Ligno-Cellulosic Fibres.

A study examined the structure and properties of various ligno-cellulosic fibers using an infrared method and the conventional chemical method to estimate cellulose content. The infrared method is fast, simple, and environmentally friendly. Chemical metho

Selected Applications of Modern FT-IR Techniques

A textbook discusses selected applications of Fourier transform infrared (FT-IR) systems. A section on fundamental information explores FT-IR systems, scanning conditios, infrared microscopes, attenuated total reflection, multiple internal reflection, diffusion reflection accessories, photoacoustic detectors, fixed angle and variable angl..

PHYSICAL INTERPREATION AND DEVELOPMENT OF ULTRASONIC NONDESTRUCTIVE EVALUATION TECHNIQUE

The physics underlying the interaction of ultrasound with the sample in advanced ultrasonic nondestructive evaluation methods was examined. these methods are used to characterize composites. The properties of complex, three-dimensional composites that limit the ability of ultrasound to detect flaws were identified and characterized. In th..

INFLUENCE OF HARVESTING. GINNING, AND MILL CLEANING SYSTEMS ON THE SPINNING PERFORMANCE OF COTTON

The influence of cotton system processing parameters on fiber properties, spinning performance, and yarn quality was examined by two complementary studies. The first focused on the effects of stripper harvesting and gin cleaning; the second focused on the

MONTEFIBER -- THE EVOLUTION OF ACRYLIC AND POLYESTER MICROFIBERS.

Montefibre is the only European producer capable of supplying the most complete range of polyester and acrylic microfibers in both filament ayrn and staple form. Montefibre's first efforts in decitex reduction can be traced to the development in the 1980s of its Terital Silklike, a polyester filament yarn, and Terital Zero.4, the first Eu..

REVIEW OF COTTON IN AFRICA

The cotton industries in Africa, including Tunisla, Morocco, Francophone Africa, Sourth Africa, Uganda, and Kenya, are reviewed. Tunisia has singificantly increased production since 1981, with the aim of supplying 25 percent of domestic needs by 2000. Production in Morocco is down because of drought and a decrease in guaranteed prices. Lo..

COTTON INCORPORATED DYEING AND FINISHING LABORATORIES.

Cotton Incorporated maintains dyeing and finishing laboratories to develop seasonal color forecasts, special dyeing techniques, and special finishes, and to evaluate dyeing and finishing equipment and procedures. The laboratories are capable of performing such processes as cotton and cotton blend preparation, bleaching, color matching, dy..

METHOD OF PRODUCING HIGH MODULUS POLYMERIC MATERIALS.

BTTG has developed a process that compresses and heats either fiber assembiles or oriented polymers, which results in a sheet that has superior mechanical properties, particularly in the direction transverse to that in which the fibers have been aligned. The process is described in European patent 2,253,420. The compaction pressure during..

VEGETABLE FILAMENT YARN

Technological developments in the production of viscose that are environmentally safe will probably reverse the deownward trend for this fiber. Nuova Rayon Italia of Rieti, Italy, has ploneered the use of some of these developments in producing Rayon FCT 3000 filament yarn at its state-of-the-art facility. The production cycle includes di..

ENCEL -- DEBUT OF A FIBER.

Courtaulds executives describe Tencel as a new, natural luxury fiber for apparel and home fashion. Tencel is made of wood pulp from trees grown on managed forests, thus making it an environmentally freindly fiber. Tencel has the drape and color of rayon, but it is stronger than rayon. It costs about 50 cents more per pound than rayon, whi..
