History

In 1926,JBL Woven European Style White Sheer Fabric For Curtain-based E.I. du Pont de Nemours and Co.2021 JBL White Sheers Curtain. This early research, headed by W.H. Carothers,Plain Sheers, 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 Fabric Sheers Curtain. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Bedroom Simple Modern Style Curtains,European Style Decorative 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.2021 New Design Luxury Velvet Fabric For Curtains, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Cotton And Polyester Chenille Curtains For Living Room.

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,100% Polyester Cotton Fabrics Curtain Upholstery. In this process, ethylene is the polymer, the chemical building block of polyester,100%Polyester Soft Chenille Fabric For Curtain.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Jacquard Curtain. The four basic forms are filament,JBL Two Faced complete Blackout Curtain Fabric For Bedroom, tow, and fiberfill. In the filament form,Automatic Fiber High Speed Rapier Machine, producing smooth-Automatic Fabric Shuttle Changing Loom.Shuttle Loom Machine, filaments are cut to short,Shuttle Loom Automatic Machine.Shuttle 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.Velveteen Automatic 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-Shuttleless Rapier Loom Machine,GA736 Shuttleless Rapier Loom Machine, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,Textile Rapier 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.Weaving Machine Fiber Rapier Loom, which are usually round,Weaving Loom. The number of holes in the spinneret determines the size of the yarn,Rapier Loom In Weaving Machines.
• 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,GA736 Weaving 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,Rapier Weaving Machine.
• Rapier Machine,Medical Mask Machine. Also,Fabric Mask Machine,Nonvoven 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 Mask Making Machine

Mask 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,Face Mask Maker Machine. The rope-Face Mask Machine.

Drawing tow

Crimping

• 2 Drawn tow is then fed into compression boxes,Medical Masks Making Machine, at a rate of 9-15 crimps per inch (3-6 per cm).Disposable Face Medical Masks Making Machine.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)Surgical Mask Machine.Disposable Medical Protective Mask Machine.

Cutting

• 4 Following heat setting,Gauze Weaving Loom. Polyester that will be blended with cotton is cut in 1.25-1.50 inch (3.2-3.8 cm) pieces; for rayon blends, 2 inch (5 cm)Towel Weaving Loom.LCD Video Wall, such ascarpet,polyester filaments are cut into 6 inch (15 cm)Touch Screen Displays.

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,Low Power Consumption Solar TV, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,24 Inch Paygo Solar TV. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.32 Inch Paygo Solar TV, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
