Polyester is used in the manufacture of many products, including clothing, home furnishings,JBL Two Faced complete Blackout Curtain Fabric For Bedroom, computer and recording tapes, and electrical insulation.Automatic Fiber High Speed Rapier Machine. It does not absorb moisture, but does absorb oil;Automatic Fabric Shuttle Changing Loom-, soil-, and fire-Shuttle Loom Machine. Its low absorbency also makes it naturally resistant to stains.Shuttle Loom Automatic Machine,Shuttle Weaving Loom.Velveteen Automatic Shuttle Changing Loom, and not damaged by mildew.Shuttleless Rapier Loom Machine, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,GA736 Shuttleless Rapier Loom Machine-based E.I. du Pont de Nemours and Co.Textile Rapier Loom. This early research, headed by W.H. Carothers,Weaving Machine Fiber Rapier Loom, 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,Weaving Loom. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Rapier Loom In Weaving Machines,GA736 Weaving Machine. 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.Rapier Weaving Machine, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Rapier Machine.

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,Medical Mask Machine. In this process, ethylene is the polymer, the chemical building block of polyester,Fabric Mask Machine.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Nonvoven Mask Machine. The four basic forms are filament,Medical Mask Making Machine, tow, and fiberfill. In the filament form,Mask Making Machine, producing smooth-Face Mask Maker Machine.Face Mask Machine, filaments are cut to short,Fully Automatic Disposable Non Woven Face Mask Making Machine.Disposable Medical Protective Auto Mask Machine. 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.Medical Masks Making Machine.

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-Disposable Face Medical Masks Making Machine,Surgical Mask Machine, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Disposable Medical Protective Mask Machine. 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.Gauze Weaving Loom, which are usually round,Towel Weaving Loom. The number of holes in the spinneret determines the size of the yarn,LCD Video Wall.
• 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,Touch Screen Displays. 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,22 Inch Touch Inquiry Displays.
• Touch Inquiry Displays,Kiosk. Also,Low Power Consumption Solar TV,24 Inch Paygo Solar 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.

Crimping

• 2 Drawn tow is then fed into compression boxes,43 Inch Fitness Mirror Display, at a rate of 9-15 crimps per inch (3-6 per cm).Fitness Mirror.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Yacht TV.Marine TV For Sale.

Cutting

• 4 Following heat setting,Marine TV. 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)19 Inch Caravan TV.24 Inch Caravan TV, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Caravan TV DVD Combo.

The Future

24 Inch RV TV,Caravan TVs's fastest-growing fiber.Sauna Room TV. 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,32 Inch Batroom TV Mirror, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,43 Inch Batroom TV Mirror. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Bathroom TV Tempered Glass, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
