Abstract: PROBLEM TO BE SOLVED: To provide a continuous processing method and an apparatus for a thermoplastic material to obtain a high-quality thermoplastic material by preventing funnel flow and enabling fluidized mass flow when a thermoplastic material is continuously supplied and processed with a gas. SOLUTION: An apparatus has a funnel-shaped part 2 occupying at least 10% of the capacity of a processing tower under the processing tower 1, a thermoplastic material inlet 3 and a gas exit 8 on the top of the processing tower 1, a thermoplastic material exit 4 at the bottom of the funnel-shaped part 2 and gas supplying inlets 6a and 7a on the side wall of the funnel part which have open ends inside of the side wall. In this case, a thermoplastic material and a gas for processing are continuously supplied from the thermoplastic material inlet 3 and gas supplying inlets 6a and 7a, respectively. The thermoplastic material is continuously processed by subjecting the thermoplastic material and the gas to a counter-flow contact.

Abstract: PURPOSE:To obtain a polyamide monofilament having high transparency, roundness and strength even in a thick-denier state by melt-spinning a copolymer of epsilon-caprolactam and hexamethylene adipamide together with a multicomponent copolymerized polyamide and a specific bisstearylamide. CONSTITUTION:The polyamide monofilament having high transparency, roundness and strength even in a thick-denier state is produced by melt-spinning (A) 98-80 pts.wt. of a 6/66 copolymerized polyamide produced by copolymerizing 98-70wt.% of epsilon-caprolactam and 2-30wt.% of hexamethylene adipamide, (B) 2-20 pts.wt. of a >=3-component copolymerized polyamide produced by copolymerizing >=3 kinds of polyamide-forming components containing a salt of an alicyclic diamine such as hexahydro-m-xylylenediamine or (p- aminocyclohexyl)methane and a carboxylic acid as essential component and (C) 0.1-1.0 pt.wt. of ethylene-bisstearylamide.

SOLUTION: An apparatus has a thermoplastic material inlet 3 and a gas exit 8 on the top of a processing tower 1, a thermoplastic material exit 4 at the bottom of the processing tower, gas supplying inlets 6a and 7a on the side wall of the lower part of the processing tower 1 which have open ends inside of the side wall and a separating boards 9 facing the gas supplying inlets 6a and 7a which boards have downward open-ends. In this case, a thermoplastic material and a gas for processing are continuously supplied from the thermoplastic material inlet 3 and gas supplying inlets 6a and 7a, respectively. The thermoplastic material is continuously processed by subjecting the thermoplastic material and the gas to a counter-flow contact.

Abstract: PROBLEM TO BE SOLVED: To provide an apparatus adapted so that the abnormal residence of chips and the liquid mixing of extracting water may be satisfactorily prevented, and the discharge of polyamide chips in the form of a mass flow may be made possible without using any inserts such as a flow adjustment spacer and a process for continuously extracting high-quality polyamide chips containing a very small amount of a residual low-molecular-weight substance by using this apparatus. SOLUTION: This invention provides an apparatus for continuously extracting polyamide chips, having a polyamide chip feed port 4 and an extract discharge port 7 on the top of an extraction tower and having a polyamide chip discharge port 5 and an extract feed port 6 at the bottom of the tower and a process for continuously extracting a low-molecular-weight substance from polyamide chips, comprising using the above apparatus in which the lower part of the body of the extraction tower takes the form of an inverse cone.
