It forms the inhibition growth that can largely play to candida albicans and kills the effect removed, this is because nano copper particle and Bai Nianzhu
Bacterium can generate two kinds of extremely strong bactericidal effects when contacting.One is when nano copper particle surface touches candida albicans cell
" contact is killed " generated, exact mechanism not yet illustrates completely, but playing the role of mainly kill the reason of is white thought
Pearl bacterium cell generates by-product reactive oxygen species ROS in metabolism, and the candida albicans for being particularly in extreme environment can generate pole
A large amount of ROS, and ROS can cause the damage and death of candida albicans cell if accumulation excessively, and nano copper particle can
Fast and effeciently stimulation candida albicans cell generates a large amount of ROS, so that ROS content intracellular significantly rises, so as to cause white thought
The death of pearl bacterium.The second is since the Cup1 coding albumen in candida albicans can be with the copper in copper or copper alloy, Cu oxide
Ion combines, and copper ion has also assisted in the response to oxidative stress of candida albicans, can dramatically increase hydrogen peroxide-induced
Damage of the oxidative stress to candida albicans, it is similar when azole drug plays insect killing effect to candida albicans before generating drug resistance
The mechanism of generation, and realize that adaptability, thus a certain concentration can not be generated to it by encoding albumen to the Cup2 of copper ion susceptibility
Free copper ion can play it is good to candida albicans growth inhibition effect.And the Nanometer Copper to be precipitated in hollow structure
Grain cooperates the nano copper particle in micropore that can be formed along the cotton fibriia axial direction side that flax fiber is formed in conjunction with cotton fiber
To the thermally conductive cross-linked network of extension, the heating conduction of copper is much larger than flax fiber and cotton fiber, thus it is thermally conductive to be formed by copper
Cross-linked network determines the heating conduction of whole fiber, keeps its thermal conductivity in cotton fibriia section limited and greatly enhances
The cotton fibriia ability thermally conductive along its axial direction, realize cotton fibriia carried out in its axial one-dimensional angle it is good
One-way heat conduction.I.e. prepared by the cotton fibriia for linen-cotton socks, the heat that foot generates is after cotton fibriia initial absorption
It is unfavorable for conducting to sole part, but the one-dimensional square along fiber axial direction is unidirectionally conducted to the stocking leg, avoids sole temperature
Degree it is high and realize it is thermally conductive it is undesirable happen, and the stocking leg is usually in ankle or ankle upper end, relatively more open in one
In environment, it is easy diverging heat, similarly the high temperature heat of external environment such as asphalt road equally also can not be by by the cotton fibriia
The linen-cotton socks worked out are conducted to foot, are conducted in heat to the thermally conductive cross-linked network of nano copper particle, equally can be along cotton
One-way heat conduction is carried out in the axial direction of flaxen fiber to stocking leg part, and then can quickly and easily dissipate heat.
Preferably, the acid etching modification liquid is 55~60wt% methanesulfonic acid solution, saturation hypochlorite solution or full
