A rigid three-dimensionally shaped fiber network structure having improved post-yield dimensional recovery is provided. The fiber network structure is formed from a fabric containing (A) at least one oriented, semi-crystalline monofilament yarn made from a first thermoplastic polymer, and (B) a second thermoplastic polymer which effects bonding of the monofilament cross-over points. The fiber network structures are useful in a variety of articles, including sandwich panels, various spacers, drainage systems, and energy absorption structures.

A three-dimensionally shaped fiber network structure having both resiliency and improved softness and aesthetic properties is composed of a deformed textile fabric formed from at least one monofilament and at least one multifilament yarn and having a plurality of deformations formed as a two-dimensional array in a base region of the deformed textile fabric. The deformed textile fabric is preferably a knitted or a woven fabric. The network structure is made by forming a deformable fabric from the monofilament and the multifilament yarn and then subjecting the deformable fabric to an area-enlarging deformation process, e.g., a thermomechanical process, to produce the deformed textile fabric having the deformations formed in a base region thereof. The three-dimensional network structures may be used in a variety of articles, including cushioning materials, impact-absorbing materials, and load-bearing materials.

Three dimensional fiber networks which are semi-rigid and dimensionally stable are made from textile fabrics that have projections and optional depressions which are compressible and return to their original shape after being compressed. The fiber networks are made by the thermo-mechanical deformation of textile fabrics that are in turn made from thermoplastic fibers. The fiber networks have particular utility as cushioning and impact absorbing materials.

Shoes for use in demanding applications, primarily athletics, are made from a three-dimensional fiber network that is semi-rigid and resilient. The fiber network is made from a textile fabric that has an array of projections made from the same fabric rising from the plane of the fabric.

Cast padding materials and padding and lining materials for other orthopedic devices are made from three dimensional fiber networks which are semi-rigid and dimensionally stable. The fiber networks are made from textile fabrics that have projections and optional depressions which are compressible and return to their original shape after being compressed. The fiber networks are made by the thermo-mechanical deformation of textile fabrics that are in turn made from thermoplastic fibers.

A rigid three-dimensionally shaped fiber network structure having improved post-yield dimensional recovery is composed of a deformed textile fabric network structure containing: (A) at least one oriented, semi-crystalline monofilament yarn containing a thermoplastic polymer and disposed in the deformed fabric so as to provide a plurality of monofilament cross-over points therein; and (B) a cured crosslinkable resin impregnating the deformed network structure so as to effect bonding of all or substantially all of the monofilament cross-over points. The network structure is made by subjecting the monofilament yarn to a fabric-forming process to form a deformable fabric, subjecting the deformable fabric to an area-enlarging deformation process to form the initial three-dimensionally shaped network structure composed of a deformed textile fabric, demolding the initial network structure and then curing the crosslinkable resin, which has been added before the deformation process, before demolding and/or after demolding. Curing of the crosslinkable resin bonds all or substantially all of the monofilament cross-over points, thereby converting the initial network structure into a rigid final network structure having improved post-yield dimensional recovery.

The invention is a method of producing a melt spun synthetic polymeric filament which has the superior deep dyeability thereof. The method includes the steps of application of a dye dispersed in water to the filaments during the drawing of the filament, and heat setting the surface dyed filaments to uniformly diffuse the dye throughout the total cross section of the filaments.
