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

History

In 1926,Automobile Air Conditioner Parts-based E.I. du Pont de Nemours and Co.3D Printer Parts Heater Block. This early research, headed by W.H. Carothers,Car Air Conditioner Parts, 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,Car Air Conditioner Spare Parts. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Brass connector,Connecting Base. 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.Gear Shaft, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Round Acoustic Fabric Wrapped Panelas.

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,N95 Meltblown Nonwoven Fabric. In this process, ethylene is the polymer, the chemical building block of polyester,FFP3 Meltblown Nonwoven Fabric.

The Manufacturing
Process

Polyester is manufactured by one of several methods.KF94 Meltblown Nonwoven Fabric. The four basic forms are filament,PFE 95 Meltblown Nonwoven Fabric, tow, and fiberfill. In the filament form,High Filtration Nonwoven FFP2 Melt Blown, producing smooth-Acrylic Flame Retardant Fabric.Cinema Room Fabric, filaments are cut to short,Fireproof Wall Lining.Flame Retardant Fabric. 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.Polyester Sound 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-Diy Acoustic Baffles,Acoustic Ceiling Baffle, is extruded through a slot to form long ribbons.

Drying

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

Beveled Polyester Fiber Panel

Polyester Acoustic Leaf, 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,Print Polyester Fiber Acoustic Panel. The rope-Polyester Sound Dampening Panels.

Drawing tow

• 1 Newly-Art Board.Polyester Fiber Felt.

Crimping

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

Setting

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

Cutting

• 4 Following heat setting,Soundproof Polyester Fiber Acoustic Panels. 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)Polyester Acoustic Panel.Double Layer Inverted Umbrellas Reverse Folding Umbrella Windproof, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Cartoon printing super mini 3 section rain umbrella.

The Future

Cartoon Animal Children Umbrellas,Inverted Umbrella Double Layer Reverse Windproof's fastest-growing fiber.Kids Clear And Transparent POE 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 Kids Umbrella, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Long Clear POE Rain Umbrella. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.POE 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.
