History

In 1926,24 Inch Solar Powered TV-based E.I. du Pont de Nemours and Co.Solar Powered TV. This early research, headed by W.H. Carothers,Solar TVs, 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 1946,43 Inch Fitness Mirror Display. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Fitness Mirror,Yacht 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.Marine TV For Sale, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Marine 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,19 Inch Caravan TV. In this process, ethylene is the polymer, the chemical building block of polyester,24 Inch Caravan TV.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Caravan TV DVD Combo. The four basic forms are filament,24 Inch RV TV, tow, and fiberfill. In the filament form,Caravan TVs, producing smooth-Sauna Room TV.32 Inch Batroom TV Mirror, filaments are cut to short,43 Inch Batroom TV Mirror.Bathroom TV Tempered Glass. 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.Bathroom TVs.

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 55 Inch,Outdoor TV Enclosure 65 Inch, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Outdoor TV Enclosure. 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.QLED Outdoor TV 2000 Brightness, which are usually round,QLED Outdoor Waterproof TV 1500 brightness. The number of holes in the spinneret determines the size of the yarn,Outdoor TVs Full Sun.
• 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,Outdoor TVs. 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,Skylight TPU Film PPF.
• Skylight Film PPF,Transparent TPH PPF Car Paint Protection Film. Also,PPF Carbon Fiber Paint Protection Film,TPH PPF.

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,Embossed CPE Film, at a rate of 9-15 crimps per inch (3-6 per cm).CPE Film.

Setting

The Future

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