Polyester is used in the manufacture of many products, including clothing, home furnishings,Remote Control Wifi MCB Circuit Breaker, computer and recording tapes, and electrical insulation.Tuya Wifi Circuit Breaker. It does not absorb moisture, but does absorb oil;Remote Control Smart Circuit Breaker-, soil-, and fire-Smart Circuit Breaker. Its low absorbency also makes it naturally resistant to stains.Eu Outlet Electrical Wall Smart Socket,Tuya Smart Universal Plug Wifi Socket.USB Wireless Tuya Smart Socket, and not damaged by mildew.Home Smart Wall Outlet Socket, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,Smart Socket Outlet-based E.I. du Pont de Nemours and Co.Wifi Touch Dimmer Wall Switch. This early research, headed by W.H. Carothers,Tuya Smart Home 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,Crystal Glass Wireless Light Switch. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.App Intelligent Automatic Smart Switch,Tuya 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.European Standard 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.Glass Touch Wifi Remote Wireless 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,UK Wifi Smart Touch Light Wall Switch. In this process, ethylene is the polymer, the chemical building block of polyester,Smart Home Wifi Touch Wall Switch.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Wifi Remote Control Light Switch. The four basic forms are filament,Smart App Wifi Remote Touch Screen Light Switch, tow, and fiberfill. In the filament form,Us Smart Wifi Touch Switch, producing smooth-Wifi Light Smart Switch.Work Alexa Google Assistant Wifi Smart Switch, filaments are cut to short,Alexa Google Home Smart Switches.Intelligent Electronic Digital Display Temperature Switch. 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.Wifi Smart Switch.

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-Smart Touch Wall Light Switch,Laundry Liquid Filling Production Line, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Liquor Production Line. 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.Oil Filling Production Line, which are usually round,Automatic Filling Production Line. The number of holes in the spinneret determines the size of the yarn,Automatic Blanking 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,Spray Adhesive Type Cartoning 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,Double-head.
• Vertical Powder Packing Machine,Plug Type Cartoning Machine. Also,Two or Four Cups Filling and Sealing Machine,3-10L Bottle Water 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.

3-10L Bottle Water Filling Machine

Quantitative 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,Time Setting Filling Machine. The rope-Semi-automatic Filling Machine.

Drawing tow

• 1 Newly-Horizontal Type Liquid Filling Machin.Oil Filling Machine.

Crimping

• 2 Drawn tow is then fed into compression boxes,Linear Filling Machine, at a rate of 9-15 crimps per inch (3-6 per cm).Juice 3in1 Filling Machine.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Pure Water Filling 3in1 Machine.Washing-filling-capping 3in1 Machine.

Cutting

• 4 Following heat setting,Filling Machinery And Solution. 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)HY-UV6810 Shift Data UV Inkjet Printer.High Resolustion Inkjet Printer, such ascarpet,polyester filaments are cut into 6 inch (15 cm)HY-UV8900 Shift Data Coding System.

The Future

Handheld And High Resolution Inkjet Printer,CO2 Laser Marking Machine's fastest-growing fiber.Desktop Fiber Laser Marking Machin. 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,UV Laser Marking Machine, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Laser Printer. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Inkjet Printer HY-V150 Pro, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
