Polyester Manufacturing Process

Feb 9, 2014 |

Polyester Manufacturing Process Fibre Manufacturing Process: Today over 70 to 75% of polyester is produced by CP( continuous polymerisation) process using PTA(purified Terephthalic Acid) and MEG. The old process is called Batch process using DMT( Dimethy Terephthalate) and MEG( Mono Ethylene Glycol). Catalysts like 5b3O3 (ANTIMONY TRIOXIDE) are used to start and control the reaction. […more]

Quality Control in Rayon Manufacturing

Feb 9, 2014 |

Quality Control in Rayon Manufacturing As with most chemically oriented processes, quality control is crucial to the successful manufacture of rayon. Chemical make-up, timing and temperature are essential factors that must be monitored and controlled in order to produce the desired result. The percentages of the various fibers used in a blended fabric must be […more]

Polyester Fiber Specification and Properties

Feb 9, 2014 |

Polyester Fiber Specification and Properties Fiber Specification Denier Usually the actual denier is a little on the finer side i.e for 1.2 D, it will be 1.16 and for 1.4 , it could be 1.35. The tolerance normally is +- 0.05 and C.V% of denier should be 4 to 5%. Denier specifies the fineness of […more]

The Spinneret Methods of Spinning Manmade Fibers

Feb 9, 2014 |

The Spinneret Methods of Spinning Manmade Fibers The Spinneret The spinnerets used in the production of most manufactured fibers are similar, in principle, to a bathroom shower head. A spinneret may have from one to several hundred holes. The tiny openings are very sensitive to impurities and corrosion. The liquid feeding them must be carefully […more]

About Manmade Fibers Manufacturing Process

Feb 9, 2014 |

About Manmade Fibers Manufacturing Process Glossary of Various Synthetic Fibers Most synthetic manufactured fibers are created by “extrusion” – forcing a thick, viscous liquid (about the consistency of cold honey) through the tiny holes of a device called a spinneret to form continuous filaments of semi-solid polymer. In their initial state, the fiber-forming polymers are […more]
