History

In 1926,Luxury Embroidery Sheer Fabric For Curtain-based E.I. du Pont de Nemours and Co.Livingroom Sheers Curtain Fabric. This early research, headed by W.H. Carothers,Embroidery Luxury Sheer Fabric For Curtain, 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,Embroider Sheers. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.JBL Woven European Style White Sheer Fabric For Curtain,2021 JBL White Sheers Curtain. 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.Plain Sheers, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.JBL Jacquard Fabric Sheers 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,Bedroom Simple Modern Style Curtains. In this process, ethylene is the polymer, the chemical building block of polyester,European Style Decorative Sheers Curtain.

The Manufacturing
Process

Polyester is manufactured by one of several methods.2021 New Design Luxury Velvet Fabric For Curtains. The four basic forms are filament,Cotton And Polyester Chenille Curtains For Living Room, tow, and fiberfill. In the filament form,100% Polyester Cotton Fabrics Curtain Upholstery, producing smooth-100%Polyester Soft Chenille Fabric For Curtain.Jacquard Curtain, filaments are cut to short,JBL Two Faced complete Blackout Curtain Fabric For Bedroom.Automatic Fiber High Speed Rapier Machine. 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.Automatic Fabric Shuttle Changing Loom.

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-Shuttle Loom Machine,Shuttle Loom Automatic Machine, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Shuttle Weaving Loom. 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.Velveteen Automatic Shuttle Changing Loom, which are usually round,Shuttleless Rapier Loom Machine. The number of holes in the spinneret determines the size of the yarn,GA736 Shuttleless Rapier Loom 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,Textile Rapier 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,Weaving Machine Fiber Rapier Loom.
• Weaving Loom,Rapier Loom In Weaving Machines. Also,GA736 Weaving Machine,Rapier Weaving 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.

Rapier Machine

The Future

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,Touch Screen Displays, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,22 Inch Touch Inquiry Displays. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Touch Inquiry Displays, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
