摘要： A package dispenser for dispensing at least one stack of wipes, and having a bottom, top, two opposing side and two opposing end walls deliminating a storage space, wherein,
the top wall includes at least one dispensing opening; each of the at least one stack of wipes has a bottom surface, a top surface, two side and two end surfaces, each of the at least one stack of wipes resting on the bottom wall of the package dispenser, the top surface of the stack facing the top wall of the package dispenser;
each of the at least one stack of wipes in the package dispenser is a stack of interfolded wipes; and
arranged to be dispensed from the top surface of the stack, the interfolded wipes in the stack being dispensed through a corresponding one of the at least one dispensing opening.-

摘要： A process for producing nonwoven materials is disclosed. The process of comprises the following steps: a) providing a three-phase (gas-liquid-solid) suspension containing: the natural and/or manmade fibres; a surfactant; 20-48 vol. % of air, b) providing a first moving carrier sieve, c) applying the three-phase suspension onto the first moving carrier sieve to produce a fibrous web, d) removing aqueous residue of the three-phase suspension through the first carrier sieve, e) recycling the aqueous residue to step a), f) pre-integrating the fibrous web by flushing the web with 0.0005-0.05 m3 of water per m3 of applied three-phase suspension, at a pressure of 5-50 bar, and collecting flushed water, g) transferring the pre-integrated fibrous web from said first moving carrier sieve to a second moving carrier sieve, said second moving carrier sieve having a porosity which is smaller than the porosity of said first moving carrier sieve, h) hydroentangling the fibrous web on said second moving carrier.

摘要： A process and an apparatus for producing nonwoven materials are disclosed. The process comprises the following steps: a) providing a three-phase (gas-liquid-solid) suspension containing air, water, fibrous material and a surfactant, b) depositing the suspension onto a moving carrier sieve to produce a fibrous web on the carrier, c) removing aqueous residue of the suspension through the carrier sieve, d) conveying the aqueous residue through one or more phase separation tanks in an essentially horizontal direction while providing a depressurised headspace above the aqueous residue, e) recycling the aqueous residue conveyed in step d) to step a), f) preferably pre-integrating the fibrous web.

摘要： A process for producing nonwoven materials is provided. The process includes: providing a three-phase (gas-liquid-solid) suspension, providing a first moving carrier sieve, applying the three-phase suspension onto the first moving carrier sieve to produce a fibrous web, removing aqueous residue of the three-phase suspension through the first carrier sieve, recycling the aqueous residue, pre-integrating the fibrous web by flushing the web with water and collecting flushed water, transferring the pre-integrated fibrous web from the first moving carrier sieve to a second moving carrier sieve, and hydroentangling the fibrous web. The three-phase suspension contains natural and/or manmade fibres, a surfactant, and air.
