摘要:分析了涤纶、天丝、黏胶纤维与针叶木浆配抄对医用垫单纸强度、透气量、柔软性及Cobb值的影响，研究了针叶木浆打浆度、涤纶纤维长度和用量、浸渍液种类及起皱处理对医用垫单纸性能的影响。结果表明，配比天丝纤维的纸张强度、柔软性较差，黏胶纤维纸张透气性较差，涤纶纤维更适用于医用垫单纸；10 mm涤纶纤维比5 mm涤纶纤维更利于纸张的强度、柔软性和透气性；针叶木浆打浆度的增加有利于纸张强度而不利于透气性和柔软性，20°SR较为适宜；涤纶纤维用量20%时纸张的强度较高、匀度好且柔软透气；不同乳液（R1、R2、R3）浸渍后，纸张强度R3>R1>R2，抗水性R1>R3>R2，起皱后强度R3>>R1>R2，R1和R3以1∶1比例混合浸渍，可制得与进口医用垫单纸产品性能相当、抗水阻隔性好且起皱后强度性能优良的医用垫单纸。

Abstract:The effects of blending polyester， Tencel， and viscose fiber with softwood pulp on the strength， air permeability， softness， and Cobb value of disposable medical pad sheet paper were analyzed. Meanwhile， the effects of beating degree of softwood pulp， length and dosage of polyester fiber， type of impregnation solution， and wrinkling treatment on the properties of pad sheet paper were studied. The results showed that the paper containing Tencel fiber had lower strength and softness， the paper containing viscose fiber had lower air permeability， while polyester fiber was more suitable for preparing pad sheet paper. Moreover， polyester fiber which had a length of 10 mm was more conducive to the strength， softness， and air permeability of the paper than that of its 5 mm counterpart. The increase of beating degree of softwood pulp was beneficial to strength but not conducive to air permeability and softness， and 20°SR was a feasible value for beating degree. When the polyester content was 20%， the paper had high strength， good uniformity， softness， and air permeability. Using different emulsion（R1， R2， and R3） to impregnate paper， the strength order of impregnated papers was R3>R1>R2， water resistance order R1>R3>R2， and the wrinkled strength order R3>>R1>R2. Impregnate base paper with mixed R1 and R3 emulsion of 1∶1 ratio to prepare pad sheet paper， the paper had good strength and water resistance after wrinkling， and the properties were comparable to the imported medical pad sheet paper.
