Description
Technical field
The invention belongs to fiber or textile dyeing and finishing technical field, and in particular to a kind of coloured animal hair fiber decolouring oxygen
Change catalyst, the invention further relates to the preparation method and application of above-mentioned catalyst.
Background technology
Coloured animal hair fiber, such as：Coloured cashmere, yakwool and camel's hair are important natural protein fibres,
Belong to high-grade textile raw material, wherein coloured cashmere (blue or green suede, purple suede) is particularly precious.Due to coloured animal hair fiber band in itself
There is deeper color, and be rather limited its dyeing process and application.Coloured animal hair fiber is carried out into decolouring processing,
Making up to certain whiteness, and carry out dyeing after decolourizing can obtain chromatic colour color, can significantly improve converted products
Value, with economic benefit higher.
At present, textile printing and dyeing processing industry is for the decolouring current techique of coloured animal hair fiber：Using ferrous salt pair
Pre-process → hydrogen peroxide oxidation decolouring → reducing agent reduction-decolor by decolouring fiber, the technique have operation controllability strong and
The preferable advantage of decolouring fibre whiteness.Most literature report points out that its Basic Mechanism is to carry out pre- place to fiber using ferrous salt
Reason, Fe2+Formed with the pigment in fiber and be complexed, and most of Fe that non-pigmented region is adsorbed in fiber2+By subsequent wash
Remove；In oxidative decoloration, the Fe being complexed by pigment2+Catalytic decomposition to hydrogen peroxide reaches the effect that destruction pigment improves whiteness
Really；The destruction of pigment is remained in passing through reducing agent in reduction-decolor to fiber, and by chelating agent to remaining iron in the fibre
The chelating of ion comes off, and further improves the whiteness of decolouring fiber.
Using Fe2+To the catalytic decomposition of hydrogen peroxide, the decolouring bleaching effect for reaching coloured animal hair fiber is a lot
Open report, such as：Publication No. CN1381641, entitled a kind of method for decolouring yak hair, it is disclosed that using sulfuric acid
Ferrous, tartar emetic and Nacl carry out pre-treatment to yakwool fiber and wash, and carry out oxygen using hydrogen peroxide, sodium pyrophosphate afterwards
Change and bleach and wash, then carry out reducing bleach and brighten and wash with brightening agent, decolouring yakwool has preferably whiteness；Publication number
It is CN103243543A, entitled a kind of discoloration method of coloured cashmere loose fiber, it is disclosed that coloured cashmere
Dipping decoloration process, specially：Step A, degreasing is carried out using degreasing agent, formaldehyde and sodium carbonate to coloured cashmere；B is walked
Suddenly, oxidation bleaching is carried out to the cashmere through step A degreasing using tetraacetyl ethylene diamine, hydrogen peroxide, shield suede agent and sodium chloride, is gone forward side by side
Row washing；Step C, using ferrous sulfate, sodium hydrosulfite, sodium chloride, fluorescent whitening agent with shield suede agent to the cashmere bleached through step B
Carry out reduction-oxidation；D steps, are washed with ammoniacal liquor using hydrogen peroxide to carrying out oxygen through step C reduction-oxidation cashmere；The invention can be improved
The decolouring whiteness of coloured cashmere, and reduce the degree that cashmere uses rear its colour changed into yellow for a long time.
Directly coloured animal hair fiber is processed using ferrous salt, Fe2+With the polar group shape in fiber pigment
While into relatively stable chelation structure, Fe2+With-the NH in fiber macromolecular chain2,-COOH isopolarities group can also form network
Close structure, the Fe being complexed in like fashion2+Obviously cannot be completely removed by follow-up washing；Additionally, using ferrous salt to dynamic
Thing hair fiber is processed, and physics, the Fe of chemisorbed are passed through present in fiber2+It is in the suds and can not be thoroughly gone
Remove, i.e., the Fe of member-retaining portion complexing and non-complexing in the macromolecular chain in fiber non-pigmented region2+.Rank is bleached in hydrogen peroxide oxidation
Section, Fe in fiber2+(including pigment and the complexing of fiber macromolecular chain and the Fe of non-complexing2+) to the catalytic decomposition of hydrogen peroxide, make color
Plain structure destruction reaches bleaching effect, while making fiber macromolecular chain be subject to Oxidative demage, stretches the strength of decolouring fiber, fracture
Rate long even fibre length has largely loses.Animal origin is entered using ferrous salt directly for being had its source in for the problem
Row treatment, Fe2+To fiber pigment complexing synchronous with macromolecular chain and there is physics, chemisorbed, i.e. Fe2+Check colors
The targeting complexing degree of element is not high, causes its targeting catalytic decomposition efficiency to hydrogen peroxide in pigment regions to reduce, for this
Problem, there is presently no effective research report for solving and exemplary applications.

In the coloured animal hair fiber decolouring oxidation catalyst of the present invention and preparation method and application, one of its key content
It is using the moderate complexing agent of complexing power and ferrous salt react preparing the moderate ferrous ion complexing body of stability
It is oxidation catalyst；The two of key content are the surface active agent compositions in the catalyst, and catalyst can be promoted to apply rank
Absorption, diffusion and complexing of the section to fiber, and fiber is played a protective role and subsequent oxidation bleaching effect is improved.
Report animal hair fiber pigment to Fe in existing document2+Complexing power be better than fiber macromolecular chain polar group
Group, using coloured animal hair fiber decolouring oxidation catalyst (complex system catalyst) of the invention to coloured animal hair fiber
When being pre-processed, fiber pigment progressively replaces the complexing agent Fe in catalyst2+Generation complex reaction, fiber macromolecular chain polarity
Group is weaker for the metalepsis of catalyst complexing agent, so as to strengthen Fe2+Targeting to pigment is complexed degree, strengthens Fe2+
To the targeting catalyticing decomposition action of fiber oxidation decolouring link hydrogen peroxide；Additionally, absorption (residual) coloured animal in the fibre
The Fe of hair fiber decolouring oxidation catalyst2+To be complexed, body form is present and ferrous salt directly processes the free Fe of absorption2+Phase
Than：Catalyticing decomposition action to hydrogen peroxide is relatively weak, can weaken Oxidative demage of the non-pigmented region decomposing hydrogen dioxide solution to fiber.
By the synergy of surfactant in the above-mentioned effect of complex system and catalyst, using coloured animal hair of the invention
The decolouring that fiber decolouring oxidation catalyst is applied to coloured animal hair fiber can significantly improve Fe2+Utilization ratio, and substantially
Low-fiber damage is dropped, and making strength, elongation at break and the fibre length of decolouring fiber has more obvious improvement.
