Dacron thread

Polyesters Right now, you are probably using at least five things that are made from polyesters. Your clothes probably have some Dacron polyester fiber in them, and they are almost certainly sewn with Dacron thread. Ancient computers used floppy disks made of Mylar , and the optical film in your DVD is made of Mylar . Some of the electronics in your cell phone are probably potted (covered and insulated from shock) in Glyptal polyester resin. The soft drink in your hand probably came in a plastic bottle that was blow-molded from polyethylene terephthalate) resin, better known as PET. 

The rest of the cage struts are covered by tubular-knitted porous polypropylene cloth. The orifice cloth is made from siliconized multi-filament Dacron thread which together with... 

Since the major glycol loss is by entrainment, any design or operating action which reduces this item can result in a considerable improvement in plant economics. Neal et al. (1989) describe a case in which loss from a TEG contactor was reduced from about 9 Ib/MMscf to about 0.009 Ib/MMscf by replacing a standard 4-in.-thick mesh pad made of 0.01 l-in.-diame-ter 304 stainless steel wire with a density of 9 Ib/fl by a 6-in.-thick pad containing fine multifilament dacron thread knitted in with the wire and incorporating a draining feature. 

Fibers are thin threads produced by extruding a molten polymer through small holes in a die, or spinneret. The fibers are then cooled and drawn out, which orients the crystallite regions along the axis of the fiber and adds considerable tensile strength (Figure 31.3). Nylon, Dacron, and polyethylene all have the semicrystalline structure necessary for drawing into oriented fibers. 

Like PET, which further became more and more popular under various trade names (Dacron in USA, Rhodergon in France, Dallon in Russia and European Eastern countries), PTFE was initially used as thread, which could be woven or knitted to obtain vascular prostheses. These resulting woven devices, in which two sets of threads, respectively called weft and warp, cross each other perpendicularly, are known to easily fray near anastomoses. For knitted devices, in... 

Below the black thread at the top, the fibers are acetate rayon (cellulose di- or triacetate, SEF (Monsanto s modacylic), Amel (cellulose triacetate), cotton, Creslan (polyacrylonitrile). Dacron 54 and 64 (polyester without and with a brightener), nylon 6.6 (polyamide), Orion 75 (polyacrylonitrile), silk (polyamide), polypropylene, viscose rayon (regenerated cellulose), and wool (polyamide).
