It does not absorb moisture, but does absorb oil;USB Wireless Tuya Smart Socket-, soil-, and fire-Home Smart Wall Outlet Socket. Its low absorbency also makes it naturally resistant to stains.Smart Socket Outlet,Wifi Touch Dimmer Wall Switch.Tuya Smart Home Light Switch, and not damaged by mildew.Crystal Glass Wireless Light Switch, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

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

The Manufacturing
Process

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

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-Automatic Filling Production Line,Automatic Blanking Machine, is extruded through a slot to form long ribbons.

Drying

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

Horizontal Type Liquid Filling Machin

Oil 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,Linear Filling Machine. The rope-Juice 3in1 Filling Machine.

Drawing tow

• 1 Newly-Pure Water Filling 3in1 Machine.Washing-filling-capping 3in1 Machine.

Crimping

• 2 Drawn tow is then fed into compression boxes,Filling Machinery And Solution, at a rate of 9-15 crimps per inch (3-6 per cm).HY-UV6810 Shift Data UV Inkjet Printer.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)High Resolustion Inkjet Printer.HY-UV8900 Shift Data Coding System.

Cutting

• 4 Following heat setting,Handheld And High Resolution 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)CO2 Laser Marking Machine.Desktop Fiber Laser Marking Machin, such ascarpet,polyester filaments are cut into 6 inch (15 cm)UV Laser Marking Machine.

The Future

Laser Printer,Inkjet Printer HY-V150 Pro's fastest-growing fiber.Inkjet Printer HY-V380P. 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,Inkjet Printer HY-V580, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Inkjet Printer HY-S600. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.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.
