Description
Technical field
The present invention relates to synthetic fibers bleaching technology fields, and in particular to a kind of polyamidoester fibre and pure spin, blended knits
The acid oxygen bleaching agent of object and method for bleaching.
Background technique
Polyesteramide is the copolymer of polyamide and terephthalic acid (TPA), ethylene glycol, is that comprehensive performance surmounts natural fiber
Novel super imitative cotton fiber.Polyamidoester fibre has obtained many applications in pure spinning, blended yarn weaved fabric exploitation at present, due to poly-
In faint yellow, pure spinning or blended fabric need first to be bleached carboxylic acid amide esters before dye light color or sensitive color.Since polyesteramide is resistance to
Alkalinity is poor, and the usually used hydrogen peroxide alkalinity bleaching process (pH value is 10~11) to cotton, fiber crops bleaching of dyeing and finishing factory is not only right
Polyesteramide does not have bleaching effect, can damage fiber instead；Sodium hypochlorite, sub- chlorine drift can bleach polyesteramide, but want to equipment
Ask high, device therefor is necessary for corrosion resistant stainless steel material, and generating chlorine, chlorine dioxide etc. in bleaching process has human body
The gas of murder by poisoning, and production cost is higher；And the protein fibres such as silk, hair are soluble in hypochlorite solutions, spandex floats molten in chlorine
Intensity can decline in liquid and color becomes more yellow, can not bleach, therefore the fiber mixed fabrics such as polyesteramide and silk, hair, spandex
Method cannot be floated with chlorine to be bleached.
The master thesis " peroxyacetic acid bleaching of alkali-sensitive new chemical fibre " of University Of Suzhou uses hydrogen peroxide/tetra-
The method that peracetic acid bleaches soybean fiber, milk fibre, acid fiber by polylactic is generated in the solution of acetyl ethylenediamine, solves fiber
The alkaline bleaching of dioxygen present in damage problem, but higher cost, and hydrogen peroxide bleaches polyesteramine ester under alkaline condition
In vain.Japan Patent JP 63195333 for compound material composition protein fibre or albumen acrylonitrile copolymer fiber and
Native cellulose fibre, by bleaching alkaline solution oxidative bleaching agent such as hydrogen peroxide, or mixtures thereof Peracetic acid compared with
Low temperature prevents injury protein matter fiber.Hydrogen peroxide alkaline process is bad to polyesteramide bleaching effect.Sinopec instrument
A kind of method for bleaching polyesteramide staple fiber and fabric with Peracetic acid, but peroxide is illustrated in sign chemical fibre Co., Ltd hair
Acetic acid usage amount is big when acetic acid bleaching agent is prepared, and bleaching cost is relatively high, and needs to be catalyzed with the concentrated sulfuric acid in process for preparation
Agent.And the concentrated sulfuric acid belongs to and easily makes quick-fried harmful influence, buying, management process are cumbersome, therefore it is larger in general dyeing & printing enterprise to promote difficulty.
A kind of polyesteramide bleaching agent for unchlorine has been invented by Shanghai Textile research institute, by hydrogen peroxide, acetic acid, urea, catalyst, activation
The composition bleaching agent process for preparation such as agent, stabilizer, infiltration scouring agent, water are complicated, and auxiliary agent uses more, bleaching, cleaning cost
Relatively high, bleach stability is poor, in dyeing & printing enterprise Difficulty.Silk, the hair introduced in other patents or document bleach work
Skill is not suitable for polyesteramide bleaching yet.
Summary of the invention
It is an object of the invention to overcome the shortage of prior art, provide it is a kind of be suitable for polyamidoester fibre and its it is pure spin,
The acid oxygen bleaching agent of blended fabric and method for bleaching are re-dubbed acid drift using the mixing such as hydrogen peroxide and organic acid, stabilizer
White dose, then it is made into certain density bleaching liquid together to polyamidoester fibre, uni-material fabric and various fibers with deionized water
Blended fabric is bleached, and the whiteness of bleach product is made to can satisfy rear road process requirements.It is big to match acid oxygen bleaching agent stability
Big to improve, bleaching effect is unaffected within storage 60 days or more.
