It does not absorb moisture, but does absorb oil;Remote Control Wifi MCB Circuit Breaker-, soil-, and fire-Tuya Wifi Circuit Breaker. Its low absorbency also makes it naturally resistant to stains.Remote Control Smart Circuit Breaker,Smart Circuit Breaker.Eu Outlet Electrical Wall Smart Socket, and not damaged by mildew.Tuya Smart Universal Plug Wifi Socket, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

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

The Manufacturing
Process

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

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-Intelligent Electronic Digital Display Temperature Switch,Wifi Smart Switch, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Smart Touch Wall Light Switch. 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.Laundry Liquid Filling Production Line, which are usually round,Liquor Production Line. The number of holes in the spinneret determines the size of the yarn,Oil Filling Production Line.
• 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,Automatic Filling Production Line. 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,Automatic Blanking Machine.
• Spray Adhesive Type Cartoning Machine,Double-head. Also,Vertical Powder Packing Machine,Plug Type Cartoning 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, 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,3-10L Bottle Water Filling Machine. The rope-Quantitative Filling Machine.

Drawing tow

• 1 Newly-Time Setting Filling Machine.Semi-automatic Filling Machine.

Crimping

• 2 Drawn tow is then fed into compression boxes,Horizontal Type Liquid Filling Machin, at a rate of 9-15 crimps per inch (3-6 per cm).Oil Filling Machine.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Linear Filling Machine.Juice 3in1 Filling Machine.

Cutting

• 4 Following heat setting,Pure Water Filling 3in1 Machine. 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)Washing-filling-capping 3in1 Machine.Filling Machinery And Solution, such ascarpet,polyester filaments are cut into 6 inch (15 cm)HY-UV6810 Shift Data UV Inkjet Printer.

The Future

High Resolustion Inkjet Printer,HY-UV8900 Shift Data Coding System's fastest-growing fiber.Handheld And High Resolution Inkjet Printer. 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,CO2 Laser Marking Machine, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Desktop Fiber Laser Marking Machin. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.UV Laser Marking Machine, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
