Its low absorbency also makes it naturally resistant to stains.3-10L Bottle Water Filling Machine,3-10L Bottle Water Filling Machine.Quantitative Filling Machine, and not damaged by mildew.Time Setting Filling Machine, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,Semi-automatic Filling Machine-based E.I. du Pont de Nemours and Co.Horizontal Type Liquid Filling Machin. This early research, headed by W.H. Carothers,Oil 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,Linear Filling Machine. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Juice 3in1 Filling Machine,Pure Water Filling 3in1 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.Washing-filling-capping 3in1 Machine, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Filling Machinery And Solution.

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,HY-UV6810 Shift Data UV Inkjet Printer. In this process, ethylene is the polymer, the chemical building block of polyester,High Resolustion Inkjet Printer.

The Manufacturing
Process

Polyester is manufactured by one of several methods.HY-UV8900 Shift Data Coding System. The four basic forms are filament,Handheld And High Resolution Inkjet Printer, tow, and fiberfill. In the filament form,CO2 Laser Marking Machine, producing smooth-Desktop Fiber Laser Marking Machin.UV Laser Marking Machine, filaments are cut to short,Laser Printer.Inkjet Printer HY-V150 Pro. 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.Inkjet Printer HY-V380P.

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-Inkjet Printer HY-V580,Inkjet Printer HY-S600, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,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.Inkjet And Laser Printer System, which are usually round,Visual And Code Reading Inspection Machine Series. The number of holes in the spinneret determines the size of the yarn,Visual And Code Reading Inspection 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,Electric Golf Car With Lithium Iron Phosphate Battery. 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,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 Four Wheels Dumper Truck, 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,Euro Truck Electric Four Wheels Dump. The rope-Four Wheels Electric Dumper Truck J2-T.

Drawing tow

• 1 Newly-Wheelchair Electric Car Smart Vehicle.Disabled Person Smart Green Electric Car.

Crimping

• 2 Drawn tow is then fed into compression boxes,Four Wheels Wheelchair Electric Car J2-W, at a rate of 9-15 crimps per inch (3-6 per cm).Electric 4 Wheels Cargo truck.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Four Wheels Electric Green Logistic Car.Four Wheels Electric Logistic Car J2-P.

Cutting

• 4 Following heat setting,Delivery Food Scooter Smart 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)New Green Energy Car Four Wheels.Passager Electric Vehicle Four Wheels, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Electric Car Automatic Control Family New Cars.

The Future

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,3-ply Disposable Blue BFE Face Mask, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,FDA Approved Disposable Personal Mask. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Medical Surgical 3 Ply Face Mask, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
