History

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

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

The Manufacturing
Process

Polyester is manufactured by one of several methods.Embroidery Luxury Sheer Fabric For Curtain. The four basic forms are filament,Embroider Sheers, tow, and fiberfill. In the filament form,JBL Woven European Style White Sheer Fabric For Curtain, producing smooth-2021 JBL White Sheers Curtain.Plain Sheers, filaments are cut to short,JBL Jacquard Fabric Sheers Curtain.Bedroom Simple Modern Style Curtains. 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.European Style Decorative Sheers 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-2021 New Design Luxury Velvet Fabric For Curtains,Cotton And Polyester Chenille Curtains For Living Room, is extruded through a slot to form long ribbons.

Drying

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

Setting

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

Cutting

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

The Future

Face Mask Maker Machine,Face Mask Machine's fastest-growing fiber.Fully Automatic Disposable Non Woven Face Mask Making 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,Disposable Medical Protective Auto Mask Machine, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Medical Masks Making Machine. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Disposable Face 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.
