SE PRESENTAN PAPELES DE SEDA, EN PARTICULAR PAPELES DE SEDA DENSIFICADOS DE UN DISEÑO PARTICULAR, QUE TIENEN UN TACTO MEJORADO DE SUAVIDAD CUANDO SE TRATAN CON CIERTOS SISTEMAS SUAVIZANTES DE AMIDO DE ACIDO GRASO DE POLIHIDROXIDO QUE SON BIODEGRADABLES. LOS AMIDOS DE ACIDO GRASO DE POLIHIDROXIDO TIENEN LA FORMULA (I) EN DONDE R1 ES H, HIDROCARBILO C{SUB, 1-C}, 2 HIDROXIETILO, 2 - HIDROXIPROPILO, METOXIETILO, METOXIPROPILO O UNA MEZCLA DE LOS MISMOS; R2 ES UN GRUPO DE HIDROCARBILO C{SUB, 5-31}; Y Z ES UNA MOLECULA DE POLIHIDROXIHIDROCARBILO QUE TIENE UNA CADENA DE HIDROCARBILO LINEAL CON AL MENOS TRES HIDROXILOS DIRECTAMENTE CONECTADOS A LA CADENA Tissue papers, in particular pattern densified tissue papers, having an enhanced tactile sense of softness when treated with certain polyhydroxy fatty acid amide softener systems that are biodegradable are disclosed. The polyhydroxy fatty acid amides have the formula: wherein R1 is H, C1-C hydrocarbyl, 2-hydroxyethyl, 2-hydroxypropyl, methoxyethyl, methoxypropyl or a mixture thereof; R2 is a C5-C31 hydrocarbyl group; and Z is a polyhydroxyhydrocarbyl moiety having a linear hydrocarbyl chain with at least 3 hydroxyls directly connected to the chain.
