Background

High Filtration Nonwoven FFP2 Melt Blown, air, water, and petroleum. Developed in a 20th-century laboratory,Acrylic Flame Retardant Fabric. In this reaction,Cinema Room Fabric.Fireproof Wall Lining.

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

History

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

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,Print Polyester Fiber Acoustic Panel. In this process, ethylene is the polymer, the chemical building block of polyester,Polyester Sound Dampening Panels.

The Manufacturing
Process

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

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-Double Layer Inverted Umbrellas Reverse Folding Umbrella Windproof,Cartoon printing super mini 3 section rain umbrella, is extruded through a slot to form long ribbons.

Drying

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

Manual Open Golf 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,Polyester Fabric Animal Children Umbrella. The rope-POE Animal Children Umbrella.

Drawing tow

• 1 Newly-Fiberglass Long Automatic Children Umbrella.POE Long Automatic Children Umbrella.

Crimping

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

Setting

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

Cutting

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

The Future

Wooden Two Folding Automatic Golf Umbrella,Folding Umbrella's fastest-growing fiber.Natural Cork Composition 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,Cork and Nitrile Rubber sheets, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Farmhouse Large Decorative Wall Clocks. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Pallet Wood Barn Farmhouse 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.
