Description
Technical field:
The invention belongs to the textile industry field.Be characterized in a kind of and utilize lignin in the microbial degradation sodolin (fiber), and then finish the Totally-chlorine-free bleaching technology of bleaching with hydrogen peroxide.
Background technology:
Flax is the good natural fabric of a kind of kind, has the characteristics of comfortable and easy to wear, nice and cool pleasant, good permeability, thereby at home and abroad always as the raw material of high-grade clothing and ornament and popular to people deeply.
Bleaching is the significant process during sodolin is produced, and the outward appearance and the processability of sodolin played an important role.The linum bast fiber, content of cellulose has only 70-80% in the raw ramie, contains about 25% lignin.Linen fibre after retted fibre is handled also contains the lignin of 2-5%, is higher than cotton fiber far away.Because lignin molecule is made up of dysoxidizable aromatic ring and alkyl side chain, the bleaching difficulty that makes linen fibre is much larger than cotton fiber.At present, the bleaching medicament that uses in sodolin production mainly contains two big class, chlorine bleaches and oxygen-bearing bleaching agents.Chlorine bleaches principal item has chlorine, hypochlorite, chlorite, chlorine dioxide etc.Because chlorine and hypochlorite can produce chlorine when bleaching, thereby they are called contain the elemental chlorine bleaching agent.It is fine to contain elemental chlorine bleaching agent low price, easy to use, bleaching and delignification's ability, less to the cellulose degradation ability, be class selectivity bleaching agent preferably, its application technology is also very ripe, is the main bleaching agent that uses during linen industry is produced in a very long time.
1985, the scholar of European Section detected the extremely toxic substance dioxin first from the sodium hypochlorite bleaching waste liquid, had caused people to containing the attention to the organic matter chlorination in bleaching process of elemental chlorine bleaching agent.So far the dioxin-like chemical that detected from the bleaching waste liquor of flax of scientist reaches kind more than 200, also has strong carcinogens such as chloroform, alpha-halogen aldehydes in addition.Quite a few has carcinogenic, teratogenesis sex change, causes sudden and multiple cranial nerve pathology etc. in these organohalogen compounds, and has accumulation toxicity.They or be dissolved in the bleaching waste liquor or be deposited in the fabric fibre surface, bring serious pollution to environment.Foreign technology developed country, particularly western countries are after having experienced the pollution disturbance of dioxin to food, formulated strict environmental legislation one after another, the restriction chlorine bleaches use, and the AOX in the bleaching waste liquor (Absorbable Organic Halogens) content as an important control criterion.From then on, replace chlorine bleaches with chlorine-free bleaching process gradually abroad, to reduce the AOX in the bleaching waste liquor.Now, developed countries such as Europe, the U.S., Japan have stopped containing the application of elemental chlorine bleaching agent in weaving substantially.
Oxygen-bearing bleaching agent generally is far smaller than chlorine bleaches to the effect of lignin, so, realize chlorine-free bleaching, must develop the method for lignin in the new free of contamination removal fabric fibre.Particularly contain the more fiber of lignin like this for linen fibre, can remove delignification be the key that effectively bleach.
The bio-bleaching technology is the nearly 30 years a kind of new technologies that grow up in paper industry, owing to equally also contain a large amount of lignin in the lumber fibre, the removal lignin is the key technology in the lumber fibre bleaching process too.The reported first such as Viikari of Finland in 1986 handle with the zytase of whiterot fungi (Phanerochaete chrysosporium) secretion and do not float paper pulp and can strengthen its bleachability, this is that related microorganism participates in the report of bleaching for the first time.Because potential application prospect, this report has excited the research extensive interest of people to this respect.Finland in 1989 have taken the lead in carrying out the industrial test of zytase bleached pulp, and some pulp mills of Northern Europe and north America region begin to adopt this technology subsequently.Further research work shows, a lot of subspecies of whiterot fungi all have the effect of decomposing lignin, for example Phanerochaete chrysosporium (Phanerochaete Chrysosporium) conchoidal grass ear bacterium (Panusconchatus), variegated manyzoned polypore bacteria (Coriolus versicolor), oyster cap fungus bacterium (Pleurotusostreatus) etc.In addition, discover that some black rot genus, bacterium, actinomyces also have secretion such as zytase, hemicellulase ability, these enzymes also have good booster action to the bleaching of paper pulp.
The mechanism of action of bio-bleaching mainly is that used Pseudomonas can produce fiber bleached useful enzyme system, mainly by zytase, hemicellulase, lignin-degrading enzymes (comprising manganese catalase, lignin peroxidase, laccase etc.).Zytase and hemicellulase change the string structure, from the effect that cellulose is peeled off lignin, and the then direct lignin degrading of lignin-degrading enzymes.Lignin in string is removed, and uses the bleaching of oxygen water again and just can obtain satisfied result.
The bio-bleaching of developed countries paper pulp has entered industrialized level, and China then still is in conceptual phase.The bio-bleaching technology of paper pulp has direct use microbial fermentation solution pulp treatment, also has various enzymes are separated to re-use, and obviously latter's use cost is greatly improved.
A significant deficiency of bio-bleaching is that microorganism is gone back the plain digestive enzyme of eccrine fiber in the required enzyme of secretion bleaching, so bio-bleaching process makes cellulosic molecular weight that bigger reduction be arranged.This shortcoming can also accepted the less relatively field of papermaking of cellulose requirement of strength, but just unacceptable concerning the textiles of cellulose requirement of strength strictness.So, up to the present, also do not have the bio-bleaching technology in the bleaching of linen fibre, to be applied.
