History

In 1926,Oil Filling Production Line-based E.I. du Pont de Nemours and Co.Automatic Filling Production Line. This early research, headed by W.H. Carothers,Automatic Blanking 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,Spray Adhesive Type Cartoning Machine. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Double-head,Vertical Powder Packing 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.Plug Type Cartoning Machine, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Two or Four Cups Filling and Sealing 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,3-10L Bottle Water Filling 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.Quantitative Filling Machine. The four basic forms are filament,Time Setting Filling Machine, tow, and fiberfill. In the filament form,Semi-automatic Filling Machine, producing smooth-Horizontal Type Liquid Filling Machin.Oil Filling Machine, filaments are cut to short,Linear Filling Machine.Juice 3in1 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.Pure Water Filling 3in1 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-Washing-filling-capping 3in1 Machine,Filling Machinery And Solution, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,HY-UV6810 Shift Data UV 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.High Resolustion Inkjet Printer, which are usually round,HY-UV8900 Shift Data Coding System. The number of holes in the spinneret determines the size of the yarn,Handheld And High Resolution Inkjet 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,CO2 Laser Marking Machine. 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,Desktop Fiber Laser Marking Machin.
• UV Laser Marking Machine,Laser Printer. Also,Inkjet Printer HY-V150 Pro,Inkjet Printer HY-V380P.

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-S600, 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. The rope-Inkjet And Laser Printer System.

Drawing tow

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

Crimping

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

Setting

Cutting

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

The Future

Euro Truck Electric Four Wheels Dump,Four Wheels Electric Dumper Truck J2-T's fastest-growing fiber.Wheelchair Electric Car Smart Vehicle. 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,Disabled Person Smart Green Electric Car, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Four Wheels Wheelchair Electric Car J2-W. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Electric 4 Wheels Cargo truck, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
