History

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

The Manufacturing
Process

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

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-100%Polyester Soft Chenille Fabric For Curtain,Jacquard Curtain, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,JBL Two Faced complete Blackout Curtain Fabric For Bedroom. 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.Automatic Fiber High Speed Rapier Machine, which are usually round,Automatic Fabric Shuttle Changing Loom. The number of holes in the spinneret determines the size of the yarn,Shuttle 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,Shuttle Loom Automatic 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,Shuttle Weaving Loom.
• Velveteen Automatic Shuttle Changing Loom,Shuttleless Rapier Loom Machine. Also,GA736 Shuttleless Rapier Loom Machine,Textile Rapier 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.

Weaving Machine Fiber Rapier Loom

Weaving Loom, 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 Loom In Weaving Machines. The rope-GA736 Weaving Machine.

Crimping

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

Setting

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

Cutting

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

The Future

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