A composite nonwoven mat and a method of making a composite nonwoven mat are provided. The composite nonwoven mat includes a nonwoven base layer having a first surface and a second surface, and a coating layer formed on, penetrating into, and adhered to the first surface of the nonwoven base layer. The coating layer includes a polymer material and a carrier composition. The composite nonwoven mat has an average Gurley porosity of at least 500 seconds.

The present application provides a fabric coloring method and a colored fabric, where the fabric coloring method includes: performing radiation drying on a base cloth; sequentially forming an adhesive layer and at least one color-generating layer on a surface of the base cloth after the radiation drying by vacuum deposition, where the adhesive layer contains at least one of Ti, Cr, Si and Ni, and a thickness of the adhesive layer ranges from 1 nm to 2000 nm; the color-generating layer contains at least one of Al, Ti, Cu, Fe, Mo, Zn, Ag, Au, and Mg, and the total thickness of the color-generating layer ranges from 1 nm to 4000 nm. The fabric coloring method can not only produce rich colors and make the colored fabric have good color fastness, but also reduce the sensitivity of color of the colored fabric to thickness of the film, thus improving the industrial operability.

A textile includes a substrate and a coating applied to a surface of the substrate. The coating includes a plurality of bilayers positioned one on top of the other. Each bilayer includes a first layer including a cationic polymer and a second layer comprising an anionic polymer.

The anionic polymer in the second layer includes a poly(acrylic acid) (PAA), a poly(styrene sulfonate) (PSS), a poly(methacrylic acid) (PMAA), a poly(sodium phosphate) (PSP), or a poly(vinyl sulfate) (PVS).

A process for coating a fabric web on upper and lower sides in one pass containing unwinding a fabric web, coating the upper side of the fabric web with a upper coating composition using a first coater, coating the lower side of the fabric web with a lower coating composition using a second coater, drying the coated fabric web in a horizontal dryer, and winding up the coated fabric web.

The upper and lower coatings are each in an add-on amount of between about 10 and 75 GSM. The second coater comprises an entry edge and a beveled exit edge, where the entry edge is located closer to the first coater than the beveled exit edge, the entry edge of the second coater is in contact with the lower side of the fabric web, and the beveled exit edge of the second coater is not in contact with the web.

A yarn for reinforcing composite material includes carbon nanotubes. The yarn has also been treated to promote interaction with a resinous matrix.

This disclosure provides a method for preparing a current collector. The method includes: (1) anchoring vinyl groups onto the surface of textiles through the silanization between hydroxyl groups and coupling agents; (2) synthesizing polyelectrolyte brushes through in-situ radical polymerization; and (3) obtaining catalyst ions on the polyelectrolyte brushes through ion-exchange and obtaining metal-coated layers through subsequent electroless deposition). The current collector according to the present disclosure has high electrical conductivity and excellent mechanical flexibility, and thus the lithium ion battery including the same is suitable for portable and wearable electronic devices.

A partially degradable polymeric fiber includes a thermally degradable polymeric core and a coating surrounding at least a portion of the core.
