Described is a composite made from a woven fabric, a non-woven fabric, or a knitted face fabric and a non-woven fabric. The woven fabric, the non-woven fabric, or the knitted face fabric is needle punched such that fibers protrude into the non-woven fabric. The woven fabric, the non-woven fabric, or the knitted face fabric has a first polymer having a first melting point and a second polymer having a second melting point being higher than the first melting point. The nonwoven backing material comprises a third polymer having a third melting point and a fourth polymer having a fourth melting point being higher than the third melting point. The woven fabric, the non-woven fabric, or the knitted face fabric is further bonded to the nonwoven backing material applying heat to at least partially melt or soften the first polymer and the third polymer such that they bond together.

Described herein are methods of preparing continuous polyolefin textiles laminated to a physically crosslinked, closed cell continuous foam sheet. The methods can include extruding a foamable sheet through a nip while simultaneously feeding a polyolefin textile into the nip to laminate the textile to the foamable sheet, irradiating the laminate, and foaming the laminate

A fiber sheet structure includes a knit weave and has a cell-mounting front surface and a back surface, the average pore size of the back surface is smaller than the average pore size of the cell-mounting surface, the knit weave includes doubled yarn bundles made of gelatin fiber bundle and thermoplastic resin fiber bundle, the thickness of the fiber sheet structure is 30 to 5000 m, the number of gelatin fibers constituting the gelatin fiber bundle is 5 to 60, the fineness of the gelatin fiber is 0.5 to 10 dtex, the total number of gelatin fiber bundles and thermoplastic resin fiber bundles in the doubled yarn bundle is 2 to 20, and the ratio of the number of gelatin fiber bundles to thermoplastic resin fiber bundles in the doubled yarn bundle is 5:1 to 1:5.

Composite materials are described herein. An example composite material may comprise a shell fiber layer. The example composite material may comprise a membrane disposed adjacent the shell fiber layer.

A combined carpet is provided. The combined carpet includes an upper carpet body and a lower carpet body. The upper carpet body includes a first layer and a first attaching layer under the first layer; the lower carpet body is configured to be paved between the upper carpet and an object surface, and includes a second attaching layer and a second layer under the second attaching layer. An edge area of the first attaching layer extends beyond the second attaching layer to contact the object surface and does not overlap with the second attaching layer, a main area of the first attaching layer and the second attaching layer body realize a relative rest through a static friction force, to prevent relative movement when the upper and lower carpet bodies are connected, thereby forming a detachable combination between the upper carpet body and the lower carpet body.
