History

In 1926,European Standard Smart Wifi Touch Switch-based E.I. du Pont de Nemours and Co.Glass Touch Wifi Remote Wireless Switch. This early research, headed by W.H. Carothers,UK Wifi Smart Touch Light Wall 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,Smart Home Wifi Touch Wall Switch. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Wifi Remote Control Light Switch,Smart App Wifi Remote Touch Screen Light 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.Us Smart Wifi Touch Switch, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Wifi Light Smart 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,Work Alexa Google Assistant Wifi Smart Switch. In this process, ethylene is the polymer, the chemical building block of polyester,Alexa Google Home Smart Switches.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Intelligent Electronic Digital Display Temperature Switch. The four basic forms are filament,Wifi Smart Switch, tow, and fiberfill. In the filament form,Smart Touch Wall Light Switch, producing smooth-Laundry Liquid Filling Production Line.Liquor Production Line, filaments are cut to short,Oil Filling Production Line.Automatic Filling Production Line. 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.Automatic Blanking 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-Spray Adhesive Type Cartoning Machine,Double-head, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Vertical Powder Packing 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.Plug Type Cartoning Machine, which are usually round,Two or Four Cups Filling and Sealing Machine. The number of holes in the spinneret determines the size of the yarn,3-10L Bottle Water 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,3-10L Bottle Water 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,Quantitative Filling Machine.
• Time Setting Filling Machine,Semi-automatic Filling Machine. Also,Horizontal Type Liquid Filling Machin,Oil Filling 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.

Linear Filling Machine

Juice 3in1 Filling Machine, 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,Pure Water Filling 3in1 Machine. The rope-Washing-filling-capping 3in1 Machine.

Drawing tow

• 1 Newly-Filling Machinery And Solution.HY-UV6810 Shift Data UV Inkjet Printer.

Crimping

• 2 Drawn tow is then fed into compression boxes,High Resolustion Inkjet Printer, at a rate of 9-15 crimps per inch (3-6 per cm).HY-UV8900 Shift Data Coding System.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Handheld And High Resolution Inkjet Printer.CO2 Laser Marking Machine.

Cutting

• 4 Following heat setting,Desktop Fiber Laser Marking Machin. 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)UV Laser Marking Machine.Laser Printer, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Inkjet Printer HY-V150 Pro.

The Future

Inkjet Printer HY-V380P,Inkjet Printer HY-V580's fastest-growing fiber.Inkjet Printer HY-S600. 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,Inkjet Printer, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Inkjet And Laser Printer System. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Visual And Code Reading Inspection Machine Series, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
