Process for producing a strengthened fiber assembly |
| abstract |
The invention relates to a process for producing a strengthened fiber assembly containing cellulosic fibers with the cellulose being present in the crystalline structure of cellulose II, by contacting the fiber assembly with an aqueous solution of N-methylmorpholine-N-oxide (NMMO) at elevated temperature and subsequently washing the fiber assembly, characterized in that contacting is effected in a manner that from the relation-947+0.30xlog(10)t+0.046xT-3.53xC +645xlog(10)Cwherein t indicates the time in minutes during which the fiber assembly is contacted with the aqueous NMMO solution, T indicates the temperature of the aqueous NMMO solution in DEG C. and C is the concentration of NMMO in % by mass, based on the aqueous NMMO solution, a number in the range of 0.30 to 1.70 results with the proviso that the temperature T is smaller than 130 DEG C. and the concentration C ranges between 70 and 84 % by mass. |
