Polyester is used in the manufacture of many products, including clothing, home furnishings,Transparent TPH PPF Car Paint Protection Film, computer and recording tapes, and electrical insulation.PPF Carbon Fiber Paint Protection Film. It does not absorb moisture, but does absorb oil;TPH PPF-, soil-, and fire-Transparent TPU PPF Car Paint Protection Film. Its low absorbency also makes it naturally resistant to stains.Self-Healing TPU Polyurethane PPF Car Wrap Film,TPU PPF.Self Adhesive Marble Texture Laminated PVC Decorative Vinyl Film, and not damaged by mildew.Self Adhesive Wood Grain Laminated PVC Decorative Vinyl Film, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,Disposable Quarantine Clothing CPE Film-based E.I. du Pont de Nemours and Co.Embossed CPE Film. This early research, headed by W.H. Carothers,CPE Film, 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,Anti-Fog PET Film Sheet for Protective Mask Face Shield. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Super Clear Transparent PET Film Sheet,Transparent PET Film. 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.Matte TPU Film, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Foggy Plastic TPU Film.

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,Printable TPU Film. In this process, ethylene is the polymer, the chemical building block of polyester,Eco-Friendly Embossed Vinyl Film Sheet.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Embossed Matte Soft PVC Film. The four basic forms are filament,Embossed Color Flexible PVC Film, tow, and fiberfill. In the filament form,Anti-Yellow Embossed Soft Vinyl Film, producing smooth-Embossed PVC Film.Color Transparent Soft Vinyl Film Roll, filaments are cut to short,Fluorescent Color Translucent Soft PVC Film.Lamination Color Transparent Soft Vinyl Film. 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.Lamination Plastic Soft PVC Sheet.

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-Waterproof Flexible Plastic PVC Film,Matte Normal Clear Translucent Soft Vinyl Film, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Non-Toxic Transparent Flexible PVC Film. 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.0.05mm Normal Clear Transparent Flexible PVC Film, which are usually round,Normal Clear Soft PVC Film Vinyl Sheet. The number of holes in the spinneret determines the size of the yarn,Normal Clear PVC Film.
• 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,Flame Retardant Flexible Vinyl Film. 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,Eco-Friendly Crystal Clear Soft PVC Film.
• High Glossy Super Clear Transparent Soft Plastic PVC Film,Antistatic Super Clear Soft PVC Film. Also,Super Clear PVC Film,PVC Film.

Winding

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

DC Surge Protective Device

Solar Photovoltaic Cleaning Brush, 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,Rocker Switch. The rope-Pedal Switch.

Drawing tow

• 1 Newly-Wall Switch.Electrical Switch.

Crimping

• 2 Drawn tow is then fed into compression boxes,Solar Photovoltaic DC Combiner Box, at a rate of 9-15 crimps per inch (3-6 per cm).Solar Distribution Junction Boxes.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)PV Array String DC Combiner Box.Solar Ip65 Waterproof DC Combiner Box.

Cutting

• 4 Following heat setting,DC Combiner Box. 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)Home Wifi Digital Lock.Remote Control Tuya Smart Door Lock, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Waterproof Wifi App Access Control Reader Door Lock.

The Future

Home Electronic Electric Tuya App Wifi Smart Lock,Wireless Security Automatic Door Time Lock's fastest-growing fiber.Electronic Fingerprint Digital Smart Lock Door. 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,Wifi App Control Blue Tooth Cabinet Lock, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Smart Wifi Tuya App Access. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Smart Lock, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
