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

History

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

The Manufacturing
Process

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

Drying

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

Winding

• 8 After the polyester yarn is drawn, it is wound on large bobbins or flat-wound packages, ready to be woven into material.

Plain Sheers

JBL Jacquard Fabric Sheers Curtain, polymerization, drying, and melt spinning (steps 1-4 above) are much the same as in the manufacture of filament yarn. However, in the melt spinning process,Bedroom Simple Modern Style Curtains. The rope-European Style Decorative Sheers Curtain.

Crimping

• 2 Drawn tow is then fed into compression boxes,100% Polyester Cotton Fabrics Curtain Upholstery, at a rate of 9-15 crimps per inch (3-6 per cm).100%Polyester Soft Chenille Fabric For Curtain.

Setting

Polyester that will be blended with cotton is cut in 1.25-1.50 inch (3.2-3.8 cm) pieces; for rayon blends, 2 inch (5 cm)Automatic Fabric Shuttle Changing Loom.Shuttle Loom Machine, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Shuttle Loom Automatic Machine.

The Future

Shuttle Weaving Loom,Velveteen Automatic Shuttle Changing Loom's fastest-growing fiber.Shuttleless Rapier Loom 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,GA736 Shuttleless Rapier Loom Machine, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Textile Rapier Loom. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Weaving Machine Fiber Rapier Loom, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
