Abstract
The invention relates to a stabilizer for hydrogen peroxide bleaching of linen rove and the textile and the new technology of degumming and bleaching for green environment protection. The stabilizer comprises 5-15% of diethylene triamine pentaacetate methylene phosphonic acids, 2-8% of sepiolite, 2-10% of montmorillonite, 1-6% of iron oxide, 1-5% of magnesium oxide, 1-8% of alumina oxide, 2-12% of gluconate, 6-20% of boric acid, 1-6% of sodium silicate, 1-8% of non-ionic surface active agent and distilled water. The stabilizer in the invention possesses merits of absorbed and chelated types and does not have their shortcomings so as to achieve the requirement with high temperature resistance, alkali-resistant and high whiteness. During the using process, after absorbed and chelated stabilizers are mixed, they are assisted by certain non-ionic surface active agent, polysaccharide cellulose protective agent and little water glass; the component of mixed stabilizers and the consumption of hydrogen peroxide are adjusted so as to achieve the required whiteness for the flax with different quality in single oxygen bleaching.
Description
Technical field
The present invention relates to be used for the stabilizing agent of hydrogen peroxide bleaching of flax roving and fabric thereof and the degumming and bleaching new technology of environmental protection.
Technical background
Linen fibre and cotton fiber all belong to cellulose fibre, and it has nice and cool feel, good moisture absorption and wet putting the structures shape of flax.The trend of advanced, differential and natural fabricization that sodolin caters to, these advantages make sodolin enjoy the consumer to like.But flax roving and fabric degumming and bleaching thereof are paced up and down in the vicious circle that inferior oxygen floats all the time, both have been unfavorable for environmental protection, and be uneconomical again.
The flow process that traditional inferior oxygen bleaching process is general is pickling → chlorite bleaching → washing → hydrogen peroxide bleaching → washing.Wherein, the flow process of pickling is: roll acid (sulfuric acid 5～15g/L, room temperature) → bank up (room temperature, 15～30 minutes) → washing; The technology of chlorite bleaching: sodium chlorite consumption 10～30g/L, PH=4.0～4.5, activator acetic acid 5～10g/L, 80～102 ℃ of temperature, steaming time 0.5～1 hour.The technology of hydrogen peroxide bleaching is: hydrogen peroxide 1～10g/L, sodium metasilicate 5～10g/L, pH=9.0～11.5,98～102 ℃ of temperature, steaming time 0.5～1 hour.This technology by regulating the concentration of soda acid, sodium chlorite and hydrogen peroxide, can obtain good whiteness for flax of different qualities under the situation of very violent damage fiber not, can satisfy requirement of client fully.But there is very big shortcoming in this technology: after 1. floated the Asia, a large amount of residual liquid discharges polluted environment; 2. sodium chlorite costs an arm and a leg, the waste substantial contribution; 3. the inferior chlorine dioxide that floats generation damages operating personnel are healthy for severe toxicity; 4. etching apparatus.
In view of above reason, each producer is all in the direction effort to the single hydrogen peroxide hydrogen peroxide of use both at home and abroad.Hydrogen peroxide is a kind of good bleaching agent, and it has, and the bleach product whiteness is pure, retention of whiteness good and do not have advantages such as pollution and etching apparatus.Hydrogen peroxide mainly plays two kinds of effects in traditional inferior oxygen bleaching process: the one, and dechlorination; The 2nd, auxiliary chlorite bleaching.These two kinds act in the inferior oxygen bleaching process advantage that basic embodiment does not go out hydrogen peroxide bleaching.
Single use hydrogen peroxide bleaching generally has two kinds of process routes at present: the one, and dioxygen floats; The 2nd, single oxygen floats.
Dioxygen floats promptly by twice hydrogen peroxide bleaching, mainly is the whiteness requirement that the dense and hydrogen peroxide concentration of alkali reaches semi-finished product rove or fabric in floating by twice oxygen before and after regulating.This technology can embody the advantage of hydrogen peroxide bleaching fully, but that major defect is technological process is longer.And single oxygen floats and can make finished product meet the requirements of whiteness, shortened process, but requires the stabilizer of hydrogen peroxide performance very good.
