Abstract: Disclosed are non-wood pulps having a fiber length greater than about 1.70 mm and a brightness of about 80% or greater. The relatively high degree of brightness is achieved without a loss of fiber length or pulp yield. The high degree of brightness and relatively long fiber length make the pulps well suited for the manufacture of wet-laid fibrous products, particularly wet-laid tissue products. The pulps may be prepared from plants of the family Asparagaceae by mechanical pulping and more preferably by a chemi-mechanical pulping using a sodium hydroxide alkaline peroxide solution where the primary pulp is cleaned to reduce debris prior to bleaching. Preferably the cleaned primary pulp has less than about 5 wt % debris prior to bleaching.

Abstract: The single ply creped webs and products are generally durable, flexible and highly dispersible. The single ply creped webs and products may have a Slosh time less than 1 minute, and more preferably less than about 30 seconds, and a wet cross-machine direction (CD) tensile strength greater than about 100 g/3?. The single ply creped webs and products may be produced by a print crepe process that disposes a latex binder, particularly a non-cross linked latex binder, on at least one of the product's outer surfaces. The presence of a latex binder on the product's outer surface generally increases product durability and flexibility without negatively affecting dispersibility.
