    Abstract: The invention relates to a package intended for thermal treatment comprising a fibre-based packaging material treated with a hydrophobic size and comprising one or more layers for reduced water penetration outside and/or inside the fibre substrate. The package of the invention is characterised by the fibre substrate being treated with a combination of a wet-strength size, a hydrophobic size and an aluminium and/or calcium compound for increased heat resistance of the packaging material, and in that the ratio of hydrophobic size to the aluminium and/or calcium compound is 1:1-1:10.

    Abstract: The present invention provides a method for production of cellulose ethers in a high solids process substantially without use of organic solvents as reaction and/or washing medium. In the method of the invention the first alkalization step is carried out by using high solids content cellulose pulp and solid sodium hydroxide. This is followed by an etherification step where the solids content is preferably further increased and the use of solid etherification reactant is preferred. As no organic solvents are used as reaction media the invented method enables production of cellulose ethers directly from never dried pulp with significant savings in energy and investment costs. The method is especially suitable for the production of carboxymethyl cellulose sodium salt (CMC) with low degree of substitution (DS

    Abstract translation: 本发明提供了一种基本上不使用有机溶剂作为反应和/或洗涤介质的高固体分离过程中生产纤维素醚的方法。 在本发明的方法中,通过使用高固体含量的纤维素纸浆和固体氢氧化钠来进行第一碱化步骤。 之后是醚化步骤,其中固体含量优选进一步增加,并且优选使用固体醚化反应物。 由于不使用有机溶剂作为反应介质,所以本发明的方法能够直接从未干燥的纸浆生产纤维素醚,从而显着节省能源和投资成本。 该方法特别适用于低取代度(DS <0.3)的羧甲基纤维素钠盐(CMC)的生产。 所得到的无水或低水溶性羧甲基化纤维素纤维的使用适用于例如用于生产微纤化纤维素。
