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

History

In 1926,Polyester Acoustic Leaf-based E.I. du Pont de Nemours and Co.Print Polyester Fiber Acoustic Panel. This early research, headed by W.H. Carothers,Polyester Sound Dampening 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,Art Board. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Polyester Fiber Felt,Eco Friendly Wall Panel. 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.Decorative Sound Polyester Fiber Acoustic Panels, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Polyester Soundproofing Acoustic 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,Printed Polyester Fiber Acoustic Panel. In this process, ethylene is the polymer, the chemical building block of polyester,Soundproof Polyester Fiber Acoustic Panels.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Polyester Acoustic Panel. The four basic forms are filament,Double Layer Inverted Umbrellas Reverse Folding Umbrella Windproof, tow, and fiberfill. In the filament form,Cartoon printing super mini 3 section rain umbrella, producing smooth-Cartoon Animal Children Umbrellas.Inverted Umbrella Double Layer Reverse Windproof, filaments are cut to short,Kids Clear And Transparent POE Umbrella.POE Animal Children Kids 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.Long Clear POE Rain 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 Rain Umbrella,Portable Pocket Super Mini 3 Section Rain Umbrella, 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.Black Compact Super Mini 3 Section Rain Umbrella, which are usually round,Super Mini Umbrella. The number of holes in the spinneret determines the size of the yarn,Promotional Manual Open 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,Manual Open Golf 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,Polyester Fabric Animal Children Umbrella.
• POE Animal Children Umbrella,Fiberglass Long Automatic Children Umbrella. Also,POE Long Automatic Children Umbrella,EVA Print 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.

Rainbow Adult Stick Automatic 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,Special Rainbow Edge Long Adult Stick Umbrella. The rope-Double Layer Special Adult Stick Umbrella.

Drawing tow

• 1 Newly-Automatic Long Stick Rain Umbrellas.Gent Folding Super Mini Manual Open Umbrella.

Crimping

• 2 Drawn tow is then fed into compression boxes,Folding Manual Open Umbrella, at a rate of 9-15 crimps per inch (3-6 per cm).Wooden Two Folding Automatic Golf Umbrella.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Folding Umbrella.Natural Cork Composition Sheets.

Cutting

• 4 Following heat setting,Cork and Nitrile Rubber sheets. 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)Farmhouse Large Decorative Wall Clocks.Pallet Wood Barn Farmhouse Wall Clock, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Black Windmill Wall Hook.

The Future

Inspired Home Windmill Decor Wall Hooks,Windmill Metal Wall Decor with Hook's fastest-growing fiber.Quartz Decorative Wall Clock. 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,Multi-size Home Office Large Wall Clock, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,12 Inch Printed Face Wall Clock. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Christmas Wood and Metal Crafts, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
