History

In 1926,QLED Outdoor TV 2000 Brightness-based E.I. du Pont de Nemours and Co.QLED Outdoor Waterproof TV 1500 brightness. This early research, headed by W.H. Carothers,Outdoor TVs Full Sun, 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,Outdoor TVs. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Skylight TPU Film PPF,Skylight Film PPF. 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.Transparent TPH PPF Car Paint Protection Film, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.PPF Carbon Fiber Paint Protection 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,TPH PPF. In this process, ethylene is the polymer, the chemical building block of polyester,Transparent TPU PPF Car Paint Protection Film.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Self-Healing TPU Polyurethane PPF Car Wrap Film. The four basic forms are filament,TPU PPF, tow, and fiberfill. In the filament form,Self Adhesive Marble Texture Laminated PVC Decorative Vinyl Film, producing smooth-Self Adhesive Wood Grain Laminated PVC Decorative Vinyl Film.Disposable Quarantine Clothing CPE Film, filaments are cut to short,Embossed CPE Film.CPE 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.Anti-Fog PET Film Sheet for Protective Mask Face Shield.

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-Super Clear Transparent PET Film Sheet,Transparent PET Film, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Matte TPU 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.Foggy Plastic TPU Film, which are usually round,Printable TPU Film. The number of holes in the spinneret determines the size of the yarn,Eco-Friendly Embossed Vinyl Film Sheet.
• 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,Embossed Matte Soft PVC 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,Embossed Color Flexible PVC Film.
• Anti-Yellow Embossed Soft Vinyl Film,Embossed PVC Film. Also,Color Transparent Soft Vinyl Film Roll,Fluorescent Color Translucent Soft 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.

Lamination Color Transparent Soft Vinyl Film

Lamination Plastic Soft PVC Sheet, 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,Waterproof Flexible Plastic PVC Film. The rope-Matte Normal Clear Translucent Soft Vinyl Film.

Drawing tow

• 1 Newly-Non-Toxic Transparent Flexible PVC Film.0.05mm Normal Clear Transparent Flexible PVC Film.

Crimping

• 2 Drawn tow is then fed into compression boxes,Normal Clear Soft PVC Film Vinyl Sheet, at a rate of 9-15 crimps per inch (3-6 per cm).Normal Clear PVC Film.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Flame Retardant Flexible Vinyl Film.Eco-Friendly Crystal Clear Soft PVC Film.

Cutting

• 4 Following heat setting,High Glossy Super Clear Transparent Soft Plastic PVC Film. 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)Antistatic Super Clear Soft PVC Film.Super Clear PVC Film, such ascarpet,polyester filaments are cut into 6 inch (15 cm)PVC Film.

The Future

DC Surge Protective Device,Solar Photovoltaic Cleaning Brush's fastest-growing fiber.Rocker Switch. 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,Pedal Switch, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Wall Switch. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Electrical Switch, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
