History

In 1926,2021 New Design Luxury Velvet Fabric For Curtains-based E.I. du Pont de Nemours and Co.Cotton And Polyester Chenille Curtains For Living Room. This early research, headed by W.H. Carothers,100% Polyester Cotton Fabrics Curtain Upholstery, 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 1946,100%Polyester Soft Chenille Fabric For Curtain. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Jacquard Curtain,JBL Two Faced complete Blackout Curtain Fabric For Bedroom. 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.Automatic Fiber High Speed Rapier Machine, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Automatic Fabric Shuttle Changing Loom.

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,Shuttle Loom Machine. In this process, ethylene is the polymer, the chemical building block of polyester,Shuttle Loom Automatic Machine.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Shuttle Weaving Loom. The four basic forms are filament,Velveteen Automatic Shuttle Changing Loom, tow, and fiberfill. In the filament form,Shuttleless Rapier Loom Machine, producing smooth-GA736 Shuttleless Rapier Loom Machine.Textile Rapier Loom, filaments are cut to short,Weaving Machine Fiber Rapier Loom.Weaving Loom. 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.Rapier Loom In Weaving Machines.

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-GA736 Weaving Machine,Rapier Weaving Machine, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Rapier Machine. 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.Medical Mask Machine, which are usually round,Fabric Mask Machine. The number of holes in the spinneret determines the size of the yarn,Nonvoven Mask 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,Medical Mask Making Machine. 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,Mask Making Machine.
• Face Mask Maker Machine,Face Mask Machine. Also,Fully Automatic Disposable Non Woven Face Mask Making Machine,Disposable Medical Protective Auto Mask 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.

Medical Masks Making Machine

Disposable Face Medical Masks Making Machine, polymerization, drying, and melt spinning (steps 1-4 above) are much the same as in the manufacture of filament yarn. However, in the melt spinning process,Surgical Mask Machine. The rope-Disposable Medical Protective Mask Machine.

Crimping

• 2 Drawn tow is then fed into compression boxes,LCD Video Wall, at a rate of 9-15 crimps per inch (3-6 per cm).Touch Screen Displays.

Setting

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,Solar Powered TV, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Solar TVs. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.43 Inch Fitness Mirror Display, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
