用表面改性的CTMP浆料来生产高强度和高松厚度的纸张，这主要是通过淀粉和C M C(羧甲基纤维素)利用多层或MIX技术吸附在纤维表面上以达到改性的效果。结果表明，CTMP经过表面改性后，在保持紧度的条件下其抄造的纸张平面内和平面外性能是未经改性的2倍多。这可以改善纸张弯曲挺度或降低多层纸板的定量。
用錶麵改性的CTMP漿料來生產高彊度和高鬆厚度的紙張，這主要是通過澱粉和C M C(羧甲基纖維素)利用多層或MIX技術吸附在纖維錶麵上以達到改性的效果。結果錶明，CTMP經過錶麵改性後，在保持緊度的條件下其抄造的紙張平麵內和平麵外性能是未經改性的2倍多。這可以改善紙張彎麯挺度或降低多層紙闆的定量。

This study described some methods used to manufacture strong and bulky sheets made from furnishes contained a broad range of surface modified CTMP. By a multilayer or a MIX concept, starch and CMC are adsorbed on the ifbre surface. It is shown that after such surface treatment, both the in-plane and out-of-plane strength of the sheets made from CTMP can be more than doubled at a maintained density. This can be applied to increase bending stiffness or to reduce the basis weight in multi-ply paperboards.
