Polyester is used in the manufacture of many products, including clothing, home furnishings,Piping Flange Isolating Gaskets and Kits, computer and recording tapes, and electrical insulation.Flange Insulation Gasket Kits. It does not absorb moisture, but does absorb oil;Piping Flange Isolating Gaskets and Kits-, soil-, and fire-Flange Isolating Gasket Kits. Its low absorbency also makes it naturally resistant to stains.Flange Insulation Kit Gasket,High Temperature Flange Insulation Kits.8 Flange Isolation Kit, and not damaged by mildew.6 Flange Insulation Kit, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,Phenolic Flange Insulation Kits-based E.I. du Pont de Nemours and Co.Pipeline Flange Insulation Kits. This early research, headed by W.H. Carothers,Phenolic Flange Insulation 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 Gasket Sets,Type D Flange Insulation Gasket 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.Neoprene Faced Phenolic Flange Insulation Gasket Kit, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Flange Insulating Gaskets.

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,Velvet Fabric. In this process, ethylene is the polymer, the chemical building block of polyester,Leopard Snakeskin Pattern Jacquard Looped Sofa Fabric.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Luxury Snake Skin Pattern Jacquard Looped Rayon Sofa Fabric. The four basic forms are filament,780GSM High Quality Weight Tiger Stripe Jacquard Cut Velvet Fabric, tow, and fiberfill. In the filament form,Light Repellent Anti Fire Sofa Fabric, producing smooth-Sofa Fabric Home Textile Yarn Dyed Jacquard.Embroidery Fabric, filaments are cut to short,30% RAYON 70%Polyester Jacquard Trims And Tapes.JBL Jacquard Cut Velvet New Design Border Trims. 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.Jacquard Trims.

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-Jacquard Velvet Cushion Cover,New Design Gold Printed Cushion Cover Decorative Pillow, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Pillow Case Valentine Cushion Cover. 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.Print Decorative Home Textile Cushion, which are usually round,Cushion Cover. The number of holes in the spinneret determines the size of the yarn,Luxury Embroidery Sheer Fabric For Curtain.
• 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,Livingroom Sheers Curtain Fabric. 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,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

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,Textile Rapier Loom, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Weaving Machine Fiber Rapier Loom. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.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.
