History

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

The Manufacturing
Process

Polyester is manufactured by one of several methods.Pillow Case Valentine Cushion Cover. The four basic forms are filament,Print Decorative Home Textile Cushion, tow, and fiberfill. In the filament form,Cushion Cover, producing smooth-Luxury Embroidery Sheer Fabric For Curtain.Livingroom Sheers Curtain Fabric, filaments are cut to short,Embroidery Luxury Sheer Fabric For Curtain.Embroider Sheers. 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.JBL Woven European Style White 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-2021 JBL White Sheers Curtain,Plain Sheers, is extruded through a slot to form long ribbons.

Drying

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

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

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