Abstract

The non-wood pulps have a fiber length greater than about 1.70 mm and a porosity of about 100 cfm or greater. The relatively high degree of porosity is achieved without a loss in tensile strengths. The high degree of porosity and strength makes 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 plant biomass is cut to size prior to pulping.
