Central Conveying System, air, water, and petroleum. Developed in a 20th-century laboratory,Mixer. In this reaction,Mold Temperature Controller-Water Based.Dual Mold Temperature Controller-Water Based.
Polyester is used in the manufacture of many products, including clothing, home furnishings,Central Chiller Dual Machine, computer and recording tapes, and electrical insulation.TCOD Oil Type Mold Temperature Machine. It does not absorb moisture, but does absorb oil;TCHW A cold and hot integrated temperature controller-, soil-, and fire-Heating and Cooling. Its low absorbency also makes it naturally resistant to stains.Self Contained Vacuum Hopper Loaders,Detachable Type Autoloader.European Type Hopper Dryers, and not damaged by mildew.Dehumidification Drying Feeder, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.
In 1926,Dehumidifying and Drying System-based E.I. du Pont de Nemours and Co.Dehumidifying and Drying Machinery. This early research, headed by W.H. Carothers,Cabinet Dryer, 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,Central Material Handling System. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.Dehumidifying and Drying Machine,European Type Hopper Dryer. 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.Hot Air Dryer, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.HDV Conveyor Integrated Hot Air 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,Hopper Dryer. In this process, ethylene is the polymer, the chemical building block of polyester,Dehumidifying and Drying.
Polyester is manufactured by one of several methods.Manganese Gluconate. The four basic forms are filament,Copper Gluconate, tow, and fiberfill. In the filament form,Zinc Gluconate, producing smooth-Magnesium Gluconate.Potassium Gluconate, filaments are cut to short,Magnesium Lactate.Zinc Lactate. 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.Ferrous Lactate.
Preservatives Blends, 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,Antioxidants Blends. The rope-Curing Agent For Meat.
Carrageenan For Tumbling And Marinated,Aluminium Phosphate's fastest-growing fiber.Zinc Metaphosphate. 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,Diammonium Phosphate, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Zinc Phosphate. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Boron Phosphate, 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.Ammonium Metaphosphate. 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.Sodium Metaphosphate.Specialty Phosphates.
.
the yarn produced is deoffed from the winders checked for the properties and packed in the pallets of 60 spools each.
Potassium Metaphosphate,Dipotassium Phosphate
Potassium Phosphates,it is mainly for sticking filaments together
