Title:
EXCHANGE REACTION SYSTEM, MODIFIED POLYESTER PRODUCTION SYSTEM COMPRISING SAME, MODIFIED POLYESTER PRODUCTION METHOD AND MODIFIED POLYESTER FIBRE PRODUCT
Document Type and Number:
WIPO Patent Application WO/2016/045020
Kind Code:
A1
Abstract:
Provided are an exchange reaction system, a modified polyester production system comprising same, a modified polyester production method and a modified polyester fibre product. The exchange reaction system comprises a vertical complete mixed flow reaction kettle and a vertical plug flow reaction kettle. The vertical complete mixed flow reaction kettle comprises a first material inlet and a first material outlet provided thereon; and the vertical plug flow reaction kettle comprises a second material inlet and a second material outlet provided thereon, wherein the vertical complete mixed flow reaction kettle is provided on the top wall of the vertical plug flow reaction kettle, and the first material outlet is in communication with the second material inlet. The exchange reaction system of such a directly connected structure can allow a material to quickly and conveniently enter the vertical plug flow reaction kettle under the action of gravity such that the exchange reaction conditions are close to a homogeneous phase, which thus improves the distribution uniformity of a modifier in the backbone of polyester molecules, and thereby the obtained modified polyester structure is highly uniform, and the system is suitable for producing high quality fibre and film products.
