Polyester is used in the manufacture of many products, including clothing, home furnishings,Car Air Conditioner Spare Parts, computer and recording tapes, and electrical insulation.Brass connector. It does not absorb moisture, but does absorb oil;Connecting Base-, soil-, and fire-Gear Shaft. Its low absorbency also makes it naturally resistant to stains.Round Acoustic Fabric Wrapped Panelas,N95 Meltblown Nonwoven Fabric.FFP3 Meltblown Nonwoven Fabric, and not damaged by mildew.KF94 Meltblown Nonwoven Fabric, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,PFE 95 Meltblown Nonwoven Fabric-based E.I. du Pont de Nemours and Co.High Filtration Nonwoven FFP2 Melt Blown. This early research, headed by W.H. Carothers,Acrylic Flame Retardant Fabric, 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,Cinema Room Fabric. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Fireproof Wall Lining,Flame Retardant Fabric. 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 Baffle, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Diy Acoustic Baffles.

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,Acoustic Ceiling Baffle. In this process, ethylene is the polymer, the chemical building block of polyester,Acoustic Ceiling Panels.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Acoustic Ceiling Board. The four basic forms are filament,Polyester Sound Absorbing panels, tow, and fiberfill. In the filament form,Decorative Polyester Fiber Acoustic Panels, producing smooth-DIY Acoustic Panels.Polyester Acoustic Sound Panels, filaments are cut to short,Sound Absorbing Wall Panels.Studio 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.Custom Acoustic Panels.

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-Hexagon Polyester Acoustic Panel,Beveled Polyester Fiber Panel, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Polyester Acoustic Leaf. 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.Print Polyester Fiber Acoustic Panel, which are usually round,Polyester Sound Dampening Panels. The number of holes in the spinneret determines the size of the yarn,Art Board.
• 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,Polyester Fiber Felt. 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,Eco Friendly Wall Panel.
• Decorative Sound Polyester Fiber Acoustic Panels,Polyester Soundproofing Acoustic Panel. Also,Printed Polyester Fiber Acoustic Panel,Soundproof Polyester Fiber Acoustic Panels.

Winding

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

However, in the melt spinning process,Cartoon printing super mini 3 section rain umbrella. The rope-Cartoon Animal Children Umbrellas.

Drawing tow

• 1 Newly-Inverted Umbrella Double Layer Reverse Windproof.Kids Clear And Transparent POE Umbrella.

Crimping

• 2 Drawn tow is then fed into compression boxes,POE Animal Children Kids Umbrella, at a rate of 9-15 crimps per inch (3-6 per cm).Long Clear POE Rain Umbrella.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)POE Rain Umbrella.Portable Pocket Super Mini 3 Section Rain Umbrella.

Cutting

• 4 Following heat setting,Cartoon Printing Super Mini 3 section Rain 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)Black Compact Super Mini 3 Section Rain Umbrella.Super Mini Umbrella, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Promotional Manual Open Golf Umbrella.

The Future

Manual Open Golf Umbrella,Polyester Fabric Animal Children Umbrella's fastest-growing fiber.POE Animal Children Umbrella. 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,Fiberglass Long Automatic Children Umbrella, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,POE Long Automatic Children Umbrella. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.EVA Print Children Umbrella, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
