Description
Technical field
The invention belongs to chemical fields, and in particular to a kind of fabric bleaching agent.
Background technique
The fast development of social, science and technology progress and textile technology, promotes the consumption idea of people constantly, performance and function
Oneself is not able to satisfy the demand of people to the single consumer textile product of energy, and demand of the people to the consumer textile product of high-quality increases year by year
Add, and there is the phenomenon that adding also to be more and more obvious fiber favor.Instrument synthetic fibre-poly- acetic ester fiber is that Sinopec Yizheng Fiber Optical plant is limited
Responsible company is by by the polymerized monomer block polymerization of poly-vinegar fiber and Fypro, the synthetic fibers of new generation of exploitation.It is poly-
Carboxylic acid amide esters fabric water suction is ventilative, moisture absorbing and sweat releasing, antistatic property, thermal stability, in terms of all surmount cotton fabric, give
The impression of people's back to nature, is well received by consumers, but the inherent yellow appearance of fiber make its as bleaching kind or
Light-coloured prods are restricted.So how to make up the defect of poly- polyurethane products, meets end product demand and become and grind at present
The emphasis studied carefully, and making up this defect method the most direct is exactly to bleach to it.
With the continuous development of science and technology, it has been found that, sodium chlorite used at present, sodium hypochlorite, peroxidating
Although the bleaching agents such as hydrogen bactericidal effect is first-class, fabric can be had damage, bleaching efficiency is low, therefore, produces one kind
Bleaching effect is good and necessary to the undamaged fabric bleaching agent of fabric.
Summary of the invention
The technical problems to be solved by the invention：Fabric can be damaged for the strong basicity bleaching liquid of current hydrogen peroxide
Wound, the low problem of bleaching efficiency provide a kind of fabric bleaching agent.
In order to solve the above technical problems, the present invention is using technical solution as described below：
A kind of fabric bleaching agent includes following component according to parts by weight, hydrogen peroxide that 15 ~ 30 parts of mass fractions are 30%, 3 ~ 6
Part sodium metasilicate, 4 ~ 8 parts of glyceryl triacetates, 2 ~ 5 parts of sodium pyrophosphates, 4 ~ 7 parts of heterogeneous ten alcohol polyoxyethylene ethers, which is characterized in that
It further include 20 ~ 30 parts of bleach activating auxiliary agents, 25 ~ 35 parts of cationic additives；
The preparation method of the bleach activating auxiliary agent, includes the following steps：
（1）Take diethanol amine in mass ratio 1：50 are added anhydrous methanol, are stirred in 25 ~ 30 DEG C, add diethanol amine matter
The methyl acrylate of 2 ~ 4 times of amount, is warming up to 35 ~ 40 DEG C and is stirred, obtain stirring mixture；
（2）Take trimethylolpropane in mass ratio 60：1 is added p-methyl benzenesulfonic acid, is warming up to 110 ~ 115 DEG C, adds three hydroxyl first
The stirring mixture of 2 ~ 4 times of base propane quality, is stirred in 120 ~ 125 DEG C, and vacuum distillation obtains vacuum distillation object, takes decompression
Distillation in mass ratio 1：7 are added toluene, are stirred in 90 ~ 100 DEG C, add the acetic acid of 3 ~ 5 times of amount of substance of vacuum distillation,
It is stirred in 100 ~ 110 DEG C to get bleaching assistant；
The preparation method of the cationic additive, includes the following steps：
A. gamma-chloropropylmethyldimethoxysilane in mass ratio 1 is taken：2 are added diethylamine, are stirred in 100 ~ 110 DEG C, cold
But to room temperature, filtering takes filtrate decompression to distill, must be evaporated under reduced pressure object A, takes vacuum distillation object A in mass ratio 1：6 are added without water beetle
Alcohol is stirred in 40 ~ 45 DEG C, obtains mixture A, takes epoxychloropropane in mass ratio 1：5 are added dehydrated alcohol, in 35 ~ 40 DEG C
It is stirred, obtains mixture B, take mixture B in mass ratio 2：1 is added mixture A, and in 45 ~ 55 DEG C of 5 ~ 7h of heat preservation, rotation is steamed
Hair, obtains rotary evaporation object；
B. gelatin in mass ratio 1 is taken：15 are added distilled water, are stirred 50 ~ 60min, are warming up to 50 ~ 55 DEG C, add gelatin
The rotary evaporation object of quality 90 ~ 95%, adjust pH to 10 ~ 11, be stirred in 55 ~ 60 DEG C, adjust pH to 7 ~ 7.2 to get sun from
Sub- additive.
The present invention is compared with other methods, and advantageous effects are：
（1）Using diethanol and methyl acrylate as raw material esterification occurs for the present invention, and trimethylolpropane is added, so that end hydroxyl
The terminal hydroxy group of base dissaving polymer is constantly and carboxyl reacts to form ester group, the HOO of ester group and decomposing hydrogen dioxide solution generation-Parent occurs
Core replaces, and generates Peracetic acid anion, and Peracetic acid anion is to compare H2O2More active bleaching agent, Peracetic acid yin from
Son is more and more, can generate blanching effect under low temperature, low ph condition, to improve bleaching efficiency, hydroxyl is contained in product,
This keeps the bleach activating auxiliary agent of synthesis more easily soluble in water, and the activity of activator is stronger, improves the bleaching effect of hydrogen peroxide
More preferably, bleaching time is shortened, to alleviate the damage to fabric；
（2）The present invention is using gamma-chloropropylmethyldimethoxysilane and diethylamine as raw material, and synthesis contains in a high pressure reaction kettle
The siloxanes and epoxychloropropane of tertiary amine groups are raw material, and quaternization reaction occurs in methanol solvate, generates a kind of cationic
It is reacted with gelatin, quaternary ammonium cationic groups is introduced into gelatin chain by bleaching additive, and preparation has bacteriostasis antibiosis
The cationic protein of performance, one side cationic peroxy acid have bigger affinity, cation to the cotton fiber of anion
There are Electrostatic Absorption between cotton fiber, the electronegativity on cotton fiber is reduced, while increasing between fabric and anionic dye
Active force significantly improves the dyeability of anion-active dye, is conducive to peroxy acid and is adsorbed on cotton fabric, improves on fabric
Peroxide acid concentration improves bleaching effect to efficiently use hydrogen peroxide, and on the other hand, the product that glutin continues hydrolysis is
The mixture of amino acid and peptide, glutin and its hydrolysate are a kind of good chelating agents, contain amino in their molecules
With carboxyl isopolarity group, these groups all contain lonely pair of electronics, have coordinating, and it is anti-complexing to occur with heavy metal ion
It answers, generates the complex compound with reticular structure, the metal ion in drift bath is fettered, and invalid point to hydrogen peroxide is reduced
Solution, while the quaternary ammonium salt group introduced has antibacterial bacteriostatic effect to cotton fabric, increases antibacterial fabric performance；
（3）The present invention adds stabilization additives sodium pyrophosphate, sodium metasilicate, reduces hydrogen peroxide decomposition rate, sodium metasilicate is double
Play a part of stabilizer in oxygen water liquid lime chloride, refining agent heterogeneous ten alcohol polyoxyethylene ether be added, on the one hand make hydrogen peroxide and
The bleaching component of Peracetic acid is seeped into the shortest time in cotton fiber surface and gap, on the other hand, so that taking off from fabric
It is dispersed in working solution from the impurity to get off, improves bleaching efficiency, a fairly large number of glyceryl triacetate of ester group is added
For substrate, auxiliary bleaching, and the product completely after reaction is glycerol and acetic acid, is all degradable material, environmental sound.
