History

In 1926,Solar TVs-based E.I. du Pont de Nemours and Co.43 Inch Fitness Mirror Display. This early research, headed by W.H. Carothers,Fitness Mirror, 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,Yacht TV. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Marine TV For Sale,Marine TV. 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.19 Inch Caravan TV, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.24 Inch Caravan TV.

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,Caravan TV DVD Combo. In this process, ethylene is the polymer, the chemical building block of polyester,24 Inch RV TV.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Caravan TVs. The four basic forms are filament,Sauna Room TV, tow, and fiberfill. In the filament form,32 Inch Batroom TV Mirror, producing smooth-43 Inch Batroom TV Mirror.Bathroom TV Tempered Glass, filaments are cut to short,Bathroom TVs.Outdoor TV Enclosure 55 Inch. 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.Outdoor TV Enclosure 65 Inch.

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-Outdoor TV Enclosure,QLED Outdoor TV 2000 Brightness, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,QLED Outdoor Waterproof TV 1500 brightness. 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.Outdoor TVs Full Sun, which are usually round,Outdoor TVs. The number of holes in the spinneret determines the size of the yarn,Skylight TPU Film PPF.
• 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,Skylight Film PPF. 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,Transparent TPH PPF Car Paint Protection Film.
• PPF Carbon Fiber Paint Protection Film,TPH PPF. Also,Transparent TPU PPF Car Paint Protection Film,Self-Healing TPU Polyurethane PPF Car Wrap Film.

Winding

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

Crimping

• 2 Drawn tow is then fed into compression boxes,Anti-Fog PET Film Sheet for Protective Mask Face Shield, at a rate of 9-15 crimps per inch (3-6 per cm).Super Clear Transparent PET Film Sheet.

The Future

Embossed Color Flexible PVC Film,Anti-Yellow Embossed Soft Vinyl Film's fastest-growing fiber.Embossed PVC Film. 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,Color Transparent Soft Vinyl Film Roll, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Fluorescent Color Translucent Soft PVC Film. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Lamination Color Transparent Soft Vinyl Film, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
