Description
Technical field
The present invention relates to the afterfinish method of suede superfine fiber synthetic leather.
Background technology
In recent years, suede superfine fiber synthetic leather is increasingly liked by consumer, turns into superfine fiber chemical leather
Main product.But with the development of the society, people are required more suede superfine fiber synthetic leather performance and environmental-protecting performance
Add strictly, although traditional C6 and C8 series waterproofing agent can assign super fiber leather good anti-siphon performance, its PFOA contained,
The materials such as PFOS, not only compromise the health of people, and are not easily decomposed；Therefore, the floride-free anti-siphon superfine fibre of environment-friendly type is developed
Synthetic leather is extremely urgent.
Floride-free water-proof aagent is generally the macromolecular of high polymer, when processing thickness is more than 1.0mm super fiber leather or highly dense
When spending super fiber leather, if using direct impregnation method, often occur water-proof aagent be gathered in super fiber leather surface and can not be complete
The sandwich phenomenon of infiltration.Conventional improved method is addition bleeding agent or crosslinking agent.But if adding bleeding agent, although anti-
Water finishing agent penetrating power strengthens, but the surface tension increase of super fiber leather, and this causes the effect of anti-siphon to decline；If add crosslinking
Agent, although more water-proof aagents can be made to be linked in super fiber leather, increase anti-siphon effect, cause the folding line of suede to become
Difference, feel reduce.
The content of the invention
It is an object of the invention to provide a kind of anti-siphon final finishing side of the environment-friendly type for suede superfine fiber synthetic leather
Method, the defects of to overcome prior art to exist.
The method of the present invention, comprises the following steps：
(1) superfine fiber chemical leather is immersed in anti-siphon treatment fluid, padded, after padding, the liquid carrying rate of super fiber leather is
40%~70%；
Described anti-siphon treatment fluid includes the component of following parts by weight：
PH value is 4~6；
Preparation method is as follows：
Floride-free water-proof aagent, reactive polysiloxanes, water cross-linking agent and water are mixed, then mixed liquor is adjusted with acetic acid
PH, obtain described anti-siphon treatment fluid；
(2) and then by the product of step (1) at 130~160 DEG C 5~10min of drying and processing, then cooled down, received
After rolling up, rubbing the processes such as line, anti-siphon suede superfine fiber synthetic leather is obtained.Described cooling, to wind, rub the processes such as line be known
Technology, reference can be made to document：Synthetic leather technology [M] such as Qu Jianbo Beijing：Chemical Industry Press, 2010. sides recorded
Method；
The floride-free water-proof aagent is cationic active modification resin or hyperbranched dendrimer polymer (such as Shandong
ECO plus, the LZ-XR88 of 3M companies of doffer company) in one kind or arbitrary proportion mixture aqueous solution；
The reactive polysiloxanes are hydrophobic type nonionic silicones (the nano active polysiloxanes of such as Mai Tu company
NFR-A)；
The water cross-linking agent is in aromatic series closed type PIC (such as FU of solar corona company) or active organosilicon
One kind of mesosome (such as adhesion promoter 628 of silok companies) or the mixture of arbitrary proportion.
Preferably, in step (1), the superfine fiber chemical leather after dyeing is immersed in anti-siphon treatment fluid, by 1 leaching 1
Roll, when padding, control the liquid carrying rate of super fiber leather, regulation speed is 2~8m/min；Using oozing for ultrasonic technology enhancing treatment fluid
Permeability, ultrasonic frequency are 50kHz~100kHz.
Suede after dyeing is immersed in anti-siphon treatment fluid by the present invention, in floride-free water-proof aagent, activity poly silicon
Under the multiple action of oxygen alkane and crosslinking agent, strengthen the permeability for the treatment of fluid using ultrasonic technology, what is obtained has good anti-rainbow
Absorption energy suede superfine fiber synthetic leather, and the good folding line of suede and velvet can be assigned, at the same also have it is certain it is grease proofing,
Soil resistance.
The present invention uses ultrasonic technology, and anti-siphon treatment fluid is placed in ultrasonic generator, passes through ultrasonic wave
Effect, accelerates the seepage velocity into matte super fiber leather of water-proof aagent, water-proof aagent is equably penetrated into suede
In the super fiber leather of face.There are the characteristics of following and advantage compared with prior art：First, the present invention uses ultrasonic technology, anti-rainbow
Inhaling inorganic agent equably can penetrate into inside super fiber leather, avoid sandwich phenomenon, improve the anti-siphon effect of matte super fiber leather
Fruit；Second, the present invention uses ultrasonic technology, the seepage velocity of water-proof aagent is accelerated, improves production efficiency；Third,
Hydrophobic type reactive polysiloxanes are added in anti-siphon system, the anti-siphon effect of suede can be improved, and can improves suede
Folding line, increase suede pliability.
Agent of the present invention uses fluorine-free and environment-friendly water-proof aagent and ultrasonic technology without APEO, PFOA and PFOS, obtains
The superfine fiber chemical leather arrived, the anti-siphon effect that dipping 2h maceration extracts climb less than 1cm can be reached, and have good folding line
And velvet, improve the class of suede superfine fiber synthetic leather.
