History

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

The Manufacturing
Process

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

Drying

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

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

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