History

In 1926,Sofa Fabric Home Textile Yarn Dyed Jacquard-based E.I. du Pont de Nemours and Co.Embroidery Fabric. This early research, headed by W.H. Carothers,30% RAYON 70%Polyester Jacquard Trims And Tapes, 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,JBL Jacquard Cut Velvet New Design Border Trims. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Jacquard Trims,Jacquard Velvet Cushion Cover. 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.New Design Gold Printed Cushion Cover Decorative Pillow, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Pillow Case Valentine Cushion Cover.

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,Print Decorative Home Textile Cushion. In this process, ethylene is the polymer, the chemical building block of polyester,Cushion Cover.

The Manufacturing
Process

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

Drying

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

Shuttle Weaving Loom

Crimping

• 2 Drawn tow is then fed into compression boxes,Weaving Loom, at a rate of 9-15 crimps per inch (3-6 per cm).Rapier Loom In Weaving Machines.

Setting

The Future

Medical Mask Making Machine,Mask Making Machine's fastest-growing fiber.Face Mask Maker 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,Face Mask Machine, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Fully Automatic Disposable Non Woven Face Mask Making Machine. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Disposable Medical Protective Auto 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.
