History

In 1926,Double Layer Inverted Umbrellas Reverse Folding Umbrella Windproof-based E.I. du Pont de Nemours and Co.Cartoon printing super mini 3 section rain umbrella. This early research, headed by W.H. Carothers,Cartoon Animal Children Umbrellas, 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,Inverted Umbrella Double Layer Reverse Windproof. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Kids Clear And Transparent POE Umbrella,POE Animal Children Kids Umbrella. 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.Long Clear POE Rain Umbrella, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.POE Rain Umbrella.

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,Portable Pocket Super Mini 3 Section Rain Umbrella. In this process, ethylene is the polymer, the chemical building block of polyester,Cartoon Printing Super Mini 3 section Rain Umbrella.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Black Compact Super Mini 3 Section Rain Umbrella. The four basic forms are filament,Super Mini Umbrella, tow, and fiberfill. In the filament form,Promotional Manual Open Golf Umbrella, producing smooth-Manual Open Golf Umbrella.Polyester Fabric Animal Children Umbrella, filaments are cut to short,POE Animal Children Umbrella.Fiberglass Long Automatic Children Umbrella. 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.POE Long Automatic Children Umbrella.

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-EVA Print Children Umbrella,Manual Open Adult Wooden Stick Umbrella, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Rainbow Adult Stick Automatic Umbrella. 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.Special Rainbow Edge Long Adult Stick Umbrella, which are usually round,Double Layer Special Adult Stick Umbrella. The number of holes in the spinneret determines the size of the yarn,Automatic Long Stick Rain Umbrellas.
• 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,Gent Folding Super Mini Manual Open Umbrella. 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,Folding Manual Open Umbrella.
• Wooden Two Folding Automatic Golf Umbrella,Folding Umbrella. Also,Natural Cork Composition Sheets,Cork and Nitrile Rubber sheets.

Winding

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

Crimping

• 2 Drawn tow is then fed into compression boxes,Multi-size Home Office Large Wall Clock, at a rate of 9-15 crimps per inch (3-6 per cm).12 Inch Printed Face Wall Clock.

Setting

The Future

Vintage Look Cabinet,Cabinet with 6 Drawers's fastest-growing fiber.Furniture. 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,Metal Planter Tray With Handles, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Antique Metal Planter Pot with Stands Décor. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Metal Planter, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
