Improvements in Hydroenhancement efficiency are obtained by operating a manifold in relative movement to fabric transported under the manifold so as to deliver a low energy to the fabric per pass in multiple passes on the fabric. This results in greater enhancement efficiency and reduction in wasted energy, and also improves fabric coverage and reduces fabric shrinkage. The low-energy per pass, multiple-pass approach can be implemented with improved hydroenhancing equipment of reduced equipment size and cost which simulate multiple passes on the fabric. Embodiments employ a manifold or manifold system that is reciprocated, oscillated, or rotated to simulate multiple passes on the fabric. Other variations for improving hydroenhancement include angling the manifold at a diagonal to the fabric travel direction, using a high density number of double rows of jets to eliminate interference patterns.

Fabric hydroenhancement method & equipment for improved efficiency

Improvements in hydroenhancement efficiency are obtained by operating a manifold in relative movement to fabric transported under the manifold so as to deliver a low energy to the fabric per pass in multiple passes on the fabric. This results in greater enhancement efficiency and reduction in wasted energy, and also improves fabric coverage and reduces fabric shrinkage. The low-energy-per-pass, multiple-pass approach can be implemented with improved hydroenhancing equipment of reduced equipment size and cost which simulate multiple passes on the fabric. In one embodiment, a jigging hydroenhancing equipment transports the fabric back and forth under a stationary manifold between a pair of unwind/windup reels to simulate multiple passes on the fabric. Other embodiments employ a manifold or manifold system that is reciprocated, oscillated, or rotated to simulate multiple passes on the fabric. Other variations for improving hydroenhancement are disclosed.

Fabric hydroenhancement method and equipment for improved efficiency

A suede-like micro-fibril finish is imparted to fibrillatable cellulosic materials by open width hydraulic treatment. Additional enhancement of the fabric finish is obtained by post hydraulic enzyme and wet processing treatments. Fluid treated fabrics of the invention are characterized by substantially uniform fibrillation of fibers within the fabric body and surface areas.

An hydraulic treatment apparatus (10) and method is provided for finishing and upgrading the quality of continuous filament cloth materials. The fabric (12) is supported on a member 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.

Apparatus and method for hydraulic finishing of continuous filament

Striped patterning of dyed fabric, particularly dyed denim, is obtained by impacting the fabric with a row of columnar jet streams of fluid generated from a manifold under pressure while conveying it on a support member in a machine direction through a patterning station. The orifice gauge and diameter, manifold pressure, and line speed are selected to obtain optimal striping without blurring, loss of fabric strength or durability, or excessive warp shrinkage. Preferably, the jet strip is removably interchangeable in a common hydrojet manifold for forming different kinds of striped patterns. The back side of denim fabric may be subjected to pre-treatment to cause the surface of the dyed warp side to fill in and darken with color. A strie striping effect can also be obtained using a combination of jet strips. The striped patterning station can be incorporated at any suitable point in a conventional denim finishing range.

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.
