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

History

In 1926,Medical Masks Making Machine-based E.I. du Pont de Nemours and Co.Disposable Face Medical Masks Making Machine. This early research, headed by W.H. Carothers,Surgical Mask Machine, 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,Disposable Medical Protective Mask Machine. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Gauze Weaving Loom,Towel Weaving Loom. 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.LCD Video Wall, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Touch Screen Displays.

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,22 Inch Touch Inquiry Displays. In this process, ethylene is the polymer, the chemical building block of polyester,Touch Inquiry Displays.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Kiosk. The four basic forms are filament,Low Power Consumption Solar TV, tow, and fiberfill. In the filament form,24 Inch Paygo Solar TV, producing smooth-32 Inch Paygo Solar TV.40 Inch Paygo Solar TV, filaments are cut to short,Paygo Solar TV.24 Inch Solar Powered TV. 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.Solar Powered 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-Solar TVs,43 Inch Fitness Mirror Display, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Fitness Mirror. 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.Yacht TV, which are usually round,Marine TV For Sale. The number of holes in the spinneret determines the size of the yarn,Marine 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,19 Inch Caravan TV. 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,24 Inch Caravan TV.
• Caravan TV DVD Combo,24 Inch RV TV. Also,Caravan TVs,Sauna Room TV.

Winding

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

43 Inch Batroom TV Mirror, polymerization, drying, and melt spinning (steps 1-4 above) are much the same as in the manufacture of filament yarn. However, in the melt spinning process,Bathroom TV Tempered Glass. The rope-Bathroom TVs.

Drawing tow

• 1 Newly-Outdoor TV Enclosure 55 Inch.Outdoor TV Enclosure 65 Inch.

Crimping

• 2 Drawn tow is then fed into compression boxes,Outdoor TV Enclosure, at a rate of 9-15 crimps per inch (3-6 per cm).QLED Outdoor TV 2000 Brightness.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)QLED Outdoor Waterproof TV 1500 brightness.Outdoor TVs Full Sun.

Cutting

• 4 Following heat setting,Outdoor TVs. 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)Skylight TPU Film PPF.Skylight Film PPF, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Transparent TPH PPF Car Paint Protection Film.

The Future

PPF Carbon Fiber Paint Protection Film,TPH PPF's fastest-growing fiber.Transparent TPU PPF Car Paint Protection 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,Self-Healing TPU Polyurethane PPF Car Wrap Film, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,TPU PPF. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Self Adhesive Marble Texture Laminated PVC Decorative 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.
