Abstract:
Porous, permeable particles of meta-aramid can be chlorinated or brominated to produce antimicrobial and detoxifying particles for use in applications such as, but not limited to, nonwoven webs, paper, textiles, absorbent articles, healthcare products, paints, filter materials, powder coatings, clear coatings, molded plastic articles, binders for fibrous materials, and the like. The particles can be charged with halogen before or after incorporation into the application medium. The particles can contain blends of meta-aramid with other polymers such as, but not limited to, cellulose, cellulose acetate, polyurethane, and the like. The particles will be effective at inactivation of pathogenic and odor-causing microorganisms and toxic chemical agents. The particles, which contain N-halamine units, have unexpected resistance to ultraviolet light degradation.

International Classification:
C08G 6316
US Classification:
528272
Abstract:
A method for decreasing the amount of ether as a by-product in polyesters (for example terephthalic-based) by initially utilizing a deficient amount of a glycol (for example, ethylene glycol) in the early reaction stages and utilizing an excess of the glycol in the final or end stages. The polyesters produced are of better quality, have a high melting point, possess increased thermal stability, and yield improved fiber properties.
Rotably Driven Braiding Machine With Third Yarns Carried And Delivered By Stationary Carriages About A Braiding Point

Assignee:
Auburn University - Auburn University AL
International Classification:
D04C 348 D04C 340
US Classification:
87 44
Abstract:
A braiding machine which operates to deliver a first set of yarns about a vertical axis along a first plane to a braiding point and a second set of yarns about the vertical axis along a second plane located above the first plane to the braiding point and a third set of yarns stationarily arranged about the vertical axis for delivery along a third plane intermediate of the first and second planes to the braiding point. The machine includes an interlacing mechanism which is associated with each yarn of the third set of yarns and including a rotating interlacing member. The interlacing member of each interlacing mechanism is operative to successively engage and carry the first yarns out of the first plane above said third plane over a third yarn of the third yarns and to carry the second yarns out of the second plane below the third plane beneath a third yarn of the third yarns causing each of the first and second yarns to successively interlace with each of the third yarns during their movement about the vertical axis. This positioning action between the first, second, and third yarns forming a braided fabric of superior strength and stability.

International Classification:
D04C 100
US Classification:
87 9
Abstract:
An axially stable tubular braided fabric comprising a longitudinal set of yarns extending longitudinally of the fabric, a first set of yarns arranged substantially along a first cylindrical plane and at an angle relative to the longitudinal yarns and a second set of yarns arranged substantially along a second cylindrical plane and transversely of the first set of yarns. The yarns of the longitudinal set are passed consecutively over one and under the other of the yarns of the first and second sets interlocking these yarns together in an axially stable position with the yarns of the first set predominating the outer surface and the yarns of the second set predominating the inner surface.

Abstract:
A process for reducing the glycol ether content in polyesters involves adding a glycol to a polyester oligomer solution prior to polymerization, distilling the oligomer solution to remove vapor containing the glycol as well as the glycol ether, and polymerizing the solution to produce a polyester containing a reduced glycol ether content.
