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

History

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

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,Type D Flange Insulation Gasket Kit. In this process, ethylene is the polymer, the chemical building block of polyester,Neoprene Faced Phenolic Flange Insulation Gasket Kit.

The Manufacturing
Process

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

Drying

• 3 After the polyester emerges from polymerization,Jacquard 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 Velvet Cushion Cover, which are usually round,New Design Gold Printed Cushion Cover Decorative Pillow. The number of holes in the spinneret determines the size of the yarn,Pillow Case Valentine Cushion Cover.
• 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,Print Decorative Home Textile Cushion. 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,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

Shuttle Loom Machine,Shuttle Loom Automatic Machine's fastest-growing fiber.Shuttle Weaving 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,Velveteen Automatic Shuttle Changing Loom, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Shuttleless Rapier Loom Machine. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.GA736 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.
