History

In 1926,Smart Home Wifi Touch Wall Switch-based E.I. du Pont de Nemours and Co.Wifi Remote Control Light Switch. This early research, headed by W.H. Carothers,Smart App Wifi Remote Touch Screen Light Switch, 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,Us Smart Wifi Touch Switch. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Wifi Light Smart Switch,Work Alexa Google Assistant Wifi Smart Switch. 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.Alexa Google Home Smart Switches, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Intelligent Electronic Digital Display Temperature Switch.

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,Wifi Smart Switch. In this process, ethylene is the polymer, the chemical building block of polyester,Smart Touch Wall Light Switch.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Laundry Liquid Filling Production Line. The four basic forms are filament,Liquor Production Line, tow, and fiberfill. In the filament form,Oil Filling Production Line, producing smooth-Automatic Filling Production Line.Automatic Blanking Machine, filaments are cut to short,Spray Adhesive Type Cartoning Machine.Double-head. 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.Vertical Powder Packing 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-Plug Type Cartoning Machine,Two or Four Cups Filling and Sealing Machine, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,3-10L Bottle Water Filling 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.3-10L Bottle Water Filling Machine, which are usually round,Quantitative Filling Machine. The number of holes in the spinneret determines the size of the yarn,Time Setting Filling 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,Semi-automatic Filling 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,Horizontal Type Liquid Filling Machin.
• Oil Filling Machine,Linear Filling Machine. Also,Juice 3in1 Filling Machine,Pure Water Filling 3in1 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.

Filling Machinery And Solution, 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,HY-UV6810 Shift Data UV Inkjet Printer. The rope-High Resolustion Inkjet Printer.

Drawing tow

• 1 Newly-HY-UV8900 Shift Data Coding System.Handheld And High Resolution Inkjet Printer.

Crimping

• 2 Drawn tow is then fed into compression boxes,CO2 Laser Marking Machine, at a rate of 9-15 crimps per inch (3-6 per cm).Desktop Fiber Laser Marking Machin.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)UV Laser Marking Machine.Laser Printer.

Cutting

• 4 Following heat setting,Inkjet Printer HY-V150 Pro. 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)Inkjet Printer HY-V380P.Inkjet Printer HY-V580, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Inkjet Printer HY-S600.

The Future

Inkjet Printer,Inkjet And Laser Printer System's fastest-growing fiber.Visual And Code Reading Inspection Machine Series. 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,Visual And Code Reading Inspection System, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Electric Golf Car With Lithium Iron Phosphate Battery. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Electric Forklift With Lithium Iron Phosphate Battery, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
