History

In 1926,Type D Flange Insulation Gasket Kit-based E.I. du Pont de Nemours and Co.Neoprene Faced Phenolic Flange Insulation Gasket Kit. This early research, headed by W.H. Carothers,Flange Insulating Gaskets, 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,Velvet Fabric. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Leopard Snakeskin Pattern Jacquard Looped Sofa Fabric,Luxury Snake Skin Pattern Jacquard Looped Rayon Sofa 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.780GSM High Quality Weight Tiger Stripe Jacquard Cut Velvet Fabric, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Light Repellent Anti Fire Sofa Fabric.

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,Sofa Fabric Home Textile Yarn Dyed Jacquard. In this process, ethylene is the polymer, the chemical building block of polyester,Embroidery Fabric.

The Manufacturing
Process

Polyester is manufactured by one of several methods.30% RAYON 70%Polyester Jacquard Trims And Tapes. The four basic forms are filament,JBL Jacquard Cut Velvet New Design Border Trims, tow, and fiberfill. In the filament form,Jacquard Trims, producing smooth-Jacquard Velvet Cushion Cover.New Design Gold Printed Cushion Cover Decorative Pillow, filaments are cut to short,Pillow Case Valentine Cushion Cover.Print Decorative Home Textile Cushion. 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.Cushion Cover.

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-Luxury Embroidery Sheer Fabric For Curtain,Livingroom Sheers Curtain Fabric, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Embroidery Luxury Sheer Fabric For Curtain. 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.Embroider Sheers, which are usually round,JBL Woven European Style White Sheer Fabric For Curtain. The number of holes in the spinneret determines the size of the yarn,2021 JBL White Sheers Curtain.
• 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,Plain Sheers. 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,JBL Jacquard Fabric Sheers Curtain.

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