1. The mechanisms of textile antibacterial finishing
The antibacterial finishing of textile is based on three mechanisms: controlled release, regenerative principle, barrier or blocking effect.
1.1  Controlled release: the fabric with antibacterial finishing can release antibacterial agent at certain temperature and humidity, it’s speed can kill or restrain the growth of the bacteria or fungi.
1.2 Regenerative principle: the fabric with special antibacterial finishing under the washing or radiation, the agent on the fabric and the covalent bond fiber fracture and constantly produce bactericide, so as to achieve the anti-microbial purpose.
1.3 Barrier or blocking effect: through the inert physical barrier layer or coating formed on the fabric, to stop the microorganism across the fabric; or coating direct contact surface active membrane on the fabric, when the bacterial contact with the antibacterial finishing agent, through absorptive action to destroy the metabolism of cell, prevent the growth of bacteria.
2. From the point of bacteriology, the antibacterial finishing agent can achieve the purpose of bacteriostatic or sterilization via the following routes:
2.1 React with proteins in bacterial cells, undermine its function.
2.2 Deactivate various metabolisms in bacterial cells, so as to kill bacteria. 
2.3 Control the production of the spore, impede the synthesis of DNA, inhibit its growth.
2.4 Abuse the energy release system in cells.
2.5 Faster oxidative phosphorylation redox system, upset the cells normal growth system.
2.6 Through the absorptive action of charge, makes the bacterial cells broken, so as to kill bacteria. 
2.7 Hinder the growth of the electron transfer system and the amino acid transamination.
