Abstract

PARTìCULA DE RESINA ABSORVENTE DE áGUA, FAZENDO USO DA MESMA, MATERIAL ABSORVENTE E ARTIGO ABSORVENTE. Partículas de resina absorvente de água, caracterizadas pelo fato de as partículas de resina absorvente de água terem uma capacidade de retenção de água de solução salina fisiológica (X) de 30 a 70 g/g, de a capacidade de retenção de água de solução salina fisiológica (X) e um índice de absorção de água sob pressão (Y) satisfazerem a relação da fórmula: ¢índice de absorção de água sob pressão (Y)!<242>150 - 2¢capacidade de retenção de água de solução salina fisiológica (X)!, e de as partículas de resina absorvente de água terem uma taxa de sucção de liquido da polpa de 20 g/g/5 minutos ou mais; e um material absorvente e um artigo absorvente, em que são usadas as partículas de resina absorvente de água. O material absorvente em que são usadas as partículas de resina absorvente de água pode ser adequadamente usado, por exemplo, em artigos absorventes tais como fraldas descartáveis e tolhas sanitárias.
