Abstract: Different fluid polymers are continuously discharged into a limited space, at the same time, with passages for the polymers being moved relative to spinning orifices of a spinneret. A multiple layer flow is formed in which the different polymers alternate in the direction of flow. When the multiple layer flow is passed through the orifices of the spinneret plate, cooled and solidified or dried and coagulated, a fiber is obtained in which the different polymers are alternately arranged along the fiber. The interfaces between the different polymers are parabolic curved surfaces.

Abstract: In a method of weaving a three-dimensional article according to the present invention, an area arranging carrier members (1) in the form of a matrix is segmented into a plurality of rectangular blocks (G1 to G6) to choose prescribed blocks therefrom, and then a basic weaving operation is sequentially and alternately performed with respect to the prescribed blocks. According to the weaving method, it is possible to easily weave many kinds of three-dimensional articles (2) having different sectional forms. In an apparatus for weaving a three-dimensional article according to the present invention, first guide means (16) for guiding the movement in row direction of the carrier members (1) and second guide means (17) for guiding the movement in column direction of the carrier members (1) are provided, so that the carrier members (1) are smoothly moved in the row and the column directions by the first and the second guide means (16 and 17).

Abstract: In a method for producing oxidized filaments (102) by treating precursor filaments (101) in a bed (5a) fluidized by an oxidizing gas and heat treating the precursor filaments (101) in the fluidized bed (5a), the fluidized bed (5a) is formed with heat-medium particles (5), not less than 80% by weight of which are of solid particles each having a particle diameter of not greater than 10 mesh, and the oxidation is carried out under optimum conditions within an optimum range of the treatment temperatures, an optimum range of depths H of the fluidized bed (5a) and an optimum gas speed of the oxidizing gas. By the method, the period of time required for the oxidation can be greatly shortened and oxidized filaments (102) having excellent characteristics can be obtained Furthermore, where the oxidized filaments thus obtained are carbonized, carbon fibers having excellent mechanical properties can be produced.

Abstract: Yarn ball-forming containers with curved inner surfaces are moved to be presented in succession to a tubular guide for yarn lengths separated from a supply by a feed system and a cutter mechanism. Air jet nozzles form yarn balls in respective containers, for subsequent removal by an air ejector mechanism connected to a conveyor. The ball-forming containers are specif. perforated, and the air jets which form the balls are heated to yarn-fusing temperatures so that the balls are form-stable. Economic filter balls may thus be obtd. for quilts, cushions, sleeping bags, garments, esp. of wholly or partly synthetic filamentary yarns such as polyesters.
