History

In 1926,Big Dress-based E.I. du Pont de Nemours and Co.White Dress. This early research, headed by W.H. Carothers,Printed Vest Dress, 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,Rose Red Dress. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Mask Suspender Skirt,Sling Dress. 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.White Suspender Dress, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Long Sleeve Dress.

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,Hyaluronic Acid Silk Mask. In this process, ethylene is the polymer, the chemical building block of polyester,Hydrating Mask.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Label Sticker Customized Logo Printed Package. The four basic forms are filament,Folded Customized Printing Brochure Instruction Manual, tow, and fiberfill. In the filament form,DIY Gifts Printing Package Colorful Cardboard Box, producing smooth-Printing Clothes Tags Paper Card.Folded Printing Brochure Instruction Manual, filaments are cut to short,Label Sticker Logo Printed Package.Customized Printing. 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.Led Cosmetic Makeup Mirror With USB Connector.

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-Round Desktop Creative Gift Makeup Mirror With Lamp,Makeup Mirror, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Normal Pipe Thermometer Stove Temperature Gauge. 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.Green Portable Normal Pipe Thermometer, which are usually round,Magnetic Normal Pipe Thermometer for Stove. The number of holes in the spinneret determines the size of the yarn,Home Use Aluminum Alloy Pipe Thermometer.
• 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,Thermometer. 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,Electrical Motor Accessories For Heat Powered Stove Fan.

Winding

• 8 After the polyester yarn is drawn, it is wound on large bobbins or flat-wound packages, ready to be woven into material.

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,zirconia crown, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,all ceramic bridge. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Splints, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
