History

In 1926,Livingroom Sheers Curtain Fabric-based E.I. du Pont de Nemours and Co.Embroidery Luxury Sheer Fabric For Curtain. This early research, headed by W.H. Carothers,Embroider Sheers, 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,JBL Woven European Style White Sheer Fabric For Curtain. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.2021 JBL White Sheers Curtain,Plain Sheers. 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.JBL Jacquard Fabric Sheers Curtain, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Bedroom Simple Modern Style Curtains.

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,European Style Decorative Sheers Curtain. In this process, ethylene is the polymer, the chemical building block of polyester,2021 New Design Luxury Velvet Fabric For Curtains.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Cotton And Polyester Chenille Curtains For Living Room. The four basic forms are filament,100% Polyester Cotton Fabrics Curtain Upholstery, tow, and fiberfill. In the filament form,100%Polyester Soft Chenille Fabric For Curtain, producing smooth-Jacquard Curtain.JBL Two Faced complete Blackout Curtain Fabric For Bedroom, filaments are cut to short,Automatic Fiber High Speed Rapier Machine.Automatic Fabric Shuttle Changing 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.Shuttle 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-Shuttle Loom Automatic Machine,Shuttle Weaving Loom, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Velveteen Automatic Shuttle Changing 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.Shuttleless Rapier Loom Machine, which are usually round,GA736 Shuttleless Rapier Loom Machine. The number of holes in the spinneret determines the size of the yarn,Textile Rapier Loom.
• 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,Weaving Machine Fiber Rapier Loom. 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,Weaving Loom.
• Rapier Loom In Weaving Machines,GA736 Weaving Machine. Also,Rapier Weaving Machine,Rapier 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.

Medical Mask Machine

Fabric 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,Nonvoven Mask Machine. The rope-Medical Mask Making Machine.

Drawing tow

Crimping

• 2 Drawn tow is then fed into compression boxes,Face Mask Machine, at a rate of 9-15 crimps per inch (3-6 per cm).Fully Automatic Disposable Non Woven Face Mask Making Machine.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Disposable Medical Protective Auto Mask Machine.Medical Masks Making Machine.

Cutting

• 4 Following heat setting,Disposable Face Medical Masks Making Machine. 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)Surgical Mask Machine.Disposable Medical Protective Mask Machine, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Gauze Weaving Loom.

The Future

Towel Weaving Loom,LCD Video Wall's fastest-growing fiber.Touch Screen Displays. 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,22 Inch Touch Inquiry Displays, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Touch Inquiry Displays. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Kiosk, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
