High-density absorbent structure |
摘要 |
Low-density uncreped through-air-dried webs containing bleached chemithermomechanical pulp fibers and a wet-strength resin are calendered to significantly increase density and reduce caliper. When wetted, these webs substantially return to their original caliper and density and substantially regain their original fluid-handling characteristics. Consequently these webs are very thin when dry and thick when wet. They can be used for a wide variety of applications, including paper towels, wipers and fluid-handling components for infant care and personal care products.
