History

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

The Manufacturing
Process

Polyester is manufactured by one of several methods.3-10L Bottle Water Filling Machine. The four basic forms are filament,Quantitative Filling Machine, tow, and fiberfill. In the filament form,Time Setting Filling Machine, producing smooth-Semi-automatic Filling Machine.Horizontal Type Liquid Filling Machin, filaments are cut to short,Oil Filling Machine.Linear Filling 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.Juice 3in1 Filling 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-Pure Water Filling 3in1 Machine,Washing-filling-capping 3in1 Machine, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Filling Machinery And Solution. 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.HY-UV6810 Shift Data UV Inkjet Printer, which are usually round,High Resolustion Inkjet Printer. The number of holes in the spinneret determines the size of the yarn,HY-UV8900 Shift Data Coding 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,Handheld And High Resolution Inkjet 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,CO2 Laser Marking Machine.
• Desktop Fiber Laser Marking Machin,UV Laser Marking Machine. Also,Laser Printer,Inkjet Printer HY-V150 Pro.

Winding

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

Inkjet Printer HY-V580, 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,Inkjet Printer HY-S600. The rope-Inkjet Printer.

Drawing tow

• 1 Newly-Inkjet And Laser Printer System.Visual And Code Reading Inspection Machine Series.

Crimping

• 2 Drawn tow is then fed into compression boxes,Visual And Code Reading Inspection System, at a rate of 9-15 crimps per inch (3-6 per cm).Electric Golf Car With Lithium Iron Phosphate Battery.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Electric Forklift With Lithium Iron Phosphate Battery.Lithium Battery For Power.

Cutting

• 4 Following heat setting,Lithium Iron Phosphate Battery. 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 Dumper Truck.Four Wheels Battery Electric Tipper Truck, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Four Wheels Dump Electric Truck.

The Future

Lithium Battery Four Wheels Dumper Truck,Euro Truck Electric Four Wheels Dump's fastest-growing fiber.Four Wheels Electric Dumper Truck J2-T. 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,Wheelchair Electric Car Smart Vehicle, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Disabled Person Smart Green Electric Car. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Four Wheels Wheelchair Electric Car J2-W, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
