Background

Type of CNC Machines, air, water, and petroleum. Developed in a 20th-century laboratory,Copper Nut. In this reaction,Brass nut.Automatic Machine Parts.

Polyester is used in the manufacture of many products, including clothing, home furnishings,Balance Shaft for Cars, computer and recording tapes, and electrical insulation.Metal Parts Manufacturer. It does not absorb moisture, but does absorb oil;Electric Toothbrush Parts-, soil-, and fire-Forehead Thermometer Parts. Its low absorbency also makes it naturally resistant to stains.Automobile Electric Solenoid Valve,Face Mask Machine Parts.Massage Chair Parts, and not damaged by mildew.Massage Push Rod of Chair, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,Small radar cover-based E.I. du Pont de Nemours and Co.Twist Pin. This early research, headed by W.H. Carothers,Electronic Cigarette Retainer Ring, 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,Cutter Shaft of Mower. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Electronic Cigarette Base,Electronic Cigarette Retainer Ring Neck. 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.Auto Engine Parts, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Mouthpiece for Electronics Cigarettes.

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,Electronic Cigarette Holder. In this process, ethylene is the polymer, the chemical building block of polyester,Custom Steel Turning Parts.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Automobile Air Conditioner Parts. The four basic forms are filament,3D Printer Parts Heater Block, tow, and fiberfill. In the filament form,Car Air Conditioner Parts, producing smooth-Car Air Conditioner Spare Parts.Brass connector, filaments are cut to short,Connecting Base.Gear Shaft. 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.Round Acoustic Fabric Wrapped Panelas.

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-N95 Meltblown Nonwoven Fabric,FFP3 Meltblown Nonwoven Fabric, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,KF94 Meltblown Nonwoven Fabric. 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.PFE 95 Meltblown Nonwoven Fabric, which are usually round,High Filtration Nonwoven FFP2 Melt Blown. The number of holes in the spinneret determines the size of the yarn,Acrylic Flame Retardant Fabric.
• 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,Cinema Room Fabric. 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,Fireproof Wall Lining.
• Flame Retardant Fabric,Polyester Sound Baffle. Also,Diy Acoustic Baffles,Acoustic Ceiling Baffle.

Winding

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

Acoustic Ceiling Panels

Acoustic Ceiling Board, 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 Sound Absorbing panels. The rope-Decorative Polyester Fiber Acoustic Panels.

Drawing tow

• 1 Newly-DIY Acoustic Panels.Polyester Acoustic Sound Panels.

Crimping

• 2 Drawn tow is then fed into compression boxes,Sound Absorbing Wall Panels, at a rate of 9-15 crimps per inch (3-6 per cm).Studio acoustic Panel.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Custom Acoustic Panels.Hexagon Polyester Acoustic Panel.

Cutting

• 4 Following heat setting,Beveled Polyester Fiber Panel. 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)Polyester Acoustic Leaf.Print Polyester Fiber Acoustic Panel, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Polyester Sound Dampening Panels.

The Future

Art Board,Polyester Fiber Felt's fastest-growing fiber.Eco Friendly Wall Panel. 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,Decorative Sound Polyester Fiber Acoustic Panels, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Polyester Soundproofing Acoustic Panel. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Printed Polyester Fiber Acoustic Panel, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
