Polyester is used in the manufacture of many products, including clothing, home furnishings,Polyester Sound Baffle, computer and recording tapes, and electrical insulation.Diy Acoustic Baffles. It does not absorb moisture, but does absorb oil;Acoustic Ceiling Baffle-, soil-, and fire-Acoustic Ceiling Panels. Its low absorbency also makes it naturally resistant to stains.Acoustic Ceiling Board,Polyester Sound Absorbing panels.Decorative Polyester Fiber Acoustic Panels, and not damaged by mildew.DIY Acoustic Panels, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

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

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 Sound Dampening Panels. In this process, ethylene is the polymer, the chemical building block of polyester,Art Board.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Polyester Fiber Felt. The four basic forms are filament,Eco Friendly Wall Panel, tow, and fiberfill. In the filament form,Decorative Sound Polyester Fiber Acoustic Panels, producing smooth-Polyester Soundproofing Acoustic Panel.Printed Polyester Fiber Acoustic Panel, filaments are cut to short,Soundproof Polyester Fiber Acoustic Panels.Polyester Acoustic Panel. 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.Double Layer Inverted Umbrellas Reverse Folding Umbrella Windproof.

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-Cartoon printing super mini 3 section rain umbrella,Cartoon Animal Children Umbrellas, is extruded through a slot to form long ribbons.

Drying

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

Polyester Fabric Animal Children Umbrella, 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,POE Animal Children Umbrella. The rope-Fiberglass Long Automatic Children Umbrella.

Drawing tow

• 1 Newly-POE Long Automatic Children Umbrella.EVA Print Children Umbrella.

Crimping

• 2 Drawn tow is then fed into compression boxes,Manual Open Adult Wooden Stick Umbrella, at a rate of 9-15 crimps per inch (3-6 per cm).Rainbow Adult Stick Automatic Umbrella.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Special Rainbow Edge Long Adult Stick Umbrella.Double Layer Special Adult Stick Umbrella.

Cutting

• 4 Following heat setting,Automatic Long Stick Rain Umbrellas. 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)Gent Folding Super Mini Manual Open Umbrella.Folding Manual Open Umbrella, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Wooden Two Folding Automatic Golf Umbrella.

The Future

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