Electret webs include a thermoplastic resin and a charge-enhancing additive. The charge-enhancing additive is a divalent metal-containing substituted-mercaptobenzimidazolate salt. The electret webs may be a non-woven fibrous web or a film. The electret webs are suitable for use as filter media.

A fabric, such as a loop fastener material, is finished by applying a foam to a surface of the fabric, the foam containing both a liquid binder and a powder. The binder is allowed to flow into pores of the fabric and coat fiber interstices of the fabric as the foam collapses, and is dried to stabilize the fabric. The powder is of a particle size selected to cause most of the powder to remain on the surface of the fabric while the binder is dried to bond the powder to the fabric surface. The powder, as bonded to the fabric surface, is activatable, such as by heat or RF or UV energy, to adhere the stabilized fabric to another surface or to provide a desired surface property.

A dyeing and finishing method for linen cotton textile fabric with high-shrinkage is described in the present invention, comprises the steps as below: preprocessing, pickling, dyeing and shaping, which can make the fabric with sufficient shrinkage and provide a qualitative sense of linen cotton. Through the above way, in the dyeing and finishing method for linen cotton textile fabric with high-shrinkage provided by the present invention, washing treatment on the fabric by the preprocessing and the pickling before dyeing makes the colorizing more easy and decreases the color difference and colored spot after dyeing, opening the fiber of the fabric and cooling shrinkage during the dyeing process can obtain the unique product style, with a handle more like the linen cotton effect, and a pellet feeling appeared on the cloth cover and the product fabric more like the woven fabric.

A rinsing station for removing residual materials from a fabric being dyed or bleached. The rinsing station includes a first pair of rinse spray nozzles. One of the first pair directed to spray a rinse fluid downwardly onto incoming dyed fabric. The other of the first pair directed to spray the rinse fluid upwardly onto the incoming dyed fabric. The rinsing station also includes a pair of nip rollers downstream for the first pair of rinse spray nozzles for extracting the rinse fluid.

Methods are directed to the use of a supercritical fluid for performing a dyeing of a material such that dye from a first material is used to dye a second material. A supercritical fluid is passed through a first material in a pressurized vessel. The supercritical fluid transports the dye from the first material to at least a second material causing a dye profile of the second material to change as a result of dye from the first material perfusing the second material.

To provide a method of producing a processed cloth capable of forming various concave-convex patterns on a cloth material in a simple manner. A method of producing a processed cloth comprising the steps of: preparing a cloth; printing a first sizing agent containing a foaming agent on at least a portion of the cloth material; and pressing the printed cloth with a heated metal plate to foam the foaming agent. The method of producing a processed cloth may further include a step of printing a second sizing agent containing a coloring agent on the cloth material. The method of producing the processed cloth may further include a step of sublimation transfer to the cloth material.

Systems and methods are described whereby a deoxygenated liquid dye material is made by supplying the deoxygenated inert gas to a liquid dye material that is susceptible to oxidation, and mixing the liquid dye material in the presence of the supplied deoxygenated inert gas with water and at least one dye formulation component selected from the group consisting of reducing agents, pH adjusters, foaming agents, wetting agents and auxiliary chemicals to form a deoxygenated aqueous dye composition having an oxygen content of 30 ppm oxygen or less. A supply of inert gas may be provided which is then passed to a gas purifier to reduce oxygen content in the inert gas to, e.g., 1 ppb oxygen or less. The deoxygenated aqueous dye composition that is formed may have an oxygen content of 1 ppm or less.

Nonwovens having low-density and resilience have a chemical formulation applied on one surface (e.g., a top surface) by any of various application methods. Then, the chemical formulation is forced to move toward the opposite surface of the nonwoven (e.g., move downward through the nonwoven from top to bottom). The chemical-treated nonwoven is dried to fix the chemical on the nonwovens. Movement through the nonwoven is performed in a controlled fashion so that after drying the distribution of a chemical formulation throughout the nonwoven (e.g., from the top surface to the bottom surface of a nonwoven) is controlled.

A color-changing product includes a fabric. The fabric includes a first layer and a second layer. The first layer is arranged using at least one fiber. The at least one fiber includes (a) an electrically conductive core and (b) a coating disposed around and along the electrically conductive core. The second layer is printed onto the first layer. The second layer includes a foreground thermochromic pigment that is selectively activatable by providing an electrical current to the electrically conductive core of the at least one fiber to change at least one of a foreground color or a pattern of the second layer.
