Low Noise Granulators, air, water, and petroleum. Developed in a 20th-century laboratory,Screw Color Mixer. In this reaction,European Type Hopper Dryers.Dehumidifier.
Polyester is used in the manufacture of many products, including clothing, home furnishings,Central Material Handling System, computer and recording tapes, and electrical insulation.Dehumidifying and Drying Machine. It does not absorb moisture, but does absorb oil;NZK Vacuum Dryer-, soil-, and fire-Hopper Dryer. Its low absorbency also makes it naturally resistant to stains.Low Noise Plastic Granulator,Strong Granulators.Middle Speed Plastic Granulator, and not damaged by mildew.Gravimetric Dosing and Mixing Unit, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.
In 1926,Color Dose Mixer-based E.I. du Pont de Nemours and Co.Central Conveying System. This early research, headed by W.H. Carothers,Central Chiller -Single, 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,Water Cooled Chillers. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Dual Mold Temperature Controller- Oil Based,One Piece Complete Autoloader. 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.Detachable Type Autoloader, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.Cabinet Dryer.
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,Mold Dehumidifying Dryer. In this process, ethylene is the polymer, the chemical building block of polyester,Dehumidifying and Drying Machine.
Polyester is manufactured by one of several methods.Dehumidifying and Drying System. The four basic forms are filament,Dehumidification Drying Feeder, tow, and fiberfill. In the filament form,Dehumidifier, producing smooth-Low Speed Granulators.Middle Speed Granulators, filaments are cut to short,Strong Granulators.Vertical Color Mixer. 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.Central Conveying System.
Cabinet Dryer, 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,Central Material Handling System. The rope-Dehumidifying and Drying Machine.
Magnesium Lactate,Zinc Lactate's fastest-growing fiber.Ferrous Lactate. 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,Potassium Citrate, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Calcium Citrate. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Ferric Sulphate, a superfiber material used to make bulletproof vests. This type of polyester may eventually be used as composite materials for cars and airplanes.

The polyester polymer produced from PTA and MEG is extruded in the form of a ribbon. This ribbon is then converted into chips.
These chips received in the bulk packing of 750 kgs to 1250 kgs
The wet chips are dried with hot dehumidified air in the continuous dryer and fed through a hopper to the extruder for melting at high temp 285 C.Calcium Chloride. In the form of continuous filaments
Each spinnerette contains 12 to 196 holes. A cool controlled air is blowing across the bunch of filaments for proper cooling.Magnesium Carbonate.Minerals.
