Abstract: Paper and a method for manufacturing the same are provided to remove fluorescence whitening agents of more than 50% from raw pulp in an eco-friendly method, thereby producing paper having excellent quality. Raw pulp is treated with a starch layer containing fluorescence whitening agents at a temperature of 65-85°C and a pH of 7-9. The treated pulp is dissociated using a pulper or a beater while alpha-amylase is added into the treated pulp to hydrolyze the treated pulp. The dissociated raw pulp is passed through a cleaner or a screen to remove external particles and refine a paper material from the dissociated raw pulp. The refined paper material is compressed, and wound around a winder.

Abstract: A striking typed dissociating apparatus for dry fiber and a dissociating method using the same are provided to improve properties of the fiber by increasing a bulk value, yield, average fiber length, and tensile strength. A striking typed dissociating apparatus for dry fiber includes the followings: a plane wing portion of a flat pattern type; a blow blade(160) having a slant wing portion(164) installed on an end side of the plane wing portion; dissociation room(180) in which an upper end is opened while accommodating the blow blade; a motor providing rotation power for the blow blade; a driving pulley connected in the motor; a sub pulley delivered the power of the driving pulley; a power transmission shaft connecting the sub pulley and the blow blade.

Abstract: 본 발명은 α-아밀라아제의 첨가에 의해 형광 증백제의 함량이 감소된 제지 및 그 제조 방법에 관한 것이다. 형광증백제가 포함된 종이를 원료로 하여 재생지를 만드는 과정에 있어서, 원료 펄프의 해리과정에서 α-아밀라아제를 첨가함으로써, 재활용 폐지 내에 포함되어 있는 형광증백제의 약 50% 이상을 제거할 수 있다.
또한, 화합물을 사용하지 않고 효소를 사용하였으므로 친환경적인 방법으로 형광증백제의 함량이 감소된 제지를 제조할 수 있다.
