Polyester is used in the manufacture of many products, including clothing, home furnishings,Metal Parts Manufacturer, computer and recording tapes, and electrical insulation.Electric Toothbrush Parts. It does not absorb moisture, but does absorb oil;Forehead Thermometer Parts-, soil-, and fire-Automobile Electric Solenoid Valve. Its low absorbency also makes it naturally resistant to stains.Face Mask Machine Parts,Massage Chair Parts.Massage Push Rod of Chair, and not damaged by mildew.Small radar cover, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,Twist Pin-based E.I. du Pont de Nemours and Co.Electronic Cigarette Retainer Ring. This early research, headed by W.H. Carothers,Cutter Shaft of Mower, 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,Electronic Cigarette Base. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Electronic Cigarette Retainer Ring Neck,Auto Engine 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.Mouthpiece for Electronics Cigarettes, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Electronic Cigarette Holder.

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,Custom Steel Turning Parts. In this process, ethylene is the polymer, the chemical building block of polyester,Automobile Air Conditioner Parts.

The Manufacturing
Process

Polyester is manufactured by one of several methods.3D Printer Parts Heater Block. The four basic forms are filament,Car Air Conditioner Parts, tow, and fiberfill. In the filament form,Car Air Conditioner Spare Parts, producing smooth-Brass connector.Connecting Base, filaments are cut to short,Gear Shaft.Round Acoustic Fabric Wrapped Panelas. 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.N95 Meltblown Nonwoven 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-FFP3 Meltblown Nonwoven Fabric,KF94 Meltblown Nonwoven Fabric, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,PFE 95 Meltblown Nonwoven Fabric. 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.High Filtration Nonwoven FFP2 Melt Blown, which are usually round,Acrylic Flame Retardant Fabric. The number of holes in the spinneret determines the size of the yarn,Cinema Room Fabric.
• 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,Fireproof Wall Lining. 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,Flame Retardant Fabric.
• Polyester Sound Baffle,Diy Acoustic Baffles. Also,Acoustic Ceiling Baffle,Acoustic Ceiling 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.

Acoustic Ceiling Board

Polyester Sound Absorbing 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,Decorative Polyester Fiber Acoustic Panels. The rope-DIY Acoustic Panels.

Drawing tow

• 1 Newly-Polyester Acoustic Sound Panels.Sound Absorbing Wall Panels.

Crimping

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

Setting

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

Cutting

• 4 Following heat setting,Polyester Acoustic Leaf. 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)Print Polyester Fiber Acoustic Panel.Polyester Sound Dampening Panels, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Art Board.

The Future

Polyester Fiber Felt,Eco Friendly Wall Panel's fastest-growing fiber.Decorative Sound Polyester Fiber Acoustic Panels. 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,Polyester Soundproofing Acoustic Panel, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Printed Polyester Fiber Acoustic Panel. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Soundproof Polyester Fiber Acoustic Panels, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
