As far as the processing is concerned, there are some variations, but the basic principle remains unchanged. The selection of the Japanese paper, the adhesive, and the method of treatment is determined by damage symptoms and object characteristics. In this context, and because of the fact that in many cases local damage has to be treated, the development and the increased use of coated stabilizing papers remoistenable and heat-set tissues represents an interesting methodical approach.

Effect of Surface Size With Starch

They allow for easier processing of the very thin Japanese tissue papers, a standardization of the adhesive quantity, and the minimization of the influence of moisture or better humidity control during the paper stabilization phase [ 7 , 8 ].

For this purpose, fabrication and processing technologies are helpful [ 7 , 8 , 9 ]. Different types of nanocellulose can be interesting as a novel and innovative materials for paper stabilization due to their strong structural similarity to the paper matrix i. But there are considerable differences at the level of fiber morphology. The nanocelluloses of plant origin and of bacterial origin are characterized by common specific properties that are caused by their molecular construction and their structures in the nanometre range.

However, considerable differences are mainly resulting from different production processes.

An essential difference lies in the purity level of the nanocelluloses. After a thorough cleaning, BNC can be produced with the highest degree of purity [ 12 ].

For both materials, the emerging nano-dimensions require large fibre surfaces that, in turn, cause strong interactions with substances of the environment [ 11 , 12 , 13 ]. Bacterial nanocellulose has unique selling points in comparison to cellulose of plant origin due to the manufacturing process. It is synthesized by bacteria of the species Gluconacetobacter. During in situ or after post biosynthesis, the development of cellulose i.

After less complex cleaning cooking in sodium hydroxide solution and washing compared to the isolation of NFC, bacterial products can be directly used. Moreover, BNC has a very high molecular weight species depending, around DP , a high degree of crystallinity, and a distinct mechanical strength [ 12 , 14 ].

At the same time, it is also believed that it has an exceptional level of chemical and thermal stability [ 15 ]. The high water retention capacity of the undried BNC is one of its characteristic features [ 12 , 14 , 16 ].

It stores large quantities of water in fibre suspensions that prevent irreversible creations of fibre agglomerates [ 12 , 15 ].

Nanofibrillated cellulose is isolated from cellulosic fibres by using a mechanical or chemo-enzymatic-mechanical treatment top-down-methods. That means structures are extracted from a fibre network by defibrillation [ 17 ].

The aim is to split fibres into micro- and nanofibrils without changing the high aspect ratio. Chemical pulp like kraft or sulfite pulp , vegetable fibres of agricultural or waste products, or fast-growing plants like eucalyptus, sisal, or ramie [ 18 , 19 ] provide the source of raw materials.

Furthermore, unbleached pulp can be fibrillated [ 20 ], which is a particularly interesting aspect with reference to ancient paper shades. Consequently, it might be possible with respect to NFC to influence the outcome through various parameters during or after the production process.

Important key data of NFC are size and size distribution of the fibrils. NFC has also a very good water retention capacity [ 10 , 18 ] and distinct mechanical strength properties [ 18 ]. Due to their positive characteristics, like strength increasing and film generating features, they are more and more used for various purposes as additives in the paper industry [ 12 , 21 , 22 ].

This part of ISO also specifies equations for calculating the tensile index, the tensile energy absorption index, the tensile stiffness index and the modulus of elasticity.

ISO Set up a giveaway. If the elongation is determined with the lower accuracy, the tensile stiffness value obtained is not in accordance with this part of ISO Follow these links to find other Standards similar to the one you are viewing. Print strength with a 3 bar increased by 2. At the end of these measurements, the average print density values of unsized and sized paper samples were obtained. The changes in surface sizing and paper basis weights are given in Table Tensile index values of parchment and sulfite papers Without With With Without With With sizing sizing 2 sizing 3 sizing sizing 2 sizing 3 Fig.

The strength value of sulfite papers increased more clearly and sharply Fig. This implies kPa. However, in the parchment papers this that the strength of paper surfaces against water increased, value reached up to 0. The felt and wire surfaces of parchment paper with or without sizing are more resistance against water than sulfite papers.

For both types of paper, water resistance of wire surfaces was much more than that of felt surfaces. The felt-surface water resistance of the parchment base paper increased The felt-surface water resistance of the sulfite base paper increased The tension strengths in machine direction MD were found out as twice as the tension strength in cross-machine direction CD for both kind of paper samples i.

Print density values of sulfite papers wire surface paper samples with a 2 bar were slightly higher than the print Fig. Nevertheless, after 24 h, the print density values of printed-unsized paper samples significantly decreased relative to the print density values of printed-sized paper samples with 2 and 3 bars.

However, the printed-sized paper samples with a 3 bar had the highest print density due to the increase of coat weight. The coat weight did not have a significantly effect on print density values of printed-unsized and printed-sized sulfide paper samples unlike the printed-sized sulfide paper samples with a 3 bar.
