Abstract
The present invention relates to a kind of reduction cleaner, its preparation method and application for synthetic fibers, by weight, its composition of raw materials is as follows：250~350 parts；30~80 parts；
Description
Technical field
The present invention relates to a kind of reduction cleaner, its preparation method and application for synthetic fibers.
Background technology
After terylene and its blend fabric disperse dyeing, in order to lift colorfastness, it usually needs reduced
Cleaning.Reduction cleaner relatively conventional at present is caustic soda and sodium hydrosulfite, and its principle is will be scattered using the reproducibility of sodium hydrosulfite
Dyestuff color development system is destroyed, so as to reach removal loose colour, lifts the purpose of color fastness.
Originally, reduction cleaning is carried out to terylene with alkaline sodium hydrosulfite and possesses greater advantage, but Environmental Protection Situation it is increasingly serious,
Also show rapidly under the background that production safety management is increasingly strict and printing and dyeing enterprise profit increasingly declines, the drawbacks of sodium hydrosulfite.
Sodium hydrosulfite is primarily present following shortcoming when in use：
(1) sodium hydrosulfite understands spontaneous combustion, understands automatic heating especially after moisture absorption and burns, and the warehouse of storage sodium hydrosulfite occurs repeatedly
Fire.
(2) sodium hydrosulfite when in use, easily releases sulfur dioxide gas, causes workshop condition to pollute, and damages workers ' health,
At the same time severe working environment improves the recruitment cost of enterprise.
(3) sodium hydrosulfite is unstable at high temperature, optimum cleaning temperature no more than 80 DEG C, otherwise can decompose rapidly and
Failure.
(5) storage stability of sodium hydrosulfite is very poor, and exposure will be decomposed in atmosphere under cryogenic conditions, cause active ingredient
Constantly decline.
(6) according to standard GB/T 6844-86《Dangerous cargo is classified numbers with the name of an article》Regulation, sodium hydrosulfite belongs to one-level
Dangerous when wet, therefore it has higher risk in transit and cost of transportation.
How to solve the above problems, make terylene reduction cleaning technique become environmental protection, efficiently, be vast dyeing and finishing worker urgently
The problem of research and solution.
The content of the invention
The technical problems to be solved by the invention be to provide a kind of environment-friendly high-efficiency for synthetic fibers reduction cleaner,
Its preparation method and application.
To solve above technical problem, the present invention is adopted the following technical scheme that：
It is an object of the present invention to provide a kind of reduction cleaner for synthetic fibers, by weight, its raw material
Formula is as follows：

R2、R3Independently be selected from carbon number be 0~5 between straight or branched alkyl.
Preferably, by weight, its composition of raw materials is as follows：
Preferably, described R1For selected from-R4-R5, R4To be the straight chained alkyl between 1~4, R selected from carbon number5For choosing
From amino, carboxyl,Any of.It is further preferable that R4For normal-butyl, R5For amino, i.e.,For lysine.
Preferably, described R2、R3It is the alkyl between 0~2 independently to be and be selected from carbon number.It is further preferable that
For glyoxal,Ethylene glycol.
Preferably, described mol ratio of metal acetate is selected from any of magnesium acetate, zinc acetate, calcium acetate, tin acetate.
Preferably, the molecular weight of described polyethylene glycol is 400~4000.
It is a further object to provide a kind of preparation method of the described reduction cleaner for synthetic fibers,
Will be describedDescribedWith it is describedAt 20~40 DEG C
30~60min of lower reaction, then adds described sodium borohydride, continues to react 30~60min, then adds described to benzene two
It is formic acid dimethyl ester and/or described DMIP, described Sodium Dimethyl Isophthalate-5-sulfonate, described
Polyethylene glycol, described p-methyl benzenesulfonic acid and described mol ratio of metal acetate, be warming up to 150~185 DEG C keep 180~
250min, is continuously heating to 220~230 DEG C of 60~90min of holding, is then -0.08~-0.1MP in vacuum, temperature is
230~280 DEG C of 120~180min of insulation, aggregate into block copolymer, are cooled to blowing after 100~120 DEG C, produce described go back
Former cleaning agent.
Specifically, the number-average molecular weight of described block copolymer is 10000~18000.
It is clear that third object of the present invention is to provide a kind of reduction of described reduction cleaner after synthetic dyeing
The application washed in step.
The beneficial effects of the present invention are:
The applicant achieves breakthrough in the field, successfully developed by research for many years and constantly practice
Reduction cleaner-speed of terylene novel green washs treasured, and it has advantages below compared with traditional sodium hydrosulfite：
(1) cleaning performance can match in excellence or beauty with sodium hydrosulfite, or even on some disperse dyes, its cleaning performance meeting to loose colour
More than sodium hydrosulfite.
(2) Use Limitation insist on long, cleaning it is abundant, will not rapidly be failed because of high temperature.
(3) stabilization after water or moisture absorption is met, will not decompose and discharge fuel gas and corrosive gas, in the absence of carcinogenic fragrance
Amine and environmental hormone.
(4) more severe storage environment and transportation environment can be subjected to, is true with relatively low cost of transportation and risk
Positive environmental protection, heavy duty detergent printing and dyeing assistant.
