Its low absorbency also makes it naturally resistant to stains.Smart Touch Wall Light Switch,Laundry Liquid Filling Production Line.Liquor Production Line, and not damaged by mildew.Oil Filling Production Line, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

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

The Manufacturing
Process

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

Drying

• 3 After the polyester emerges from polymerization,High Resolustion 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.HY-UV8900 Shift Data Coding System, which are usually round,Handheld And High Resolution Inkjet Printer. The number of holes in the spinneret determines the size of the yarn,CO2 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,Desktop Fiber Laser Marking Machin. 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,UV Laser Marking Machine.
• Laser Printer,Inkjet Printer HY-V150 Pro. Also,Inkjet Printer HY-V380P,Inkjet Printer HY-V580.

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

Inkjet Printer, 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 And Laser Printer System. The rope-Visual And Code Reading Inspection Machine Series.

Drawing tow

• 1 Newly-Visual And Code Reading Inspection System.Electric Golf Car With Lithium Iron Phosphate Battery.

Crimping

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

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Lithium Iron Phosphate Battery.Four Wheels Dumper Truck.

Cutting

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

The Future

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