Description
Technical field
Crease proofing agent and preparation and pad method, belong to Fabric Wrinkle Resistant Finish technical field.
Background technology
N-methylol amide resinoid is a kind of industrial commonly used crease proofing agent, is knitted for cellulose fibre
The wrinkle proofing of thing, can obtain good anti-wrinkle effect, wherein being most widely used with 2D resins.Through knitting after 2D resin finishings
Thing has good durable press finish effect.But there is following defect：
1st, formaldehyde can be discharged in use and storage process, the health of people is endangered；
2nd, make fabric yellowing serious after arranging；
3rd, fabric intensity reduction is larger after arranging.
In traditional handling process, also frequently as crease proofing agent, citric acid has safety non-toxic, low cost to citric acid
Honest and clean advantage.But finish fabric yellowing is there is also in use, strongly decline serious shortcoming.
So the wrinkle proofing of fabric in the prior art how proof strength is not lost in the case of safety non-toxic, knit
Thing not yellowing is a urgent problem.
The content of the invention
The technical problem to be solved in the present invention is：Overcome the deficiencies in the prior art, there is provided one kind arrange after fabric intensity it is high,
The crease proofing agent and preparation and pad method of color keep stabilization.
The technical solution adopted for the present invention to solve the technical problems is：The crease proofing agent, it is characterised in that composition bag
Include：Glyoxal Modified Citric Acid, AEO, crosslinking agent and catalyst；Wherein glyoxal Modified Citric Acid is whole
Concentration in reason agent is 55 g/L ~ 65g/L, and concentration of the AEO in finishing agent is 1.3 g/L ~ 2.6g/
L, concentration of the crosslinking agent in finishing agent is 6 g/L ~ 15g/L, and concentration of the catalyst in finishing agent is 24 g/L ~ 37 g/
L。
The present inventor is modified using glyoxal according to the design feature of citric acid to citric acid, and is used
Catalyst, the additive for improving anti-wrinkle effect can be cooperateed with, anti-crease finishing working solution is collectively constituted.Bafta is arranged, can
Reach following effect：Creasy recovery angle reaches more than 239.3 °, and more than 62.43%, whiteness is more than 86.1 for strength retention.
Concentration of the described glyoxal Modified Citric Acid in finishing agent is 60 g/L ~ 62g/L, aliphatic alcohol polyethenoxy
Concentration of the ether in finishing agent is 1.8 g/L ~ 2.1 g/L, and concentration of the crosslinking agent in finishing agent is 9.5 g/L ~ 10.6g/
L, concentration of the catalyst in finishing agent is 28 g/L ~ 33 g/L.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.
Described catalyst is sodium citrate, magnesium chloride, sodium hypophosphite or sodium nitrate.Available catalyst bag in the present invention
Include above-mentioned several, can guarantee that the function of the main component of glyoxal Modified Citric Acid of present invention synthesis, reached on wrinkle resistance
The effect suitable with 2D resins.
Preferably, described catalyst is sodium nitrate.Sodium nitrate is the present invention most preferably catalyst, is synthesized with the present invention
The main component of glyoxal Modified Citric Acid synergy highest, effect be far above other catalyst.
The preparation method of above-mentioned crease proofing agent, it is characterised in that preparation process is：
1）By citric acid and glyoxal according to 1：5.4 ~ 6.6 mol ratio reacts 5.7 under 38 DEG C ~ 43 DEG C of stirring condition ~
6.5h is obtained glyoxal Modified Citric Acid；
2）Glyoxal Modified Citric Acid, AEO, crosslinking agent and catalyst are prepared by consumption and is obtained 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, the hydroxyl oxygen on citric acid has lone electron
Right, can react generation hemiacetal or acetal between the two, generate a kind of new strand mixing synthesis finishing agent more long,
After adding crosslinking agent, the auxiliary agent such as catalyst, creasy recovery angle reaches more than 239.3 °, strength retention more than 62.43%, in vain
Degree is more than 86.1.
Preferably, described citric acid and glyoxal according to mol ratio be 1：5.9~6.1.Both close at preferred mol ratio
Hemiacetal or acetal have a certain ratio into rear formation mixing synthesis finishing agent, and the effect of dressing liquid can be made especially to protrude.
A kind of pad method using above-mentioned finishing agent, it is characterised in that including padding finishing agent step, soft-bake step,
Step is baked, the finishing agent used by described padding finishing agent step is the crease proofing agent described in any one of claim 1 ~ 4,
Padding finishing agent step simultaneously soaks two roll process, pick-up 70% ~ 80% using two；The baking temperature of described soft-bake step is 98 DEG C
~ 105 DEG C, the time is baked for 2 min ~ 3min；The described baking temperature for baking step is 140 DEG C ~ 180 DEG C, and the time that bakes is 1
min~3min。
The use of this dressing liquid can be improved to more than 239.3 ° the creasy recovery angle of finish fabric（Former cloth creasy recovery angle
It is 147.0 °, is 188.5 ° through the wrinkle recovery angle of woven fabrics using viscoelasticity theory of Citric Acid Finishing）.Anti-wrinkle effect can it is suitable with 2D resins even more
It is good.In addition, improving fabric yellowing phenomenon（Former cloth whiteness is 88.8, and through the fabric whiteness 80.2 of Citric Acid Finishing, this synthesis is whole
Reason agent fabric whiteness 86.1）.
Preferably, the described baking temperature for baking step is 158 DEG C ~ 163 DEG C, bakes the time for 145s ~ 153s.Correctly
Use this dressing liquid ensure that the effect of finish fabric, preferably bake condition the most suitable with the characteristic of product of the present invention
Should, effect reaches most preferably.
Preferably, the pick-up 77% ~ 78% of two described two roll process of leaching.
Preferably, the drying temperature of described soft-bake step is 100 DEG C, and drying time is 2 min.
Preferred padding finishing liquid and preliminary drying technique, more adapt to preferably condition is baked.
Crosslinking agent preferably uses Suzhou Liansheng Chemicals Co., Ltd. LS-710 type crosslinking agents.Can show in the present invention
Well adapting to property.
Compared with prior art, crease proofing agent of the invention and preparation method are had an advantageous effect in that：The present invention
Inventor according to the design feature of citric acid, citric acid is modified using glyoxal, and use can cooperate with raising it is crease-resistant
The catalyst of effect, additive, collectively constitute anti-crease finishing working solution.Citric acid and glyoxal belong to formaldehydeless component, produce
Product will not be detrimental to health without having to worry about Form aldehyde release problem.There are two highly polar aldehyde in glyoxal selected by the present invention
Base, shows electropositive, and the hydroxyl oxygen on citric acid has lone electron pair, and can react generation hemiacetal or acetal between the two, raw
Synthesize finishing agent into a kind of mixing more long of new strand, after adding the auxiliary agents such as crosslinking agent, catalyst, creasy recovery angle reaches
