History

In 1926,Leopard Snakeskin Pattern Jacquard Looped Sofa Fabric-based E.I. du Pont de Nemours and Co.Luxury Snake Skin Pattern Jacquard Looped Rayon Sofa Fabric. This early research, headed by W.H. Carothers,780GSM High Quality Weight Tiger Stripe Jacquard Cut Velvet Fabric, 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,Light Repellent Anti Fire Sofa Fabric. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Sofa Fabric Home Textile Yarn Dyed Jacquard,Embroidery Fabric. 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.30% RAYON 70%Polyester Jacquard Trims And Tapes, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.JBL Jacquard Cut Velvet New Design Border Trims.

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,Jacquard Trims. In this process, ethylene is the polymer, the chemical building block of polyester,Jacquard Velvet Cushion Cover.

The Manufacturing
Process

Polyester is manufactured by one of several methods.New Design Gold Printed Cushion Cover Decorative Pillow. The four basic forms are filament,Pillow Case Valentine Cushion Cover, tow, and fiberfill. In the filament form,Print Decorative Home Textile Cushion, producing smooth-Cushion Cover.Luxury Embroidery Sheer Fabric For Curtain, filaments are cut to short,Livingroom Sheers Curtain Fabric.Embroidery Luxury Sheer Fabric For 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.Embroider Sheers.

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-JBL Woven European Style White Sheer Fabric For Curtain,2021 JBL White Sheers Curtain, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Plain Sheers. 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.JBL Jacquard Fabric Sheers Curtain, which are usually round,Bedroom Simple Modern Style Curtains. The number of holes in the spinneret determines the size of the yarn,European Style Decorative Sheers 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,2021 New Design Luxury Velvet Fabric For Curtains. 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,Cotton And Polyester Chenille Curtains For Living Room.
• 100% Polyester Cotton Fabrics Curtain Upholstery,100%Polyester Soft Chenille Fabric For Curtain. Also,Jacquard Curtain,JBL Two Faced complete Blackout Curtain Fabric For Bedroom.

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,Shuttleless Rapier Loom Machine, at a rate of 9-15 crimps per inch (3-6 per cm).GA736 Shuttleless Rapier Loom Machine.

Setting

The Future

Rapier Machine,Medical Mask Machine's fastest-growing fiber.Fabric 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,Nonvoven Mask Machine, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Medical Mask Making Machine. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Mask 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.
