Polyester is used in the manufacture of many products, including clothing, home furnishings,Masking Tapes, computer and recording tapes, and electrical insulation.Printed Packing Tape. It does not absorb moisture, but does absorb oil;Printing Tape-, soil-, and fire-Grid Kraft Tape. Its low absorbency also makes it naturally resistant to stains.Eco-Friendly Paper Packing Tape,Self Adhesive Kraft Paper Tape.LOGO Tape, and not damaged by mildew.Sticky Lint Roller Tape, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,Handled Sticky Roller-based E.I. du Pont de Nemours and Co.Pet Stick Grip Roller Tape. This early research, headed by W.H. Carothers,Sticky Roller Mop Refill, 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,Pet Hair Sticky Remover. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.FG53 SERIES IP65 LED TRI-PROOF LAMP,FG55 SERIES IP65 LED TRI-PROOF LAMP. 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.FG06 SERIES IP65 LED WATERPROOF LAMP, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.FB01A SERIES IP54 LED WATERPROOF LAMP.

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,FG11 SERIES IP65 LED WATERPROOF LAMP. In this process, ethylene is the polymer, the chemical building block of polyester,FB02 SERIES IP20 LED WATERPROOF LAMP.

The Manufacturing
Process

Polyester is manufactured by one of several methods.FE05 SERIES IP65 LED WATERPROOF LAMP. The four basic forms are filament,FLD-A SERIES IP65 LED FLOOD LIGHT, tow, and fiberfill. In the filament form,Flood Light, producing smooth-FE03 SERIES IP65 LED DUSTPROOF LAMP.FE05 SERIES IP65 LED DUSTPROOF LAMP, filaments are cut to short,FI81E SERIES IP65 LED DUSTPROOF LAMP.FI88E SERIES IP65 LED DUSTPROOF LAMP. 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.FI89E SERIES IP65 LED DUSTPROOF LAMP.

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-FG03 SEREIS IP67 LED DUSTPROOF LAMP,FG04 SERIES IP65 LED DUSTPROOF LAMP, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,FG06 SERIES IP65 LED DUSTPROOF LAMP. 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.FB01A SERIES IP54 LED DUSTPROOF LAMP, which are usually round,FG11 SERIES IP65 LED DUSTPROOF LAMP. The number of holes in the spinneret determines the size of the yarn,FB02 SERIES IP20 LED DUSTPROOF LAMP.
• 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,Dustproof Light. 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,Fluorescent Tri-Proof Light.
• FE01 SERIES IP65 LED TRI-PROOF LAMP,FE03 SERIES IP65 LED TRI-PROOF LAMP. Also,FI81E SERIES IP65 LED TRI-PROOF LAMP,FG06 SERIES IP65 LED TRI-PROOF LAMP.

Winding

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

FI81 SERIES IP65 T8 LED TUBES FIXTURE, 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,FI82 SERIES IP65 T8 LED TUBES FIXTURE. The rope-FI88 SERIES IP65 T5 / T8 LED TUBES FIXTURE.

Drawing tow

• 1 Newly-FI89 SERIES IP65 T8 LED TUBES FIXTURE.LED Tri-Proof Light.

Crimping

• 2 Drawn tow is then fed into compression boxes,Tri-Proof Light, at a rate of 9-15 crimps per inch (3-6 per cm).Wall Mounted LED Mirror Cabinet with Two Doors.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)LED Lighted Mirror Cabinet with Single Door.Plastic Cylinder LED Mirror Light Lamp.

Cutting

• 4 Following heat setting,Stainless Square LED Mirror Light Lamp. 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)LED Mirror Light.Oval LED Dressing Mirror, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Rectangle LED Dressing Mirror With Two Frosted Light Strips.

The Future

Full Length Backlit Rectangle LED Dressing Mirror,Rectangle LED Dressing Mirror's fastest-growing fiber.Rectangle LED Makeup Mirror. 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,Round LED Makeup Mirror With Metal Frame, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Round LED Makeup Mirror. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.LED Makeup Mirror, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
