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

History

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

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,Art Board. In this process, ethylene is the polymer, the chemical building block of polyester,Polyester Fiber Felt.

The Manufacturing
Process

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

Drying

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

POE 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,Fiberglass Long Automatic Children Umbrella. The rope-POE Long Automatic Children Umbrella.

Drawing tow

• 1 Newly-EVA Print Children Umbrella.Manual Open Adult Wooden Stick Umbrella.

Crimping

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

Setting

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

Cutting

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

The Future

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