A spray applicator (1) for spraying a fluid onto a web (W) of material has a first group of spray nozzles (10A) arranged along a first axis (FA) and a second group of spray nozzles (11A) arranged along a second axis (SA). The first (FA) and second (SA) spray nozzle axes are arranged on the same side of a plane in which the web (W) is run. Each spray nozzle (10A, 11A) has an elongated spray opening configured to spray fluid in a direction towards the web (W). The first spray nozzle opening of the first group of spray ozzles (10A) has an inclination angle which differs from the second nozzle opening inclination angle of the second group of spray nozzles (11A).

A spray coating apparatus is provided, wherein a nozzle is arranged to traverse a fabric in one direction whilst simultaneously spraying and oscillating in another direction. The fabric is spray coated with a first pass having a spray zone having uneven distribution in the direction of oscillation, and particularly with a greater density of fluid coverage toward the centre of the spray zone than an edge. The nozzle forming a second and subsequent pass that is off-set from the first and each subsequent pass respectively. The second and each subsequent pass being arranged to overlap with a portion of the previous pass, thereby providing an improved distribution of the spray coating. Moreover, because the spray coating is incremental, the method is easily adaptable to integrate with an ink jet printing process.

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.

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 method of digitally controlled application and fixation of dyestuff to a textile on a processing line is provided. The method comprising the steps of: determining one or more parameters of a textile; determining, by a processor, at least one dose setting for an array of flow channel dispensers of the processing line, wherein determining the at least one dose setting is based on the one or more parameters; dispensing, by the array of flow channel dispensers, dyestuff onto the textile according to the at least one dose setting and delivering energy to the substrate to fix the dyestuff in the textile.

A system for treating a substrate comprising a treatment module and a substrate plane. The substrate extending along a substrate plane to treat the substrate and wherein a fluid is deliverable via the module to a local region between the module and the substrate plane to treat the substrate with a predetermined treatment.

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.
