History

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

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,JBL Jacquard Fabric Sheers Curtain. In this process, ethylene is the polymer, the chemical building block of polyester,Bedroom Simple Modern Style Curtains.

The Manufacturing
Process

Polyester is manufactured by one of several methods.European Style Decorative Sheers Curtain. The four basic forms are filament,2021 New Design Luxury Velvet Fabric For Curtains, tow, and fiberfill. In the filament form,Cotton And Polyester Chenille Curtains For Living Room, producing smooth-100% Polyester Cotton Fabrics Curtain Upholstery.100%Polyester Soft Chenille Fabric For Curtain, filaments are cut to short,Jacquard Curtain.JBL Two Faced complete Blackout Curtain Fabric For Bedroom. 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.Automatic Fiber High Speed Rapier 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-Automatic Fabric Shuttle Changing Loom,Shuttle Loom Machine, is extruded through a slot to form long ribbons.

Drying

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

Rapier Weaving Machine

Rapier 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,Medical Mask Machine. The rope-Fabric Mask Machine.

Drawing tow

• 1 Newly-Nonvoven Mask Machine.Medical Mask Making Machine.

Crimping

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

Setting

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

Cutting

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

The Future

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