摘要： The invention relates to a process for the production of paper or nonwoven fibres comprising the steps of adding thermally expandable microspheres comprising a thermoplastic polymer shell and a propellant entrapped therein to a stock comprising fibres or to a web of fibres, forming paper or nonwoven from the stock or the web, and applying heat to raise the temperature of the microspheres sufficiently for them to expand and thereby increase the bulk of the paper or the nonwoven, wherein said expandable microspheres comprise from about 17 to about 40 wt % propellant and have a volume-average diameter from about 17 to about 35 µm. The invention also concerns certain expandable microspheres and use thereof.
摘要翻译：本发明涉及一种用于生产纸或非织造纤维的方法，包括以下步骤：将包含热塑性聚合物外壳和其中包含的推进剂的热膨胀性微球添加到包含纤维的原料或纤维网上，从而形成纸或非织造布并且加热以提高微球的温度以使它们膨胀，从而增加纸或非织造材料的体积，其中所述可膨胀微球包含约17至约40重量％的推进剂，并具有体积 - 平均直径约17至约35μm。本发明还涉及某些可膨胀微球及其用途。

摘要： The invention relates to a process for the production of paper or nonwoven from fibres comprising the steps of adding thermally expandable microspheres comprising a thermoplastic polymer shell and a propellant entrapped therein to a stock comprising fibres or to a web of fibres, forming paper or nonwoven from the stock or the web, and applying heat to raise the temperature of the microspheres sufficiently for them to expand and thereby increase the bulk of the paper or the nonwoven, wherein said expandable microspheres comprise from about 17 to about 40 wt % propellant and have a volume-average diameter from about 17 to about 35 μm.
