“…As a filler, kaolin is used. This makes it possible to provide the required level of opacity, but the paper obtained in this way has a high mass of 1 m 2 to 200 g/m 2 [5]. According to results of theoretical calculations based on the dependence of GurevichKubelka-Munk, one should note that it is almost impossible to achieve the desired level of opacity of paper with a mass of 1 m 2 -60-65 g using kaolin as a filler.…”

Розроблено спосіб виробництва пакувального паперу підвищеної непрозорості, білості та міц ності. Він полягає у виготовленні паперу з волокон сульфатної біленої целюлози з хвойної і листяної деревини з додаванням тонкоподрібнених волокон целюлози, діоксиду титану і полівінілового спирту. Це дозволяє підвищити розривну довжину паперу, білість, непрозорість, фарбосприйняття та стій кість друку, знизити лінійну деформацію пеперу Ключові слова: упакування, харчові продукти, властивості товарів, полівініловий спирт, діоксид титану, волокна целюлози, формування паперу, каолін, чіткість друку Разработан способ производства упаковоч ной бумаги повышенной непрозрачности, белизны и прочности. Он заключается в изготовлении бу маги из волокон сульфатной беленой целлюлозы из хвойной и лиственной древесины с добавлением тонкоизмельченных волокон целлюлозы, диокси да титана и поливинилового спирта. Это позво ляет повысить разрывную длину бумаги, белизну, непрозрачность, цветовосприятие и устойчивость печати, снизить линейную деформацию бумаги Ключевые слова: упаковка, пищевые продукты, свойства товаров, поливиниловый спирт, диоксид титана, волокна целлюлозы, формирование бума ги, каолин, четкость печати UDC 676.248

“…Whatman #1 filter paper used in this study was made of pure cellulose fibres with no additives such as strengthening or whitening agents. The basic structure of untreated paper is composed of cellulose fibers that are firmly bond together through hydrogen bonding (Sahin and Arslan 2008). This kind of paper has inactive, slightly anionic surface with a low, negative, surface-charge density .…”

Cellulose paper specimens with and without surface modification were compared in order to study their physicochemical compatibility with quantum dots (QDs) for biochemical sensing applications. Silane and chitosan modification methods were applied. The distribution of QDs deposited on untreated paper and papers modified with silane and chitosan were investigated in order to understand the interaction between QDs and fibre. Modified papers were shown to significantly reduce the undesirable redistribution of QDs during paper drying. The retention ability and thermal resistance of QDs to the loss of fluorescence on modified papers were also studied for the purpose of determining the most suitable paper surface modification for developing QD-Paper-based analytical devices (QD-PADs). Furthermore, chitosan-modified paper was used to design QD-PADs to quantify glucose concentration in aqueous samples; the quenching effect of the enzymatic product on the fluorescent emission of QDs was used as the indicator system. The change of fluorescence of QDs was measured by a simple in-house constructed fluorescence imaging system. The detection limit of glucose was 5 mg/dL, which is comparable with other reported paper sensors for detection of glucose.
