Air-sealed body capable of automatically opening air valve
09724902 · 2017-08-08 · ·

An air-sealed body capable of automatically opening an air valve is provided. First, the two inner films are laminated between two outer films. An air passage and a plurality of air columns are formed through joining by means of heat-sealing. Air inlets are formed by heat-sealing in the two inner films at the places where the heat-resisting material is coated, and a plurality of heat-sealed blocks are formed through joining by means of heat-sealing at the sides of the air inlets. When air is filled in, the two outer films of the air passage are pulled open outward in a longitudinal direction, the air passage contracts in a lateral direction due to a drop height of the heat-sealed blocks. The two inner films are squeezed by the heat-sealed blocks to be pulled open outward in the longitudinal direction to open the air inlet.

20220184925 · 2022-06-16 ·

This invention relates to a functional textile manufacturing system. This system uses weaving equipment, dyeing and finishing equipment, shaping equipment, evaporation equipment, lamination equipment, roll adhesion equipment and printing equipment for production. Weaving equipment, dyeing and finishing equipment and shaping equipment are used for weaving, dyeing, washing and shaping to process low-cost polyester fibers into shaped fabric. Then, the evaporation equipment is used to evaporate a metal onto a plane release film to form a metal evaporation release film, and the lamination equipment, roll adhesion equipment and printing equipment are used to laminate the shaped fabric and the metal evaporation release film and to adhere a printed layer on the functional thin film. Such a manufacturing system can produce laundry resistant unconventional material antimicrobial protective fabric that features special temperature control, antimicrobial, waterproof, breathable, scratch resistant properties, as well as comfortable feeling.

ULTRAFAST WATER FLUX THROUGH HOT-PRESSED SOLUTION BLOWN SPUN NANOFIBER-BASED THIN FILM COMPOSITE MEMBRANES FOR FORWARD OSMOSIS

Described herein are polysulfone-based and polyether sulfone-based thin-film nanocomposite (TFNC) membranes produced by solution blow spinning (SBS) technology for forward osmosis applications, including desalination and wastewater treatment. These TFNC membranes exhibit ultra-fast water flux, low reverse salt flux, and fouling resistance.

Wear-resistant coating film, wear-resistant member, method for producing wear-resistant coating film, and sliding mechanism

A wear-resistant coating film is disclosed that can maintain high wear resistance for a long period of time even when it is subjected to repetitive wear, and a method for producing the film, as well as a wear-resistant component. The wear-resistant coating film 10 includes a plated layer 11, lump parts 2, and a coat layer 13. The plated layer and the coat layer are laminated, and each of the lump parts is formed of a single particle 12 and/or an assembly of particles 12. The lump parts 2 are held by the plated layer 11 and are disposed to protrude from the plated layer 11. The coat layer 13 is formed to coat the surface of the plated layer 11, the lump parts 2 have flat portions 18, and the flat portions 18 are placed on the same plane as the surface of the coat layer 13.

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.

BUNDLING OF SINGLE-USE PLASTICS INTO REUSABLE MATERIAL

Methods and apparatus are disclosed for bundling of single-use plastics into reusable material. An example method for forming a sheet of insulation includes arranging a plurality of single-use plastic straws to be parallel to each other in a side-by-side manner. At least some of the plurality of single-use plastic straws are arranged to contact adjacent ones of the plurality of single-use plastic straws. The example method also includes applying fastening material to the plurality of single-use plastic straws to couple the plurality of single-use plastic straws together.

Method and apparatus for roll-to-roll processing of sheet stock
11220127 · 2022-01-11 · ·

A method of processing sheet stock in the creation of plastic cards, such as gift cards or credit cards that include special effects and/or security measures. A card formed by such methods is also disclosed. The method provides for two or more dissimilar materials to be bonded together while maintaining the integrity of the card and as any graphics, security features, and/or special effects provided thereon. Thermoset and thermobond adhesive layers are placed between a first material layer and a second material layer of the sheet stock. The thermoset and thermobond adhesive layers allow the first and second material layers to move independently and to expand and contract at different rates relative to each other. The adhesive layers enable the sheet stock to be rolled up for shipping or storage and further enable the end product produced therefrom to have a planar profile.
