History

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

The Manufacturing
Process

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

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 Fiber High Speed Rapier Machine,Automatic Fabric Shuttle Changing Loom, is extruded through a slot to form long ribbons.

Drying

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

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

Drawing tow

• 1 Newly-Fabric Mask Machine.Nonvoven Mask Machine.

Crimping

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

Setting

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

Cutting

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

The Future

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