Description
Technical field
Crease proofing agent and preparation and pad method belong to Fabric Wrinkle Resistant Finish technical field.
Background technique
N-methylol amide resinoid is a kind of industrial commonly used crease proofing agent, is knitted for cellulose fibre
The wrinkle proofing of object can get good anti-wrinkle effect, wherein being most widely used with 2D resin.Knitting after 2D resin finishing
Object has good durable press finish effect.But it has the following deficiencies:
1, formaldehyde can be released in use and storage process, endanger people's health；
2, keep fabric yellowing serious after arranging；
3, fabric intensity reduces larger after arranging.
In traditional treatment process, also frequently as crease proofing agent, citric acid has safe and non-toxic, at low cost citric acid
Honest and clean advantage.But in use there is also finish fabric yellowing, strongly decline serious disadvantage.
So the wrinkle proofing of fabric in the prior art is how in the case where safe and non-toxic, proof strength is not lost, and is knitted
Object not yellowing is a urgent problem.
Summary of the invention
The technical problem to be solved by the present invention is overcome the deficiencies of the prior art and provide fabric intensity after a kind of arrangement it is high,
The stable crease proofing agent of color keep and preparation and pad method.
The technical solution adopted by the present invention to solve the technical problems is: the crease proofing agent, which is characterized in that composition packet
It includes: glyoxal Modified Citric Acid, fatty alcohol polyoxyethylene ether, crosslinking agent and catalyst；Wherein glyoxal Modified Citric Acid is whole

L, concentration of the crosslinking agent in finishing agent are 6 g/L ~ 15g/L, and concentration of the catalyst in finishing agent is the g/ of 24 g/L ~ 37
L。
The present inventor is modified citric acid using glyoxal, and use according to the design feature of citric acid
Catalyst, the additive for improving anti-wrinkle effect can be cooperateed with, anti-crease finishing working solution is collectively constituted.Cotton fabric is arranged, it can
Reach following effect: creasy recovery angle reaches 239.3 ° or more, and strength retention is 62.43% or more, and whiteness is 86.1 or more.
Concentration of the glyoxal Modified Citric Acid in finishing agent is 60 g/L ~ 62g/L, aliphatic alcohol polyethenoxy
Concentration of the ether in finishing agent is the g/L of 1.8 g/L ~ 2.1, and concentration of the crosslinking agent in finishing agent is 9.5 g/L ~ 10.6g/
L, concentration of the catalyst in finishing agent are the g/L of 28 g/L ~ 33.The present invention provides a kind of preferred composition and ratio, Neng Gouda
To optimum efficiency of the invention, creasy recovery angle, strength retention, whiteness reach optimum state of the invention.
The catalyst is sodium citrate, magnesium chloride, sodium hypophosphite or sodium nitrate.Available catalyst packet in the present invention
It includes above-mentioned several, can guarantee the function of the main component of glyoxal Modified Citric Acid that the present invention synthesizes, reach on wrinkle resistance
With the comparable effect of 2D resin.
Preferably, the catalyst is sodium nitrate.Sodium nitrate is the most preferred catalyst of the present invention, is synthesized with the present invention
The main component of glyoxal Modified Citric Acid synergistic effect highest, effect be much higher than other catalyst.
The preparation method of above-mentioned crease proofing agent, which is characterized in that preparation step are as follows:
1) citric acid is reacted 5.7 under 38 DEG C ~ 43 DEG C of stirring condition according to the molar ratio of 1:5.4 ~ 6.6 with glyoxal
Glyoxal Modified Citric Acid is made in ~ 6.5h；
2) glyoxal Modified Citric Acid, fatty alcohol polyoxyethylene ether, crosslinking agent and catalyst are prepared by dosage to obtain the final product.
Citric acid and glyoxal belong to formaldehydeless component, and product, will not harmful to human without having to worry about Form aldehyde release problem
Health.There are two highly polar aldehyde radicals in glyoxal selected by the present invention, show electropositive, and the hydroxyl oxygen on citric acid has lone electron
It is right, it can react generate hemiacetal or acetal between the two, generate a kind of longer mixing synthesis finishing agent of new strand,
After crosslinking agent, the auxiliary agents such as catalyst are added, creasy recovery angle reaches 239.3 ° or more, and strength retention is white 62.43% or more
Degree is 86.1 or more.
Preferably, the citric acid and glyoxal according to molar ratio be 1:5.9 ~ 6.1.The preferred molar ratio of the two is closed
Mixing hemiacetal or acetal in synthesis finishing agent at rear formation has a certain ratio, and the effect of finishing fluid can be made especially prominent.
A kind of pad method using above-mentioned finishing agent, which is characterized in that including padding finishing agent step, soft-bake step,
Step is baked, finishing agent used in the padding finishing agent step is the described in any item crease proofing agents of claim 1 ~ 4,
