Polyester



Background

Camera Cleaning Cloth, air, water, and petroleum. Developed in a 20th-century laboratory,Cleaning Cloth For Eyeglasses. In this reaction,Packaging For Sunglasses.Spectacle Frame Box.

Polyester is used in the manufacture of many products, including clothing, home furnishings,Black Sunglasses Case Packaging, computer and recording tapes, and electrical insulation.Sunglasses Product Packaging. It does not absorb moisture, but does absorb oil;Paper Packaging Box For Eyeglasses Frames-, soil-, and fire-Corrugated PVC Suction Hose. Its low absorbency also makes it naturally resistant to stains.Clear And Transparent PVC Tubing,PVC Clear Hose.General Purpose PVC Garden Hose, and not damaged by mildew.Non-kink PVC Garden Hose, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,Home PVC Garden Hose-based E.I. du Pont de Nemours and Co.Flexible PVC Garden Hose. This early research, headed by W.H. Carothers,Anti-UV PVC Garden Hose, 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,PVC Garden Hose. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Torsion Free Garden Hose,Reinforced Braided PVC Hose. 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.Clear PVC Braided Hose, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Steel Wire Reinforced PVC Hose.

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,Non Toxic PVC Steel Wire Hose. In this process, ethylene is the polymer, the chemical building block of polyester,Medium Duty PVC Lay Flat Hose.

Polyester

The Manufacturing
Process

Polyester is manufactured by one of several methods.Pool Backwash PVC Layflat Hose. The four basic forms are filament,PVC Lay Flat Hose, tow, and fiberfill. In the filament form,Industrial PVC Steel Wire Suction Hose, producing smooth-Gas Hose.Oxygen and Acetylene Torch Welding Hose, filaments are cut to short,Oxygen Acetylene Hose.Vinyl Tubing. 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.Welding Gas Hose.

The Future

Clear Orange Braid PVC Water Suction Discharge Transfer Hose,Heavy Duty Fabric Reinforced PVC Suction and Discharge Hose's fastest-growing fiber.PVC Suction Hose. 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,General Purpose PVC Garden Hose, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Reinforced Braided PVC Hose. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.PVC Thunder Hose Pipe, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.

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.Non Toxic PVC Steel Wire Hose. 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.FDA Approved Food Grade PVC Steel Wire Hose.Clear PVC Fiber Reinforced Hose.
.
the yarn produced is deoffed from the winders checked for the properties and packed in the pallets of 60 spools each.

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.
