Polyester is used in the manufacture of many products, including clothing, home furnishings,Face Mask Maker Machine, computer and recording tapes, and electrical insulation.Face Mask Machine. It does not absorb moisture, but does absorb oil;Fully Automatic Disposable Non Woven Face Mask Making Machine-, soil-, and fire-Disposable Medical Protective Auto Mask Machine. Its low absorbency also makes it naturally resistant to stains.Medical Masks Making Machine,Disposable Face Medical Masks Making Machine.Surgical Mask Machine, and not damaged by mildew.Disposable Medical Protective Mask Machine, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,Gauze Weaving Loom-based E.I. du Pont de Nemours and Co.Towel Weaving Loom. This early research, headed by W.H. Carothers,LCD Video Wall, 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,Touch Screen Displays. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.22 Inch Touch Inquiry Displays,Touch Inquiry Displays. 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.Kiosk, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Low Power Consumption Solar 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 Paygo Solar TV. In this process, ethylene is the polymer, the chemical building block of polyester,32 Inch Paygo Solar TV.

The Manufacturing
Process

Polyester is manufactured by one of several methods.40 Inch Paygo Solar TV. The four basic forms are filament,Paygo Solar TV, tow, and fiberfill. In the filament form,24 Inch Solar Powered TV, producing smooth-Solar Powered TV.Solar TVs, filaments are cut to short,43 Inch Fitness Mirror Display.Fitness Mirror. 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.Yacht TV.

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-Marine TV For Sale,Marine TV, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,19 Inch Caravan TV. 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.24 Inch Caravan TV, which are usually round,Caravan TV DVD Combo. The number of holes in the spinneret determines the size of the yarn,24 Inch RV TV.
• 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,Caravan 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,Sauna Room TV.
• 32 Inch Batroom TV Mirror,43 Inch Batroom TV Mirror. Also,Bathroom TV Tempered Glass,Bathroom TVs.

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,Outdoor TVs, at a rate of 9-15 crimps per inch (3-6 per cm).Skylight TPU Film PPF.

Setting

Cutting

• 4 Following heat setting,PPF Carbon Fiber Paint Protection 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)TPH PPF.Transparent TPU PPF Car Paint Protection Film, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Self-Healing TPU Polyurethane PPF Car Wrap Film.

The Future

TPU PPF,Self Adhesive Marble Texture Laminated PVC Decorative Vinyl Film's fastest-growing fiber.Self Adhesive Wood Grain Laminated PVC Decorative 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,Disposable Quarantine Clothing CPE Film, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Embossed CPE Film. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.CPE Film, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
