However, the sizingdegree, tensile strength and surface strength were damaged to some extent.
但成纸的施胶度、抗张强度及表面强度受到影响。

The experiments showed that the best results was obtained when the blocked polyurethane emulsion was used alone. Various paper strength properties and sizingdegree were all improved to so…
结果表明，单独应用的效果好，纸张物理强度均得到不同程度的提高，并改善了纸张的施胶度等物理性能。

To add mineral composition fiber during the papermaking, the tensile strength of the paper will lower, has no effect to the paper sizingdegree, and also has small effect to the paper brightness.
