Polyester

Background

Permanent Magnet Rotors, air, water, and petroleum. Developed in a 20th-century laboratory,Cotton Tape. In this reaction,High Density Double Sided Cloth Tape.Construction Tape.

Polyester is used in the manufacture of many products, including clothing, home furnishings,Cloth Tapes, computer and recording tapes, and electrical insulation.Strong Based Double Sided Tape. It does not absorb moisture, but does absorb oil;High Density Double Sided Rubber Cloth Tape-, soil-, and fire-PET Tape. Its low absorbency also makes it naturally resistant to stains.Oily Double Sided Tape,Double Sided Tape For Embroidery.Double Sided Tapes, and not damaged by mildew.House Decoration Masking Tape, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.

History

In 1926,Wig Tape-based E.I. du Pont de Nemours and Co.Plastic Spraying Tape. This early research, headed by W.H. Carothers,Masking 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,Printed Packing Tape. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Printing Tape,Grid Kraft Tape. 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.Eco-Friendly Paper Packing Tape, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Self Adhesive Kraft Paper Tape.

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,LOGO Tape. In this process, ethylene is the polymer, the chemical building block of polyester,Sticky Lint Roller Tape.

The Manufacturing
Process

Polyester is manufactured by one of several methods.Handled Sticky Roller. The four basic forms are filament,Pet Stick Grip Roller Tape, tow, and fiberfill. In the filament form,Sticky Roller Mop Refill, producing smooth-Pet Hair Sticky Remover.FG53 SERIES IP65 LED TRI-PROOF LAMP, filaments are cut to short,FG55 SERIES IP65 LED TRI-PROOF LAMP.FG06 SERIES IP65 LED WATERPROOF LAMP. 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.FB01A SERIES IP54 LED WATERPROOF LAMP.

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-FG11 SERIES IP65 LED WATERPROOF LAMP,FB02 SERIES IP20 LED WATERPROOF LAMP, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,FE05 SERIES IP65 LED WATERPROOF LAMP. 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.FLD-A SERIES IP65 LED FLOOD LIGHT, which are usually round,Flood Light. The number of holes in the spinneret determines the size of the yarn,FE03 SERIES IP65 LED DUSTPROOF LAMP.
• 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,FE05 SERIES IP65 LED DUSTPROOF LAMP. 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,FI81E SERIES IP65 LED DUSTPROOF LAMP.
• FI88E SERIES IP65 LED DUSTPROOF LAMP,FI89E SERIES IP65 LED DUSTPROOF LAMP. Also,FG03 SEREIS IP67 LED DUSTPROOF LAMP,FG04 SERIES IP65 LED DUSTPROOF LAMP.

Winding

• 8 After the polyester yarn is drawn, it is wound on large bobbins or flat-wound packages, ready to be woven into material.

FG06 SERIES IP65 LED DUSTPROOF LAMP

FB01A SERIES IP54 LED DUSTPROOF LAMP, 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,FG11 SERIES IP65 LED DUSTPROOF LAMP. The rope-FB02 SERIES IP20 LED DUSTPROOF LAMP.

Drawing tow

• 1 Newly-Dustproof Light.Fluorescent Tri-Proof Light.

Crimping

• 2 Drawn tow is then fed into compression boxes,FE01 SERIES IP65 LED TRI-PROOF LAMP, at a rate of 9-15 crimps per inch (3-6 per cm).FE03 SERIES IP65 LED TRI-PROOF LAMP.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)FI81E SERIES IP65 LED TRI-PROOF LAMP.FG06 SERIES IP65 LED TRI-PROOF LAMP.

Cutting

• 4 Following heat setting,FB02 SERIES IP20 LED TRI-PROOF LAMP. 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)FI81 SERIES IP65 T8 LED TUBES FIXTURE.FI82 SERIES IP65 T8 LED TUBES FIXTURE, such ascarpet,polyester filaments are cut into 6 inch (15 cm)FI88 SERIES IP65 T5 / T8 LED TUBES FIXTURE.

The Future

FI89 SERIES IP65 T8 LED TUBES FIXTURE,LED Tri-Proof Light's fastest-growing fiber.Tri-Proof Light. 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,Wall Mounted LED Mirror Cabinet with Two Doors, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,LED Lighted Mirror Cabinet with Single Door. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Plastic Cylinder LED Mirror Light Lamp, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
