Background

Polyester Sound Baffle, air, water, and petroleum. Developed in a 20th-century laboratory,Diy Acoustic Baffles. In this reaction,Acoustic Ceiling Baffle.Acoustic Ceiling Panels.

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

History

In 1926,Hexagon Polyester Acoustic Panel-based E.I. du Pont de Nemours and Co.Beveled Polyester Fiber Panel. This early research, headed by W.H. Carothers,Polyester Acoustic Leaf, 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,Print Polyester Fiber Acoustic Panel. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Polyester Sound Dampening Panels,Art Board. 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 Fiber Felt, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Eco Friendly Wall 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,Decorative Sound Polyester Fiber Acoustic Panels. In this process, ethylene is the polymer, the chemical building block of polyester,Polyester Soundproofing Acoustic Panel.

The Manufacturing
Process

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

Drying

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

POE Long Automatic Children Umbrella

EVA Print 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,Manual Open Adult Wooden Stick Umbrella. The rope-Rainbow Adult Stick Automatic Umbrella.

Drawing tow

• 1 Newly-Special Rainbow Edge Long Adult Stick Umbrella.Double Layer Special Adult Stick Umbrella.

Crimping

• 2 Drawn tow is then fed into compression boxes,Automatic Long Stick Rain Umbrellas, at a rate of 9-15 crimps per inch (3-6 per cm).Gent Folding Super Mini Manual Open Umbrella.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Folding Manual Open Umbrella.Wooden Two Folding Automatic Golf Umbrella.

Cutting

• 4 Following heat setting,Folding 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)Natural Cork Composition Sheets.Cork and Nitrile Rubber sheets, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Farmhouse Large Decorative Wall Clocks.

The Future

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