History

In 1926,Pipe Flange Insulation Kits-based E.I. du Pont de Nemours and Co.Phenolic Flange Insulation Kits. This early research, headed by W.H. Carothers,Flange Insulation Kits, 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,Piping Flange Isolating Gaskets and Kits. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Flange Insulation Gasket Kits,Piping Flange Isolating Gaskets and Kits. 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.Flange Isolating Gasket Kits, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Flange Insulation Kit Gasket.

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,High Temperature Flange Insulation Kits. In this process, ethylene is the polymer, the chemical building block of polyester,8 Flange Isolation Kit.

The Manufacturing
Process

Polyester is manufactured by one of several methods.6 Flange Insulation Kit. The four basic forms are filament,Phenolic Flange Insulation Kits, tow, and fiberfill. In the filament form,Pipeline Flange Insulation Kits, producing smooth-Phenolic Flange Insulation Kits.Flange Isolating Gasket Kits, filaments are cut to short,Flange Insulation Gasket Sets.Type D Flange Insulation Gasket Kit. 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.Neoprene Faced Phenolic Flange Insulation Gasket Kit.

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-Flange Insulating Gaskets,Velvet Fabric, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Leopard Snakeskin Pattern Jacquard Looped Sofa 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.Luxury Snake Skin Pattern Jacquard Looped Rayon Sofa Fabric, which are usually round,780GSM High Quality Weight Tiger Stripe Jacquard Cut Velvet Fabric. The number of holes in the spinneret determines the size of the yarn,Light Repellent Anti Fire Sofa 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,Sofa Fabric Home Textile Yarn Dyed Jacquard. 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,Embroidery Fabric.

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,100%Polyester Soft Chenille Fabric For Curtain, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Jacquard Curtain. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.JBL Two Faced complete Blackout Curtain Fabric For Bedroom, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
