In addition, along with the progress and the development of science and technology of society, occur the functional fiber of a class in recent years, as contained the fiber of bamboo charcoal, contained the fiber of tourmaline (Tourmaline) etc.
As everyone knows; the largest organ of human body---skin; have many special functions, as have defencive function, sensory function, regulate body temperature, excretory function, absorption function, metabolic function, immunologic function, Gu this protection skin health also more and more causes people's attention.Thereby branch of industry and scientific worker abide by the development in science and technology of preventiveing treatment of disease very naturally and see diversion to the environment aspect of creating the protection skin health, optimizes people's quality of life, constantly carries out this piece of writing " surface " article of protection skin health.
Summary of the invention
The object of the present invention is to provide a kind of fiber that contains superfine calamine particle, because this fibrid has certain anticorrosion, anti-inflammatory properties to human body skin, so it also is a kind of functional fiber.After it is further processed into dress ornament, can optimize people's living environment, help the rehabilitation and the health care of dermatosis patient.The cotton fiber that contains superfine calamine particle in addition can also be directly as amenities, and it not only carries out anti-inflammatory and anticorrosion for the skin of trauma patient, but also for skin metabolism provides necessary zinc element, thereby healing acceleration.
Design of the present invention is such:
Select the raw material of Chinese medicine calamine (calamine after the calcining is a powder) as fibre modification, the peculiar function that has calamine through the fiber of modification, need calamine is carried out super-fine processing and surface treatment for this reason, calamine " is combined " well with fiber, form a kind of fiber that contains calamine ultrafine dust (nano_scale particle).
According to above-mentioned design, the present invention is achieved in that
At first calamine is carried out super-fine processing and surface treatment:
Experiment finds that calcining back its particle diameter of calamine powder is usually about 45 microns, when it is crushed to several microns, the calamine of this small particle has very strong agglomeration, calamine just is difficult to further pulverize in case reunite, so when super-fine processing, must be handled (or claiming surface modification) by surfactant, prevent the appearance of this agglomeration, make calamine by super-fine processing to 1.0~0.1 microns of particle diameters, and be dispersed in aqueous phase, form a kind of stable slurry.
Specific process is described below:
With commercially available particle diameter is that the calamine of 45 μ m places ball mill, press earlier 0.5~1.0% of calamine weight ratio and add surfactant, add entry again and be mixed with the mixture that solid content is 10~35% (wt), then the ball of making by aluminium oxide (or corundum) (sphere diameter 0.5~3.0mm) ball milling 24~48 hours; Taking-up is placed on along falling carries out hierarchical processing in the formula centrifugal classifying, with below standard component, promptly draw the outer ring of calamine particle from grader of particle diameter>1 μ m, returns and proceeds ball milling processing in the ball mill; Component up to standard, promptly the calamine slurry of particle diameter<1 μ m is drawn from the grader center, as intermediate products for next step use.Wherein said surfactant is to be a cationoid type surfactant of representative with the Si ion, or is a kind of among the class neutral surface active agent of representative with Si and Al ion, or their mixture.The maximum yield of the qualified products of classification gained is 60% (wt) of inventory (in calamine weight, together following).Experiment shows: the consumption of surfactant what, the yield of component up to standard is had bigger influence, be 0.2% o'clock as dosage of surfactant, under with same ball milling condition, the yield of the calamine that it is up to standard only is 20% (wt); When dosage of surfactant is 0.5% (wt), same ball milling 48 hours, the yield of calamine up to standard can reach 60% (wt), the visible surface activating agent is to the super-fine processing of calamine particle and be dispersed with bigger influence, if not having enough surfactants helps disperse, even the calamine particle that has been broken also can be agglomerated into bigger " particle " voluntarily, influence the yield of its certified products; When dosage of surfactant reached 1.0~1.5%, the dispersion thing can be more stable, but yield is constant substantially, so the consumption of surfactant suits with 0.5~1.0% (wt).
The length of ball milling time also has very big influence to the yield of product; When the ball milling time is 24 hours, even dosage of surfactant reaches 1.0%, its calamine product yield up to standard also only is about 30%.
As fully visible: the consumption of surfactant is 0.5~1.0%, the ball milling time be 48 hours be a kind of both economical suitable selection.If produce sector is ready to select the short ball milling time, as 24 hours, be to produce qualified slurry, but because below standard component proportion is bigger, more by the calamine material that returns reprocessing after the hierarchical processing, need expend more non-cutting time, all in all, economically may not be worthwhile.Secondly, with the calamine slurry of above-mentioned gained, with the active water dilution, making the content of calamine in the slurry after the dilution is 2~3% (wt), and it can be used as a kind of stable slurry for next step use (can be used as a kind of intermediate products supply the market).
Just contain the fiber preparation method of calamine ultrafine dust below, be described below respectively:
