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

History

In 1926,Flange Insulation Kit Gasket-based E.I. du Pont de Nemours and Co.High Temperature Flange Insulation Kits. This early research, headed by W.H. Carothers,8 Flange Isolation Kit, 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 1946,6 Flange Insulation Kit. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Phenolic Flange Insulation Kits,Pipeline 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.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.Flange Isolating Gasket 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,Flange Insulation Gasket Sets. In this process, ethylene is the polymer, the chemical building block of polyester,Type D Flange Insulation Gasket Kit.

The Manufacturing
Process

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

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-Embroidery Fabric,30% RAYON 70%Polyester Jacquard Trims And Tapes, is extruded through a slot to form long ribbons.

Drying

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

Automatic Fabric Shuttle Changing Loom,Shuttle Loom Machine's fastest-growing fiber.Shuttle Loom Automatic 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,Shuttle Weaving Loom, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Velveteen Automatic Shuttle Changing Loom. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Shuttleless Rapier 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.
