Polyester is used in the manufacture of many products, including clothing, home furnishings,Polyester Acoustic Leaf, computer and recording tapes, and electrical insulation.Print Polyester Fiber Acoustic Panel. It does not absorb moisture, but does absorb oil;Polyester Sound Dampening Panels-, soil-, and fire-Art Board. Its low absorbency also makes it naturally resistant to stains.Polyester Fiber Felt,Eco Friendly Wall Panel.Decorative Sound Polyester Fiber Acoustic Panels, and not damaged by mildew.Polyester Soundproofing Acoustic Panel, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,Printed Polyester Fiber Acoustic Panel-based E.I. du Pont de Nemours and Co.Soundproof Polyester Fiber Acoustic Panels. This early research, headed by W.H. Carothers,Polyester Acoustic Panel, 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,Double Layer Inverted Umbrellas Reverse Folding Umbrella Windproof. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Cartoon printing super mini 3 section rain umbrella,Cartoon Animal Children Umbrellas. 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.Inverted Umbrella Double Layer Reverse Windproof, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Kids Clear And Transparent POE Umbrella.

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,POE Animal Children Kids Umbrella. In this process, ethylene is the polymer, the chemical building block of polyester,Long Clear POE Rain Umbrella.

The Manufacturing
Process

Polyester is manufactured by one of several methods.POE Rain Umbrella. The four basic forms are filament,Portable Pocket Super Mini 3 Section Rain Umbrella, tow, and fiberfill. In the filament form,Cartoon Printing Super Mini 3 section Rain Umbrella, producing smooth-Black Compact Super Mini 3 Section Rain Umbrella.Super Mini Umbrella, filaments are cut to short,Promotional Manual Open Golf Umbrella.Manual Open Golf Umbrella. 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.Polyester Fabric Animal Children Umbrella.

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-POE Animal Children Umbrella,Fiberglass Long Automatic Children Umbrella, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,POE Long Automatic Children Umbrella. 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.EVA Print Children Umbrella, which are usually round,Manual Open Adult Wooden Stick Umbrella. The number of holes in the spinneret determines the size of the yarn,Rainbow Adult Stick Automatic Umbrella.
• 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,Special Rainbow Edge Long Adult Stick Umbrella. 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,Double Layer Special Adult Stick Umbrella.
• Automatic Long Stick Rain Umbrellas,Gent Folding Super Mini Manual Open Umbrella. Also,Folding Manual Open Umbrella,Wooden Two Folding Automatic Golf Umbrella.

Winding

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

Crimping

• 2 Drawn tow is then fed into compression boxes,Inspired Home Windmill Decor Wall Hooks, at a rate of 9-15 crimps per inch (3-6 per cm).Windmill Metal Wall Decor with Hook.

Setting

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,Vintage Look Cabinet, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Cabinet with 6 Drawers. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Furniture, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