The purpose of the present invention can be achieved through the following technical solutions:
It is a kind of for polyamidoester fibre and it is pure spin, the acid oxygen bleaching agent of blended fabric, which includes peroxide
Change hydrogen solution, organic acid and hydrogen peroxide stabilizer.
In some preferred technical solutions: the hydrogen peroxide stabilizer is this smooth one hundred spy WSL, and the organic acid is first
Acid or acetic acid.
In some preferred technical solutions: the mass concentration of the hydrogenperoxide steam generator is 20~50%, peroxidating
The mass ratio of hydrogen solution, organic acid and hydrogen peroxide stabilizer is 100~300:50~200:1~30.It is further preferred: peroxidating
The mass ratio of hydrogen, organic acid and hydrogen peroxide stabilizer is 200~300:100~200:10~30.
A method of bleached using above-mentioned acid oxygen bleaching agent: this method is in the acid oxygen bleaching of standing >=48h
Deionized water is added in agent, sequentially adds activator and scouring agent later, preparation obtains bleaching agent aqueous solution；To be bleached is gathered
Amide ester fiber and it is pure spin, blended fabric is put into the bleaching agent aqueous solution and is bleached, then take out bleaching sample into
Row neutralizes and goes acid elution, enzyme wash, wash, dries to get the sample of whiteness is met.
In some preferred technical solutions: the activator is tetraacetyl ethylene diamine；The scouring agent is poly- for isomery alcohol
The composition of one or both of ethylene oxide ether or ethoxylated alkyl sulfate.
In some preferred technical solutions: the concentration of the acidity oxygen bleaching agent in bleaching agent aqueous solution be 40g/L~
400g/L, concentration of the activator in bleaching agent aqueous solution are 0.01%~1.0%, and scouring agent is dense in bleaching agent aqueous solution
Degree is 0~1.0%.
In some preferred technical solutions: the temperature of bleaching is 85 DEG C~120 DEG C, time of bleaching be 0.5h~
2.5h, the pH value of bleaching agent aqueous solution are 2~4.
In other preferred technical solutions: the liquid lime chloride bath raio of infusion process bleaching is 1:2.5~1:20, padding method
The pick-up rate of (long vehicle method) bleaching is 50%~90%.
In some preferred technical solutions: neutralizing and removing the detergent of acid elution process is that sodium carbonate or sodium hydroxide are molten
Liquid, concentration are 2g/L~10g/L；Enzyme washes enzyme lotion used using hydrogen peroxide catabolic enzyme, and concentration is 0.5g/L~5g/L.
Beneficial effects of the present invention:
1, acid oxygen bleaching agent process for preparation of the invention is simple, and stability is good, and bleaching effect does not decline within storage 60 days or more；
Being configured to certain density bleaching agent aqueous solution with deionized water, scouring agent, activating agent etc. can be to polyamidoester fibre, pure spinning
It fabric and its is bleached with the fabric of the various fiber blends such as cotton, hair, silk, fiber crops, spandex, reaches satisfied bleaching effect, floated
White technique is environmentally protective, and bleaching cost is lower.
2,53 are greater than to the CIE whiteness of pure polyesteramide fabric bleaching, polyesteramide and spandex blended fabric bleach whiteness
Greater than 50, the CIE whiteness of other fiber mixed fabrics bleachings such as polyesteramide staple fiber and its cotton, hair, silk, fiber crops is greater than 68, drift
For white fabric intensity drop less than 15%, bleaching process is small to the strength damage of polyesteramide and other fibers, sets to conventional dyeing and finishing
It is standby not generate corrosion, it is non-hazardous to people and environment；
3, the present invention can to avoid with bleaching liquid when chlorine drift method bleaching to the dissolution of hair, silk fiber and caused by fabric it is broken
Bad, hydrogen peroxide is small compared with sodium hypochlorite, sodium chlorite to the destruction of dyestuff, therefore also dechlorination is not clean right after avoidable oxygen bleaching
Road dyeing course has an impact afterwards.
4, the gas to the toxic effect of human body is not generated in bleaching process, conventional equipment for dyeing and finishing will not be generated rotten
Erosion does not constitute environment and endangers.
