Polyester is used in the manufacture of many products, including clothing, home furnishings,High Temperature Flange Insulation Kits, computer and recording tapes, and electrical insulation.Flange Insulation Kit Gasket. It does not absorb moisture, but does absorb oil;Flange Bolt Insulation Kits-, soil-, and fire-Flange Insulation Kit Gaskets. Its low absorbency also makes it naturally resistant to stains.Pipe Flange Insulation Kits,Phenolic Flange Insulation Kits.Flange Insulation Kits, and not damaged by mildew.Piping Flange Isolating Gaskets and Kits, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,Flange Insulation Gasket Kits-based E.I. du Pont de Nemours and Co.Piping Flange Isolating Gaskets and Kits. This early research, headed by W.H. Carothers,Flange Isolating Gasket Kits, 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,Flange Insulation Kit Gasket. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.High Temperature Flange Insulation Kits,8 Flange Isolation Kit. 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.6 Flange Insulation Kit, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Phenolic Flange Insulation Kits.

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,Pipeline Flange Insulation Kits. In this process, ethylene is the polymer, the chemical building block of polyester,Phenolic Flange Insulation Kits.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Flange Isolating Gasket Kits. The four basic forms are filament,Flange Insulation Gasket Sets, tow, and fiberfill. In the filament form,Type D Flange Insulation Gasket Kit, producing smooth-Neoprene Faced Phenolic Flange Insulation Gasket Kit.Flange Insulating Gaskets, filaments are cut to short,Velvet Fabric.Leopard Snakeskin Pattern Jacquard Looped Sofa Fabric. 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.Luxury Snake Skin Pattern Jacquard Looped Rayon Sofa Fabric.

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-780GSM High Quality Weight Tiger Stripe Jacquard Cut Velvet Fabric,Light Repellent Anti Fire Sofa Fabric, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Sofa Fabric Home Textile Yarn Dyed Jacquard. 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.Embroidery Fabric, which are usually round,30% RAYON 70%Polyester Jacquard Trims And Tapes. The number of holes in the spinneret determines the size of the yarn,JBL Jacquard Cut Velvet New Design Border Trims.
• 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,Jacquard Trims. 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,Jacquard Velvet Cushion Cover.
• New Design Gold Printed Cushion Cover Decorative Pillow,Pillow Case Valentine Cushion Cover. Also,Print Decorative Home Textile Cushion,Cushion Cover.

Winding

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

The Future

Jacquard Curtain,JBL Two Faced complete Blackout Curtain Fabric For Bedroom's fastest-growing fiber.Automatic Fiber High Speed Rapier 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,Automatic Fabric Shuttle Changing Loom, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Shuttle Loom Machine. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Shuttle Loom Automatic Machine, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
