Nylon 66 Mfg. Process - TEXTILE LIBRARY Manufacturing Process of Nylon 6,6 Nylon 6,6 is made from Hexamethylene diamine and adipic acid as shown in the figure below. Spinning of Nylon 6,6 . The chips of nylon polymer are fed through a hopper A, into a spinning vessel B, on an electrically heated grid ( perforated plate) C. The perforations are so small that the chips do not pass[PDF] An industrial process for the production of nylon 6 6 Mar 03, 2017Section 6: Material Balances and Process flow diagram Figure (6.1): Calculated Mass Balance – Material Requirements lb/year lb/hr nylon 66 production rate 86700000 10997 adipic acid 56488120 7165 hexamethylene diamine 44917761 5697 Figure 6.2: Simulated Mass Balance Simulator Mass Balance Streams mass flow rate (lb/hr) in / out Preparation, Properties and Applications of Nylon 6,6 Nylon-66 production from adipic acid and hexamethylene diamine comprises four steps: (1) Salt preparation (2) Polycondensation (3) Melting.
