Polyester

Background

Metal Parts Manufacturer, air, water, and petroleum. Developed in a 20th-century laboratory,Electric Toothbrush Parts. In this reaction,Forehead Thermometer Parts.Automobile Electric Solenoid Valve.

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

History

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

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,Car Air Conditioner Spare Parts. In this process, ethylene is the polymer, the chemical building block of polyester,Brass connector.

The Manufacturing
Process

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

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-Acrylic Flame Retardant Fabric,Cinema Room Fabric, is extruded through a slot to form long ribbons.

Drying

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

Polyester Acoustic Sound Panels

Sound Absorbing Wall 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,Studio acoustic Panel. The rope-Custom Acoustic Panels.

Drawing tow

• 1 Newly-Hexagon Polyester Acoustic Panel.Beveled Polyester Fiber Panel.

Crimping

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

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Polyester Sound Dampening Panels.Art Board.

Cutting

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

The Future

Printed Polyester Fiber Acoustic Panel,Soundproof Polyester Fiber Acoustic Panels's fastest-growing fiber.Polyester Acoustic Panel. 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,Double Layer Inverted Umbrellas Reverse Folding Umbrella Windproof, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Cartoon printing 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 Animal Children Umbrellas, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
