Abstract:
Antitoxic fibers and fibrous media contain impregnated material including an antitoxin. A method for producing antitoxic fibers and fibrous media includes impregnating a fibrous media by dipping in a dipping solution containing a concentrate of an antitoxin to form a fiber with impregnated material including an antitoxin.
Abstract:
The present invention provides, inter alia, durable and regenerable microbiocidal textiles and methods for preparing such textiles. Such textiles can be readily prepared using a wet finishing process to covalently attach a heterocyclic N- halamine to a cellulose based material or other polymeric material. Once prepared, the textiles of the present invention have a broad spectrum of biocidal activity against pathogenic microorganisms. Moreover, the biocidal activity of such textiles can be regenerated by washing with a halogenated solution.
Abstract:
Keratin-containing fabric is treated by exposing it to a fluorine-containing gas for a relatively short time, for example 60 seconds or substantially less, by passing the fabric continuously through an atmosphere containing fluorine gas. The fluorine content of the gas to which the fabric is exposed can be relatively low, for example 3 %. The fluorinated fabric may be treated with a polymer such as an amino polysiloxane, and when so treated is protected against shrinkage and maintains good fabric mechanical properties.
Abstract:
A process for preparing a nonflammable, linear, nongraphitic carbonaceous fiber having improved elongatability by heat treating a linear, stabilized polymeric precursor material fiber in a relaxed condition and without subjecting the fiber to tension or stress in an inert non-oxidizing atmosphere at a temperature above 525 DEG C to irreversibly heat set said fiber, and a linear carbonaceous fiber having improved elongatability of from 3 to 9 percent and a tenacity of from 2 to 7 g/d.
Abstract:
L'invention concerne l'utilisation de carbones sous-fluorés en tant que lubrifiant solide. Ces carbones sous-fluorés comprennent à la fois des domaines de carbone fluoré de structure du type (CF)n et des domaines de carbone de structure graphitique non fluoré, sous forme de poudre, en tant que lubrifiant solide. L'invention trouve application dans le domaine des lubrifiants solides.
Abstract:
The present invention is directed to methods of forming sidewall-functionalized carbon nanotubes, wherein such functionalized carbon nanotubes have hydroxyl-terminated moieties covalently attached to their sidewalls. Generally, such methods involve chemistry on carbon nanotubes that have first been fluorinated. In some embodiments, fluorinated carbon nanotubes ("fluoronanotubes") are reacted with mono-metal salts of a dialcohol, MO-R-OH, where M is a metal and R is hydrocarbon or other organic chain and/or ring structural unit. In such embodiments, -O-R-OH displaces -F on the nanotube, the fluorine leaving as MF. Generally, such mono-metal salts are formed in situ by the addition of MOH to one or more dialcohols in which the fluoronanotubes have been dispersed. In some embodiments, fluoronanotubes are reacted with amino alcohols, such as being of the type H2N-R-OH, wherein -N(H)-R-OH displaces -F on the nanotube, the fluorine leaving as HF.
Abstract:
Biocidal polyamide materials such as deodorant and/or biocidal Nylon3 polyamide fibers, fabrics and surfaces and biocidal Aramid (such as Kevlar3 and Nomex3) fibers, fabrics and surfaces, and methods of preparation. Heterocyclic N-halamine precursor moieties are covalently linked to the polyamide material. The fabrics and/or fibers thereafter obtain antimicrobial activity after washing with a halogenated solution to convert the heterocyclic precursor moieties into heterocyclic N-halamines. The antimicrobial activity against pathogenic microorganism can be repeatedly regenerated by washings with a halogenated solution.
