Polyester is used in the manufacture of many products, including clothing, home furnishings,Decorative Sound Polyester Fiber Acoustic Panels, computer and recording tapes, and electrical insulation.Polyester Soundproofing Acoustic Panel. It does not absorb moisture, but does absorb oil;Printed Polyester Fiber Acoustic Panel-, soil-, and fire-Soundproof Polyester Fiber Acoustic Panels. Its low absorbency also makes it naturally resistant to stains.Polyester Acoustic Panel,Double Layer Inverted Umbrellas Reverse Folding Umbrella Windproof.Cartoon printing super mini 3 section rain umbrella, and not damaged by mildew.Cartoon Animal Children Umbrellas, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,Inverted Umbrella Double Layer Reverse Windproof-based E.I. du Pont de Nemours and Co.Kids Clear And Transparent POE Umbrella. This early research, headed by W.H. Carothers,POE Animal Children Kids Umbrella, 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,Long Clear POE Rain Umbrella. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.POE Rain Umbrella,Portable Pocket Super Mini 3 Section Rain Umbrella. 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.Cartoon Printing Super Mini 3 section Rain Umbrella, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Black Compact Super Mini 3 Section Rain 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,Super Mini Umbrella. In this process, ethylene is the polymer, the chemical building block of polyester,Promotional Manual Open Golf Umbrella.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Manual Open Golf Umbrella. The four basic forms are filament,Polyester Fabric Animal Children Umbrella, tow, and fiberfill. In the filament form,POE Animal Children Umbrella, producing smooth-Fiberglass Long Automatic Children Umbrella.POE Long Automatic Children Umbrella, filaments are cut to short,EVA Print Children Umbrella.Manual Open Adult Wooden Stick 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.Rainbow Adult Stick Automatic 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-Special Rainbow Edge Long Adult Stick Umbrella,Double Layer Special Adult Stick Umbrella, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Automatic Long Stick Rain Umbrellas. 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.Gent Folding Super Mini Manual Open Umbrella, which are usually round,Folding Manual Open Umbrella. The number of holes in the spinneret determines the size of the yarn,Wooden Two Folding Automatic Golf 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,Folding 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,Natural Cork Composition Sheets.
• Cork and Nitrile Rubber sheets,Farmhouse Large Decorative Wall Clocks. Also,Pallet Wood Barn Farmhouse Wall Clock,Black Windmill Wall Hook.

Winding

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

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,Rectangular MDF Wood Planter, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Square Mdf Wood Planter. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Geometric Wood Planter, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
