Sida hermaphrodita Rusby as a papermaking raw material -chemical and morphological characteristics.

Abstrakt

A continuallyincreasing demand forpapermaking materials and simultaneously growing disproportion between therequestfor fiber and the limited resources of woodhaveforced scientists and the papermaking industry to search for the new sources of fibrous raw materials. Anew promising set of raw materials for papermaking comes fromenergy crops. This paper presents Sida hermaphroditaRusby L., as a non-woody raw material forpapermaking. From the studies of chemical composition,it follows that cellulose content of more than 40% characterizes phloem of stems and branches, whereas in xylem exhibits more than 32%. The lowest is the concentration of cellulose in leaves and flowers of Sida. The content of lignin is lower than 24% and 16% in stem xylem and phloem, respectively. In Sida,hemicelluloses and mineral substances stand for being not more than 30% and 2%, respectively. The morphology of Sida cells is similar to hardwood,with fiber length of 0.383, 0.470 and 1.025 mm for parenchyma, xylem,and phloem, respectively. The chemical composition of Sida hermaphroditatogether with its morphological characteristics make this raw material suitable for a production of papers intended for printing, writingand tissue.
