Tissue paper webs useful in the manufacture of soft, absorbent products such as paper towels, and processes for making the webs. The process comprises the steps of forming an aqueous papermaking furnish from paper pulp, at least one specified quaternary ammonium compound and at least one specified nonionic surfactant. The quaternary ammonium compounds are trimethylalkyl, trimethylal- kylene, methylpolyoxyethylene alkyl and methylpolyoxyethylene alkylene quaternary ammonium compounds. The nonionic surfactants are ethylene oxide adducts of fatty alcohols and fatty acids. The second and third steps in the basic process are the deposition of the papermaking furnish onto a foraminous surface, such as a Fordrinier wire and removal of the water from the deposited furnish. An alternate process involves the use of the furnish containing the quaternary ammonium compounds and the nonionic surfactants in a papermaking process which will produce a pattern densified fibrous web having a relatively high bulk field of relatively low fiber density in a patterned array of spaced zones of relatively high fiber density.
用于制造柔软吸水性产品(如纸巾)的卫生纸网,以及制造卫生纸网的工艺。该工艺包括以下步骤:用纸浆、至少一种特定的季铵盐化合物和至少一种特定的非离子表面活性剂形成水性造纸原料。季铵盐化合物为三甲基烷基、三甲基亚烷基、甲基聚氧乙烯烷基和甲基聚氧乙烯亚烷基季铵盐化合物。非离子表面活性剂是脂肪醇和脂肪酸的环氧乙烷加合物。基本工艺的第二步和第三步是将造纸原料沉积在有孔表面上,如福氏网,然后从沉积的原料中除去水分。另一种工艺是在造纸过程中使用含有季铵盐化合物和非离子表面活性剂的纸浆,这种纸浆将产生一种图案致密的纤维网,这种纤维网具有相对较高的纤维密度,而纤维密度相对较低,纤维密度相对较高的间隔区呈图案排列。
