History

In 1926,Double-head-based E.I. du Pont de Nemours and Co.Vertical Powder Packing Machine. This early research, headed by W.H. Carothers,Plug Type Cartoning 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,Two or Four Cups Filling and Sealing Machine. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.3-10L Bottle Water Filling Machine,3-10L Bottle Water 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.Quantitative Filling Machine, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Time Setting Filling 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,Semi-automatic Filling Machine. In this process, ethylene is the polymer, the chemical building block of polyester,Horizontal Type Liquid Filling Machin.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Oil Filling Machine. The four basic forms are filament,Linear Filling Machine, tow, and fiberfill. In the filament form,Juice 3in1 Filling Machine, producing smooth-Pure Water Filling 3in1 Machine.Washing-filling-capping 3in1 Machine, filaments are cut to short,Filling Machinery And Solution.HY-UV6810 Shift Data UV Inkjet Printer. 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.High Resolustion Inkjet 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-HY-UV8900 Shift Data Coding System,Handheld And High Resolution Inkjet Printer, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,CO2 Laser Marking 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.Desktop Fiber Laser Marking Machin, which are usually round,UV Laser Marking Machine. The number of holes in the spinneret determines the size of the yarn,Laser Printer.
• 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,Inkjet Printer HY-V150 Pro. 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,Inkjet Printer HY-V380P.
• Inkjet Printer HY-V580,Inkjet Printer HY-S600. Also,Inkjet Printer,Inkjet And Laser Printer 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.

The Future

Four Wheels Wheelchair Electric Car J2-W,Electric 4 Wheels Cargo truck's fastest-growing fiber.Four Wheels Electric Green Logistic Car. 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,Four Wheels Electric Logistic Car J2-P, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Delivery Food Scooter Smart Truck. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.New Green Energy Car Four Wheels, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
