Definitions
- the present invention relates to the treatment of certain polymeric materials, in particular of textile materials such as cotton, in particular with a view to giving them lasting antiseptic properties. These are precisely non-keratin materials, having little or no thiol functions or disulphide bridges in their polymer structure; among textile materials, wool is therefore excluded.
- the invention also relates to the materials obtained by the treatment and having lasting antiseptic properties.
- French treatment No. 83.00442 has already described a treatment intended to give a material antiseptic properties in which said polymeric material is subjected to a grafting reaction in which also intervenes a derivative of mercurobutol, having a functional group, linked to phenolic nucleus of mercurobutol, and capable of intervening in a polymerization or polyaddition reaction.
- the mercurobutol derivative is placed in the graft, generally at the end of the chain, and provides the material thus grafted with antiseptic properties.
- it is the functional group, linked to the phenolic nucleus of mercurobutol, which intervenes.
- Patent GB.A.1.178.307 discloses a process for rendering an article containing keratin autosterile. This process known consists first of all in treating the article with solutions such as ammonium thioglycolate in order to break the bisulphide or cystenic bridges of keratin in order to produce sulphydryl groups, then in a second stage in treating the article with a solution a metal salt in order to replace the hydrogen ions of the sulphydryl group with the corresponding metal ions.
- the metal ions are chosen for their antiseptic action (silver, bismuth, copper or mercury).
- This process is specific to keratin polymeric materials, having thiol functions or disulphide bridges in their structure.
- the process of the invention consists, the material having in its polymeric structure no or few thiol functions and / or bisulphide bridges, in treating said material so as to fix in its polymeric structure thiol functions then in putting said material thus treated in the presence of a solution containing a heavy metal atom.
- a solution containing a heavy metal atom This will be in particular a solution containing mercury or a mercurial derivative having an antiseptic activity.
- the heavy metallic atom in the ionic state, for example mercury, silver, bismuth, copper either as such or in the form of a derivative, binds to the thiol functions which have been created in the polymer structure of the material during the first step in the process.
- the polymeric material being a polyhydroxylated polymer, in particular cotton and fibranne
- the first treatment for the creation of thiol functions consists in causing the ethylene sulphide to act.
- the mercurial derivative in solution is a derivative having antiseptic properties. It can be in particular mercurobutol or a derivative of mercurobutol, in particular bromomercuri-2 tertio-butyl-4 phenol allyl ether. It can be another mercurial derivative such as mercury phenyl borate or mercurescein, or another mercurial derivative recognized by the pharmacopoeia.
- a non-keratin polymeric material having lasting antiseptic properties, obtained according to the aforementioned process, and which comprises in its polymeric structure thiol functions linked to a heavy metal atom, alone or in the form of a derivative, having an antiseptic activity.
- mercury or mercury derivatives recognized by the pharmacopoeia.
- the content of heavy metal atom, as such or in the form of a derivative having antiseptic properties is at most 1 ⁇ by weight.
- the process of the invention can also be used for the extraction of heavy metals from charged baths.
- the aim is to extract said metals or to purify the bath without particularly seeking the properties of the material obtained.
- a piece of cotton is first treated with 20% sodium hydroxide for 30 minutes, before being rinsed with water, then with alcohol. It is then treated at 80 ° C in ethylene sulfide for 40 hours. After successive rinses with benzene, alcohol and water, the quantity of thiol functions created on the cotton is measured.
- the rate of thiol functions obtained is of the order of 9%.
- the piece of cotton is then immersed in a solution alcoholic mercurobutol at 50 g / l, expressed at a rate of 90%, for 10 minutes, rinsed with alcohol then with water at room temperature, then dried.
- the mercurobutol content by weight of cotton is 2.8%.
- Example 1 is reproduced, but the cotton is impregnated in a jigger for a one hour cycle with an excess solution of mercurobutol.
- the mercurobutol content by weight of cotton is 11.5%.
- a piece of cotton is first impregnated in the scarf with 4% soda. It is then treated at 80 ° C in ethylene sulfide for 20 minutes. After rinsing, it is brought into contact in a jigger with an aqueous solution of 100 mg / l of mercurobutol solubilized by a surfactant which is for example sodium lauryl sulphate in an amount of 40 g / l.
- a surfactant which is for example sodium lauryl sulphate in an amount of 40 g / l.
