Definitions
- the present invention relates to a method of treating skins and the skins thus treated.
- It relates more particularly to a treatment making it possible to ensure better conservation from a biological point of view thereof, in particular during the process of preparation thereof before or after their tanning.
- products or compositions comprising compounds with antifungal or anti-bacterial action such as, for example, tri or pentachlorophenols, paramethacresol, orthophenyphenol and their sodium salts, benzothiazole derivatives (for example, TCMTB), isothiazolones, metal salts such as zinc or copper salts.
- compounds with antifungal or anti-bacterial action such as, for example, tri or pentachlorophenols, paramethacresol, orthophenyphenol and their sodium salts, benzothiazole derivatives (for example, TCMTB), isothiazolones, metal salts such as zinc or copper salts.
- these products can also be annoying in the development of skins after tanning, for example.
- the object of the invention is in particular to remedy these drawbacks by proposing a method of treating the skins to protect them from fungal or bacterial attacks, capable of being applied at all stages or stages of the method for producing a skin.
- the invention provides a method of treating the skins to protect them from fungal and / or bacterial attacks consisting in treating the latter with a treatment bath comprising at least one salt of lanthanum or of cerium.
- lanthanum or cerium salts any water-soluble salt such as mineral salts such as nitrates, chlorides, sulfates, for example, organic salts or organosulfonic or gluconate salts.
- the lanthanum or cerium salts are organic salts derived from a vinyl carboxylic acid such as, for example, acrylic acid, methacrylic acid.
- the preferred salts of the invention are the lanthanum acrylates and methacrylates.
- the skins are treated with an amount of lanthanum or cerium expressed as oxide advantageously between 0.02% and 1.25%, preferably between 0.04% and 1.25%.
- lanthanum expressed as oxide
- tripe skin skin that is depilated and free of fat and epidermis.
- the salt is a vinyl carboxylic acid salt
- free vinyl carboxylic acid is added to the treatment solution.
- the amount of vinyl anion or of vinyl acid expressed as free vinyl acid is advantageously between 0.5% and 5% of skin in guts, preferably between 1% and 3%.
- This treatment bath can be used alone or in combination with a skin treatment bath, such as for example the pickling, tanning, or pre-tanning baths such as the BSH or BSS baths, described for example in French patent no. 2 610 643 from the Technical Center for Leather Shoes and Leather Goods.
- a skin treatment bath such as for example the pickling, tanning, or pre-tanning baths such as the BSH or BSS baths, described for example in French patent no. 2 610 643 from the Technical Center for Leather Shoes and Leather Goods.
- This antifungal and antibacterial treatment bath is particularly suitable for treating tanned skins in order to preserve them against molds damaging their appearance.
- the treatment bath according to the invention preserves the skin against attack by fungi such as, for example, aspergillus niger, penicillium funiculosum, rhizopus nigricans, trichoderma viride or bacteria bacilus subtilis, escherichia coli.
- fungi such as, for example, aspergillus niger, penicillium funiculosum, rhizopus nigricans, trichoderma viride or bacteria bacilus subtilis, escherichia coli.
- Another advantage of the process of the invention lies in the fact that the treatment agent does not become fixed irreversibly on the skin fiber and therefore can be easily removed by washing.
- lanthanum or cerium are not harmful and therefore can be discharged into waste water.
- the method of the invention can be implemented by any known means and for example by impregnation with a treatment bath by passing through a fuller.
- the invention also relates to skins treated according to the method of the invention and comprising lanthanum and / or cerium.
- the treated skins advantageously comprise from 0.02% to 1.2% of lanthanum or cerium expressed relative to the weight of dry matter, that is to say after drying in a ventilated oven for 6 hours at 105 ° C and drying at this temperature at constant weight.
- the treated skins can also comprise vinyl units either in monomeric form or in polymerized form.
- the skin was divided into strips which were then treated with stabilization baths to obtain B.S.H.
- This stabilization treatment consists in adding to the pickling solution after neutralization 2% (tripe weight) of aluminum polychlorosulfate (i.e. 0.16% expressed as Al2O3) in the form of an aqueous solution having a basicity of 55%, a desulfation rate of 82% and an Al2O3 content of 8.3% obtained according to the process described in European patent application No. 218487.
- aluminum polychlorosulfate i.e. 0.16% expressed as Al2O3
- control strip No. 1 is invaded by mold both in the full-thickness leather and in the split flower.
- Tests of skin contamination by molds were carried out in a PETRI box, on small samples of leather seeded with microbial cells, at the rate of 1 ⁇ 105 cells per cm2 of leather.
- the sample thus seeded is placed in an agar medium poured into a PETRI box and itself seeded with the suspension of corresponding microbial molds.
- the whole is incubated at 30 ° C. in a thermostatically controlled oven.
- a leather tanned with chromium salts and commonly called “wet-blue” leather, is impregnated with a solution containing an antibacterial compound either in accordance with the invention, or by way of comparison with a known compound and commonly used, namely a derivative of benzothiazole marketed under the name "BUSAN".
- the lanthanum content, expressed as lanthanum oxide, or the busan content is 0.4%
- the results are collated in the attached table: ANTIBACTERIAL COMPOSITION % INVASION OF THE SAMPLE AFTER 3 DAYS 6 DAYS 12 DAYS 16 DAYS 27 DAYS - 50% 100% 100% 100% 100% LANTHANE XYLENE SULFONATE 10% 60% 80% 80% 80% LANTHANE GLUCONATE 5% 60% 80% 80% 80% LANTHANE SULFATE 5% 80% 80% 100% 100% LANTHANE ACRYLATE 0% 5% 40% 40% 60% LANTHANE ACRYLATE + ACRYLIC ACID 0% 5% 5% 15% BUSAN 0% 0% 0% 0% 0% 0% 0% 0% 0% 0% 0%
