In Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 a, Fig. 5 b, the base material 5 of the drenched wet film 4 of sense consists of cellulosic material, and to be paper pulp, staple fibre or paper pulp copy any number of in thing (carry out copy paper after raw material is mixed and obtain material) with staple fibre mixed.And regenerated cellulose 6 is held on the cellulosic material of base material 5.In addition, base material open space 5a is as the cellulosic fiber of base material 5 and the peristome between fiber.To cover the form of this base material open space 5a, keep regenerated cellulose 6.
In addition, nonwoven 7 has than the shear strength of the drenched wet film semi-finals of sense and with the form of the drenched wet film 4 of stacked sense and arranges.The in the situation that of present embodiment, the drenched wet film 4 of sense is to be undertaken stacked by the state of 2 pieces of nonwoven, 7 clampings.In addition, the drenched wet device 8 of sense forms to fix the form of the surrounding of the nonwoven 7 of feeling drenched wet film 4 and being laminated in the drenched wet film 4 of sense with framework 9.In addition, in a part for fruit and vegetable box main body 2, be provided with peristome, and with the form with framework 9 airtight its peristomes, the drenched wet device 8 of sense be set.In addition, fruit and vegetable box main body 2 is provided with and can preserves fruits and vegetables Deng space.
In addition, in fruit and vegetable box main body 2, configure fruit and vegetable box lid 3, and be provided with peristome in a part for fruit and vegetable box lid 3, also can be to come the form of the drenched wet device 8 of airtight sense to be configured with respect to its peristome.
First, for the effect that forms the regenerated cellulose of the drenched wet film 4 of sense, describe.
Common so-called cellulose is divided into naturally occurring cellulose and the large class of regenerated cellulose two.
First, cellulose is the carbohydrate polysaccharide of chemical formulation (in the Fig. 9 with) of the crystal structure that comprises in natural plant cell wall, and reduction end towards on be identical parallel chain structure in adopting crystallization.This parallel chain structure exists as trickle fiber, and is called as microfibre (microfibril) (the set unit of filamentary fibers element molecule).The cellulose of this microfibre state produces hydrogen bond and becomes firmly hydrogen bond aggregate (crystal region) in the situation that long macromolecule is fitly gathered between cellulosic molecule.Therefore, become the state that moisture between molecule can not enter (being difficult to enter), thus, no matter because humidity can continue to obtain identical crystal structure, thus moisture no matter high humility or low humidity be all difficult to by.
Yet the regenerated cellulose 6 that forms the drenched wet film of sense of the present invention is using viscose fiber as raw material biochemical cellulose and be the carbohydrate (polysaccharide) being represented by Fig. 9 again.Therefore, relative for directly applying flexibly the situation of natural material with cellulose, regenerated cellulose be by cellulose with after naoh treatment, add carbon disulfide and obtain viscose fiber (sodium cellulose xanthate sodium cellulose xanthate), thereby this viscose fiber is carried out to the regenerated cellulose that acid treatment returns to cellulose state again.Therefore, regenerated cellulose is the crystal structure collapse as cellulose feature, exist in a large number adjacency strand non-reduced end towards different antiparallel chain structures, i.e. noncrystalline structure.
Noncrystalline characteristic of this regenerated cellulose, because cellulosic molecule is not Hydrogenbond or part Hydrogenbond, is difficult to enter into the state between cellulosic molecule so become airborne moisture under drying regime when low humidity.In addition, when high humility, in aerial washy situation, become moisture and easily enter into the state between cellulosic molecule.Its result becomes swelling state, and airborne moisture (moisture) can move with the form of escaping, and the mobile quantitative change of moisture is many.By such characteristic, regenerated cellulose has along with humidity uprises and humidity and vapor transfer rate by regenerated cellulose becomes many character, the i.e. feature of so-called hygroreception.
By the characteristic of the above such regenerated cellulose, the drenched wet film 4 of sense has along with humidity uprises and the many characteristics of vapor transfer rate change.
The drenched wet film 4 of sense is by being made as 0.3～1.0g/cm by the density of base material 5
3, and further with respect to the area of described base material 5, the amount of regenerated cellulose 6 is made as to 0.3～3.0g/m
2thereby the thoroughly rate of change of wet ability in its high humidity regions (humidity is 90～95%Rh region) can be about 5 times of rate of change of the thoroughly wet ability in low humidity region (humidity is 10～50%Rh region).
Have, the regenerated cellulose of the drenched wet film 4 of sense of the present invention is by base material 5 being carried out to coating or the dipping of 20～50% viscose fiber again, then carries out acid treatment and cured fiber element remain on base material 5 and form.If in the situation that viscose fiber concentration is less than 20%, as the gap of fiber and the fiber of base material 5, the amount of the regenerated cellulose of base material open space 5a is because become and be difficult to form cellulose membrane less.Have again, in the situation that viscose fiber concentration surpasses 50%, so because the high viscose fiber of viscosity can not enter in the base material open space 5a as the fiber of base material 5 and the gap of fiber equably, thereby have the situation that is difficult to form the situation of cellulose membrane and has generation spot.
