It does not absorb moisture, but does absorb oil;Wireless Security Automatic Door Time Lock-, soil-, and fire-Electronic Fingerprint Digital Smart Lock Door. Its low absorbency also makes it naturally resistant to stains.Wifi App Control Blue Tooth Cabinet Lock,Smart Wifi Tuya App Access.Smart Lock, and not damaged by mildew.App Tuya Wifi Smart Circuit Breaker, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,Remote Control Wifi MCB Circuit Breaker-based E.I. du Pont de Nemours and Co.Tuya Wifi Circuit Breaker. This early research, headed by W.H. Carothers,Remote Control Smart Circuit Breaker, 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,Smart Circuit Breaker. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Eu Outlet Electrical Wall Smart Socket,Tuya Smart Universal Plug Wifi Socket. 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.USB Wireless Tuya Smart Socket, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Home Smart Wall Outlet Socket.

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 Socket Outlet. In this process, ethylene is the polymer, the chemical building block of polyester,Wifi Touch Dimmer Wall Switch.

The Manufacturing
Process

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

Drying

• 3 After the polyester emerges from polymerization,Us Smart Wifi Touch 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 Light Smart Switch, which are usually round,Work Alexa Google Assistant Wifi Smart Switch. The number of holes in the spinneret determines the size of the yarn,Alexa Google Home Smart Switches.
• 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,Intelligent Electronic Digital Display Temperature Switch. 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,Wifi Smart Switch.
• Smart Touch Wall Light Switch,Laundry Liquid Filling Production Line. Also,Liquor Production Line,Oil Filling Production Line.

Winding

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

Automatic Filling Production Line

Automatic Blanking 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,Spray Adhesive Type Cartoning Machine. The rope-Double-head.

Drawing tow

• 1 Newly-Vertical Powder Packing Machine.Plug Type Cartoning Machine.

Crimping

• 2 Drawn tow is then fed into compression boxes,Two or Four Cups Filling and Sealing Machine, at a rate of 9-15 crimps per inch (3-6 per cm).3-10L Bottle Water Filling Machine.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)3-10L Bottle Water Filling Machine.Quantitative Filling Machine.

Cutting

• 4 Following heat setting,Time Setting 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)Semi-automatic Filling Machine.Horizontal Type Liquid Filling Machin, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Oil Filling Machine.

The Future

Linear Filling Machine,Juice 3in1 Filling Machine's fastest-growing fiber.Pure Water Filling 3in1 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,Washing-filling-capping 3in1 Machine, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Filling Machinery And Solution. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.HY-UV6810 Shift Data UV Inkjet Printer, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
