Apparatus and method for spray treating fabric
11472213 · 2022-10-18 · ·

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.

Web support, production method therefor, and patterning method

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.

Method for dyeing and removing colored impurities

APPAREL WITH DYNAMIC VENT STRUCTURE

Aspects herein are directed to an article of apparel having a vent opening formed by overlapping the edges of a first panel and a second panel. A plurality of discrete overlay film structures are applied to the second panel adjacent to the vent opening. When the article of apparel is exposed to an external stimulus, the film structures undergo a reversible increase in dimension in at least the z-direction which cause the second panel of material to undergo a reversible decrease in dimension in the direction of a longitudinal axis of the vent opening thereby causing the vent opening to dynamically transition from a closed state to an open state.

20230103871 · 2023-04-06 · ·

The present invention relates to a method for manufacturing insulation products based on mineral wool bound by an organic binder, comprising the following successive steps: (a) providing a mineral wool, (b) humidifying the mineral wool, (c) placing the humidified mineral wool fibers in contact with particles of binder comprising a mixture of thermosetting reagents, (d) shaping the mixture of mineral wool and binder particles, and (e) heating the shaped mixture to a temperature and for a period sufficient to allow the condensation of the reagents and the formation of an insulation product based on mineral wool bound by an insoluble and infusible organic binder.

SYSTEMS AND METHODS FOR THE FUNCTIONALIZATION OF POLYOLEFIN FIBERS

A system for the functionalization of polyolefin fiber includes a reactor chamber, a fiber pulley system, and a precursor sprinkler system. The reactor chamber defines an interior reactor space and a plurality of fiber inlet/outlet pairs positioned at opposite ends of respective fiber processing axes. The fiber pulley system is arranged to direct polyolefin fiber through the plurality of fiber inlet/outlet pairs, along a fiber processing path comprising the respective fiber processing axes. The precursor sprinkler system is operable to aerosolize a precursor solution and contact the aerosolized precursor solution with the polyolefin fiber. A method for functionalizing polyolefin fiber includes aerosolizing the precursor solution to form an aerosolized precursor solution, passing polyolefin fiber along the fiber pulley system into the reactor chamber, contacting the polyolefin fiber with the aerosolized precursor solution, and passing functionalized polyolefin fiber out of the interior reactor space of the reactor chamber.
