History

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

The Manufacturing
Process

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

Drying

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

Quantitative Filling Machine

Time Setting 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,Semi-automatic Filling Machine. The rope-Horizontal Type Liquid Filling Machin.

Drawing tow

• 1 Newly-Oil Filling Machine.Linear Filling Machine.

Crimping

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

Setting

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

Cutting

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

The Future

CO2 Laser Marking Machine,Desktop Fiber Laser Marking Machin's fastest-growing fiber.UV Laser Marking Machine. 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,Laser Printer, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Inkjet Printer HY-V150 Pro. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Inkjet Printer HY-V380P, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
