Polyester is used in the manufacture of many products, including clothing, home furnishings,Bicycle Turntable Indoor Playground Electric Equipment, computer and recording tapes, and electrical insulation.Indoor Playground Electric Equipment. It does not absorb moisture, but does absorb oil;Children Trampoline Indoor Playground-, soil-, and fire-Kids Trampoline Indoor Playground. Its low absorbency also makes it naturally resistant to stains.Adult Trampoline Indoor Playground,200-300 Square Meters Forest Theme Indoor Playground.300-500 Square Meters Forest Theme Indoor Playground, and not damaged by mildew.100-200 Square Meters Colorful Theme Indoor Playground, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,100-200 Square Meters British Theme Indoor Playground-based E.I. du Pont de Nemours and Co.100-200 Square Meters Ocean Theme Indoor Playground. This early research, headed by W.H. Carothers,100-200 Square Meters Macaron Theme Indoor Playground, the first synthetic fiber. Soon after, in the years 1939-41, British research chemists took interest in the du Pont studies and conducted their own research in the laboratories of Calico Printers Association, Ltd. This work resulted in the creation of the polyester fiber known in England as Terylene.

In 1946,300-500 Square Meters Macaron Theme Indoor Playground. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.100-200 Square Meters Space Theme Indoor Playground,200-500 Square Meters Space Theme Indoor Playground. Today, there are two primary types of polyester, PET (polyethylene terephthalate) and PCDT (poly-1, 4-cyclohexylene-dimethylene terephthalate). PET, the more popular type, is applicable to a wider variety of uses.Castle Theme Indoor Playground, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Children Small Indoor Playground.

Raw Materials

Polyester is a chemical term which can be broken intopoly,meaning many, andester,a basic organic chemical compound. The principle ingredient used in the manufacture of polyester is ethylene,Children Driving School Playground. In this process, ethylene is the polymer, the chemical building block of polyester,Sand Pond Indoor Playground.

The Manufacturing
Process

Polyester is manufactured by one of several methods.20-100 Square Meters Indoor Playground. The four basic forms are filament,Large Comprehensive Indoor Playground, tow, and fiberfill. In the filament form,Big Ball Pool Indoor Playground, producing smooth-High-rise Indoor Playground.Theme Indoor Playground, filaments are cut to short,Indoor Playground.High Temperature Flange Insulation Kits. Tow is a form in which continuous filaments are drawn loosely together. Fiberfill is the voluminous form used in the manufacture of quilts, pillows, and outerwear.Flange Insulation Kit Gasket.

Manufacturing Filament Yarn

Polymerization

• 1 To form polyester, dimethyl terephthalate is first reacted with ethylene glycol in the presence of a catalyst at a temperature of 302-410°F (150-210°C).
• 2 The resulting chemical, a monomer (single, non-repeating molecule) alcohol, is combined with terephthalic acid and raised to a temperature of 472°F (280°C). Newly-Flange Bolt Insulation Kits,Flange Insulation Kit Gaskets, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Pipe Flange Insulation Kits. The material is cut into tiny chips and completely dried to prevent irregularities in consistency.

Melt spinning

• 4 Polymer chips are melted at 500-518°F (260-270°C) to form a syrup-like solution.Phenolic Flange Insulation Kits, which are usually round,Flange Insulation Kits. The number of holes in the spinneret determines the size of the yarn,Piping Flange Isolating Gaskets and Kits.
• 5 At the spinning stage, other chemicals may be added to the solution to make the resulting material flame retardant, antistatic, or easier to dye.

Drawing the fiber

• 6 When polyester emerges from the spinneret,Flange Insulation Gasket Kits. The stretching forces the random polyester molecules to align in a parallel formation. This increases the strength, tenacity, and resilience of the fiber. This time, when the filaments dry,Piping Flange Isolating Gaskets and Kits.

Winding

• 8 After the polyester yarn is drawn, it is wound on large bobbins or flat-wound packages, ready to be woven into material.

6 Flange Insulation Kit

Phenolic Flange Insulation Kits, polymerization, drying, and melt spinning (steps 1-4 above) are much the same as in the manufacture of filament yarn. However, in the melt spinning process,Pipeline Flange Insulation Kits. The rope-Phenolic Flange Insulation Kits.

Crimping

• 2 Drawn tow is then fed into compression boxes,Type D Flange Insulation Gasket Kit, at a rate of 9-15 crimps per inch (3-6 per cm).Neoprene Faced Phenolic Flange Insulation Gasket Kit.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Flange Insulating Gaskets.Velvet Fabric.

Cutting

• 4 Following heat setting,Leopard Snakeskin Pattern Jacquard Looped Sofa Fabric.

The Future

However, polyester has suffered an "image problem" since that time, and clothes made out of polyester were often devalued and even ridiculed. Several new forms of polyester introduced in the early 1990s may help revitalize the image of polyester. A new form of polyester fiber,JBL Jacquard Cut Velvet New Design Border Trims, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Jacquard Trims. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Jacquard Velvet Cushion Cover, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
