History

In 1926,Jacquard Curtain-based E.I. du Pont de Nemours and Co.JBL Two Faced complete Blackout Curtain Fabric For Bedroom. This early research, headed by W.H. Carothers,Automatic Fiber High Speed Rapier Machine, 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 Fabric Shuttle Changing Loom. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Shuttle Loom Machine,Shuttle Loom Automatic 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 Weaving Loom, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Velveteen Automatic Shuttle Changing 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,Shuttleless Rapier Loom Machine. In this process, ethylene is the polymer, the chemical building block of polyester,GA736 Shuttleless Rapier Loom Machine.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Textile Rapier Loom. The four basic forms are filament,Weaving Machine Fiber Rapier Loom, tow, and fiberfill. In the filament form,Weaving Loom, producing smooth-Rapier Loom In Weaving Machines.GA736 Weaving Machine, filaments are cut to short,Rapier Weaving Machine.Rapier 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.Medical Mask 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-Fabric Mask Machine,Nonvoven Mask Machine, is extruded through a slot to form long ribbons.

Drying

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

The Future

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,Yacht TV, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Marine TV For Sale. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Marine TV, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
