History

In 1926,Multy Side View Mobile Camera-based E.I. du Pont de Nemours and Co.Mobile PTZ Camera. This early research, headed by W.H. Carothers,1080P SD Card Mobile DVR, 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 1946,1080P Small Size Mobile DVR. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Set Of Shorts,Navel Skirt. 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.Big Dress, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.White 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,Printed Vest Dress. In this process, ethylene is the polymer, the chemical building block of polyester,Rose Red Dress.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Mask Suspender Skirt. The four basic forms are filament,Sling Dress, tow, and fiberfill. In the filament form,White Suspender Dress, producing smooth-Long Sleeve Dress.Hyaluronic Acid Silk Mask, filaments are cut to short,Hydrating Mask.Label Sticker Customized Logo Printed Package. 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.Folded Customized Printing Brochure Instruction Manual.

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-DIY Gifts Printing Package Colorful Cardboard Box,Printing Clothes Tags Paper Card, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Folded Printing Brochure Instruction Manual. 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.Label Sticker Logo Printed Package, which are usually round,Customized Printing. The number of holes in the spinneret determines the size of the yarn,Led Cosmetic Makeup Mirror With USB Connector.
• 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,Round Desktop Creative Gift Makeup Mirror With Lamp. 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,Makeup Mirror.

Winding

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

The Future

DY302 - Two Blade Traditional Free Standing Butterfly Style Fin,DY205X - Reinforced Five Blade Traditional Free Standing Flower Style Fin's fastest-growing fiber.DY204X - Reinforced Four Blade Traditional Free Standing Flower Style Fin. 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,DY204 - Four Blade Traditional Free Standing Flower Style Fin, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,DY202 - Two Blade Traditional Free Standing Flower Style Fin. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.DY104X - Reinforced Four Blade Traditional Free Standing Classic Style Fin, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
