History

In 1926,Cartoon printing super mini 3 section rain umbrella-based E.I. du Pont de Nemours and Co.Cartoon Animal Children Umbrellas. This early research, headed by W.H. Carothers,Inverted Umbrella Double Layer Reverse Windproof, 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,Kids Clear And Transparent POE Umbrella. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.POE Animal Children Kids Umbrella,Long Clear POE Rain Umbrella. 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.POE Rain Umbrella, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Portable Pocket Super Mini 3 Section Rain Umbrella.

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,Cartoon Printing Super Mini 3 section Rain Umbrella. In this process, ethylene is the polymer, the chemical building block of polyester,Black Compact Super Mini 3 Section Rain Umbrella.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Super Mini Umbrella. The four basic forms are filament,Promotional Manual Open Golf Umbrella, tow, and fiberfill. In the filament form,Manual Open Golf Umbrella, producing smooth-Polyester Fabric Animal Children Umbrella.POE Animal Children Umbrella, filaments are cut to short,Fiberglass Long Automatic Children Umbrella.POE Long Automatic Children Umbrella. 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.EVA Print Children Umbrella.

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-Manual Open Adult Wooden Stick Umbrella,Rainbow Adult Stick Automatic Umbrella, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Special Rainbow Edge Long Adult Stick Umbrella. 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.Double Layer Special Adult Stick Umbrella, which are usually round,Automatic Long Stick Rain Umbrellas. The number of holes in the spinneret determines the size of the yarn,Gent Folding Super Mini Manual Open Umbrella.
• 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,Folding Manual Open Umbrella. 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,Wooden Two Folding Automatic Golf Umbrella.

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,Antique Metal Planter Pot with Stands Décor, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Metal Planter. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Rectangular MDF Wood Planter, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
