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

History

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

The Manufacturing
Process

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

Drying

• 3 After the polyester emerges from polymerization,Intelligent Electronic Digital Display Temperature 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.Wifi Smart Switch, which are usually round,Smart Touch Wall Light Switch. The number of holes in the spinneret determines the size of the yarn,Laundry Liquid 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,Liquor 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,Oil Filling Production Line.
• Automatic Filling Production Line,Automatic Blanking Machine. Also,Spray Adhesive Type Cartoning Machine,Double-head.

Winding

• 8 After the polyester yarn is drawn, it is wound on large bobbins or flat-wound packages, ready to be woven into material.

Vertical Powder Packing Machine

Plug Type Cartoning 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,Two or Four Cups Filling and Sealing Machine. The rope-3-10L Bottle Water Filling Machine.

Drawing tow

• 1 Newly-3-10L Bottle Water Filling Machine.Quantitative Filling Machine.

Crimping

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

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Horizontal Type Liquid Filling Machin.Oil Filling Machine.

Cutting

• 4 Following heat setting,Linear Filling 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)Juice 3in1 Filling Machine.Pure Water Filling 3in1 Machine, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Washing-filling-capping 3in1 Machine.

The Future

Filling Machinery And Solution,HY-UV6810 Shift Data UV Inkjet Printer's fastest-growing fiber.High Resolustion 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,HY-UV8900 Shift Data Coding System, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Handheld And High Resolution Inkjet Printer. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.CO2 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.
