Abstrakty

The breathability, strength, structural and optical properties of bleached kraft pulps from blends of birch or pine with hemp stalks in a proportion of 80/20 weight % were studied. It was found that these pulps generally have comparable properties to those of bleached pulps from birch and pine. The properties of bleached pulps produced from 80/20 weight % blends of pine or birch with hemp woody-core such as the breaking length, burst, and light scattering proved to be comparable or better than those of bleached pulps from wood. However, the replacement of a part of birch or pine with hemp-woody core negatively affected their bulk, air-resistance, and tearing resistance. Taking into consideration the results presented in Part I and Part II of the study, it can concluded that hemp stalks are better fibrous raw material for the manufacturing of papermaking intermediates partially free of wood fibres than hemp woody-core.

W pracy zbadano podatność na mielenie oraz właściwości strukturalne, optyczne i wytrzymałościowe bielonych mas celulozowych wytworzonych z mieszanek drewna brzozy i sosny z łodygami konopnymi o udziale tych łodyg odpowiednio 80 i 20% wag. Stwierdzono, że właściwości tych mas celulozowych są zbliżone do właściwości bielonych mas celulozowych brzozowej i sosnowej. Co się tyczy bielonych mas celulozowych z mieszanek drewna brzozy i sosny z drewnikiem konopnym to ich właściwości takie jak: samozerwalność, przepuklenie i zdolność do rozpraszania światła również okazały się porównywalne lub nawet lepsze, niż w przypadku bielonych mas brzozowej i sosnowej. Zastąpienie części drewna drewnikiem konopnym wpływało jednak ujemnie na objętość właściwą, przepuszczalność powietrza, a także odporność na przedarcie arkusików mas celulozowych. Biorąc pod uwagę wyniki przedstawione w części I i II pracy, można zatem stwierdzić, że łodygi konopne są lepszym surowcem włóknistym do wytwarzania częściowo wolnych od włókien drewna papierniczych półproduktów włóknistych, niż drewnik konopny.

Bibliografia

1. Replacement of 1/5 of wood with hemp stalks and hemp woody-core changes the SR-freeness of bleached kraft pulps from these blends by 3-5.5°SR after their moderate beating in a Jokro mill.
2. Bleached kraft pulps from wood/HFRM blends are characterised by good strength as well as structural and optical properties, which are generally comparable with those of bleached pulps from birch and pine.
3. The good tensile strength and burst of such pulps are due to the presence of woody-core fibres, while the good bulk and tear are the effect of the presence of long, primary and secondary bast fibres, which are slightly susceptible to flattening.
4. The breaking length, burst strength, and optical properties of bleached kraft pulps from wood/hemp woody-core blends are comparable with or better than those of bleached birch and pine kraft pulps. However, the replacement of a part of birch and pine with hemp-woody core negatively affects the bulk, and air and tear resistance of the bleached kraft pulps produced.
5. Taking into consideration the results presented in Part I and Part II of the study, one can conclude that hemp stalks are better fibrous raw material for the production of papermaking intermediates partially free of wood fibres than hemp woody-core.
