  • Description: A non-wood pulp having a fiber length of greater than about 1.70 mm and a porosity of about 100 cfm or greater is disclosed. A relatively high porosity is achieved without loss of tensile strength. The high porosity and strength makes the pulp well suited for the manufacture of wet-laid fibrous products, in particular wet-laid tissue paper products. The pulp may be prepared from a plant of the family Asparagaceae by mechanical pulping, and more preferably by chemical mechanical pulping using a sodium hydroxide alkaline peroxide solution, where the plant biomass is cut to size prior to pulping. 公开了非木纸浆，所述非木纸浆具有大于约1.70mm的纤维长度和约100cfm或更大的孔隙率。在不损失拉伸强度的情况下实现了相对高的孔隙率。高孔隙率和强度使得所述纸浆非常适合于制造湿法成网纤维产品，特别是湿法成网薄页纸制品。所述纸浆可以由天门冬科植物通过机械制浆制备，并且更优选地通过使用氢氧化钠碱性过氧化物溶液的化学机械制浆制备，其中植物生物质在制浆前被切割成一定尺寸。
