History

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

The Manufacturing
Process

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

Drying

• 3 After the polyester emerges from polymerization,100%Polyester Soft Chenille Fabric For Curtain. 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.Jacquard Curtain, which are usually round,JBL Two Faced complete Blackout Curtain Fabric For Bedroom. The number of holes in the spinneret determines the size of the yarn,Automatic Fiber High Speed Rapier 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,Automatic Fabric Shuttle Changing Loom. 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 Loom Machine.
• Shuttle Loom Automatic Machine,Shuttle Weaving Loom. Also,Velveteen Automatic Shuttle Changing Loom,Shuttleless Rapier Loom 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.

The Future

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