A method of manufacturing a wet-laid nonwoven web includes the following steps: feeding a pulp suspension onto a forming screen for depositing a fibrous web thereon, wherein the pulp suspension has industrially produced, inorganic fibers or fibers of synthetically produced polymers and the pulp suspension is substantially free from binders, such as chemical binders, and hydraulic consolidation of the fibrous web to generate the nonwoven web through water jet needling of the fibrous web.

The present invention addresses the problem of providing: a polishing pad that is long-lasting, has a high polish rate, and is capable of producing a high degree of flatness on polished articles; and a method for manufacturing the polishing pad. The solution provided is to eliminate a sea component from a non-woven fabric that includes a binder fabric and a sea-island type composite fiber composed of the sea component and an island component, the island component having a diameter of 10-2500 nm, and to add a polymer elastic body to the non-woven fabric.

An interior trim part made by a method that includes the steps of bringing a fiber web onto a conveyor, needlepunching the fiber web to form a base in contact with the conveyor, and introducing a binder component on the base. The binder component introduced on the base is a thermoplastic polymer in solid form. The method includes a step for heating the base to cause the thermoplastic polymer making up the binder component to penetrate the base over a thickness smaller than the thickness of the base.

A wet sheet for cleaning includes multiple layers and is impregnated with a chemical solution. The wet sheet includes hydrophobic fiber layers arranged in a front surface layer and a back surface layer, and a hydrophilic fiber layer arranged in an intermediate layer. The hydrophobic fiber layers have an interlaced part with a high fiber density where the hydrophobic fiber layers are interlaced with the hydrophilic fiber layer. The interlaced part has at least one slightly interlaced part and at least one highly interlaced part which is formed in a dent shape and which is interlaced with a higher fiber density. The highly interlaced part is formed in an area ratio of 10 to 20% to an area of the front surface layer or the back surface layer. Static friction resistance of the wet sheet for cleaning is lower than kinetic friction resistance of the wet sheet for cleaning.

Textiles are re-cycled by grinding and scatter-laying onto a needle-punched web optionally containing low-melting material, followed by laying a second needle-punched web over the scattered layer and re-needling the three layers before applying heat or heat and pressure to activate the low-melting ground material present within the layers. Additional low-melt ground material is optionally blended into the ground textile if low melt components are absent or insufficient to bond the composite. The ground material is driven and dispersed into the surrounding web layers with at least part of the material being adjacent the two outer surfaces. The physical properties of the composite can be adjusted by selecting suitable combinations including but not limited to needling stroke depth, needling density, needle gage, low-melt content, heat finishing conditions, and relative layer weights. The final composites can optionally be reintroduced into the original end use and include significant percentages of recycled material.
