Patent number: 6751830Abstract: An apparatus and method for hydroenhancing fabrics is described. The method uses the force of pressurized liquid passing through elongated orifices and impinging on the fabric. The pressurized liquid exits in a coherent or columnar fashion from elongated orifices that are generally rectangular or linear in shape. The elongated orifices can be arranged so as to produce various effects on a web of fabric, including striping, graduated shading and seer-suckering. The elongated orifices also facilitate the hydroenhancement of high-warp-count fabrics without streak or moire effects. Liquid filtration can be relaxed without clogging the orifices, because the elongated orifices permit larger solid objects to pass. The use of elongated orifices also enhances the energy efficiency of the hydroenhancement process.Type: GrantFiled: November 12, 2003Date of Patent: June 22, 2004Assignee: Textile Enhancements International, Inc.Inventors: Herschel Sternlieb, Paul F.

Patent number: 6557223Abstract: 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.Type: GrantFiled: February 15, 2002Date of Patent: May 6, 2003Assignee: Polymer Group, Inc.Inventors: J.

Publication number: 20020121009Abstract: 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. For example, a low energy per pass of {fraction (1/10)} to {fraction (1/48)} the total energy delivered in 10 passes or more can obtain good enhancement results as compared to conventional hydroenhancing at higher total energy levels delivered in fewer passes. 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.Type: ApplicationFiled: February 15, 2002Publication date: September 5, 2002Inventors: J.

Patent number: 5843557Abstract: A structural reinforcement substrate with a conformable batt of relatively long staple oriented structural fibers disposed between at least two layers of randomly oriented short staple fibers and method of production thereof provides a strong, cohesive product which can readily be handled upon subsequent molding yet is readily conformable. Preferably, long oriented structural fibers are used in a plurality of planar elements. The jet orifices are widely spaced to minimize hydro-entanglement such that the original planar relationships of the fibers are substantially maintained.Type: GrantFiled: February 14, 1994Date of Patent: December 1, 1998Inventor: Herschel Sternlieb

Patent number: 5806155Abstract: 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.Type: GrantFiled: June 7, 1995Date of Patent: September 15, 1998Assignee: International Paper CompanyInventors: Frank E.

Patent number: 5737813Abstract: 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.Type: GrantFiled: February 24, 1997Date of Patent: April 14, 1998Assignee: International Paper CompanyInventors: Herschel Sternlieb, Frank E.

Patent number: 5632072Abstract: An hydropatterning apparatus conveys a sheet of fabric through a patterning station along a machine direction on a conveyor, preferably a drum, having a support surface formed with a pattern of raised or solid areas and lowered or void areas, and has one or more manifolds of hydrojet nozzles disposed above the conveyor for directing a continuous curtain of fluid downwardly to impact on the fabric so that properties of the fabric become altered in correspondence to the pattern of the support surface. The hydropatterning technique is used to emboss the screen pattern into the nap of napped fabric in order to produce aesthetically pleasing surface textures and patterns in the napped fabric, such as a fur-like surface texture. The technique can also be used for displacement of yarn or fiber to obtain three-dimensional effects such as ribbing, wavy lines, checkering, geometric or floral designs, or lacework.Type: GrantFiled: January 5, 1995Date of Patent: May 27, 1997Assignee: International Paper CompanyInventors: Arlene T.

Generally, the whitening agent is present in an amount between about 2.5-4% by weight of the fiber, and the whitening agent and light blocking substance are present in a ratio of between about 1000:1 and 800:1. Preferably, the whitening agent is TiO.sub.2 and the light blocking substance is carbon black.Type: GrantFiled: November 19, 1993Date of Patent: November 1, 1994Assignee: Charles Samelson Co.Inventor: Herschel Sternlieb

Patent number: RE40362Abstract: 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.Type: GrantFiled: April 14, 1989Date of Patent: June 10, 2008Assignee: Polymer Group, Inc.Inventors: Herschel Sternlieb, Jodie M.
