ANTIMICROBIAL SUBSTRATES
20230240289 · 2023-08-03 · ·

A method for forming an antimicrobial coating on a substrate is provided. The method comprises dissipating and entrapping (embedding) sulfonated copolymer particles in void spaces or interstices of fibers of a fabric forming an outer layer of a substrate. The sulfonated copolymer is selected from the group of perfluorosulfonic acid polymers such as sulfonated tetrafluoroethylene, polystyrene sulfonates, sulfonated block copolymers, polysulfones such as polyether sulfone, polyketones such as polyether ketone, sulfonated poly(arylene ether), and mixtures thereof. The fibers comprise a thermoplastic polymer having a melting point of less than 120° C., or 45-110° C., or 45-80° C. The sulfonated copolymer forms an antimicrobial coating layer for killing at least 90% microbes in the air within 30 minutes of contact with the coating.

LOW WEIGHT MODULAR CARPET COMPONENTS AND METHODS OF MAKING THE SAME
20230243094 · 2023-08-03 ·

A low-weight carpet tile and process for making the same, wherein the carpet tile comprises a facecloth having a plurality of face yarns tufted through a primary backing, an extruded polymer secondary backing layer, and a reinforcing scrim layer partially un embedded within the extruded polymer secondary backing layer. The top surface and bottom surface of the carpet tile are defined by the facecloth and the reinforcing scrim layer, respectively. A polymer-based resin is extruded onto the facecloth to form an at least substantially uniform secondary backing layer, and the reinforcing scrim layer is laid onto the extruded polymer secondary backing layer while the extruded polymer secondary backing layer remains above a softening temperature for the resin. The entire multi-layer web is then passed through a nip to embed the reinforcing scrim layer into the extruded polymer secondary layer, and the entire web is chilled.

Cleaner with hot plate for floors provided with a sandwich panel for heating and gradual releasing of the water to an underlying cleaning cloth

Hot plate cleaner for floors including a handgrip, a handle, a tank for water, a main body shaped as a brush, a heating plate below the brush and a thermostat, and cleaning fabrics for the floor hooked below a sealing frame, adapted to be hooked and unhooked below the brush, with the interposition of a sandwich panel maintained in contact with the heating plate having a layer of polyurethane foam, placed between two polyester fabrics, and a waterproof element applied to the panel to let the water flow from the tank scatter on the sandwich panel to dampen it so to act as a tank in order to reach the same temperature as the heating plate and keep it unchanged until the panel dries and transmit the same temperature to the cleaning fabric.

CONTINUOUS POLYESTER FIBER TEXTILE CLOTH, PROCESSING EQUIPMENT AND METHOD
20230304214 · 2023-09-28 ·

The invention discloses a continuous polyester fiber textile cloth that can be torn into pieces, processing equipment and a processing method. By ultrasonic hot-melting technology, the polyester fiber textile cloth is subjected to the high temperature generated by the high frequency generated by the action of a metal knife mold and an ultrasonic welding head, so that the thread of the loop layers and the base layer are melted in a line to form a thin line melting body that can be torn apart. The knife mold and the ultrasonic welding head are close to each other and resonate to generate heat. When they leave each other, the resonance disappears and the heat decreases, so as to realize the formation and temperature control of a linear high temperature zone.

Fibrous structures comprising regions having different micro-CT intensive property values and associated transition slopes

Fibrous structures containing solid additives, and more particularly, fibrous structures containing two regions that exhibit at least one common micro-CT intensive property that differs in value and wherein the common micro-CT intensive property transitions between the two regions and methods for making same are provided.

Fibrous structures comprising three or more regions

Fibrous structures containing filaments and solid additives, and more particularly to fibrous structures containing filaments and solid additives wherein the fibrous structure has three or more regions that exhibit different characteristics and/or properties and methods for making same, are provided.

Cleaning article having multi-layer gather strip element

A cleaning article. The cleaning article has a laminate construction. The cleaning article comprises a sheet and a hydrophilic gather strip element joined together at an elongate bond. The gather strip element has plural layers folded upon one another, providing strips extending outwardly from the bond. The folded layers provide a construction which allows the strips to advantageously present a dynamically changing area to the target surface during cleaning, under normal usage conditions. By changing the surface area, more liquids, and associated debris, can be cleaned from the target surface.

Floor cleaning article having strips with differential bond pattern

A cleaning article. The cleaning article has a laminate construction. The cleaning article comprises a sheet and a hydrophilic gather strip element joined together at plural bonds. The gather strip element has plural layers superimposed upon one another, providing strips extending outwardly from the bonds. Different layers are differentially bonded, to provide a construction which allows the strips to advantageously present a dynamically changing area to the target surface during cleaning, under normal usage conditions. By changing the surface area, more liquids, and associated debris, can be cleaned from the target surface.
