Abstract

본 발명은 흡수성수지입자 100중량부와 50∼200℃의 온도에서 접착성을 발현하는 수지분말 0.5∼30중량부로 이루어진 흡수제에 관한 것이다. 또 본 발명은, 흡수성 수지입자, 50∼200℃의 온도에서 접착성을 발현하는 수지분말 및 섬유상기재로 이루어지며, 수지분말의 열접착성을 발현하는 온도를 넘는 온도에서 처리하므로써, 이 수지를 개재해서 흡수성수지입자와 섬유상기재가 고착된 흡수재료 및 이것을 사용한 흡수성물품에 관한 것이다.
본 발명의 흡수제는, 흡수성수지가 본래가진 흡수특성을 유지한 그대로, 섬유에 대한 고착성에 뛰어난 흡수재를 얻게된다. 따라서, 종리기저귀, 생리용품등의 위생재료용의 원료로서 유용하다.
또, 본 발명의 흡수재료는, 흡수성능, 흡수속도, 흡수후의 형상유지성에 뛰어난다. 따라서, 종이기저귀, 생리용품등의 흡수성물품에 유용한 것이다.
