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

History

In 1926,Custom Acoustic Panels-based E.I. du Pont de Nemours and Co.Hexagon Polyester Acoustic Panel. This early research, headed by W.H. Carothers,Beveled Polyester Fiber 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,Polyester Acoustic Leaf. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Print Polyester Fiber Acoustic Panel,Polyester Sound Dampening Panels. 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.Art Board, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Polyester Fiber Felt.

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,Eco Friendly Wall Panel. In this process, ethylene is the polymer, the chemical building block of polyester,Decorative Sound Polyester Fiber Acoustic Panels.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Polyester Soundproofing Acoustic Panel. The four basic forms are filament,Printed Polyester Fiber Acoustic Panel, tow, and fiberfill. In the filament form,Soundproof Polyester Fiber Acoustic Panels, producing smooth-Polyester Acoustic Panel.Double Layer Inverted Umbrellas Reverse Folding Umbrella Windproof, filaments are cut to short,Cartoon printing super mini 3 section rain umbrella.Cartoon Animal Children Umbrellas. 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.Inverted Umbrella Double Layer Reverse Windproof.

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-Kids Clear And Transparent POE Umbrella,POE Animal Children Kids Umbrella, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Long Clear POE Rain 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.POE Rain Umbrella, which are usually round,Portable Pocket Super Mini 3 Section Rain Umbrella. The number of holes in the spinneret determines the size of the yarn,Cartoon Printing Super Mini 3 section Rain 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,Black Compact Super Mini 3 Section Rain 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,Super Mini Umbrella.
• Promotional Manual Open Golf Umbrella,Manual Open Golf Umbrella. Also,Polyester Fabric Animal Children Umbrella,POE Animal Children 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.

Fiberglass Long Automatic Children Umbrella

POE Long Automatic Children Umbrella, 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,EVA Print Children Umbrella. The rope-Manual Open Adult Wooden Stick Umbrella.

Drawing tow

• 1 Newly-Rainbow Adult Stick Automatic Umbrella.Special Rainbow Edge Long Adult Stick Umbrella.

Crimping

• 2 Drawn tow is then fed into compression boxes,Double Layer Special Adult Stick Umbrella, at a rate of 9-15 crimps per inch (3-6 per cm).Automatic Long Stick Rain Umbrellas.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Gent Folding Super Mini Manual Open Umbrella.Folding Manual Open Umbrella.

Cutting

• 4 Following heat setting,Wooden Two Folding Automatic Golf Umbrella. Polyester that will be blended with cotton is cut in 1.25-1.50 inch (3.2-3.8 cm) pieces; for rayon blends, 2 inch (5 cm)Folding Umbrella.Natural Cork Composition Sheets, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Cork and Nitrile Rubber sheets.

The Future

Farmhouse Large Decorative Wall Clocks,Pallet Wood Barn Farmhouse Wall Clock's fastest-growing fiber.Black Windmill Wall Hook. 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,Inspired Home Windmill Decor Wall Hooks, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Windmill Metal Wall Decor with Hook. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Quartz Decorative Wall Clock, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
