摘要
以中浓、低浓打浆相结合的多段打浆工艺为基础,采用涤纶超短纤维与针叶木浆混抄方法,制备高透气度纸袋纸。结果表明,针叶木浆采用中浓(浆料浓度10%,打浆至18 oSR)+低浓(浆料浓度6%,打浆至20 oSR)两段打浆的方法,所抄纸张各项物理强度性能较佳且透气度可达11.23μm/(Pa·s)。随着涤纶超短纤维添加量的提高,纸袋纸的孔隙率与透气度随之提高。当涤纶超短纤维添加量为5%~10%时,纸袋纸透气度可达28.13~47.48μm/(Pa·s),各项物理强度性能均能满足使用要求。
Based on the multi-stage beating process with a combination of medium and low consistency beating process, a high permeability sack paper was prepared by blending polyester ultra-short fibers and softwood pulp. The results showed that the paper prepared by the twostage beating process of medium consistency(pulp consistency of 10%, beating degree of 18 oSR) and low consistency(pulp consistency of 6%, beating degree of 20 oSR) had better physical strength properties with air permeability of 11. 23 μm/(Pa·s). With the increase of polyester ultra-short fibers dosage, the porosity and air permeability of sack paper increased. When the dosage of polyester ultra-short fibers was 5%~10%, the air permeability of the sack paper could reach 28. 13~47. 48 μm/(Pa·s), and all of the physical strength properties could meet the requirements.
