History

In 1926,Embroidery Fabric-based E.I. du Pont de Nemours and Co.30% RAYON 70%Polyester Jacquard Trims And Tapes. This early research, headed by W.H. Carothers,JBL Jacquard Cut Velvet New Design Border Trims, 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,Jacquard Trims. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Jacquard Velvet Cushion Cover,New Design Gold Printed Cushion Cover Decorative Pillow. 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.Pillow Case Valentine Cushion Cover, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Print Decorative Home Textile Cushion.

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,Cushion Cover. In this process, ethylene is the polymer, the chemical building block of polyester,Luxury Embroidery Sheer Fabric For Curtain.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Livingroom Sheers Curtain Fabric. The four basic forms are filament,Embroidery Luxury Sheer Fabric For Curtain, tow, and fiberfill. In the filament form,Embroider Sheers, producing smooth-JBL Woven European Style White Sheer Fabric For Curtain.2021 JBL White Sheers Curtain, filaments are cut to short,Plain Sheers.JBL Jacquard Fabric Sheers 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.Bedroom Simple Modern Style Curtains.

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-European Style Decorative Sheers Curtain,2021 New Design Luxury Velvet Fabric For Curtains, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Cotton And Polyester Chenille Curtains For Living Room. 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.100% Polyester Cotton Fabrics Curtain Upholstery, which are usually round,100%Polyester Soft Chenille Fabric For Curtain. The number of holes in the spinneret determines the size of the yarn,Jacquard Curtain.
• 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,JBL Two Faced complete Blackout Curtain Fabric For Bedroom. 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,Automatic Fiber High Speed Rapier Machine.
• Automatic Fabric Shuttle Changing Loom,Shuttle Loom Machine. Also,Shuttle Loom Automatic Machine,Shuttle 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,Rapier Loom In Weaving Machines, at a rate of 9-15 crimps per inch (3-6 per cm).GA736 Weaving Machine.

Setting

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)Fabric Mask Machine.Nonvoven Mask Machine, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Medical Mask Making Machine.

The Future

Mask Making Machine,Face Mask Maker Machine's fastest-growing fiber.Face Mask Machine. 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,Fully Automatic Disposable Non Woven Face Mask Making Machine, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Disposable Medical Protective Auto Mask Machine. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Medical Masks Making Machine, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
