    • A process for incorporating a fine non-cellulosic particulate filler into a creped tissue paper comprises the steps of: a) contacting an aqueous dispersion of a non-cellulosic particulate filler (34) with an aqueous dispersion of an anionic polyelectrolyte polymer (35); b) mixing the aqueous dispersion of polymer-contacted filler (38) with papermaking fibers forming an aqueous papermaking furnish (41) comprising polymer-contacted filler and papermaking fibers; c) contacting said aqueous papermaking furnish (41) with a cationic retention aid (46); d) forming an embryonic paper web (88) from the aqueous papermaking furnish (45) on foraminous papermaking clothing (85); e) removing water from said embryonic web (88) to form a semi-dry papermaking web; f) adhering the semi-dry papermaking web to a Yankee dryer (108) and drying said web to a substantially dry condition; g) creping the substantially dry web from the Yankee dryer by means of a flexible creping blade (111), thereby forming a creped tissue paper (70). When providing at least one additional papermaking furnish (31, 33) and directing said papermaking furnishes (31, 33; 45) onto foraminous papermaking clothing (85), thereby forming an embryonic multi-layered paper web (88) from the filler-containing aqueous papermaking furnish and the additional parpermaking furnish in a manner to create a multi-layered paper web wherein at least one layer (88b, 88c) is formed from the filler-containing aqueous papermaking furnish and at least one layer (88a) is formed from said additional papermaking furnish, a multi-layered creped tissue paper (70) can be formed. The process results in strong, soft, and low dusting tissue paper webs useful in the manufacture of soft, absorbent sanitary products such as bath tissue, facial tissue, and absorbent towels.
    • 将精细非纤维素颗粒填料掺入起皱纸巾中的方法包括以下步骤:a)使非纤维素颗粒填料(34)的水分散体与阴离子聚电解质聚合物(35)的水分散体接触; b)将聚合物接触填料(38)的水性分散体与形成含有聚合物接触填料和造纸纤维的水性造纸配料(41)的造纸纤维混合; c)使所述水性造纸配料(41)与阳离子助留剂(46)接触; d)从多孔造纸服装(85)上的水性造纸配料(45)形成胚胎纸幅(88); e)从所述胚胎网(88)中去除水以形成半干式造纸纤维网; f)将半干式造纸纤维网粘附到扬克烘干机(108),并将所述纸幅干燥至基本干燥的条件; g)通过柔性起皱刀片(111)从扬克烘干机起皱基本干燥的纤维网,从而形成起皱纸巾(70)。 当提供至少一个另外的造纸配料(31,33)并将所述造纸配料(31,33,45)引导到有孔造纸服装(85)上时,由含有填料的成型纸形成一个胚胎多层纸幅(88) 水性造纸配料和附加的制蜡配料,以产生多层纸幅,其中由含填料的水性造纸配料形成至少一层(88b,88c),并且至少一层(88a)由 所述附加造纸配料可以形成多层起皱纸巾(70)。 该方法产生用于制造柔软,吸收性卫生产品如浴巾,面巾纸和吸收性毛巾的强力,柔软和低粉尘的纸幅。
