History

In 1926,3-10L Bottle Water Filling Machine-based E.I. du Pont de Nemours and Co.3-10L Bottle Water Filling Machine. This early research, headed by W.H. Carothers,Quantitative 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,Time Setting Filling Machine. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Semi-automatic Filling Machine,Horizontal Type Liquid Filling Machin. 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.Oil Filling Machine, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Linear 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,Juice 3in1 Filling Machine. In this process, ethylene is the polymer, the chemical building block of polyester,Pure Water Filling 3in1 Machine.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Washing-filling-capping 3in1 Machine. The four basic forms are filament,Filling Machinery And Solution, tow, and fiberfill. In the filament form,HY-UV6810 Shift Data UV Inkjet Printer, producing smooth-High Resolustion Inkjet Printer.HY-UV8900 Shift Data Coding System, filaments are cut to short,Handheld And High Resolution Inkjet Printer.CO2 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.Desktop Fiber Laser Marking Machin.

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-UV Laser Marking Machine,Laser Printer, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Inkjet Printer HY-V150 Pro. 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-V380P, which are usually round,Inkjet Printer HY-V580. The number of holes in the spinneret determines the size of the yarn,Inkjet Printer HY-S600.
• 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. 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 And Laser Printer System.
• Visual And Code Reading Inspection Machine Series,Visual And Code Reading Inspection System. Also,Electric Golf Car With Lithium Iron Phosphate Battery,Electric Forklift With Lithium Iron Phosphate Battery.

Winding

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

Lithium Battery For Power

Lithium Iron Phosphate Battery, 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,Four Wheels Dumper Truck. The rope-Four Wheels Battery Electric Tipper Truck.

Drawing tow

• 1 Newly-Four Wheels Dump Electric Truck.Lithium Battery Four Wheels Dumper Truck.

Crimping

• 2 Drawn tow is then fed into compression boxes,Euro Truck Electric Four Wheels Dump, at a rate of 9-15 crimps per inch (3-6 per cm).Four Wheels Electric Dumper Truck J2-T.

Setting

Cutting

• 4 Following heat setting,Four Wheels Wheelchair Electric Car J2-W. 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)Electric 4 Wheels Cargo truck.Four Wheels Electric Green Logistic Car, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Four Wheels Electric Logistic Car J2-P.

The Future

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