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

History

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

The Manufacturing
Process

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

Drying

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

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

Drawing tow

• 1 Newly-Semi-automatic Filling Machine.Horizontal Type Liquid Filling Machin.

Crimping

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

Setting

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

Cutting

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

The Future

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