Title:
真空紫外線を用いた方法により製造される表面架橋超吸収性ポリマー粒子を備えた吸収性物品
Document Type and Number:
Japanese Patent JP4813555
Kind Code:
B2
Abstract:
The present invention relates to absorbent articles comprising surface cross-linked superabsorbent polymer (SAP) particles, the SAP particles being made by a method using UV irradiation. The method is carried out in a so-called drum reactor, which comprises a hollow drum and an irradiation source. The drum has a longitudinal axis and a cross-section. Superabsorbent polymer particles are fed into the drum and are irradiated while they move within the drum, which is rotated around its longitudinal axis. The irradiation source is provided such that the radiation emitted by the irradiation source is able to reach superabsorbent polymer particles within said drum. The irradiation source for use in the method of the present invention is able to emit UV radiation of a wavelength between 100 nm and 200 nm.
