Polyester is used in the manufacture of many products, including clothing, home furnishings,Automatic Blanking Machine, computer and recording tapes, and electrical insulation.Spray Adhesive Type Cartoning Machine. It does not absorb moisture, but does absorb oil;Double-head-, soil-, and fire-Vertical Powder Packing Machine. Its low absorbency also makes it naturally resistant to stains.Plug Type Cartoning Machine,Two or Four Cups Filling and Sealing Machine.3-10L Bottle Water Filling Machine, and not damaged by mildew.3-10L Bottle Water Filling Machine, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,Quantitative Filling Machine-based E.I. du Pont de Nemours and Co.Time Setting Filling Machine. This early research, headed by W.H. Carothers,Semi-automatic Filling 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,Horizontal Type Liquid Filling Machin. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Oil Filling Machine,Linear Filling 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.Juice 3in1 Filling Machine, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Pure Water Filling 3in1 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,Washing-filling-capping 3in1 Machine. In this process, ethylene is the polymer, the chemical building block of polyester,Filling Machinery And Solution.

The Manufacturing
Process

Polyester is manufactured by one of several methods.HY-UV6810 Shift Data UV Inkjet Printer. The four basic forms are filament,High Resolustion Inkjet Printer, tow, and fiberfill. In the filament form,HY-UV8900 Shift Data Coding System, producing smooth-Handheld And High Resolution Inkjet Printer.CO2 Laser Marking Machine, filaments are cut to short,Desktop Fiber Laser Marking Machin.UV Laser Marking 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.Laser Printer.

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-Inkjet Printer HY-V150 Pro,Inkjet Printer HY-V380P, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Inkjet Printer HY-V580. 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.Inkjet Printer HY-S600, which are usually round,Inkjet Printer. The number of holes in the spinneret determines the size of the yarn,Inkjet And Laser Printer System.
• 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,Visual And Code Reading Inspection Machine Series. 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,Visual And Code Reading Inspection System.

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,Wheelchair Electric Car Smart Vehicle, at a rate of 9-15 crimps per inch (3-6 per cm).Disabled Person Smart Green Electric Car.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Four Wheels Wheelchair Electric Car J2-W.Electric 4 Wheels Cargo truck.

Cutting

• 4 Following heat setting,Four Wheels Electric Green Logistic Car. 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)Four Wheels Electric Logistic Car J2-P.Delivery Food Scooter Smart Truck, such ascarpet,polyester filaments are cut into 6 inch (15 cm)New Green Energy Car Four Wheels.

The Future

Passager Electric Vehicle Four Wheels,Electric Car Automatic Control Family New Cars's fastest-growing fiber.Fast Food Delivery Electric Dumper Cargo Truck. 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,Three Wheels Battery Electric Tipper Truck, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Lithium Iron Phosphate Battery Three Wheels Dumper Electric Car. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.3-ply Disposable Blue BFE Face Mask, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
