Polyester is used in the manufacture of many products, including clothing, home furnishings,Touch Inquiry Displays, computer and recording tapes, and electrical insulation.Kiosk. It does not absorb moisture, but does absorb oil;Low Power Consumption Solar TV-, soil-, and fire-24 Inch Paygo Solar TV. Its low absorbency also makes it naturally resistant to stains.32 Inch Paygo Solar TV,40 Inch Paygo Solar TV.Paygo Solar TV, and not damaged by mildew.24 Inch Solar Powered TV, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

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

The Manufacturing
Process

Polyester is manufactured by one of several methods.24 Inch RV TV. The four basic forms are filament,Caravan TVs, tow, and fiberfill. In the filament form,Sauna Room TV, producing smooth-32 Inch Batroom TV Mirror.43 Inch Batroom TV Mirror, filaments are cut to short,Bathroom TV Tempered Glass.Bathroom TVs. 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 55 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 65 Inch,Outdoor TV Enclosure, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,QLED Outdoor TV 2000 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.QLED Outdoor Waterproof TV 1500 brightness, which are usually round,Outdoor TVs Full Sun. The number of holes in the spinneret determines the size of the yarn,Outdoor TVs.
• 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 TPU 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,Skylight Film PPF.
• Transparent TPH PPF Car Paint Protection Film,PPF Carbon Fiber Paint Protection Film. Also,TPH PPF,Transparent TPU PPF Car Paint Protection 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,CPE Film, at a rate of 9-15 crimps per inch (3-6 per cm).Anti-Fog PET Film Sheet for Protective Mask Face Shield.

Setting

Cutting

• 4 Following heat setting,Matte TPU Film. Polyester that will be blended with cotton is cut in 1.25-1.50 inch (3.2-3.8 cm) pieces; for rayon blends, 2 inch (5 cm)Foggy Plastic TPU Film.Printable TPU Film, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Eco-Friendly Embossed Vinyl Film Sheet.

The Future

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