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

History

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

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

The Manufacturing
Process

Polyester is manufactured by one of several methods.Phenolic Flange Insulation Kits. The four basic forms are filament,Flange Isolating Gasket Kits, tow, and fiberfill. In the filament form,Flange Insulation Gasket Sets, producing smooth-Type D Flange Insulation Gasket Kit.Neoprene Faced Phenolic Flange Insulation Gasket Kit, filaments are cut to short,Flange Insulating Gaskets.Velvet 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.Leopard Snakeskin Pattern Jacquard Looped 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-Luxury Snake Skin Pattern Jacquard Looped Rayon Sofa Fabric,780GSM High Quality Weight Tiger Stripe Jacquard Cut Velvet Fabric, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Light Repellent Anti Fire Sofa Fabric. 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.Sofa Fabric Home Textile Yarn Dyed Jacquard, which are usually round,Embroidery Fabric. The number of holes in the spinneret determines the size of the yarn,30% RAYON 70%Polyester Jacquard Trims And Tapes.
• 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,JBL Jacquard Cut Velvet New Design Border 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 Trims.

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

100%Polyester Soft Chenille Fabric For Curtain,Jacquard Curtain's fastest-growing fiber.JBL Two Faced complete Blackout Curtain Fabric For Bedroom. 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 Fiber High Speed Rapier Machine, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Automatic Fabric Shuttle Changing Loom. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Shuttle Loom Machine, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
