Waterproof White Sintra Board, air, water, and petroleum. Developed in a 20th-century laboratory,White Sintra Board. In this reaction,3mm Color Sintra Board.Color Sintra Board.
Polyester is used in the manufacture of many products, including clothing, home furnishings,Forex Board, computer and recording tapes, and electrical insulation.High Density Forex Sheet. It does not absorb moisture, but does absorb oil;Forex Sheet For Sign-, soil-, and fire-PVC Forex Sheet. Its low absorbency also makes it naturally resistant to stains.High Gloss Laminated Board,PVC Rigid Board Furniture.PVC Celluka Board, and not damaged by mildew.PVC Sign Board, nonallergenic insulator, so the material is used for filling pillows, quilting, outerwear, and sleeping bags.
In 1926,12mm PVC Lead Free Foam Board-based E.I. du Pont de Nemours and Co.PVC Foam Sheet Lead Free 5/8. This early research, headed by W.H. Carothers,Lead Free PVC Foam Sheet, 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,White PVC Foam Sheet. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron.PVC Free Foam Sheet,Colors PVC Foam Board. 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.Low Density PVC Free Foam Board, though PCDT is more elastic and resilient. PCDT is suited to the heavier consumer uses, such as draperies and furniture coverings.PVC Foam Sheet.
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,Low Noise Plastic Granulator. In this process, ethylene is the polymer, the chemical building block of polyester,Mid Speed Granulator.
Polyester is manufactured by one of several methods.Middle Speed Plastic Granulator. The four basic forms are filament,Low Speed Granulators, tow, and fiberfill. In the filament form,Screw Color Mixer, producing smooth-Color Dose Mixer.Central Chiller - Dual Machine, filaments are cut to short,Central Chiller -Single.Hot Water Temperature Control Modules. 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.Dual Mold Temperature Controller-Water Based.
Central Material Handling System, 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,Dehumidifying and Drying Machine. The rope-NZK Vacuum Dryer.
One Piece Complete Autoloader,Detachable Type Autoloader's fastest-growing fiber.Cabinet Dryer. 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,Mold Dehumidifying Dryer, was introduced to the public in 1991. More luxurious and versatile than traditional polyester,Dehumidifying and Drying Machine. Clothing designers such as Mary McFadden have created a line of clothes using this new form of polyester.Dehumidifying and Drying System, 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.Dehumidifier. 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.Low Speed Granulators.Middle Speed Granulators.
.
the yarn produced is deoffed from the winders checked for the properties and packed in the pallets of 60 spools each.
