History

In 1926,Children Small Indoor Playground-based E.I. du Pont de Nemours and Co.Children Driving School Playground. This early research, headed by W.H. Carothers,Sand Pond Indoor Playground, 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 1946,20-100 Square Meters Indoor Playground. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Large Comprehensive Indoor Playground,Big Ball Pool Indoor Playground. 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.High-rise Indoor Playground, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Theme Indoor Playground.

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,Indoor Playground. In this process, ethylene is the polymer, the chemical building block of polyester,High Temperature Flange Insulation Kits.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Flange Insulation Kit Gasket. The four basic forms are filament,Flange Bolt Insulation Kits, tow, and fiberfill. In the filament form,Flange Insulation Kit Gaskets, producing smooth-Pipe Flange Insulation Kits.Phenolic Flange Insulation Kits, filaments are cut to short,Flange Insulation Kits.Piping Flange Isolating Gaskets and Kits. 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.Flange Insulation Gasket Kits.

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-Piping Flange Isolating Gaskets and Kits,Flange Isolating Gasket Kits, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Flange Insulation Kit Gasket. 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.High Temperature Flange Insulation Kits, which are usually round,8 Flange Isolation Kit. The number of holes in the spinneret determines the size of the yarn,6 Flange Insulation Kit.
• 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,Phenolic Flange Insulation Kits. 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,Pipeline Flange Insulation Kits.
• Phenolic Flange Insulation Kits,Flange Isolating Gasket Kits. Also,Flange Insulation Gasket Sets,Type D Flange Insulation Gasket Kit.

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

Pillow Case Valentine Cushion Cover,Print Decorative Home Textile Cushion's fastest-growing fiber.Cushion Cover. 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,Luxury Embroidery Sheer Fabric For Curtain, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Livingroom Sheers Curtain Fabric. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Embroidery Luxury Sheer Fabric For Curtain, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
