Polyester is used in the manufacture of many products, including clothing, home furnishings,Custom Steel Turning Parts, computer and recording tapes, and electrical insulation.Automobile Air Conditioner Parts. It does not absorb moisture, but does absorb oil;3D Printer Parts Heater Block-, soil-, and fire-Car Air Conditioner Parts. Its low absorbency also makes it naturally resistant to stains.Car Air Conditioner Spare Parts,Brass connector.Connecting Base, and not damaged by mildew.Gear Shaft, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,Round Acoustic Fabric Wrapped Panelas-based E.I. du Pont de Nemours and Co.N95 Meltblown Nonwoven Fabric. This early research, headed by W.H. Carothers,FFP3 Meltblown Nonwoven Fabric, 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,KF94 Meltblown Nonwoven Fabric. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.PFE 95 Meltblown Nonwoven Fabric,High Filtration Nonwoven FFP2 Melt Blown. 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.Acrylic Flame Retardant Fabric, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Cinema Room Fabric.

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,Fireproof Wall Lining. In this process, ethylene is the polymer, the chemical building block of polyester,Flame Retardant Fabric.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Polyester Sound Baffle. The four basic forms are filament,Diy Acoustic Baffles, tow, and fiberfill. In the filament form,Acoustic Ceiling Baffle, producing smooth-Acoustic Ceiling Panels.Acoustic Ceiling Board, filaments are cut to short,Polyester Sound Absorbing panels.Decorative Polyester Fiber Acoustic Panels. 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.DIY 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 Sound Panels,Sound Absorbing Wall Panels, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Studio acoustic Panel. 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.Custom Acoustic Panels, which are usually round,Hexagon Polyester Acoustic Panel. The number of holes in the spinneret determines the size of the yarn,Beveled Polyester Fiber Panel.
• 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,Polyester Acoustic Leaf. 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,Print Polyester Fiber Acoustic Panel.
• Polyester Sound Dampening Panels,Art Board. Also,Polyester Fiber Felt,Eco Friendly Wall Panel.

Winding

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

Decorative Sound Polyester Fiber Acoustic Panels

Polyester Soundproofing Acoustic Panel, 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,Printed Polyester Fiber Acoustic Panel. The rope-Soundproof Polyester Fiber Acoustic Panels.

Drawing tow

• 1 Newly-Polyester Acoustic Panel.Double Layer Inverted Umbrellas Reverse Folding Umbrella Windproof.

Crimping

• 2 Drawn tow is then fed into compression boxes,Cartoon printing super mini 3 section rain umbrella, at a rate of 9-15 crimps per inch (3-6 per cm).Cartoon Animal Children Umbrellas.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Inverted Umbrella Double Layer Reverse Windproof.Kids Clear And Transparent POE Umbrella.

Cutting

• 4 Following heat setting,POE Animal Children Kids 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)Long Clear POE Rain Umbrella.POE Rain Umbrella, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Portable Pocket Super Mini 3 Section Rain Umbrella.

The Future

Cartoon Printing Super Mini 3 section Rain Umbrella,Black Compact Super Mini 3 Section Rain Umbrella's fastest-growing fiber.Super Mini 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,Promotional Manual Open Golf Umbrella, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Manual Open Golf Umbrella. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Polyester Fabric Animal Children Umbrella, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
