摘要： The present invention relates to compositions of starch. The compositions consist of an anionic and a cationic starch wherein at least one of the starches is waxy. The compositions are surprisingly not resulting in an agglomerated product when cooked. The compositions are used in paper or cardboard preparation. The compositions are cooked and added at the wet end of the paper production process. This results in a high possible addition level and the use of the size press is abolished. The resulting paper and board are shown to have better characteristics than the paper and board prepared with the same components which have not been mixed prior to addition but which are added separately.

摘要： Modified polysaccharides (such as starches, gums, chitosans, celluloses, alginates, sugars, etc.), which are commonly used in the paper industry as strengthening agents, surface sizes, coating binders, emulsifiers and adhesives, can be combined into a single molecule with amphiphilic hydrocarbons (e.g. surface active agents) which are commonly utilized in the paper industry to control absorbency, improve softness, enhance surface feel and function as dispersants. The resulting molecule is a modified polysaccharide having surface active moieties which can provide several potential benefits, depending on the specific combination employed, including: (a) strength aids that do not impart stiffness; (b) softeners that do not reduce strength; (c) wet strength with improved wet/dry strength ratio; (d) debonders with reduced linting and sloughing; (e) strength aids with controlled absorbency; and (f) surface sizing agents with improved tactile properties.
摘要翻译：通常在造纸工业中用作增强剂，表面尺寸，涂料粘合剂，乳化剂和粘合剂的改性多糖（例如淀粉，树胶，壳聚糖，纤维素，藻酸盐，糖等）可以组合成单分子与造纸工业中通常用于控制吸收性的两亲性烃（例如表面活性剂），改善柔软性，增强表面感觉和作为分散剂的功能。所得分子是具有表面活性部分的改性多糖，其可以提供若干潜在的益处，这取决于所采用的具体组合，包括：（a）不赋予刚度的强度助剂; （b）不降低强度的软化剂; （c）具有改善的湿/干强度比的湿强度; （d）脱落，脱落和脱落; （e）具有受控吸收性的强度助剂; 和（f）具有改善的触觉特性的表面施胶剂。

摘要： Provided by the present invention is a wet-layed, nonwoven sheet which is comprised of metal fiber and metal powder. Generally, the amount of metal fiber comprises from 20 to 95% by weight and the amount of metal comprises from 5 to 80% by weight of the sheet. Such a wet-layed nonwoven sheet is economically preferable to a sheet comprised totally of metal fiber, since the metal powder is much less expensive. Among other factors, the present invention is based upon the recognition that by using various process techniques, the combination of metal fiber and metal powder can be wet-layed to obtain a structure of sufficient strength for subsequent handling and sintering.
