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

History

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

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,Polyester Acoustic Leaf. In this process, ethylene is the polymer, the chemical building block of polyester,Print Polyester Fiber Acoustic Panel.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Polyester Sound Dampening Panels. The four basic forms are filament,Art Board, tow, and fiberfill. In the filament form,Polyester Fiber Felt, producing smooth-Eco Friendly Wall Panel.Decorative Sound Polyester Fiber Acoustic Panels, filaments are cut to short,Polyester Soundproofing Acoustic Panel.Printed Polyester Fiber Acoustic Panel. 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.Soundproof Polyester Fiber Acoustic Panels.

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-Polyester Acoustic Panel,Double Layer Inverted Umbrellas Reverse Folding Umbrella Windproof, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Cartoon printing super mini 3 section 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.Cartoon Animal Children Umbrellas, which are usually round,Inverted Umbrella Double Layer Reverse Windproof. The number of holes in the spinneret determines the size of the yarn,Kids Clear And Transparent POE 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,POE Animal Children Kids 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,Long Clear POE Rain Umbrella.
• POE Rain Umbrella,Portable Pocket Super Mini 3 Section Rain Umbrella. Also,Cartoon Printing Super Mini 3 section Rain Umbrella,Black Compact Super Mini 3 Section Rain 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,POE Long Automatic Children Umbrella, at a rate of 9-15 crimps per inch (3-6 per cm).EVA Print Children Umbrella.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Manual Open Adult Wooden Stick Umbrella.Rainbow Adult Stick Automatic Umbrella.

Cutting

• 4 Following heat setting,Special Rainbow Edge Long Adult Stick 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)Double Layer Special Adult Stick Umbrella.Automatic Long Stick Rain Umbrellas, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Gent Folding Super Mini Manual Open Umbrella.

The Future

Folding Manual Open Umbrella,Wooden Two Folding Automatic Golf Umbrella's fastest-growing fiber.Folding Umbrella. 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,Natural Cork Composition Sheets, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Cork and Nitrile Rubber sheets. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Farmhouse Large Decorative Wall Clocks, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
