Abstract:
An apparatus (10) and related process for enhancement of woven and knit fabrics through use of dynamic fluids which entangle and bloom fabric yarns. A two stage enhancement process is employed in which top and bottom sides of the fabric are respectively supported on members (22, 34) and impacted with a fluid curtain including high pressure jet streams. Controlled process energies and use of support members (22, 34) having open areas (26, 36) which are aligned in offset relation to the process line produces fabrics having a uniform finish and improved characteristics including, edge fray, drape, stability, abrasion resistance, fabric weight and thickness.
Abstract:
An hydraulic treatment apparatus (10) and method is provided for finishing and upgrading the quality of filament cloth materials. The fabric (12) is supported on a member (52, 54) and impacted with a uniform, high density jet, fluid curtain (34, 70) under controlled process energies. Low pressure/low energy treatments spread filaments in the fabric to reduce air porosity and provide improved uniformity in material finish. High pressure and energy treatments increase fabric bulk and porosity. Fluid treated fabrics of the invention demonstrate substantial improvement in at least two of uniformity, cover, opacity, increased or decreased bulk, increased or decreased air permeability, abrasion resistance, tensile strength, edge fray, and seam slippage.
Abstract:
A suede-like micro-fibril finish is imparted to fibrillatable cellulosic materials by open width hydraulic treatment, such as with a hydraulic apparatus line (10). The production line includes pre-treatment stations for the fabric (12), such as roll feed table (46), unwind station (14), scray (16), edge guide (18), saturator (20), washer or scouring stations (22, 24) and pre-tenter station (26). Following the pre-treatment, the fabric is advanced through hydraulic treatment modules (30, 32) which include fluid curtain (34), columnar fluid jets (35), endless conveyor (48) driven by rollers (50), planar support members (52, 54) and spaced manifolds (56). The fabric is then advanced to post-treatment stations which include weft straighteners (40, 42), padder station (36), vacuum extractor station (44), frame dryer (38), inspection stations (72, 74), fabric accumulator (76), operator inspection station (78), and fabric wind-up station (80).

Abstract:
Appareil (10) et procédé associé d'amélioration de tissus tissés et à mailles par l'emploi de fluides dynamiques qui enchevètrent les fils et leur donnent un aspect velouté brillant. On utilise un procédé d'amélioration à deux étapes dans lequel les faces supérieure et inférieure du tissu sont respectivement supportées sur des organes (22, 34) et subissent l'impact d'un rideau de fluide comprenant des jets à haute pression. Les énergies commandées du procédé ainsi que l'emploi d'organes de support (22, 34) dotés de zones ouvertes (26, 36) alignées de manière décallée par rapport à la ligne de traitement permettent d'obtenir des tissus présentant un finissage uniforme ainsi que des caractéristiques améliorées parmi lesquelles un effilochage de bordure, un drapé, une stabilité, une résistance à l'abrasion, un poids et une épaisseur de tissu.

Abstract:
A hydropatterning apparatus and method conveys a sheet of fabric (12) through a patterning station (16) along a machine direction on a conveyor (24), preferably a drum, having a support surface (16, 60) formed with a pattern of raised or solid areas (16a) and lowered or void areas (16b), and has one or more manifolds (30) of hydrojet nozzles (32) disposed above the conveyor for directing a continuous curtain of fluid (40) downwardly to impact on the fabric so that properties of the fabric become altered in correspondence to the pattern of the support surface (16, 60). Fabric colored with a non-colorfast dye is hydropatterned by subtractive color removal to obtain a patterned washout effect. Alternatively, a support surface having raised or embossed areas is used to obtain a fiber displacement, lace-like effect in light fabrics. The disclosed hydropatterning technique is particularly suitable for producing a color washout effect in indigo dyed denim.
