Resumen

TURRADO, José; SAUCEDO, Alma R; RAMOS, Juan  y  REYNOSO, Maria L. Behavior of Recycled Cellulose Fiber during the Hydration Process. Inf. tecnol. [online]. 2008, vol.19, n.5, pp. 129-136. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642008000500014.

In this work the phenomenon of hydration is studied in recycled fiber. As raw material kraft of the first cycle (sample A) is used and results compared with recycled kraft fiber of the n cycle (sample B). Both fibers are separately treated under hydration conditions. Later, fibers A and B are mixed, 50 % each, generating a fibrous mixture to manufacture a new paper sheet. As response factors the following were evaluated: tensile resistance, elongation, tensile absorption energy and water retention value (gwater/gfiber). The hydration is carried out with: water, sodium hydroxide and two surface active agents with moisture activity. In water the mixture of fibbers reaches its maximum capacity of water absorption (1,2 gwater/gfiber) in 18 h, in alkaline solution (1,4 gwater/gfiber) and in surface active agent (1,3 gwater/gfiber) in 1 h.

Palabras clave : hydration; recycled fiber; kraft pulp.
