Background
Wood fiber is a mechanical tissue composed of thickened cell walls and fibrous cells having fine crevice-like pores, which are lignified, and is one of the main components constituting xylem. The wood fiber used in the textile and clothing industry is viscose fiber which is converted from wood pulp through a production process and is cellulose fiber.
The wood fiber is divided into two parts of rough processing and finish processing, wherein the rough processing is to process wood into wood fiber in a sawdust shape, and the finish processing is to further process and extract the wood fiber prepared by the rough processing and can be applied to other produced wood fibers.
The traditional wood fiber rough processing production process generally comprises cleaning, high-temperature cooking and grinding, and in the wood fiber production process, wood is softened by using high-temperature cooking, so that the subsequent grinding of the wood is facilitated. However, high-temperature cooking generally requires a cooking box with large energy consumption, and in order to meet production requirements, the size and the volume of the cooking box need to be designed into large specifications, so that the energy consumption in the wood fiber processing process is large, and the production cost of enterprises is greatly increased.

and grinding, namely grinding the dried wood into wood fibers.
According to an embodiment of the present invention, the energy saving wood fiber preparation method further comprises: a packaging step, wherein the packaging step comprises: and (4) pressing and packaging the wood fiber.
According to an embodiment of the present invention, the energy saving wood fiber preparation method further comprises: a perforating step located between the cutting step and the fermentation softening step, the perforating step comprising: the sheet-like wood is punctured so that evenly distributed perforations are formed in the wood.
According to an embodiment of the present invention, the energy saving wood fiber preparation method further comprises: a pre-crushing step between the cutting step and the fermentation softening step, the pre-crushing step comprising: the wolf tooth roller rolls the sheet wood, so that pits which are uniformly distributed are formed on the wood.
According to an embodiment of the present invention, the fermentation softening step further comprises: spraying white vinegar on the flaky wood.
The energy-saving wood fiber preparation method disclosed by the invention has the advantages that the traditional high-temperature cooking softening processing mode is replaced by the fermentation softening mode in the production process, the production energy consumption is greatly reduced, and the production cost of enterprises is reduced.
Drawings
FIG. 1 is a flow chart of the method for preparing energy-saving wood fiber according to the present invention.
Detailed Description
The energy-saving wood fiber preparation method of the present invention will be described in further detail with reference to the following specific examples and accompanying drawings.
Please refer to fig. 1.
The invention provides a preparation method of energy-saving wood fiber, which is mainly used for roughly processing wood fiber.
And (3) cleaning, namely cleaning the wood, removing impurities on the wood and ensuring the purity rate of the wood fiber produced subsequently. In the present application, the wood used is subjected to a peeling treatment in advance, and specifically, pine, eucalyptus, or the like can be used as the wood.
And cutting, namely cutting the wood into sheets by an automatic cutting machine.
And (3) fermenting and softening, namely placing the flaky wood in a fermentation bin, and fermenting and softening the flaky wood by using yeast, wherein the fermentation time is 1-3 days, the fermentation temperature is kept at 27-32 ℃, and the yeast can be attached to the wood in a spraying manner. Wherein, the single wood is sprayed with independent yeast, which can effectively ensure the uniformity of the yeast attached on the wood. Of course, yeast attachment to wood can also be achieved by smearing.
And (4) secondary cleaning, namely taking out the fermented and softened sheet wood and cleaning with clear water.
And drying, namely drying the wood subjected to secondary cleaning to dry the surface of the wood.
And grinding, namely grinding the cleaned wood by using a grinder, and grinding the wood into wood fibers.
In the application, the energy-saving wood fiber preparation method further comprises a packing step, wherein the packing step comprises the step of pressing and packing the wood fibers, so that the wood fibers are blocky, the occupied space is reduced, and the stacking storage and the transportation of the wood fibers are facilitated.
In an embodiment, in order to accelerate the fermentation and softening of the wood, the energy-saving wood fiber preparation method further comprises a perforation step between the cutting step and the fermentation and softening step, specifically, the perforation step comprises perforating the sheet-shaped wood, for example, an automatic perforating machine is used for pressing the wood, so that evenly distributed perforations are formed on the wood, the contact area between the wood and the yeast is increased through the perforation, and the fermentation and softening speed of the wood is further increased.
In another embodiment, the energy-saving wood fiber preparation method further comprises a pre-crushing step between the cutting step and the fermentation softening step, specifically, the pre-crushing step comprises rolling the sheet wood through a wolf tooth roller, so that pits are uniformly distributed on the wood, the surface area of the wood is increased by using the pits, meanwhile, the surface of the wood is damaged, the yeast is conveniently infiltrated and damaged, and the fermentation rate is effectively improved.
In the fermentation softening step, after the flaky wood in the fermentation bin is sprayed or coated with the yeast, air is blown into the fermentation bin at irregular time, for example, the air is blown at intervals of 3 hours in sequence, so that the yeast can float in the fermentation bin, and the uniformity of the yeast attached to the wood is further improved.
In another embodiment, the fermentation softening step further comprises spraying white vinegar on the flaky wood, and catalyzing the yeast by using active enzyme contained in the white vinegar, so that the fermentation speed of the yeast is greatly increased.
In conclusion, the energy-saving wood fiber preparation method disclosed by the invention has the advantages that the traditional processing mode of high-temperature cooking softening is replaced by a fermentation softening mode in the production process, the production energy consumption is greatly reduced, and the production cost of enterprises is reduced.
While the invention has been described in conjunction with the specific embodiments set forth above, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, all such alternatives, modifications, and variations are intended to be included within the spirit and scope of the present invention.
