History

In 1926,Smart Touch Wall Light Switch-based E.I. du Pont de Nemours and Co.Laundry Liquid Filling Production Line. This early research, headed by W.H. Carothers,Liquor 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,Oil Filling Production Line. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Automatic Filling Production Line,Automatic Blanking 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.Spray Adhesive Type Cartoning Machine, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Double-head.

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,Vertical Powder Packing Machine. In this process, ethylene is the polymer, the chemical building block of polyester,Plug Type Cartoning Machine.

The Manufacturing
Process

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

Drying

• 3 After the polyester emerges from polymerization,Pure Water Filling 3in1 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.Washing-filling-capping 3in1 Machine, which are usually round,Filling Machinery And Solution. The number of holes in the spinneret determines the size of the yarn,HY-UV6810 Shift Data UV 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,High Resolustion 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,HY-UV8900 Shift Data Coding System.
• Handheld And High Resolution Inkjet Printer,CO2 Laser Marking Machine. Also,Desktop Fiber Laser Marking Machin,UV Laser Marking Machine.

Winding

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

Laser Printer

Inkjet Printer HY-V150 Pro, 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-V380P. The rope-Inkjet Printer HY-V580.

Drawing tow

• 1 Newly-Inkjet Printer HY-S600.Inkjet Printer.

Crimping

• 2 Drawn tow is then fed into compression boxes,Inkjet And Laser Printer System, at a rate of 9-15 crimps per inch (3-6 per cm).Visual And Code Reading Inspection Machine Series.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Visual And Code Reading Inspection System.Electric Golf Car With Lithium Iron Phosphate Battery.

Cutting

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

The Future

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