The present invention provides durable and regenerable microbiocidal textiles and methods for preparing same. Such textiles can be readily prepared using a wet finishing process to covalently attach a hetercyclic 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.
摘要:
A process for preparing a non-flammable linear non-graphitic carbonaceous polymeric fiber, yarn or tow having improved elongability containing the step of heat treating a linear stabilized polymeric fiber, yarn or tow having an LOI greater than 40 without any substantial tension or stress in an inert non-oxidizing atmosphere at a temperature so as to irreversibly heat set said fiber yarn or tow.
摘要:
This invention relates to a process for improving the water wicking and moisture transport properties of synthetic resins, e.g., fiber form polyamides, polyesters, polyolefins, and polyacrylonitriles, which comprises sulfofluorinating said resins in a self-activating gaseous reaction medium containing from about 0.1-20% by volume elemental fluorine, 0.1-50% by volume of sulfur dioxide, 0-21% by volume oxygen, and the balance inert for providing from 1 .times. 10.sup.-.sup.9 to 1 .times. 10.sup.-.sup.3 milligrams fluorine and sulfur per square centimeter of resin surface.
摘要:
EXCHANGER PACKINGS OF CORRUGATED LAMINATED ASBESTOS THROUGH WHICH GASES ARE PASSED FOR HEAT OR MOISTURE EXCHANGE ARE STRENGTHENED BY DIPPING THE FIBER BOARD SHEETS, OR PACKING FORMED FROM SUCH SHEETS, INTO AN INORGANIC SOLUBLE SALT SOLUTION, THE EXCESS LIQUID BEING DRAINED AND THEN PRECIPITATING THE SALT COMPONENT UPON THEFIBRES OF THE PACKING BY REACTING WITH A GASEOUS MEDIUM. THE INORGANIC SALT IS TYPICALLY WATER GLASS, AND THE PRECIPITATING GAS IS TYPICALLY CARBON DIOXIDE, SULFUR TRIOXIDE, CHLORINE OR THE LIKE.
摘要:
A process for the conversion of thermally stable aromatic polyamide-shaped articles into dimensionally stable fireproof products which involves a constructive heat treatment at elevated temperatures in an elemental halogen-containing atmosphere under carefully controlled conditions.
摘要:
A process for preparing mist, which includes micro/nano solids or liquids, and a process for forming new materials by mist gas discharge, and also an apparatus for forming new materials. The advantages are: as compared to common gases, mists exhibit broader selection range of elements and compounds and broader range of suitable temperature and pressure. Due to the presence of mist AI(m), in a sealed container, the concentration of A in unit volume of mist is far higher than the concentration of A in unit volume of gas. Under specific conditions, the physical/chemical reactions can be carried out more easily, and new materials can be formed with higher efficiency.
