fiber. The invention first utilizes flash explosion technique to degrade part of semi-cellulose and lignin, utilizes chemical technique to treat cotton stalk bark in order to remove the lignin deeply and bleaches via hydroperoxide to obtain white soft cotton stalk bark fiber. The lignin content of inventive cotton stalk bark fiber is lower than 0.5% while the content of semi-cellulose is lower than 10%, compared with disclosed technique, the inventive method can shorten treatment time effectively.
Description
Technical field
The present invention relates to Degumming method, particularly relate to a kind of quick deguming method for cotton stalk peel fiber.
Background technology
Cotton stalk bark is a kind of good bast fiber, is the main byproduct fiber that plant cotton brings, and accounts for about 30%～35% of cotton bar, and its content of cellulose is about 62.8%.China second produces cotton big country in the world, and cotton stalk 225～250kg is produced in one mu of cotton field, and skin zone accounts for 26%, and the existing cotton stalk annual production of China reaches 1,530 ten thousand tons, and 4,000,000 tons/year of cotton stalk barks are arranged, and the cotton stalk bark resource is extremely abundant.Therefore having made full use of the cotton stalk bark resource is significant to alleviating Cotton in China fiber wretched insufficiency.But the past people usually with cotton stalk bark fibre as papermaking material, also applied for simultaneously much patents, as CN1068866, CN1052484 about cotton stalk bark pulping and paper-making aspect.
Along with the mankind day by day uphold nature, pursue the trend recover one's original simplicity, and human concern to environmental problem and life and health, natural fabric causes people's attention day by day with its special performance and environmental protection function.But China faces a large amount of textile garments breach with natural fabrics every year, therefore how to develop a large amount of cotton stalk bark fibres and is subjected to increasing people and notes.For example disclose the method that a kind of cotton stalk bark extracts textile fabric in Chinese patent ZL94113220.X, this patent is soaked back with technologies such as 8～15g/L caustic soda boil by the sulfuric acid with 0.5～2g/L.Chinese patent 200510034201.4 and 200610036594.7 discloses cotton stalk bark fibre and processing method and a kind of cotton stalk crude fiber and processing method thereof respectively, and is similar among the extraction process of its fiber and the ZL94113220.X.Though they are utilizing cotton stalk bark to make a positive step aspect textile material, but the method that they adopt exists long shortcoming of time spent, having altogether as the processing time among the patent ZL94113220.X need be about a week, and in patent 200510034201.4 and 200610036594.7 processing time also need about 3～4 days, in weaving, use for like this cotton stalk bark fibre and bring a lot of unfavorable factors.
Summary of the invention
It is short to the purpose of this invention is to provide the process time, and uniform a kind of quick deguming method for cotton stalk peel fiber comes unstuck.
Technological process of the present invention is: the cotton stalk bark washing, and------------washing--is bleached--washing--dehydration--oil supply soft treatment----de-oiling--oven dry---refined waste silk fiber to chemical Degumming to hot water wash in washing to dodge quick-fried processing in oven dry; Promptly adopt one quick-fried one to boil one and float a soft technology.
Below technology of the present invention is described in further detail:
(1) with cotton stalk bark fibre decontamination washing back oven dry;
(2) 1m that packs into of the cotton stalk bark fibre after will drying
3Dodge quick-fried jar in, feed saturated vapor, make pressure arrive 1～2Mpa, kept pressure 5～10 minutes, the moment release is 3～5% 50 ℃～70 ℃ hot water cleaning then with alkalinity, washes at last, obtains dodging quick-fried cotton stalk bark fibre;
(3) the quick-fried cotton stalk bark fibre of sudden strain of a muscle after will cleaning carries out chemical Degumming, and the prescription quality percentage of chemical Degumming is: NaOH is 5～10%, sodium metasilicate 2～4%, sodium phosphate trimer 1～2%; Bath raio is 1: 10～15, is heated to 90～100 ℃, boils 1～2 hour, takes out then to wash;
(4) cotton stalk bark fibre of handling well is bleached, is washed, dehydration, oil supply soft treatment, de-oiling, oven dry, shredding, obtains cotton stalk bark fibre at last, and this processing method is conventional processing method.
In the hydrogen peroxide bleaching operation, the concentration of hydrogen peroxide is 7～10g/L, and bath raio is 1: 10～15, and pH is 10～11, and temperature is to bleach 30～45 minutes under 70～85 ℃ the condition;
In the oil supply softening process, the concentration of softening agent is 2.5～3.5%, and the softening processing time is 1.5～2 hours, and temperature is 75～85 ℃.
In above each operation:
1, washing is in order to remove impurity such as earth etc., and part removes the hydrotrope in some cotton stalk barks, to reduce the burden that the back operation is come unstuck, improves the quality of cotton stalk bark fibre.
2, dodging quick-fried is in order to deviate from the hemicellulose and the lignin of pectin in the cotton stalk bark fibre, the hydrotrope, adipocere matter, part.
3, the effect of hot water wash mainly is that the hemicellulose and the lignin that prevent to have deviate from are agglomerated together again once more, is difficult on the cotton stalk bark fibre wash off thereby be attached on.
5, in the chemical Degumming operation, chemical Degumming is to deviate from difficult hemicellulose and the lignin that removes in the cotton stalk bark for the further degree of depth, NaOH plays swelling action to cellulose, hemicellulose and lignin, and particularly hemicellulose and lignin make it cracking and become soluble substance.Used sodium metasilicate and sodium phosphate trimer play osmosis and alkali are played cushioning effect.
6, adding softener is in order to prevent that cotton stalk bark fibre from sticking together again when drying.
The beneficial effect that the present invention has is:
Cotton stalk bark fibre of the present invention pure white soft, quality good, dodges quick-fried processing and at first remove part lignin and hemicellulose and other materials in the cotton stalk bark, lay the foundation for chemical Degumming like this.Content of lignin in the cotton stalk bark fibre after this PROCESS FOR TREATMENT is lower than 0.5%, and hemicellulose level is compared with the disclosed cotton stalk bark fibre patent treatment process time less than 10% simultaneously, and this process treatment time will shorten greatly.
