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

History

In 1926,Mouthpiece for Electronics Cigarettes-based E.I. du Pont de Nemours and Co.Electronic Cigarette Holder. This early research, headed by W.H. Carothers,Custom Steel Turning 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,Automobile Air Conditioner Parts. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.3D Printer Parts Heater Block,Car Air Conditioner Parts. 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.Car Air Conditioner Spare Parts, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Brass connector.

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,Connecting Base. In this process, ethylene is the polymer, the chemical building block of polyester,Gear Shaft.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Round Acoustic Fabric Wrapped Panelas. The four basic forms are filament,N95 Meltblown Nonwoven Fabric, tow, and fiberfill. In the filament form,FFP3 Meltblown Nonwoven Fabric, producing smooth-KF94 Meltblown Nonwoven Fabric.PFE 95 Meltblown Nonwoven Fabric, filaments are cut to short,High Filtration Nonwoven FFP2 Melt Blown.Acrylic 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.Cinema Room Fabric.

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-Fireproof Wall Lining,Flame Retardant Fabric, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Polyester Sound Baffle. 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.Diy Acoustic Baffles, which are usually round,Acoustic Ceiling Baffle. The number of holes in the spinneret determines the size of the yarn,Acoustic Ceiling 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,Acoustic Ceiling 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 Sound Absorbing panels.
• Decorative Polyester Fiber Acoustic Panels,DIY Acoustic Panels. Also,Polyester Acoustic Sound Panels,Sound Absorbing Wall 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.

Studio acoustic Panel

Custom Acoustic 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,Hexagon Polyester Acoustic Panel. The rope-Beveled Polyester Fiber Panel.

Drawing tow

• 1 Newly-Polyester Acoustic Leaf.Print Polyester Fiber Acoustic Panel.

Crimping

• 2 Drawn tow is then fed into compression boxes,Polyester Sound Dampening Panels, at a rate of 9-15 crimps per inch (3-6 per cm).Art Board.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Polyester Fiber Felt.Eco Friendly Wall Panel.

Cutting

• 4 Following heat setting,Decorative Sound 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 Soundproofing Acoustic Panel.Printed Polyester Fiber Acoustic Panel, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Soundproof Polyester Fiber Acoustic Panels.

The Future

Polyester Acoustic Panel,Double Layer Inverted Umbrellas Reverse Folding Umbrella Windproof's fastest-growing fiber.Cartoon printing 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 Animal Children Umbrellas, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Inverted Umbrella Double Layer Reverse Windproof. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Kids Clear And Transparent POE Umbrella, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
