<Experiment C：The tensile strength of core cladded sheet materials, breaking length>
By the use of square write by hand machine to having used NBKP, above-described embodiment 1 as general paper pulp (cellulose fibre) respectively
Cellulose fibre containing Cu ions and above-mentioned metal support the paper pulp (trade name Cellgaia (registrations of zeolite high density crystallization
Trade mark)) pulp material carry out copy paper and be made 18 ± 0.5g/m of weight per unit area2Sheet material 1~3.It should be noted that not
Addition paper power reinforcing agent.
NBKP, the cellulose fibre containing Cu ions are set to 100% and carry out copy paper by sheet material 1,2 respectively.In addition, sheet material 3 will
Metal supports zeolite high density crystallization paper pulp (trade name Cellgaia (registration mark)) and the match ratio of paper pulp (NBKP) sets
It is identical with comparative example 2 to carry out copy paper.
For resulting each sheet material, weight per unit area, thickness of paper, tensile strength are determined in the same manner as experiment B.By list
Position area weight and thickness of paper calculate density, and breaking length is calculated by weight per unit area and tensile strength.It should be noted that tension
Intensity is measured so that specimen width 25mm is wide, and breaking length is obtained by following formula.In addition, for sheet material 1, due to intensity
It is low, therefore 3 sheets measure tensile strength is overlapped, the tensile strength of every 1 is converted into divided by 3.Resulting result is shown
In table 4.
Breaking length (km)=tensile strength (kgf) × 1000/ { weight per unit area (g/m2) × specimen width (mm) }
【Table 4】
Can be clear and definite by table 4, sheet material 2 is higher than the intensity of sheet material 1.It is thought that due in the cellulose of metal ion
In the manufacturing process of fiber, the such effect of mashing treatment is played.Therefore, for by general paper pulp (NBKP etc.) and containing metal
Ion cellulose fibre mixing copy paper raw material carry out copy paper embodiment B1~B4 intensity turn into to general paper pulp
Carry out intensity equal during copy paper.
On the other hand, it is strong compared with sheet material 1 in the case of the sheet material 3 comprising 10wt% zeolite supporting fiber cellulose fibers
Degree reduces about 20%.It is thought that because, crystallization of zeolites in cellulose fibre, therefore fiber are expanded, hindering fiber
The flattening of cellulose fiber, interfibrous hydrogen bond is reduced.In addition, being additionally considered that because zeolite supporting fiber cellulose fiber is a large amount of comprising short fibre
Dimension composition.
