Polyester is used in the manufacture of many products, including clothing, home furnishings,Flange Insulation Kit Gasket, computer and recording tapes, and electrical insulation.Flange Bolt Insulation Kits. It does not absorb moisture, but does absorb oil;Flange Insulation Kit Gaskets-, soil-, and fire-Pipe Flange Insulation Kits. Its low absorbency also makes it naturally resistant to stains.Phenolic Flange Insulation Kits,Flange Insulation Kits.Piping Flange Isolating Gaskets and Kits, and not damaged by mildew.Flange Insulation Gasket 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 Isolating Gasket Kits. This early research, headed by W.H. Carothers,Flange Insulation Kit Gasket, 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,High Temperature Flange Insulation Kits. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.8 Flange Isolation Kit,6 Flange Insulation 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.Phenolic Flange Insulation Kits, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Pipeline 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,Phenolic Flange Insulation Kits. In this process, ethylene is the polymer, the chemical building block of polyester,Flange Isolating Gasket Kits.

The Manufacturing
Process

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

Drying

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

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

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