Description
Technical field
The present invention relates to the method for bleaching of a kind of fabric bleaching liquid and fabric, particularly relate to the method for bleaching of a kind of victoria blended spinning fabric bleaching liquid and victoria blended spinning fabric.
Background technology
In weave dyeing and finishing technique, fabric is after kiering, and on fabric, the natural and artificial impurity of major part removes, and capillary effect significantly improves, and can meet the processing request of some kinds.But to light figured cloth, the painting cloth class of BLEACHED FABRIC and lovely luster, also need to improve whiteness, therefore need to remove the pigment on fabric further, make fabric pure whiter.Though fabric is through kiering besides, especially normal pressure decatize kiering, still have partial impurities such as cotton seed hulls to fail entirely to remove, by the effect of bleaching agent, these impurity can remove completely.
Cotton dyeing factory widely uses the oxidative bleaches such as hypochlorite, hydrogen peroxide.To cotton and cotton fabric bleaching, peracid compound as perboric acid receive, peracetic acid, sodium percarbonate etc. are also even application, sodium chlorite is used for the bleaching of synthetic fiber and BLENDED FABRIC thereof.Usually floated referred to as chlorine by hypochlorite bleaching, hydrogen peroxide bleaching is referred to as oxygen bleaching, and chlorite bleaching floats referred to as Asia.
(1) hypochlorite bleaching
Conventional hypochlorite has bleaching powder and clorox two kinds.Bleaching powder is that chlorine and calcium hydroxide effect form, and if logical chlorine is in milk of lime, can obtain the bleaching powder doubled containing active ingredient; Logical chlorine in soda bath, then can obtain clorox.In bleaching powder and bleaching powder, active ingredient is calcium hypochlorite, and total effect is not as clorox.Cotton dyeing factory larger is at present normal oneself manufactures clorox, or buys clorox for bleaching to neighbouring chemical plant, and bleaching powder is difficult to obtain the small-sized printing and dyeing mill in area of clorox for small city or rural area.Bleaching powder price is more expensive, uses less.
Sodium hypochlorite bleaching technology and equipment is comparatively simple, is used for COTTON FABRIC and victoria blended spinning fabric bleaching, sometimes also bleaches for polyester cotton.But the bleaching of the protein fibre such as silk, wool can not be used for, because clorox has destruction to protein fibre, and make fiber yellowing.
(2) hydrogen peroxide bleaching
Hydrogen peroxide also claims hydrogen peroxide.Better with the fabric whiteness of hydrogen peroxide bleaching, pure color light, not easily yellowing during storage, is widely used in the bleaching of cotton fabric.Oxygen bleaching has larger adaptability than chlorine drift.
(3) chlorite bleaching
The great advantage that sodium chlorate is used for when COTTON FABRIC is bleached is under the condition not damaging fiber, can destroy pigment and impurity.Sodium chlorite is again the good bleaching agent of chemical fibre, and the retention of whiteness of BLEACHED FABRIC is better than the fabric of chlorine drift and oxygen bleaching, but sodium chlorite price is more expensive, strong to metal protection, by titanium or titanium alloy etc materials, and need produce poisonous ClO in sub-drift process
2gas, equipment need have good sealing, therefore in use, is subject to a definite limitation.
Summary of the invention
Technical problem to be solved by this invention is to provide the method for bleaching of a kind of victoria blended spinning fabric bleaching liquid and victoria blended spinning fabric.The method flow process is simple, is suitable for large production; Less to fabric strength damage, environmental protection.
For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions:
A kind of victoria blended spinning fabric bleaching liquid, is made up of following components in mass portion:
Adopt the method that this area is general, above-mentioned each raw material is dissolved in the water, mixes and can obtain this victoria blended spinning fabric bleaching liquid.
Here is the basic introduction of part material of the present invention, for the NaOH of this area routine, hydrogen peroxide and water, does not obviously need to be explained further again.
Potassium borate, English name: Potassium borate.CAS accession number: 1332-77-0.
[1-(4-amino-2-oxopyrimidin-1-base)-3-hydroxy propane-2-base] oxygen methylphosphonic acid, No. CAS: 113852-37-2.Molecular structural formula, as follows:
Acrylic acid maleic acid, is called for short AA/MA, No. CAS: 26677-99-6.
1,5-anhydrous grape sugar alcohol, another name: 1,5-acid anhydride-D-D-sorbite, CAS accession number: 154-58-5, English name: D-Glucitol.
4-(2-oyloxyethoxy in ninth of the ten Heavenly Stems ketonic oxygen base) benzene sulfonic acid sodium salt, molecular structural formula is as follows:
4-(2-oyloxyethoxy in ninth of the ten Heavenly Stems ketonic oxygen base) benzene sulfonic acid sodium salt, molecule is made up of two parts, and its one end is a longer nonpolar hydrocarbon chain, i.e. hydrophobic group; The other end is shorter polar group, i.e. a hydrophilic group, is a kind of surfactant of benzenesulfonates.
Tetraacetyl ethylene diamine, No. CAS: 10543-57-4, No. EC: 234-123-8, be called for short NOBS, English name: N, N, N', N'-Tetraacetylethylenediamine.
Boron compound potassium borate and chelating agent [1-(4-amino-2-oxopyrimidin-1-base)-3-hydroxy propane-2-base] oxygen methylphosphonic acid, acrylic acid maleic acid, 1, the synergies such as 5-anhydrous grape sugar alcohol, can act in hydrogen peroxide and free metal, catch trace metal ion, improve hydrogen peroxide stability in the solution in bleaching process, thus bleaching effect of the present invention can be improved to a greater degree.Amazingly be, bleach-activating 4-(2-oyloxyethoxy in ninth of the ten Heavenly Stems ketonic oxygen base) benzene sulfonic acid sodium salt in the present invention, the composite use of tetraacetyl ethylene diamine, bleaching effect can be improved further, and can effectively suppress the breakage of fabric and fade.
Victoria blended spinning fabric bleaching liquid of the present invention, can adopt the conventional method of this area to bleach fabric, as filling-steaming process, pressurization boiling process, and the similar approach such as the infusion process within the scope of 60-100 DEG C.
Further,
Present invention also offers a kind of method for bleaching of victoria blended spinning fabric, comprise and pad bleaching liquor, decatize and water-washing step,
