Polyester

Background

Brass nut, air, water, and petroleum. Developed in a 20th-century laboratory,Automatic Machine Parts. In this reaction,Balance Shaft for Cars.Metal Parts Manufacturer.

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

History

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

The Manufacturing
Process

Polyester is manufactured by one of several methods.Car Air Conditioner Parts. The four basic forms are filament,Car Air Conditioner Spare Parts, tow, and fiberfill. In the filament form,Brass connector, producing smooth-Connecting Base.Gear Shaft, filaments are cut to short,Round Acoustic Fabric Wrapped Panelas.N95 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.FFP3 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-KF94 Meltblown Nonwoven Fabric,PFE 95 Meltblown Nonwoven Fabric, is extruded through a slot to form long ribbons.

Drying

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

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 Absorbing panels

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

Drawing tow

• 1 Newly-Sound Absorbing Wall Panels.Studio acoustic Panel.

Crimping

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

Setting

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

Cutting

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

The Future

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