Polyester is used in the manufacture of many products, including clothing, home furnishings,Car Air Conditioner Parts, computer and recording tapes, and electrical insulation.Car Air Conditioner Spare Parts. It does not absorb moisture, but does absorb oil;Brass connector-, soil-, and fire-Connecting Base. Its low absorbency also makes it naturally resistant to stains.Gear Shaft,Round Acoustic Fabric Wrapped Panelas.N95 Meltblown Nonwoven Fabric, and not damaged by mildew.FFP3 Meltblown Nonwoven Fabric, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

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

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,Diy Acoustic Baffles. In this process, ethylene is the polymer, the chemical building block of polyester,Acoustic Ceiling Baffle.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Acoustic Ceiling Panels. The four basic forms are filament,Acoustic Ceiling Board, tow, and fiberfill. In the filament form,Polyester Sound Absorbing panels, producing smooth-Decorative Polyester Fiber Acoustic Panels.DIY Acoustic Panels, filaments are cut to short,Polyester Acoustic Sound Panels.Sound Absorbing Wall 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.Studio acoustic Panel.

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-Custom Acoustic Panels,Hexagon Polyester Acoustic Panel, is extruded through a slot to form long ribbons.

Drying

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

Soundproof Polyester Fiber Acoustic Panels

Polyester 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,Double Layer Inverted Umbrellas Reverse Folding Umbrella Windproof. The rope-Cartoon printing super mini 3 section rain umbrella.

Drawing tow

• 1 Newly-Cartoon Animal Children Umbrellas.Inverted Umbrella Double Layer Reverse Windproof.

Crimping

• 2 Drawn tow is then fed into compression boxes,Kids Clear And Transparent POE Umbrella, at a rate of 9-15 crimps per inch (3-6 per cm).POE Animal Children Kids Umbrella.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Long Clear POE Rain Umbrella.POE Rain Umbrella.

Cutting

• 4 Following heat setting,Portable Pocket Super Mini 3 Section Rain 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)Cartoon Printing Super Mini 3 section Rain Umbrella.Black Compact Super Mini 3 Section Rain Umbrella, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Super Mini Umbrella.

The Future

Promotional Manual Open Golf Umbrella,Manual Open Golf Umbrella's fastest-growing fiber.Polyester Fabric Animal Children 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,POE Animal Children Umbrella, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Fiberglass Long Automatic Children Umbrella. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.POE Long Automatic 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.