The stabilizing agent that uses during single oxygen floats requires to make hydrogen peroxide all even decomposition effectively in bleaching process, avoids linen fibre to suffer violent damage, and alkaline resistance properties is good.Hydrogen peroxide bleaching stabilizer can be divided into absorbent-type and chelating type two classes by its stable mechanism.
The absorbent-type stabilizing agent mostly is inorganic matter and organic matter macromolecular compound greatly, and using the widest is waterglass (sodium metasilicate).Waterglass is except producing the silicon dirt, and alkali resistance is also very poor, forms colloid above being unfavorable for being dissociated into silicic acid behind the 3g/L.Organic high molecular compound such as fatty acid magnesium salt are not alkaline-resisting yet, and whiteness is also relatively poor.
The chelating type stabilizing agent mostly is organic sequestering agent greatly, can chela and effect take place with metal ion and forms stable water soluble chelate compound, makes metal that catalytic action not take place.Metal carboxylate such as EDTA, HEDTA (hydroxyethylethylene diamine tri-acetic acid), DTPA (diethylene triamine pentacetic acid (DTPA)) effect are relatively poor, cost an arm and a leg, and carboxylic hydroxy kind such as GAS (gluconate) complexing power is stronger.But the shortcoming of chelating type maximum is metal ion can be concentrated as absorbent-type, the impurity of the catalytic decomposition hydrogen peroxide beyond can not chelated mineral.
Therefore, the stabilizing agent during single oxygen floats uses single function not reach requirement, must use absorption and chelating mixed type stabilizing agent.
Summary of the invention
A purpose of the present invention is to overcome the deficiency that existing inferior oxygen floats technology, and a kind of stabilizing agent that is used for hydrogen peroxide degumming and bleaching of flax is provided.
Another object of the present invention provides the preparation method of the stabilizing agent that is used for hydrogen peroxide degumming and bleaching of flax.
A further object of the present invention provides the purposes of the stabilizing agent that is used for hydrogen peroxide degumming and bleaching of flax.
An also purpose of the present invention provides that a kind of technology is simple, non-pollutant discharge, the flax roving of environmental protection and the new technology of fabric hydrogen peroxide degumming and bleaching thereof.
Stabilizing agent of the present invention is a kind of absorption and chelating mixed type stabilizing agent, in the process of flax degumming bleaching, add this stabilizing agent, can make hydrogen peroxide all even decomposition effectively in bleaching process, avoid linen fibre to suffer violent damage, reach the purpose of flax degumming bleaching, the discharging of contamination-free.
The stabilizing agent that is used for hydrogen peroxide degumming and bleaching of flax of the present invention, by percentage to the quality, by diethylentriamine five methylenephosphonic acids (DTPMP) 5～15%, sepiolite 2～8%, montmorillonite 2～10%, di-iron trioxide 1～6%, magnesia 1～5%, aluminium oxide 1～8%, gluconic acid 2～12%, boric acid 6～20%, sodium metasilicate 1～6%, nonionic surface active agent 1～8% and distilled water are composite to form.
The preparation method who is used for the stabilizing agent of hydrogen peroxide degumming and bleaching of flax of the present invention, by percentage to the quality, with diethylentriamine five methylenephosphonic acids (DTPMP) 5～15%, sepiolite 2～8%, montmorillonite 2～10%, di-iron trioxide 1～6%, magnesia 1～5%, aluminium oxide 1～8%, gluconic acid 2～12%, boric acid 6～20%, sodium metasilicate 1～6%, nonionic surface active agent 1～8% and distilled water mix, and stir, and obtain being used for the stabilizing agent of hydrogen peroxide degumming and bleaching of flax.
The processing step of stabilizing agent when being used for hydrogen peroxide degumming and bleaching of flax that is used for hydrogen peroxide degumming and bleaching of flax of the present invention is: (1) rolls acid, and (2) pad the hydrogen peroxide bleaching liquor, (3) decatize, (4) washing.
