摘要： A process and apparatus for producing a fibrous assembly. At least one fiber-forming polymer is extruded through a spinneret having numerous small openings. The process uses a die equipped with a spinneret having numerous closely spaced small openings and an opening ratio (.alpha.) of at least 30%. At least one fiber-forming polymer in the form of a shaped mass having a specified compression resistance is continuously stuffed into said die. Said shaped mass has a shape such that it measures more in one direction than in another. There is passed through the spinneret an electric current sufficient to give said fiber-forming polymer Joule heat required for cutting said polymer by partitioning members defining the numerous small openings of the spinneret. The cut fiber-forming polymer is taken up as fine streams.The present invention provides ultrathick aromatic polyamide fibers having an average cross-sectional area of about 0.01 mm.sup.2 to about 5 mm.sup.2 and comprising at least one fiber-forming aromatic polyamide and an inorganic or metallic fine powder or a fibrous material.

摘要： A composite structure is prepared by extruding a molten thermoplastic resin and foaming agent through a die and simultaneously quenching and taking-up the extrudate under such conditions that the extrudate is fibrillated just as it leaves the die exit without passing through the foamed state. The unopened, sheet-formed and reticulated fibrous structures thus obtained are laminated, pulled apart and pressed. The composite product consists of a fine and uniform fibrillar structure having superior mechanical strength and pliability and are useful for a wide range of applications such as paper substitute, artificial wood veneer and the like. Colored products are also described.
