PFCs comprise a large group of compounds characterized by a fully fluorinated hydrophobic linear carbon chain attached to one or more hydrophilic head. PFCs repel both water and oil, and are therefore ideal chemicals for surface treatments. These compounds have been used for many industrial applications including stain repellents (such as Teflon), textile, paints, waxes, polishes, electronics, adhesives, and food packaging [1]. [Pg.4]

Commercial products, used widely for the treatment of textiles, mainly apparel, soft furnishings, and carpets, are known under the trade names Scotchgard (3M), Teflon (DuPont), Asahigard (Asahi Glass), and Unidyne (Daikin). This subject is reviewed in detail in Reference 24. [Pg.150]

Fluorochemicals. Fluorochemicals are the most important class of repellents for textiles. They are the only repellents that provide repellency to water, waterborne stains, oil, oilbome stains, and oily particulates. The various products have a variety of repellency and durabiHty properties for certain fabrics, and the specific compositions ate proprietary. The first company to market fluorochemical repellents was 3M iu the 1950s (Scotchgard Fabric Protector), followed by DuPont (Zepel and Teflon Fabric Protectors). Several other companies such as Autalux Corporation, Ciba Specialties, Eastern Color Chemical, Glo-Tex Chemicals, IVAX Industries, Liadley Laboratories, NICCA U.S.A, Piedmont Chemical, Sedgefield Specialties, Sequa Chemicals, and Yorkshire Pat-Chem also market such finishes (17). Fluorochemical finish appHcation areas include rainwear, upholstery, drapery, and automotive fabrics, roofing materials, and carpeting. Both natural and synthetic textile fibers can be treated. [Pg.307]

DuPont registered the Teflon trademark in 1945 and released Its first Teflon products a year later. Since then the non-stick coating has become a household staple on kitchen cookware, in baking sprays, and as a stain repellantfor fabrics and textiles. [Pg.195]

The plastics industry and all the products made from plastics are almost entirely dependent on chemicals extracted or produced from hydrocarbons. This includes not only the familiar materials such as polyethylene, polypropylene, polyvinyl chloride (PVC), epoxies, nylon, polyesters, polycarbonate. Teflon and Plexiglas, but also includes a large portion of materials made from rubber and a diverse group of other materials formulated from polymers such as tape, glue, ink, waterproofing, wax, and polishes. Virtually all the synthetic fibers used in textile products, Orion , Dacron , Nylon and polyesters are made from polymers based on hydrocarbons. [Pg.24]

Wide-span buildings using textile material were of less interest in the 1980s. While most architects and engineers were looking to produce constructions in concrete, there were still some projects, like the 1982 Hubert M. Humphrey Metrodome in Minneapolis, which were constructed using Teflon-coated fibreglass. The inner pressure that was necessary to stabilize the form made it necessary to use airlocks, which was not a perfect situation... [Pg.261]

Textiles used as fabric fagades are commonly a coated mesh. This allows a view out and reduces energy consumption while providing solar protection (Armijos, 2008). The most common types are PVC-coated polyester manufactured into a coated or extruded product, PTFE (poly-tetrafluoroethylene or Teflon) coated flbreglass mesh, and ETFE (ethylene-tetrafluoroethylene) foils. [Pg.399]

The natural polymers mentioned above are synthesized and grown into fibers by nature. Cotton, wool and silk are some examples. Wood is produced similarly, but not being in a form suitable for use as a textile fiber, it must be chemically modified to produce an appropriate solution, which can then be extruded into a fiber. Rayon and cellulose acetate are examples of this pro-cess.1 Synthetic materials, on the other hand, must be first polymerized into chains, by finking small molecules together end to end, and then extruded into fibers. Chains are built by either a condensation or an addition process. Nylon and polyester are examples of polymers synthesized by condensation, whereas polyethylene, polypropylene, acrylic and polytetrafluoroethylene (Teflon ) are some examples of polymers prepared by the addition process. [Pg.189]

Textile test specimens vary widely in both physical and chemical characteristics however, most samples can be characterized without any special preparation. Usual samples include fibers, yarns, and fabrics that can be presented directly to most commercial spectrophotometers. It is important to realize that variability within the textile sample is fairly high. A statistical sampling scheme is necessary to achieve a fair representation of a production lot. In the case of fabric samples, several layers of fabric or an appropriate background, such as ceramic or Teflon tile, will be necessary to create diffuse reflectance or transreflectance signals. Textile yarns and fabrics have bidirectional orientations and, hence, either a rotational sample cup or at least three rotations of the stationary cup are necessary to compensate for the differences owing to the sample orientation. Another difficulty with the textile fabrics is that they are usually dyed with various dark or pastel colors. Black and gray samples are more difficult to measure however, using appropriate procedure dyed fabrics are analyzed quite frequently. It is not uncommon to use separate calibrations for (i) white or pastel, (ii) medium shade, and (iii) dark color samples. [Pg.438]
