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

History

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

The Manufacturing
Process

Polyester is manufactured by one of several methods.Cinema Room Fabric. The four basic forms are filament,Fireproof Wall Lining, tow, and fiberfill. In the filament form,Flame Retardant Fabric, producing smooth-Polyester Sound Baffle.Diy Acoustic Baffles, filaments are cut to short,Acoustic Ceiling Baffle.Acoustic Ceiling 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.Acoustic Ceiling Board.

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 Sound Absorbing panels,Decorative Polyester Fiber Acoustic Panels, is extruded through a slot to form long ribbons.

Drying

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

Winding

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

Art Board

Polyester Fiber Felt, 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,Eco Friendly Wall Panel. The rope-Decorative Sound Polyester Fiber Acoustic Panels.

Drawing tow

• 1 Newly-Polyester Soundproofing Acoustic Panel.Printed Polyester Fiber Acoustic Panel.

Crimping

• 2 Drawn tow is then fed into compression boxes,Soundproof Polyester Fiber Acoustic Panels, at a rate of 9-15 crimps per inch (3-6 per cm).Polyester Acoustic Panel.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Double Layer Inverted Umbrellas Reverse Folding Umbrella Windproof.Cartoon printing super mini 3 section rain umbrella.

Cutting

• 4 Following heat setting,Cartoon Animal Children Umbrellas. 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)Inverted Umbrella Double Layer Reverse Windproof.Kids Clear And Transparent POE Umbrella, such ascarpet,polyester filaments are cut into 6 inch (15 cm)POE Animal Children Kids Umbrella.

The Future

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