The high tech uses of polypropylene (French) (Le polypropylene dans ses emplois high tech)

The consumption of polyefin has increased sharply over the last few years. It is found in various forms according to the application. The consumption of fibres has increased mainly as coverstock for hygiene products and in the carpet velvet areas, and they are also used for the making of big bags. Filaments are used as velvet yarns for ca..

Kanebo Gohsen develops new antibacterial polyester filament

Kanebo Gohsen, Ltd. has developed a polyester filament yarn with kneaded-in antibacterial agents for the first time in the textile industry and will start marketing from spring/summer 1998 items under the brand Live Fresh P Neo. The new filament has an ozone sterilization mechanism in which a very small amount of activating enzymes is con..

Asbestos and its potential substitutes: aramid fibres (Serbocroatian) (Azbest injegovipotencijalni supstitutenti-aramidna vlakna)

Owing to its structure asbestos possesses the whole complex of characteristics which are very important for different fields of usage. The harmful effect f ashestos dust for the health of people, as well as the forbidding of its usage in industrial countries, led to the appearance of new synthetic fibers of specific structure, among which..

Shingosen: Past, Present, and Future.

The first generation of synthetic silk fabrics (1960-1971) were designed to reproduce the luster, drape, and high bending stiffness of silk. The principal technology used during the generation was the extrusion of polyester filament with trilobal cross se

Properties of Fabrics Made from Cotton/Polyethylene Blend Yarns.

Researchers processed a fine denier Dyneema polyethylene staple fiber and manufactured cotton-rich intimate blend yarns, bicomponent yarns, and fabrics containing different blend ratios of cotton and Dyneema fibes. The blends were converted into different

Analyses of Shingosen Technology.

Rsearchers studied the properties of shingosen fabrics, which are soft, drapable, and lustrous. They used experimental data to compare the surface mechanical properties of shingosen fabrics with silk and silk-like fabrics. Discrimination analysis using representative parameters of these properties identified four hand groups of shingosen ..

Silver-Coated Nylon Fiber as an Antibacterial Agent.

A study examined the physical properties of a blend of nylon and X-Static silver coated nylon fibers. The blended fibers had bactericidal properties when directly exposed to bacteria. Bacterial survival decreased rapidly and exponentially in ambient temperatures after a 1 hour delay. The rate of bacteria killing increased with increases i..

Effect of Blend Ratio on Structure Properties of Microfibers/Cotton Yarns.

Researchers investigated the effect of yarn structure and blend ratio of ring and open end yarns from mixtures of cotton fibers and polyester microfibers on such yarn properties as strength, uniformity, and elongation. They used a microscope to study the longitudinal and cross sections of the yarns and determine the effect of fiber finene..

Yarn Quality in Mini Jute Mills.

Researchers evaluating the performance of mini jute spinning machines in terms of yarn quality focused on quality ratio, breaking elongation, count and strength variation, unevenness, and imperfections. Although manufacturers of mini jute mills claim they

Wound Yarn Properties with Special Reference to Yarn Imperfections.

A study investigated fiber transfer as the cause of increased yarn hairiness due to yarn winding, particularly for yarns with less than average diameter. Results indicated that small size yarn imperfections increased after winding. Winding tension level did not affect yarn imperfection levels significantly. Lower winding speeds did not ne..
