History

In 1926,Pillow Case Valentine Cushion Cover-based E.I. du Pont de Nemours and Co.Print Decorative Home Textile Cushion. This early research, headed by W.H. Carothers,Cushion Cover, 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,Luxury Embroidery Sheer Fabric For Curtain. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Livingroom Sheers Curtain Fabric,Embroidery Luxury Sheer 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.Embroider Sheers, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.JBL Woven European Style White Sheer 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,2021 JBL White Sheers Curtain. In this process, ethylene is the polymer, the chemical building block of polyester,Plain Sheers.

The Manufacturing
Process

Polyester is manufactured by one of several methods.JBL Jacquard Fabric Sheers Curtain. The four basic forms are filament,Bedroom Simple Modern Style Curtains, tow, and fiberfill. In the filament form,European Style Decorative Sheers Curtain, producing smooth-2021 New Design Luxury Velvet Fabric For Curtains.Cotton And Polyester Chenille Curtains For Living Room, filaments are cut to short,100% Polyester Cotton Fabrics Curtain Upholstery.100%Polyester Soft Chenille Fabric For Curtain. 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.Jacquard Curtain.

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-JBL Two Faced complete Blackout Curtain Fabric For Bedroom,Automatic Fiber High Speed Rapier Machine, is extruded through a slot to form long ribbons.

Drying

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

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,Nonvoven Mask Machine, at a rate of 9-15 crimps per inch (3-6 per cm).Medical Mask Making Machine.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Mask Making Machine.Face Mask Maker Machine.

Cutting

• 4 Following heat setting,Face Mask 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)Fully Automatic Disposable Non Woven Face Mask Making Machine.Disposable Medical Protective Auto Mask Machine, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Medical Masks Making Machine.

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,Gauze Weaving Loom, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Towel Weaving Loom. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.LCD Video Wall, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
