Description
Technical field
The invention belongs to pulping and paper-making fields, and in particular to a method of improve bamboo pulp fiber pliability.
Technical background
With bamboo pulp in field of tissue paper using more and more extensive, requirement of the people to bamboo pulp fiber pliability also by
Gradually improve.The advantages of bamboo pulp be protect trees, reproducibility is strong, resource is sufficient, be suitble to middle and high end paper of manufacturing paper with pulp；The deficiency of bamboo pulp is fine
Dimension itself is more stiff, therefore it is extremely important to improve bamboo pulp fiber pliability.Traditional raising pliability method is using softness
Agent, but softening agent is not degradable and has certain injury to the body of people.Accordingly it is desirable to find a kind of substitution softening agent
It is environmentally protective, easy to operate, low-cost raising bamboo pulp fiber pliability method.
Summary of the invention
The purpose of the present invention is overcome the deficiencies of the prior art and provide a kind of method for improving bamboo pulp fiber pliability.
Technical method of the invention is summarized as follows：
A method of bamboo pulp fiber pliability is improved, is included the following steps：
Step 1：By bamboo pulp fiber raw material pulping to beating degree be 25 ° of SR-35 ° of SR or carry out disappear it is latent discongest, obtain fiber
Slurry；
Step 2：The mass concentration for adding water to adjust bamboo pulp maintains the temperature at the slurry after dilution to 0.5wt%-10wt%
20 DEG C -40 DEG C, it is passed through ozone；It is 2gh by setting ozone flow-1-5g·h-1, ozone usage 0.1%-2%；
Step 3：The material that step (2) obtain is squeezed out into moisture, measures fiber bending degree with glass-metal silk method to determine
The method of amount analysis fiber flexibility measures the pliability of single bamboo pulp fiber；
Fibre stuff maintains temperature at 30 DEG C.
Ozone flow is 3gh-1。
The mass concentration of fibre stuff is 2%.
Ozone usage is most preferably 0.75%.
The present invention uses ozone treatment bamboo pulp fiber, and one side ozone can go out wood from fiber surface and space between cells
Quality and part hemicellulose, on the other hand, fibre bundle no longer bundle, and fiber becomes loosely, and softness is improved.This hair
It is bright to provide a kind of low in cost, the method for the raising bamboo pulp fiber softness being simple and efficient, with vast potential for future development.
Specific embodiment
Following case study on implementation be in order to enable those skilled in the art to more fully understand the present invention, but not with appoint
Where formula limitation is of the invention.
Embodiment 1：A method of bamboo pulp fiber pliability being improved using ozone treatment, is included the following steps：
Step 1：It is 31 ° of SR by bamboo pulp fiber raw material pulping to beating degree, obtains fibre stuff；
Step 2：The quality bamboo pulp fiber slurries such as five parts are taken, water is added to adjust the mass concentrations of this five parts of fibre stufves to 3%,
This five parts of slurries are put into water-bath and adjust the temperature to 30 DEG C.It is respectively 3gh in ozone flow-1Under conditions of be passed through 0,
0.25%, 0.5%, 0.75%, 1% ozone amount.
Step 3：The material that step 2 obtains is squeezed and removes moisture, measures fiber bending degree with glass-metal silk method to quantify
The method for analyzing fiber flexibility measures single bamboo pulp fiber pliability.It is shown in Table 1.
Table 1 starches influence of dense ozone usage when being 3% to bamboo pulp fiber pliability
Embodiment 2：A method of bamboo pulp fiber pliability being improved using ozone treatment, is included the following steps：
Step 1：It is 31 ° of SR by bamboo pulp fiber raw material pulping to beating degree, obtains fibre stuff；
Step 2：Take the quality bamboo pulp fiber slurries such as five parts, respectively plus water adjust the mass concentrations of this five parts of fibre stufves to
1%, 2%, 3%, 4%, 5%, this five parts of slurries are put into water-bath and adjust the temperature to 30 DEG C.It is 3gh in ozone flow-1's
Under the conditions of be passed through 0.75% ozone amount.
Step 3：The material that step 2 obtains is squeezed and removes moisture, measures fiber bending degree with glass-metal silk method to quantify
The method for analyzing fiber flexibility measures single bamboo pulp fiber pliability.It is shown in Table 2.
The dense influence to bamboo pulp fiber pliability is starched when 2 ozone usage 0.75% of table
Claims (5)
1. a kind of method for improving bamboo pulp fiber pliability, it is characterized in that including the following steps：
Step 1：It is 25 ° of SR-35 ° of SR by bamboo pulp fiber raw material pulping to beating degree, obtains fibre stuff；
Step 2：Slurry after dilution is maintained the temperature at 20 to 0.5wt%-10wt% by the mass concentration for adding water to adjust bamboo pulp
DEG C -40 DEG C, it is passed through ozone；It is 2gh by setting ozone flow-1-5g·h-1, ozone usage 0.1%-2%；
Step 3：The material that step 1 is obtained squeezes out moisture, with glass-metal silk method measurement fiber bending degree come quantitative analysis
The method of fiber flexibility measures the pliability of single bamboo pulp fiber.
2. according to the method described in claim 1, it is characterized in that the beating degree is 31 ° of SR.
3. according to the method described in claim 1, it is characterized in that the fibrous raw material is bamboo pulp.
4. according to the method described in claim 1, it is characterized in that the slurry concentration is in 1%-5%.
