Polyester



Background

Horse Rubber Bell Boots, air, water, and petroleum. Developed in a 20th-century laboratory,Horse Rubber Parts. In this reaction,Custom Rubber Gaskets.Rubber Dust Cover.

Polyester is used in the manufacture of many products, including clothing, home furnishings,Gear Shift Lever Boot, computer and recording tapes, and electrical insulation.Auto Rubber Engine Mounting. It does not absorb moisture, but does absorb oil;Automotive Engine Rubber Mounting-, soil-, and fire-Automotive Rubber Bushings. Its low absorbency also makes it naturally resistant to stains.Stabilizer Rubber Bushing,Rubber To Metal Bonding Bushings.Rubber Bushing, and not damaged by mildew.Automotive Rubber Parts, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,Silicone Rubber Rollers-based E.I. du Pont de Nemours and Co.Rubber Coated Rollers. This early research, headed by W.H. Carothers,Non-Slip Rubber Feet, 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,Anti Abrasion Rubber Bumpers. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Rubber Bumpers,Square Rubber Grommets. 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.Custom Molded Rubber Parts, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Compression Molding Custom Rubber 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,Extrusion Molding Custom Rubber Parts. In this process, ethylene is the polymer, the chemical building block of polyester,Custom Neoprene Rubber Products.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Custom Rubber Parts Anti-Slip Handle Grip. The four basic forms are filament,EPDM Rubber Sheets, tow, and fiberfill. In the filament form,Rubber Parts, producing smooth-Custom Rubber Parts.Color Plexiglass Sheet For Making Furnitures, filaments are cut to short,Transparent Plexiglass Sheet For LED Display.Plexiglass Sheet. 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.Pure Raw Materials Color Extruded Acrylic Sheet.

The Future

Lead Free PVC Foam Sheet,White PVC Foam Sheet's fastest-growing fiber.PVC Free Foam Sheet. 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,Colors PVC Foam Board, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Low Density PVC Free Foam Board. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.PVC Foam Sheet, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.

needs more diagrams of the process in which polyester is made
i thought it was awesome, gave me a lot of info for my science fair project
This is a very usefull page but do you now what is the energy input for making polyester?

Spinning of Polyester Filament Yarn

The polyester polymer produced from PTA and MEG is extruded in the form of a ribbon. This ribbon is then converted into chips.
These chips received in the bulk packing of 750 kgs to 1250 kgs

The wet chips are dried with hot dehumidified air in the continuous dryer and fed through a hopper to the extruder for melting at high temp 285 C.Mid Speed Granulator. In the form of continuous filaments

Each spinnerette contains 12 to 196 holes. A cool controlled air is blowing across the bunch of filaments for proper cooling.Middle Speed Plastic Granulator.Low Speed Granulators.
.
the yarn produced is deoffed from the winders checked for the properties and packed in the pallets of 60 spools each.

to ajay:
Color Dose Mixer,Central Chiller - Dual Machine
Central Chiller -Single,it is mainly for sticking filaments together

Are either of the compounds cobalt dichloride or thiuram mix used in the manufacture of polyester or in the material itself. Have an allergy to these 2 compounds and am trying to trace what is causing my itch.

With being chemically sensitive, I now know why I can not wear polyester clothes or have it in sheets. The itch and rash is horrible.
