Abstract: A fibrous sheet having a basis weight of between 20 and 1000 g/m2 that disintegrates in water, has 10% to 70% starch on the basis of the total weight of the dry fibrous sheet. The disintegration time in water, measured in accordance with standard NF Q34-020 applied to a specimen of the sheet of 9×8 cm2, is less than 50 seconds. A loss of strength of the sheet measured in accordance with a defined table test corresponds to a loss of strength of a specimen of said sheet forming an angle of at least 85° after having being wetted with water for a duration of 6 seconds, and/or a residual wet strength of the sheet relative to its dry strength, as measured according to a defined ring crush test, is less than 1%. The fibrous sheet may be used for the manufacture of a water disintegrable core in a roll of tissue paper.

Abstract translation: 基于干纤维片材的总重量，具有在水中分解的基重为20-1000g / m 2的纤维片材具有10％至70％的淀粉。 按照标准NF Q34-020测量的在水中的崩解时间为9×8cm 2的样品，小于50秒。 根据规定的表测试测量的片材的强度损失对应于在用水润湿6秒之后形成至少85°的角度的所述片材的试样的强度损失和/ 或根据定义的环形破碎试验测量的片材相对于其干强度的残余湿强度小于1％。 纤维片材可以用于制造薄纸卷中的水分解芯。
