Abstract
The present invention provides a kind of New-type adjuvants for blue leather wetting, prevent leather from frying the New-type adjuvant in face and the usage of this New-type adjuvant.Contain organic acid compound, fatty alcohol polyoxyethylene ether surfactant, alkyl benzene sulfonate surfactant and calcium ions and magnesium ions chelate in this auxiliary agent.This auxiliary agent is used for the blue leather wetting process of leather industry, blue skin can effectively be made to ease back the folding that disappears, and can chelate calcium and the magnesium salts with reference to corium face and bath foam, make leather hand feeling submissive happy, assists to prevent leather from frying face.It especially puts rewetting of changing long to wet blue and disappears folding effect significantly.
Description
Technical field
The present invention relates to a kind of auxiliary agent field of tanning production, it is more particularly related to a kind of for blue skin
The usage of the auxiliary agent of rewetting and this auxiliary agent.
Background technology
For leather industry as traditional and modern industry, the production, life with people are closely bound up.In order to meet market
Requirement, process hides worker have been devoted to improve leather and fur products quality.In leather making process, the quality of leather is removed and raw material
The quality of skin, the quality of leather material used, the factors such as superior of technique have outside the Pass, also with the grasp and control of each process in technique
System has a very large relationship relationship.
An important procedure of the rewetting of wet blue leather as dyeing and finishing part, has the quality of final leather products important
Influence.Whether wet blue leather rewetting is abundant, is related to absorption of the leather to chemical materials in bath foam to a certain extent, so as to influence
The quality of leather.At present, in order to reduce the pollution to environment, domestic many process hides producers are in addition or import wet blue is made a living
Produce raw material.These wet blue leathers are placed by water squeezing, for a long time or exposure is stood in air, if storage is improper to occur as soon as wet blue leather
Middle large quantity of moisture is lost in, and the combination between collagenous fibres and chromium and collagenous fibres increases, and is hardened so as to cause wet blue leather.In this way
If wet blue leather phenomena such as cannot get preferable return water, the fracture of fried face just would tend to occur, seriously affect the quality of finished leather.Together
When, the wet blue of tannery oneself production is also likely to be present similar situation.Although rewetting is micro- in entire process hides process
Its is micro-, it is easy to be ignored by tanners, but it as one of basic process in process hides, the influence to leather quality is not
Appearance is neglected.Wet blue leather after the main purpose of rewetting is to make wet blue leather after water squeezing, shaving or places for a long time fully absorbs
Moisture makes water-filling between leather fiber, can mutually be slided between the evacuation of leather fiber, fiber and fiber, in this way, being conducive to afterwards
Material used is swapped with being wrapped in the moisture of leather fiber surface in process；Rewetting process can remove in leather base and surface
Neutral salt, shavings etc.；In addition, the condition such as pH value of different skin bases before retanning etc. is adjusted by this process, make different batches
Or the condition of the skin base of different sources production reaches consistent, it is whole conducive to gained leather in the processes such as subsequent dyeing retanning and stuffing
Consistency, prevent dyeing defect, aberration etc.；Meanwhile rewetting also play supplement degreasing effect, slough leather fiber on and
The grease not removed completely between fiber or because mechanical processing is stained on the oily substances such as the machine oil on leather, is more conducive to leather fiber
It is hydrophilic, conducive to the abundant rewetting of wet blue leather.In short, rewetting is laid the groundwork for processes such as subsequent retanning, dyeing, wet blue leather rewetting
The quality of effect affects absorption of the leather to chemical materials such as retanning agent, dyestuffs, so as to affect the quality of finished leather and class.Cause
This rewetting could also say that process more crucial in leather making process.
At present, domestic manufacturer mostly is rare simple, effective, the practical method for solving the stiff dead elephant of discounting of blue skin
And auxiliary agent, handle this problem using only some surfactants.But this can not really solve to have occurred between fiber more serious
Bonding, i.e., cannot really play the role of rewetting and disappear folding.
Invention content
The object of the present invention is to provide a kind of auxiliary agent for blue leather wetting, to solve in the prior art above-mentioned ask
Topic, this rewetting additive performance of the invention is good, and blue skin can effectively be made to ease back the folding that disappears, and can remove with reference to corium face calcium and
Magnesium salts makes leather hand feeling submissive happy, and assistance prevents leather from frying face.
The auxiliary agent for blue leather wetting of the present invention is composed of the following components by weight percentage：
(a) organic acid compound 52%~60%
(b) fatty alcohol polyoxyethylene ether surfactant 13%~20%
(c) alkyl benzene sulfonate surfactant 5%~15%
(d) calcium ions and magnesium ions chelate 10%~20%
Organic acid compound can provide low ph value, high degree of mechanical can be avoided to act on the damage to surface, and from assisting chromium
Absorption, avoiding the loss of chromium during return water influences resultant leather quality amplification quantity high concentration chrome wastewater side by side, pollutes environment.
Surfactant can guarantee good permeability, and dry blue skin can be made effectively to absorb moisture, filled between fiber
Divide and unfold, and the grease not removed completely can be removed or because mechanical processing is stained on the oily substances such as the machine oil on leather, make leather fiber
It is more conducively hydrophilic, conducive to blue leather wetting process.
Calcium ions and magnesium ions chelate can chelate calcium ions and magnesium ions unnet in material bath foam and skin sample, and not only demineralized water is more advantageous
It absorbs water in blue leather wetting, it is ensured that leather softness grain is careful.
Specific embodiment
With reference to the composition contained by this auxiliary agent and application method, by embodiment, the present invention is further described.
Embodiment 1
A kind of auxiliary agent for blue leather wetting, composition composition are：Adipic acid 52%, paregal O -1513%, dodecane
Base benzene sulfonic acid sodium salt 15%, sodium tripolyphosphate 20% are sufficiently mixed after grinding.By following technique to be allowed to dry long hard indigo plant skin into
Row rewetting process, and carry out Experimental Comparison with common rewetting auxiliary agent such as peregal, penetrating agent JFC, degreasing agent etc..
Added material utilization amount is based on the quality of pigskin shaving wet blue leather
Rinsing or rewetting 32~38 DEG C of 200% temperature of distillation
Formic acid (85%) 0.3%
0.7%40~60min of rewetting auxiliary agent
