  • Patent number: 5348772
    Abstract: The invention relates to the use of the amino groups created on the surface of a polymer material, such as a polypropylene film, by an electric treatment, notably a cold plasma, under nitrogen atmosphere, for accelerating the grafting of the polymer material by impregnating the latter with a bath containing a vinyl type unsaturated monomer comprising a carbonyl group in .alpha. of the double vinyl bond, such as an acrylic monomer.
    Type: Grant
    Filed: June 2, 1992
    Date of Patent: September 20, 1994
    Assignee: Institut Textile de France
    Inventors: Odile Demuth, Daniel Wattiez, Jacques Maguin, Jean C. Brosse, Fabienne Poncin-Epaillard, Bruno Chevet
  • Patent number: 5152896
    Abstract: The invention relates to the use of grafted celluloses, in fibrous form, particularly paper, non-woven web, flock, yarn, woven fabric, comprising quaternary ammonium functions, for eliminating humic substances and nitrates contained in natural water or industrial sewage.The grafted cellulose is for example obtained by radical grafting with the aid of a non-saturated monomer with quaternary ammonium function, particularly quaternized diethyl-amino-ethyl methacrylate.Its capacity is greater than or equal to 0.2 meq/g.

    Inventors: Michel Mazet, Isabelle Rigaudie, Daniel Wattiez, Roger Chatelin, Jean-Francois Combes, Louis Gavet
  • Patent number: 5068113
    Abstract: The fibrous polymeric material based on polyvinyl chloride contains at least one antiseptic mercury derivative distributed in its polymeric structure in the form of a substantially molecular and practically non-releasable dispersion.The preferred mercury derivatives have the following general formula: ##STR1## in which Y is H or HgX. If the concentration of the derivative is equal to at least 0.5% by weight, relative to the chlorofiber, the latter has a permanent antiseptic character.This material is obtained by incorporating the above-mentioned derivative into the collodion when the chlorofiber is spun.

  • Patent number: 4931577
    Abstract: The novel antiseptic mercurial derivatives according to the invention have at least one benzene ring and comprise: a) at least one radical HgX in which X is selected from F,Cl,Br, I, OH, CH.sub.3 COO, CN, SCN, NO.sub.3, OB(OH).sub.2, b) and, bonded to a benzene ring, at least one group--OR or--COOR in which R is a functional group capable of intervening in a reaction of polymerization or of polyaddition. The preferred derivative is 2-chloromercuri 4-tertiobutyl phenol allyl-ether. They may intervene in grafting reactions for the protection of a polymeric support, or in reactions of copolymerization.

    Assignee: Institut Textile de France
    Inventors: Michel Bourgeois, Roger Chatelin, Daniel Wattiez
  • Patent number: 4627920
    Abstract: The process consists firstly in adding, to the solution, an excess of a polyelectrolyte capable of forming an ionic association with the dissolved substance which it is desired to retain, and then in bringing the solution thus obtained into contact with a material possessing ionic groups which retain the polyelectrolyte by virtue of its ionic groups not associated with the said substance. The solution and the material can be brought into contact either by filtration or by tangential bathing. The polyelectrolyte can be retained either by ion exchange or by a charge repulsion effect.The material is advantageously a fibrous material of which the ionic groups are obtained by grafting.

    Inventors: Roger Chatelin, Jean-Francois Combes, Daniel Wattiez
  • Patent number: 4556721
    Abstract: New mercurobutol derivatives characterized in that they comprise at least one functional group, bonded to the mercurobutol phenol ring, which functional group being capable of intervening in a polymerization or polyaddition reaction, and said derivatives having the bioactive properties of mercurobutol, even after such reaction.These new derivatives can intervene in a grafting operation either as termination agent or a polymerization agent.These new derivatives, when grafted on a support, give it protection against bacteria, mushrooms and other micro-organisms.

    Date of Patent: December 3, 1985
    Assignee: Centre Technique Industriel Styled: Institut Textile
    Inventors: Daniel Wattiez, Roger Chatelin, Michel Bourgeois
  • Patent number: 4494264
    Abstract: The invention relates to an element permitting to simultaneously wash in the same bath two types of textile articles, the articles of the first type being dyed with dyes liable to run in the washing bath and to settle on the articles of the second type. The element according to the invention is in the form of a filtering envelope inside which one of the types of textile articles is enclosed, the envelope being made in a material having more tinctorial affinity towards the dyes liable to run in the bath than the articles of the second type.

  • Patent number: 3962054
    Abstract: A process for the treatment of cellulosic textile materials comprising the following successive steps: effecting grafting of the cellulose textile material with a monomer which, when formed into a polymer, has the characteristics of an elastomer at ambient temperature; effecting irradiation treatment by ionizing radiation of the grafted cellulose material so as to achieve cross-linking of the grafts formed, thus leading to permanent crease resistant properties; and effecting post-irradiation treatment by storage enabling the cross-linking to be completed.
