The present application provides a calender, a floor production line and a production method using the calender, wherein the calender comprises a calendering roller rack and a set of calendering rollers arranged on the calendering roller rack. The set of calendering rollers comprises a plurality of calendering rollers arranged in a line and not vertically. The present application changes the arrangement of the calendering rollers. The calendering rollers are arranged in a line, not vertically. This arrangement reduces the overall height of the calender, decreases the requirements of the calender on the height of the factory building and facilitates long-distance transportation by containers. Using the calender to assemble the floor production line, the height space of the factory building occupied by the production line can be saved.

A making plastic flooring having a backing contains: a body which has a substrate, a printing layer, and an anti-abrasion layer. A method of making the plastic flooring contains steps of: (A). producing a semi-finished plastic flooring, wherein the semi-finished plastic flooring has the substrate, the printing layer, and the anti-abrasion layer; (B). moving and positioning the semi-finished plastic flooring on a predetermined position of drop plastic equipment, wherein the semi-finished plastic flooring is faced upward; (C). molding the backing, wherein the backing material is melt and is spray onto a bottom of the substrate of the semi-finished plastic flooring by using drop plastic equipment, and the backing material is adhered on the bottom of the substrate of the semi-finished plastic flooring after being solidified; and (D). cutting, wherein the semi-finished plastic flooring having the backing is removed and is cut into a desired size, thus producing the body.

A method of manufacturing a building panel, including mixing wood fibre particles and a binder to form a first mix, applying the first mix, while the first mix is in powder form, on a core for forming a sub layer on the core, applying a surface layer on the sub layer, wherein the surface layer comprises a second mix of wood fibre particles and a binder, pressing the core, the surface layer, and the sub layer, under increased pressure and temperature, and forming them into a building panel. A building panel formed by the method.

A breathable and waterproof membrane and a method for manufacturing the same, and a breathable and waterproof fabric are provided. The breathable and waterproof membrane is formed by stretching a polyolefin material. The breathable and waterproof membrane has a density ranging from 0.6 g/cm.sup.3 to 0.8 g/cm.sup.3. A plurality of micropores are formed on the breathable and waterproof membrane, and the plurality of micropores each has a size smaller than 500 nm. The polyolefin material includes: 60 wt % to 80 wt % of a first polypropylene resin, 15 wt % to 30 wt % of a second polypropylene resin, and 1 wt % to 10 wt % of inorganic particles. The second polypropylene resin is a modified polypropylene resin having a hydrophilic group. The second polypropylene resin is different from the first polypropylene resin.

A method of preparing antimicrobial material sheets suitable for manufacturing a wide range of products having antimicrobial properties. In exemplary embodiments, a fabric having antimicrobial agents may be calendered with a polymer such as a silicone compound or an elastomer, in order to create a fused material sheet that contains the antibacterial properties of the fabric. In exemplary embodiments, the antimicrobial agent is copper, a copper alloy, silver, a silver alloy, or other suitable antimicrobial agent from which a fabric may be created. In some exemplary embodiments, an uncured silicone composition and copper alloy fabric are calendered to obtain an antimicrobial material sheet suitable for compression molding a wide range of products. In some exemplary embodiments, an uncured silicone composition and copper alloy fabric are calendered and roto-cured to obtain a cured antimicrobial material sheet or sheet rolls that maybe suitable for die-cutting.

A method for making nonwoven fabric. The nonwoven fabric can include three-dimensional features that define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property. The nonwoven further has a plurality of apertures, wherein at least a portion of the aperture abuts at least one of the first region and the second region of the microzone.

Described herein are resilient floor coverings produced by using digitally printed UV-cured inks and exhibiting high adhesion properties between an ink layer and a wear layer. Also described herein are methods for manufacturing same. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

Gaskets, including aircraft gaskets, are disclosed, the gaskets having an elastomeric gel body and substantially incompressible skeletons. The bodies may be pliable and deformable and, in one example, may be comprised of a two-part chemically cured polyurethane that sets up as a gel after mixing with the web so that it is fully integral with the web and so that there is substantially no air bubbles or air pockets left in the web. The web may be a regular shaped web and made of nylon.
