History

In 1926,100%Polyester Soft Chenille Fabric For Curtain-based E.I. du Pont de Nemours and Co.Jacquard Curtain. This early research, headed by W.H. Carothers,JBL Two Faced complete Blackout Curtain Fabric For Bedroom, 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,Automatic Fiber High Speed Rapier Machine. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Automatic Fabric Shuttle Changing Loom,Shuttle Loom Machine. 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.Shuttle Loom Automatic Machine, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Shuttle Weaving Loom.

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,Velveteen Automatic Shuttle Changing Loom. In this process, ethylene is the polymer, the chemical building block of polyester,Shuttleless Rapier Loom Machine.

The Manufacturing
Process

Polyester is manufactured by one of several methods.GA736 Shuttleless Rapier Loom Machine. The four basic forms are filament,Textile Rapier Loom, tow, and fiberfill. In the filament form,Weaving Machine Fiber Rapier Loom, producing smooth-Weaving Loom.Rapier Loom In Weaving Machines, filaments are cut to short,GA736 Weaving Machine.Rapier Weaving Machine. 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.Rapier Machine.

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-Medical Mask Machine,Fabric Mask Machine, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Nonvoven Mask Machine. 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.Medical Mask Making Machine, which are usually round,Mask Making Machine. The number of holes in the spinneret determines the size of the yarn,Face Mask Maker Machine.
• 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,Face Mask Machine. 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,Fully Automatic Disposable Non Woven Face Mask Making Machine.
• Disposable Medical Protective Auto Mask Machine,Medical Masks Making Machine. Also,Disposable Face Medical Masks Making Machine,Surgical Mask Machine.

Winding

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

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Low Power Consumption Solar TV.24 Inch Paygo Solar TV.

Cutting

The Future

Solar Powered TV,Solar TVs's fastest-growing fiber.43 Inch Fitness Mirror Display. 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,Fitness Mirror, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Yacht TV. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Marine TV For Sale, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
