History

In 1926,1080P Small Size Mobile DVR-based E.I. du Pont de Nemours and Co.Set Of Shorts. This early research, headed by W.H. Carothers,Navel Skirt, 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,Big Dress. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.White Dress,Printed Vest 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.Rose Red Dress, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Mask Suspender Skirt.

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,Sling Dress. In this process, ethylene is the polymer, the chemical building block of polyester,White Suspender Dress.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Long Sleeve Dress. The four basic forms are filament,Hyaluronic Acid Silk Mask, tow, and fiberfill. In the filament form,Hydrating Mask, producing smooth-Label Sticker Customized Logo Printed Package.Folded Customized Printing Brochure Instruction Manual, filaments are cut to short,DIY Gifts Printing Package Colorful Cardboard Box.Printing Clothes Tags Paper Card. 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 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-Label Sticker Logo Printed Package,Customized Printing, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Led Cosmetic Makeup Mirror With USB Connector. 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.Round Desktop Creative Gift Makeup Mirror With Lamp, which are usually round,Makeup Mirror. The number of holes in the spinneret determines the size of the yarn,Normal Pipe Thermometer Stove Temperature Gauge.
• 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,Green Portable Normal Pipe 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,Magnetic Normal Pipe Thermometer for Stove.

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,DY104 - Four Blade Traditional Free Standing Classic Style Fin, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Traditional Free Standing Stove Fan. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.IPS emax press, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
