Polyester Filaments

Fig. 19.11A,B presents, as an example, data of drawing series of nylon 6 and polyester filaments (Van der Meer, 1970). The additional data for the polyester (polyethylene terephthalate) are given in Table 19.8 by stretching the Young modulus increases by a factor 8 and the tensile strength by a factor 5.5 (Fig. 19.13).

Toray Saehan is a synthetic fibre business, which started operations in 1999. The company is a joint venture between Japan s Toray and South Korea s Saehan companies. Toray Saehan has three major business areas polyester base film and film processing, polyester filament and polypropylene and polyester spunbond, nonwoven fabric. [Pg.133]

Non-slip finishes are often used with under-constmcted fabrics to compensate for the reduced yam count and to achieve acceptable physical properties. Lining and pocketing fabrics made with smooth synthetic filaments are finished with friction enhancers combined with durable press agents, water repellents or hand modifiers to prevent seam slippage. Umbrella fabrics made from nylon or polyester filament yams are treated with friction enhancers and water repellents. The properties of any woven fabric with long floats can usually be improved with nonslip finishes. In particular, Jacquard upholstery fabrics with long floats are... [Pg.117]

Recommended for flat and texturised polyester filament yarns which are to be woven on projectile or air-jet looms. Suitable for low twist yarns providing excellent protection against fil-amentation and producing warps of first class weavability. [Pg.45]

Antistatic coning oil fo use on nylon and polyester filament yarns. Most effective on carpet yarns. [Pg.324]

Spunbonded media (Fig. 10.48c) is made from continuous polyester filaments. During manufacturing, polyester is melted, extruded, spun, and drawn to form laminated webs. The webs are rolled, thermally bonded, and embossed to form sheets. Spunbonded media feature a hard, slick surface that is ideal for increasing the filtering efficiency and, at the same time, retains little dust during cleaning. Also, spunbonded media provides 30 to 50 % more surface area than other filter media. [Pg.447]

B) Dissymmetric structure of fibers is obtained by spinning two component filaments side by side or utilizing the different swellings of the layers formed by the core and skin present in polyester filaments. [Pg.97]

Polyester is a thermoplastic material and is able to change its shape after the application of heat. Therefore PET granulate is the base material for polyester filaments that are converted to yams for the production of fabrics. This polyester (known as PES in textile production terminology) is, without... [Pg.56]
