摘要：
A high efficiency disposable cellulosic wiper includes (a) pulp-derived papermaking fiber; (b) up to 75% by weight regenerated cellulosic microfiber having a characteristic CSF value of less than 175 ml, the microfiber being selected and present in amounts such that the wiper exhibits a Laplace pore volume fraction at pore sizes less than 15 microns of at least 1.5 times that of a like wiper prepared without regenerated cellulose microfiber. The wipers of the invention exhibit remarkable residue removal efficiency.
