Abstract
The bulk and absorbency of multi-ply tissue products can be improved by brushing at least one surface of at least one ply of the tissue and plying the tissue product together such that at least one brushed surface is facing inwardly, i.e. is in the middle and not on the outside of the multi-ply product.
Claims30
In a method for making a multi-ply tissue in which an aqueous slurry of papermaking fibers is continuously deposited onto a traveling foraminous fabric, dewatered, and dried to form a first tissue web, said first tissue web being combined with one or more other tissue webs to form a multi-ply tissue, the improvement comprising brushing at least one surface of the first tissue web to increase the extent to which fibers protrude from the brushed surface of the first tissue web and combining the first tissue web with the other one or more tissue webs to form a multi-ply tissue such that the brushed surface of the first tissue web is facing inwardly.
A method of making a two-ply tissue comprising:
- (a) continuously forming a web by depositing an aqueous slurry of papermaking fibers onto an endless foraminous fabric;
- (b) dewatering and drying the web;
- (c) creping the dried web;
- (d) brushing a surface of the creped web with a rotating brushing surface to increase the extent to which fibers protrude from the brushed surface;
- and with each other.
A method of making a two-ply tissue comprising:
- (a) continuously forming a first web by depositing an aqueous slurry of papermaking fibers onto an endless foraminous fabric:
- (b) dewatering and drying the first web;
- (c) creping the first web;
- and
- (d) combining the first web with a second web, wherein prior to combining, each web is simultaneously and separately introduced into one of two separate nips formed between two backing rolls and a common rotating brush roll in which one surface of each web is brushed, the two webs being combined into a two-ply tissue with their brushed surfaces in contact with each other.
A multi-ply tissue having two outer surfaces and two or more internal ply surfaces, wherein the Profile Index of at least one of the internal ply surfaces is greater than the Profile Index of the outer surfaces and wherein the Profile Index of at least one of said internal ply surfaces has a Profile Index of at least about 3.
