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

History

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

The Manufacturing
Process

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

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-Oil Filling Production Line,Automatic Filling Production Line, is extruded through a slot to form long ribbons.

Drying

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

Semi-automatic Filling Machine

Horizontal Type Liquid Filling Machin, 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,Oil Filling Machine. The rope-Linear Filling Machine.

Drawing tow

• 1 Newly-Juice 3in1 Filling Machine.Pure Water Filling 3in1 Machine.

Crimping

• 2 Drawn tow is then fed into compression boxes,Washing-filling-capping 3in1 Machine, at a rate of 9-15 crimps per inch (3-6 per cm).Filling Machinery And Solution.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)HY-UV6810 Shift Data UV Inkjet Printer.High Resolustion Inkjet Printer.

Cutting

• 4 Following heat setting,HY-UV8900 Shift Data Coding System. 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)Handheld And High Resolution Inkjet Printer.CO2 Laser Marking Machine, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Desktop Fiber Laser Marking Machin.

The Future

UV Laser Marking Machine,Laser Printer's fastest-growing fiber.Inkjet Printer HY-V150 Pro. 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 HY-V380P, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Inkjet Printer HY-V580. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Inkjet Printer HY-S600, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