Its result is, in the situation that be stored in fruits and vegetables in fruit and vegetable box 1, for a small amount of, preserve or after just taking out a part of fruits and vegetables etc., when the humidity of fruit and vegetable box 1 inside occurs to reduce, the amount that moisture discharges from fruit and vegetable box due to the effect of the drenched film 4 of sense is because be trace, so be substantially closed in fruit and vegetable box.In addition, in the situation that the fruits and vegetables amount in fruit and vegetable box 1 of being stored in is large or long-time preserve etc., in the situation that the inner space of fruit and vegetable box 1 becomes high humility state, if the amount of moisture that the drenched wet film 4 of sense discharges from fruit and vegetable box is micro-state, can make moisture generation dewfall, by occurred dewfall, will be made the fruits and vegetables generation web rot that must preserve, but can make humidity transit dose increase by feeling the effect of drenched wet film 4, in fruit and vegetable box 1, can there is not dewfall, and fruits and vegetables can be remained on not can web rot fresh state.
Have again, as the means that viscose fiber soaked into for base material 5, have the method that viscose fiber is applied or flooded.Coating refers to the surface that viscose fiber is coated on to base material 5, and dipping refers to base material is immersed in viscose fiber.This coating method is because only make regenerated cellulose be held in the surface of base material 5, so preferably adopt the method that viscose fiber can be impregnated into the dipping of base material 5 inside.
Having, is object so that viscose fiber is impregnated into base material 5 inner again, after preferably viscose fiber being applied or flooding, with mechanical roller pressuring machine from exerting pressure up and down so that the state of viscose fiber in impregnation.
Have again, make after viscose fiber is impregnated in base material 5, as regenerated cellulose 6 being held in to the means of base material 5, with sulfuric acid solution, carry out acid treatment and to synthesize macromolecular fibre shape by the viscose fiber processing of regenerating, thereby at the base material open space 5a of base material 5, regenerated cellulose 6 is solidified, so because these means can to improve base material 5 preferred with the close attachment intensity of regenerated cellulose.
Then, the poisture-penetrability of the drenched wet film of the sense of the present invention obtaining by above-described method is described.
Fig. 5 a means the chart of the drenched regenerated cellulose amount of wet film of the related sense of embodiments of the present invention 1 and the humidity interdependence of water vapour permeability, and Fig. 5 b means the chart of the drenched serviceability temperature of wet film of the related sense of embodiments of the present invention 1 and the humidity interdependence of water vapour permeability.
The water vapour permeability of the drenched wet film 4 of sense is described with Fig. 5 a and Fig. 5 b.
In addition, water vapour permeability represents as humidity transit dose in these figure.This humidity transit dose refers to the amount of stipulating by the moisture weight of the drenched wet film 4 of sense of per unit area as time per unit.
From Fig. 5 a, the drenched wet film 4 of sense just has along with humidity rises the tendency that humidity transit dose increases gradually.At this, observe the density 0.3～1.0g/cm with respect to base material 5
3keep the humidity transit dose of the drenched wet film 4 of sense of regenerated cellulose known, the recruitment of the humidity transit dose in the time of humidity from 90% to 95% rising 5% is compared with from 50% to 90% rising 40% time, large 2～10 times.That is, under 90% high humility state, humidity transit dose sharply rises.This phenomenon is to result from the cellulosic molecule of the regenerated cellulose that describes in embodiment 1 beginning to be configured to noncrystalline structure, its reason is that airborne moisture can not enter between the cellulosic molecule of noncrystalline structure under the state of low humidity, under the state of high humility, because airborne moisture enters into, makes between molecule swelling and moisture become easily to see through between cellulosic molecule.
Then, Fig. 5 b confirms the drenched different result of wet film 4 performances of the sense being caused by temperature.
From Fig. 5 b, if during than lower temperature when (5 ℃) and high temperature (23 ℃), humidity transit dose globality step-down during low temperature.The cause that the translational speed of the airborne moisture of temperature step-down diminishes so this can consider.
Just as described above, if regenerated cellulose is held in the situation of the drenched wet film 4 of sense of base material 5, can confirm to bring into play water vapour permeability, the thoroughly rate of change of wet ability in high humidity regions (humidity is 90～95%Rh region) becomes about 5 times of thoroughly wet ability in low humidity region (humidity is 10～50%Rh region).
Have again, in above manufacture method, if be pre-mixed mould inhibitor for viscose fiber, without the adhesive that uses mould inhibitor to use in the drenched wet film 4 of the final sense forming etc., and can keep regenerated cellulose with the state that contains mould inhibitor, can be because adhesive causes feeling the infringement of drenched wet performance, thereby preferably.
In addition, as mould inhibitor, even from selecting strong basicity due to viscose fiber also to undergo no deterioration and being insoluble in the viewpoint of the material of water, have the mineral-type mould inhibitors such as TBZ, silver, copper, zinc; The organic mould inhibitors such as triazine, Isoprothiolane, iprodione, thiabendazole, wherein, from the viewpoint being widely used as food additives, cheap, anti-mold effect is lasting, are preferably used TBZ.
