History

In 1926,Studio acoustic Panel-based E.I. du Pont de Nemours and Co.Custom Acoustic Panels. This early research, headed by W.H. Carothers,Hexagon Polyester Acoustic Panel, 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,Beveled Polyester Fiber Panel. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Polyester Acoustic Leaf,Print Polyester Fiber Acoustic Panel. 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.Polyester Sound Dampening Panels, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Art Board.

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,Polyester Fiber Felt. In this process, ethylene is the polymer, the chemical building block of polyester,Eco Friendly Wall Panel.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Decorative Sound Polyester Fiber Acoustic Panels. The four basic forms are filament,Polyester Soundproofing Acoustic Panel, tow, and fiberfill. In the filament form,Printed Polyester Fiber Acoustic Panel, producing smooth-Soundproof Polyester Fiber Acoustic Panels.Polyester Acoustic Panel, filaments are cut to short,Double Layer Inverted Umbrellas Reverse Folding Umbrella Windproof.Cartoon printing super mini 3 section rain 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.Cartoon Animal Children Umbrellas.

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-Inverted Umbrella Double Layer Reverse Windproof,Kids Clear And Transparent POE Umbrella, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,POE Animal Children Kids 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.Long Clear POE Rain Umbrella, which are usually round,POE Rain Umbrella. The number of holes in the spinneret determines the size of the yarn,Portable Pocket Super Mini 3 Section Rain Umbrella.
• 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,Cartoon Printing Super Mini 3 section Rain 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,Black Compact Super Mini 3 Section Rain Umbrella.
• Super Mini Umbrella,Promotional Manual Open Golf Umbrella. Also,Manual Open Golf Umbrella,Polyester Fabric Animal Children Umbrella.

Winding

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

Drawing tow

• 1 Newly-Manual Open Adult Wooden Stick Umbrella.Rainbow Adult Stick Automatic Umbrella.

Crimping

• 2 Drawn tow is then fed into compression boxes,Special Rainbow Edge Long Adult Stick Umbrella, at a rate of 9-15 crimps per inch (3-6 per cm).Double Layer Special Adult Stick Umbrella.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Automatic Long Stick Rain Umbrellas.Gent Folding Super Mini Manual Open Umbrella.

Cutting

• 4 Following heat setting,Folding Manual Open Umbrella. 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)Wooden Two Folding Automatic Golf Umbrella.Folding Umbrella, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Natural Cork Composition Sheets.

The Future

Cork and Nitrile Rubber sheets,Farmhouse Large Decorative Wall Clocks's fastest-growing fiber.Pallet Wood Barn Farmhouse Wall Clock. 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,Black Windmill Wall Hook, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Inspired Home Windmill Decor Wall Hooks. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Windmill Metal Wall Decor with Hook, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
