Technical Field
The application relates to the field of fabrics, in particular to an antibacterial and antistatic fabric and a preparation method thereof.
Background
Static electricity, which is a static or non-flowing charge, is formed when the charge accumulates on an object or surface. For example, when the chemical fiber clothes rub the human body in winter and the weather is dry, the human body can feel the electric shock needle-prick feeling, which is a bad place of static electricity.
Moreover, the persistent static electricity can cause the pH value of the blood of a human body to be increased, the excretion amount of calcium in urine to be increased, and the blood calcium to be reduced, thereby having adverse effects on the heart, the brain and the skin of the human body.
In recent years, many people have studied antistatic fabrics, and finally, the reason that the antistatic effect of the fabrics can be improved by enhancing the moisture absorption performance of the fabrics is that the static leakage amount of the fabrics is improved after the fabrics absorb moisture in the environment.
However, after the moisture absorption performance of the fabric is enhanced, the fabric is in a relatively humid environment in an environment with high humidity, and the environment is suitable for bacteria growth, so that the fabric is easy to breed bacteria. However, the fabric after breeding bacteria is easy to generate some peculiar smell, and bacterial plaque is easy to form on the fabric when serious, thereby influencing the use of people.
