Enzyme material.Meanwhile, a small amount of lignin that high temperature, high alkalinity solution can be completed further to cotton stalk bark fibre for hydrolysis etc.
Impurity is hydrolyzed again.Then slow reduction water temperature and pH value, are able to carry out suitably cold to cotton stalk bark fibre
But, the acid-base property on control cotton stalk bark fibre surface, lifts the pliability of cotton stalk bark fibre.
Bleaching can not only remove the natural pigment contained in cotton stalk bark fibre, assign the necessary whiteness of fiber, lift it
Aesthetics.The other impurities remained on cotton stalk fiber are further removed simultaneously and cotton stalk bark fibre is lifted to a certain extent
Wet performance.Specifically, bleaching is placed on the cotton stalk bark fibre of degumming in the water-bath that temperature is 90-120 DEG C so that water
The cotton stalk bark fibre of the superiors is covered, it is 30-40% hydrogen peroxide then to add with mass percent, and is incubated 1-2 hours, its
In, the amount of the hydrogen peroxide of addition is the 1/20-1/30 of total water.Cotton stalk bark fibre after colour fading is rinsed into 2-3 using water
It is secondary, remove the hydrogen peroxide that cotton stalk bark fibre surface may be adhered to.
Because the fabric hand after bleaching is endured with all one's will, and most of is fibre bundle, and the technique being unfavorable for below is carried out, so needing
By fiber softening.The grease that cotton stalk bark fibre is lost in degumming and bleaching process can be supplemented while softening, cotton is lifted
The feel of bar hide fiber.Specifically, softening is in 80-120 DEG C of water-bath, to make by the cotton stalk bark fibre after bleaching in temperature
The cotton stalk bark fibre that water covers the superiors is obtained, is then added and softening agent, and is incubated 3-5 hours, wherein, the softening agent of addition
Measure as the 1/7-1/12 of total water.It is further preferred that the softening agent used is that amphoteric softening agent and cationic are soft
The mixture of agent, both can lift the softness of softening agent at synergy, meanwhile, it is capable to prevent cotton stalk fiber turn yellow or
Discoloration.Cotton stalk bark fibre after softening is rinsed 2-3 times using water, the softening agent that cotton stalk bark fibre surface may be adhered to is removed.
Finally that the Heating Steel Wire of cotton stalk bark fibre tiling to drying baker is online, fiber will spread thin and uniform as far as possible, will
Baking oven is heated to 80-120 DEG C and dried 5-8 hours.
The present invention also provides a kind of cotton stalk bark fibre preparation technology, and it includes above-mentioned cotton stalk handling process.Using above-mentioned
Cotton stalk handling process quickly can handle the cotton stalk bark fibre refined to cotton stalk progress, meanwhile, the cotton stalk bark fibre structure
Completely, surface is submissive and does not contain other impurities.
A kind of cotton stalk handling process that the present invention is provided utilize complex enzyme specific effect, can be quickly and efficiently general
The impurity such as colloid, lignin, the cellulose on cotton stalk bark fibre surface dissolve and removed.Degumming process liquid used at the same time for wait from
Daughter state, plasma has high-energy, rapidly can contact and react with impurity, further, accelerate molten
The efficiency and speed of solution.And after the completion of washing remove degumming process liquid and dissolved impurity, further ensure cotton stalk bark fine
The quality of dimension.The pigment in bleaching removal cotton stalk bark fibre is then carried out to cotton stalk bark fibre, the sense organ of cotton stalk bark fibre is lifted
Degree, meanwhile, increase the wettability of cotton stalk bark fibre, then cause cotton stalk bark fibre soft by softening again so that cotton stalk bark is fine
Dimension more can be smooth.Drying removes the moisture of cotton stalk bark fibre.
The feature and performance to the present invention are described in further detail with reference to embodiments.

Dissolved impurity, further ensures the quality of cotton stalk bark fibre.Bleaching is then carried out to cotton stalk bark fibre and removes cotton stalk bark fibre
Pigment in dimension, lifts the sense organ degree of cotton stalk bark fibre, meanwhile, increase the wettability of cotton stalk bark fibre, then again by softening
So that cotton stalk bark fibre is soft so that cotton stalk bark fibre more can be smooth.Drying removes the moisture of cotton stalk bark fibre.Prepare
Cotton stalk bark fibre structural integrity, surface is smooth, with certain pliability.
Embodiments described above is a part of embodiment of the invention, rather than whole embodiments.The reality of the present invention
The detailed description for applying example is not intended to limit the scope of claimed invention, but is merely representative of the selected implementation of the present invention
Example.Based on the embodiment in the present invention, what those of ordinary skill in the art were obtained under the premise of creative work is not made
Every other embodiment, belongs to the scope of protection of the invention.
