绒毛浆用浆板
By controlling the fiber length and width distribution of hardwood and softwood pulps, the problem of reduced absorbency caused by the short fiber length of hardwood pulp was solved, and fluff pulp with high absorbency and good workability was produced.

AI Technical Summary
Wood pulp derived from hardwoods has short fiber lengths, resulting in reduced water absorption and absorption rate in absorbent materials, and poor workability when manufacturing fluff pulp.
By using a specific ratio of bleached hardwood kraft pulp and bleached softwood kraft pulp, the distribution range of fiber length and width is controlled to ensure that the proportion of fibers with a length of 0.5 mm or more and less than 1.1 mm is 42.6% or more, and the proportion of fibers with a width of 10 μm or more and less than 35 μm is 90.6% or more. The uniformity of fiber length and width distribution is also controlled, and the gaps and bonding forces between fibers are optimized.
It improves the absorbency of fluff pulp and the workability during fluff pulp production, reduces the amount of re-seepage of absorbent liquid, and reduces the occurrence of contact dermatitis.
