History

In 1926,European Style Decorative Sheers Curtain-based E.I. du Pont de Nemours and Co.2021 New Design Luxury Velvet Fabric For Curtains. This early research, headed by W.H. Carothers,Cotton And Polyester Chenille Curtains For Living Room, 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 1946,100% Polyester Cotton Fabrics Curtain Upholstery. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.100%Polyester Soft Chenille Fabric For Curtain,Jacquard Curtain. 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.JBL Two Faced complete Blackout Curtain Fabric For Bedroom, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Automatic Fiber High Speed Rapier Machine.

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

The Manufacturing
Process

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

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-Rapier Loom In Weaving Machines,GA736 Weaving Machine, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Rapier Weaving 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.Rapier Machine, which are usually round,Medical Mask Machine. The number of holes in the spinneret determines the size of the yarn,Fabric 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,Nonvoven 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,Medical Mask Making 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,24 Inch Solar Powered TV, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Solar Powered TV. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Solar TVs, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
