Background

Strong Based Double Sided Tape, air, water, and petroleum. Developed in a 20th-century laboratory,High Density Double Sided Rubber Cloth Tape. In this reaction,PET Tape.Oily Double Sided Tape.

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

History

In 1926,Grid Kraft Tape-based E.I. du Pont de Nemours and Co.Eco-Friendly Paper Packing Tape. This early research, headed by W.H. Carothers,Self Adhesive Kraft Paper Tape, 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,LOGO Tape. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Sticky Lint Roller Tape,Handled Sticky Roller. 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.Pet Stick Grip Roller Tape, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Sticky Roller Mop Refill.

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,Pet Hair Sticky Remover. In this process, ethylene is the polymer, the chemical building block of polyester,FG53 SERIES IP65 LED TRI-PROOF LAMP.

The Manufacturing
Process

Polyester is manufactured by one of several methods.FG55 SERIES IP65 LED TRI-PROOF LAMP. The four basic forms are filament,FG06 SERIES IP65 LED WATERPROOF LAMP, tow, and fiberfill. In the filament form,FB01A SERIES IP54 LED WATERPROOF LAMP, producing smooth-FG11 SERIES IP65 LED WATERPROOF LAMP.FB02 SERIES IP20 LED WATERPROOF LAMP, filaments are cut to short,FE05 SERIES IP65 LED WATERPROOF LAMP.FLD-A SERIES IP65 LED FLOOD LIGHT. 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.Flood Light.

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-FE03 SERIES IP65 LED DUSTPROOF LAMP,FE05 SERIES IP65 LED DUSTPROOF LAMP, is extruded through a slot to form long ribbons.

Drying

• 3 After the polyester emerges from polymerization,FI81E SERIES IP65 LED DUSTPROOF 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.FI88E SERIES IP65 LED DUSTPROOF LAMP, which are usually round,FI89E SERIES IP65 LED DUSTPROOF LAMP. The number of holes in the spinneret determines the size of the yarn,FG03 SEREIS IP67 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,FG04 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,FG06 SERIES IP65 LED DUSTPROOF LAMP.
• FB01A SERIES IP54 LED DUSTPROOF LAMP,FG11 SERIES IP65 LED DUSTPROOF LAMP. Also,FB02 SERIES IP20 LED DUSTPROOF LAMP,Dustproof Light.

Winding

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

Fluorescent Tri-Proof Light

FE01 SERIES IP65 LED TRI-PROOF 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,FE03 SERIES IP65 LED TRI-PROOF LAMP. The rope-FI81E SERIES IP65 LED TRI-PROOF LAMP.

Drawing tow

• 1 Newly-FG06 SERIES IP65 LED TRI-PROOF LAMP.FB02 SERIES IP20 LED TRI-PROOF LAMP.

Crimping

• 2 Drawn tow is then fed into compression boxes,FI81 SERIES IP65 T8 LED TUBES FIXTURE, at a rate of 9-15 crimps per inch (3-6 per cm).FI82 SERIES IP65 T8 LED TUBES FIXTURE.

Setting

• 3 After the tow is crimped, it is heated at 212-302°F (100-150°C)FI88 SERIES IP65 T5 / T8 LED TUBES FIXTURE.FI89 SERIES IP65 T8 LED TUBES FIXTURE.

Cutting

• 4 Following heat setting,LED Tri-Proof Light. 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)Tri-Proof Light.Wall Mounted LED Mirror Cabinet with Two Doors, such ascarpet,polyester filaments are cut into 6 inch (15 cm)LED Lighted Mirror Cabinet with Single Door.

The Future

Plastic Cylinder LED Mirror Light Lamp,Stainless Square LED Mirror Light Lamp's fastest-growing fiber.LED Mirror 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,Oval LED Dressing Mirror, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Rectangle LED Dressing Mirror With Two Frosted Light Strips. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Full Length Backlit Rectangle LED Dressing Mirror, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.
