The present invention is a method of producing a coating liquid-impregnated reinforcing fiber fabric 1b, including allowing a reinforcing fiber fabric 1a to pass substantially vertically downward through the inside of a coating section 20 storing a coating liquid 2 to provide the reinforcing fiber fabric 1a with the coating liquid 2; wherein the coating section 20 includes a liquid pool and a narrowed section which are in communication with each other; wherein the liquid pool has a portion whose cross-sectional area decreases continuously along a running direction of the reinforcing fiber fabric 1a, wherein the narrowed section has a slit-like cross-section and has a smaller cross-sectional area than the top side of the liquid pool, and wherein the vertical height of the portion whose cross-sectional area decreases continuously in the liquid pool is 10 mm or more.

A web support with a high degree of patterning freedom and excellent durability, a production method therefor, and a patterning method. The web support is used when applying a pattern to a nonwoven substance by jetting a high-pressure water stream on a web. The web support production method comprises: a step of preparing a flat metal base material; a step for forming, by etching, a first water conduction hole and second water conduction hole that pass through the front surface of the base material to the back surface, and a recess on the front surface of the base material that includes the first water conduction hole and that corresponds to the pattern; and a step for forming the base material into a cylindrical main body section by welding the edges of the base material to each other.

A method for the treatment of a textile substrate is described, in which the substrate is arranged in a treatment device and treated with an aqueous treatment bath. Here the moisture of the textile substrate is adjusted to a predetermined moisture in the beginning of the treatment, whereby the treatment bath volume to be sprayed on the respective subject and per time unit is determined exactly, so that the textile subject provides the defined predetermined moisture at the end of the treatment. The therefore used devices enables the realization of the method for textile substrates designed as a fabric strand, a wide fabric web package and a fabric package.

An apparatus and method for applying one or more materials, such as one or more additive materials, to a substrate. The substrate may be a fabric, fiber or yarn but not limited thereto. The apparatus includes an array of a plurality of applicators arranged in proximity to the substrate while the substrate is moving or in a static position. The applicators are arranged to deliver a mixture of one or more materials and a material delivery vehicle to the substrate sufficient to bond at least a portion of the one or more materials into the substrate or adhere the one or more materials to the surface of the substrate. The material delivery vehicle may be air. The applicators include nozzles configured to generate a dispersion pattern that provides substantially uniform and substantially complete coverage of the one or more materials onto and/or in the substrate. The apparatus may include an optional heater to warm the substrate to improve adhesion of the one or more materials on and into the substrate.

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.

Methods are provided for improving the papermaking process. In various embodiments, the methods include the application of alkali material in combination with an anionic polymeric dispersant and/or a hydroxyfunctional carboxylic acid to papermaking fabrics such that the application thereof removes contaminants from the papermaking fabrics and improves the drainage of said papermaking fabrics. Such alkali material in combination with an anionic polymeric dispersant and/or a hydroxyfunctional carboxylic acid can be applied as a single aqueous solution, and may further comprise a surfactant.

A device for applying a foamed treating material under pressure to a traveling sheet of relatively incompressible textile yarns. A foam applicator unit has a nozzle with a foam dispensing slot facing across one side of the traveling sheet of yarns. A drive roll faces the other side of the traveling sheet of yarns in tangential alignment with the foam dispensing slot. The roll has a resiliently compressible, soft rubber outer layer, which compresses to conform with the surface of the relatively incompressible yarns and presses the traveling sheet of yarns against the applicator surfaces leading to and away from the slot to prevent escape of foam and to prevent passage of foam between yarns to maintain uniform distribution of foam applied to the traveling sheet of yarns.
