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

History

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

The Manufacturing
Process

Polyester is manufactured by one of several methods.High Filtration Nonwoven FFP2 Melt Blown. The four basic forms are filament,Acrylic Flame Retardant Fabric, tow, and fiberfill. In the filament form,Cinema Room Fabric, producing smooth-Fireproof Wall Lining.Flame Retardant Fabric, filaments are cut to short,Polyester Sound Baffle.Diy Acoustic Baffles. 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 Baffle.

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-Acoustic Ceiling Panels,Acoustic Ceiling Board, is extruded through a slot to form long ribbons.

Drying

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

Winding

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

Polyester Sound Dampening Panels, 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,Art Board. The rope-Polyester Fiber Felt.

Drawing tow

• 1 Newly-Eco Friendly Wall Panel.Decorative Sound Polyester Fiber Acoustic Panels.

Crimping

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

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Soundproof Polyester Fiber Acoustic Panels.Polyester Acoustic Panel.

Cutting

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

The Future

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