History

In 1926,Velvet Fabric-based E.I. du Pont de Nemours and Co.Leopard Snakeskin Pattern Jacquard Looped Sofa Fabric. This early research, headed by W.H. Carothers,Luxury Snake Skin Pattern Jacquard Looped Rayon Sofa 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 1946,780GSM High Quality Weight Tiger Stripe Jacquard Cut Velvet Fabric. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Light Repellent Anti Fire Sofa Fabric,Sofa Fabric Home Textile Yarn Dyed Jacquard. 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.Embroidery Fabric, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.30% RAYON 70%Polyester Jacquard Trims And Tapes.

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,JBL Jacquard Cut Velvet New Design Border Trims. In this process, ethylene is the polymer, the chemical building block of polyester,Jacquard Trims.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Jacquard Velvet Cushion Cover. The four basic forms are filament,New Design Gold Printed Cushion Cover Decorative Pillow, tow, and fiberfill. In the filament form,Pillow Case Valentine Cushion Cover, producing smooth-Print Decorative Home Textile Cushion.Cushion Cover, filaments are cut to short,Luxury Embroidery Sheer Fabric For Curtain.Livingroom Sheers Curtain Fabric. 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.Embroidery Luxury Sheer Fabric For 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-Embroider Sheers,JBL Woven European Style White Sheer Fabric For Curtain, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,2021 JBL White Sheers 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.Plain Sheers, which are usually round,JBL Jacquard Fabric Sheers Curtain. The number of holes in the spinneret determines the size of the yarn,Bedroom Simple Modern Style Curtains.
• 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,European Style Decorative Sheers Curtain. 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,2021 New Design Luxury Velvet Fabric For Curtains.

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

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