摘要： An improved processes for making fluff pulp sheets mechanically eliminates many of the unwanted fiber-to-fiber bonding (fiber bundles) which may be contained in the sheet to produce consistent and uniform quality fluff pulp. Pulp slurry is deposited on a moving bottom forming wire to form a stock web. Pulp slurry is brought into contact with a moving top forming wire. The stock web is subjected to up and down dewatering creating separately formed layers to reduce fiber-to-fiber bonding. The stock web can be subjected to strong pulsating shear forces as it is being advanced along the bottom forming wire to break a majority of fiber bundles contained in the web. The pulp slurry can be deposited on the bottom forming wire utilizing a headbox with dilution control to selectively adjust the concentration of the pulp slurry. A shoe press can be used to dewater the web after it is subjected to the pulsating shear forces. The web can be dried utilizing conventional drying equipment, such as cylindrical driers.
摘要翻译： 用于制造绒毛纸浆片的改进方法机械地消除了可能包含在片材中的许多不想要的纤维 - 纤维粘合（纤维束），以产生一致且均匀的质量绒毛浆。 浆料浆料沉积在移动的底部成形网上以形成原料纤维网。 将纸浆与移动顶部成形丝接触。 坯料经过上下脱水，形成分开形成的层，以减少纤维与纤维的粘结。 当织物沿着底部成形丝线前进时，该卷材可以受到强烈的脉动剪切力，以破坏包含在纤维网中的大部分纤维束。 纸浆可以利用具有稀释控制的流浆箱沉积在底部成形网上，以选择性地调节纸浆的浓度。 可以使用靴式压榨机在经受脉动剪切力之后对织物进行脱水。 可以使用常规的干燥设备（例如圆柱形干燥器）干燥网。
