History

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

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,Jacquard Curtain. In this process, ethylene is the polymer, the chemical building block of polyester,JBL Two Faced complete Blackout Curtain Fabric For Bedroom.

The Manufacturing
Process

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

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-Textile Rapier Loom,Weaving Machine Fiber Rapier Loom, is extruded through a slot to form long ribbons.

Drying

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

Face Mask Maker Machine

Face Mask Machine, polymerization, drying, and melt spinning (steps 1-4 above) are much the same as in the manufacture of filament yarn. However, in the melt spinning process,Fully Automatic Disposable Non Woven Face Mask Making Machine. The rope-Disposable Medical Protective Auto Mask Machine.

Crimping

• 2 Drawn tow is then fed into compression boxes,Surgical Mask Machine, at a rate of 9-15 crimps per inch (3-6 per cm).Disposable Medical Protective Mask Machine.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Gauze Weaving Loom.Towel Weaving Loom.

Cutting

• 4 Following heat setting,LCD Video Wall. 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 Screen Displays.22 Inch Touch Inquiry Displays, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Touch Inquiry Displays.

The Future

Kiosk,Low Power Consumption Solar TV's fastest-growing fiber.24 Inch Paygo Solar TV. 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,32 Inch Paygo Solar TV, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,40 Inch Paygo Solar TV. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Paygo Solar TV, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
