Methods and apparatus for making single layer,pseudo-interwoven wet-formed textile fabrics

Abstract

Abstract A FORMAMINOUS, WET-FORMED, SINGLE-LAYER, PSEUDO-INTERWOVEN TEXTILE FABRIC IN THE FORM OF A RANDOMLY INTER MIXED CROSSED LATTICE HAVING A UNITARY STRUCTURE AND BALANCED CONSTRUCTION COMPRISING UNCARDED, RELATIVELY STRAIGHT, SMOOTH-SURFACED, SYNTHETIC TEXTILE FIBERS HAVING AN AVERAGE LENGTH OF FROM ABOUT 3/4 INCH TO ABOUT 11/2 INCHES OR MORE, THE SINGLE-LAYER, PSEUDO-INTERWOVEN TEXTILE FABRIC HAVING TWO MAJOR AXES OF PREDOMINANT FIBER ORIENTATION DIRECTED AT ANGLES TO EACH OTHER, A PREPONDERANCE OF THE FIBERS BEING ARRANGED IN GENERALLY PARALLEL ARRAYS OF BUNDLES WHICH ARE GENERALLY ORIENTED IN THE DIREACTION OF ONE OF THE TWO MAJOR AXES OF PREDOMINANT FIBER ORIENTATION, THE ARRAYS OF BUNDLES BEING PSEUDOINTERWOVEN WITH EACH OTHER IN A SINGLE LAYER, FORMING A RANDOMLY INTERMIXED CROSS LATTICE. ALSO INCLUDED ARE METHODS AND APPARATUS FOR MAKING SUCH FORAMINOUS, WETFORMED, SINGLE-LAYER, PSEUDO-INTERWOVEN TEXTILE FABRICS COMPRISING: FORMING A SUBSTANTIALLY UNIFORM AQUEOUS SLURRY CONTAINING SYNTHETIC FIBERS HAVING AN AVERAGE LENGTH OF FROM ABOUT 3/8 INCH TO ABOUT 11/2 INCHES OR MORE; CAUSING THE AQUEOUS SLURRY OF FIBERS TO FLOW AT A PREDETERMINED VELOCITY IN A THIN, FLAT, SHEET-LIKE, LAMINAR, PLANAR CONFIGURATION; ANGULARLY DEFLECTING THE FLOWING AQUEOUS SLURRY OF FIBERS; ANGULARLY DISCHARGING THE AQUEOUS SLURRY OF FIBERS UPON A MOVING FORMING SURFACE HAVING A PREDETERMINED VELOCITY; AND FORMING THEREON A FORAMINOUS, SINGLE-LAYER, PSEUDO-INTERWOVEN FIBROUS STRUCTURE IN THE FORM OF A RANDOMLY INTERMIXED CROSSED LATTICE.
