Description
Technical field
Drift technical field is boiled the invention belongs to weave, is related to a kind of biology enzyme for roving boiling and bleaching to boil drift agent and utilize and is somebody's turn to do
Biology enzyme boils drift agent, the roving boiling and bleaching method with supercritical carbon dioxide as medium.
Background technology
Flaxen fiber is the quality plant fiber that the mankind use earliest, accounts for the 1.5% of natural fiber total amount.Its chemical composition master
Will be including cellulose, hemicellulose, pectin, lignin, wax and nitrogen substance etc., wherein hemicellulose, lignin, pectin are difficult
To remove, and the crystallinity and the degree of orientation of flaxen fiber molecule are higher, it is easy to ductility, elasticity to fiber, convergence, flexibility
Influence is produced with crimpiness, inconvenience is brought to fibrilia spinning weaving process.Therefore, numb roving boiling and bleaching dye is always fiber crops
Spin the problem of industry concern.For many years, many research work are all based oneself upon and solve this problem, until later stage the 1950's,
People are just begun one's study roving boiling and bleaching dyeing technique, and wet spinning is carried out after roving boiling and bleaching is contaminated, and make accompaniment fully swelling, so as to remove
Partial impurities, increase fiber spinnability.The end of the fifties, China successfully have developed flax roving and boil bleaching and dyeing technique, and the end of the seventies is sub-
Numb roving boiling and bleaching dyeing equipment is substantially perfect.
It is main with water as medium in traditional fiber crops roving boiling and bleaching dye process, sequentially pass through soda boiling, chlorite bleaching, water
Wash, hydrogen peroxide bleaching, water Xian, sour Xian, water Xian's operation, hemicellulose, lignin and pectin in removal fiber, it is final meet spin
To the requirement of numb roving fibers intensity and whiteness in yarn operation.Numb rove eliminates part adhesive fiber after boiling and bleachinging and dyeing treatment
Between material, reduce the contact between fiber, improve the fiber thinness of flaxen fiber, increased the spinnability of flaxen fiber.So
And, traditional flax roving boils bleaching and dyeing process has the shortcomings that water consumption big energy-consuming, technological process be long, financial cost is high.Meanwhile, boil drift
After dye production, containing auxiliary agents such as substantial amounts of sodium chlorite, soda ash, hydrogen peroxide in the sewage of discharge, brought to environment serious
Pollution.
When material under normality temperature and pressure be higher than its critical-temperature and critical pressure when, the material be transform into it is super
Critical fluids.In the supercritical state, the minor alteration of pressure and temperature, can cause the significant difference of fluid density, and table
It is now the change of fluid solubility, so that supercritical fluid has application value.Is held from West Germany Essen in 1978
One " supercritical fluid extraction " international conference rises, and over more than 30 years, supercritical liquid extraction technique is widely used to medicine, changes
The fields such as work, food and environmental protection.Supercritical liquid extraction technique is under conditions of chemical composition is not changed, using shooting flow
The solvability of body and the relation of its density, supercritical fluid is contacted with separate substance, makes it selectively that polarity is big
The composition of small, boiling point height and molecular size range is extracted successively, and supercritical fluid is dissolved using temperature and pressure then
The influence of ability and realize extract and separate purpose.In conventional material, carbon dioxide is so that its is nontoxic, harmless, non-ignitable, with change
The quadrupole moment structure of inertia and uniqueness is learned, the features such as critical-temperature (31.1 DEG C) and relatively low critical pressure (7.37MPa), as answering
Use most commonly used supercritical fluid.
The high pollution of bleaching and dyeing process, high energy consumption problem are boiled in order to solve flax roving, a kind of overcritical titanium dioxide has been invented
Carbon biology enzyme boils drift agent and its application method, and cleaning to boil and bleachinging and dyeing life for rove is realized instead of aqueous medium using carbon dioxide
Produce, the technology shifts upgrading for bast industry is significant.
