发明名称 IMPROVED SYSTEM FOR MAKING ABSORBENT PAPER PRODUCTS.
摘要 An improved absorbent consumer paper product such as toilet tissue and a method and system for making such a product involves an improved drying fabric that forms an aesthetically pleasing and functionally superior pattern on the paper web before creping. The drying fabric is characterized by a plurality of shute threads extending substantially parallel to each other in a cross-direction of the drying fabric; and a plurality of warp threads extending substantially parallel to each other in a machine direction of the drying fabric. The shute and warp threads are woven together so as to define a number of relatively long warp knuckles at locations where one of said warp threads crosses over at least four of the shute threads. The long warp knuckles are positioned in a shed pattern so as to form (a) a first axis of bulky ridges that are defined by long warp knuckles which are positioned next to each other on adjacent warp threads, the first axis being disposed at a first angle with respect to the cross-direction of the drying fabric that is substantially within the range of greater than 68 degrees but less than 90 degrees; and (b) a second axis formed by each of the long warp knuckles with other, overlapping long warp knuckles on nearby, but not immediately adjacent, warp threads, the second axis forming a second angle with respect to the cross-direction of the drying fabric and being less than about 28 degrees. This pattern improves crepeability of the web and forms a bulky, absorbent, soft tissue product characterized by parallel, continuous low density ridges of substantially uncompressed fibers.
