    摘要: A method and device are disclosed for producing 3D fabrics including yarns/tows that remain in pre-tensioned condition. Further, the method and device produce 3D fabrics with features that increase the mechanical performance of produced materials which are highly suited for composite materials and impact injury mitigation applications. The method and device also provide a simple, quick and compact arrangement to produce economically both uniaxial and multiaxial types of 3D fabrics with specific dimensions and shapes in ‘middle-outwards’ manner to reduce production time by half by arranging the set of axial yarns in zigzag fashion between oppositely facing supports. The method and device aid automated production of 3D fabrics and their direct packaging to eliminate contamination of produced 3D fabrics. A 3D fabric produced in this way is also disclosed. The 3D fabric includes yarns/tows that remain in pre-tensioned condition.

    摘要: A method of manufacturing a textured element may include (a) collecting a plurality of filaments upon a textured surface to form a non-woven textile and (b) separating the non-woven textile from the textured surface. Another method of manufacturing a textured element may include depositing a plurality of thermoplastic polymer filaments upon a first surface of a polymer layer to (a) form a non-woven textile and (b) bond the filaments to the polymer layer. A textured surface may then be separated from a second surface of the polymer layer, the second surface being opposite the first surface, and the second surface having a texture from the textured surface.

    摘要: A nonwoven material has a plurality of randomly oriented and bulked crimped filaments, a plurality of point bonds interconnecting said crimped filaments into a fixed, 3-dimensional structure, and either a surface portion of said fixed, 3-dimensional structure having a greater density than an inner portion of said 3-dimensional structure or an external surface of said fixed, 3-dimensional structure being substantially free of any protruding filaments. The nonwoven material is made by: bulking a filament tow, fixing the bulked tow into a 3-dimensional structure, and calendering the 3-dimensional structure.
