History

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

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

The Manufacturing
Process

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

Drying

• 3 After the polyester emerges from polymerization,GA736 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 Weaving Machine, which are usually round,Rapier Machine. The number of holes in the spinneret determines the size of the yarn,Medical 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,Fabric 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,Nonvoven Mask Machine.
• Medical Mask Making Machine,Mask Making Machine. Also,Face Mask Maker Machine,Face 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.

Crimping

• 2 Drawn tow is then fed into compression boxes,Gauze Weaving Loom, at a rate of 9-15 crimps per inch (3-6 per cm).Towel Weaving Loom.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)LCD Video Wall.Touch Screen Displays.

Cutting

Polyester that will be blended with cotton is cut in 1.25-1.50 inch (3.2-3.8 cm) pieces; for rayon blends, 2 inch (5 cm)Touch Inquiry Displays.Kiosk, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Low Power Consumption Solar TV.

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,Paygo Solar TV, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,24 Inch Solar Powered TV. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Solar Powered TV, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
