摘要： An inflatable tube 1 is inserted into a covering layer 2 formed of a thin rubber pouch which is made of a material which does not permit a solution of an adhesive agent, such as an aqueous solution of latex or a solution of an adhesive agent which contains rubber, used to attach a reinforced layer to the covering layer to pass through said covering layer, and an inorganic lubricant 3 disposed between the tube and the covering layer.

摘要： A process for producing wholly aromatic polyamide fibers by extruding a spinning solution of a wholly aromatic polyamide in an amide solvent into an aqueous coagulating bath containing inorganic salts, said process comprising feeding an aqueous coagulating liquid containing calcium chloride and having an amide solvent concentration of not more than 3% by weight to the vicinity of a spinneret, flowing the coagulating liquid in said bath at an average velocity not more than 0.1 time the velocity of yarn take-up in the yarn advancing direction, discharging the coagulating liquid having an amide solvent concentration of not less than 4% by weight from said bath, treating the coagulating bath with an organic solvent consisting substantially of methylene chloride, and extracting and recovering the amide solvent from the coagulating liquid.
