When people use conventional polyester-cotton textiles, due to the hydrophobicity of polyester fibers, the fabrics have low hygroscopicity and poor air permeability, and sweat ulcers cannot be discharged in a timely and effective manner. In addition, the static electricity generated by synthetic fibers will greatly reduce the wearing comfort. . During the wearing process, microorganisms generally exist on clothing fabrics. They can multiply rapidly under suitable conditions and cause fabrics stained with sweat and human secretions to produce a foul odor. In severe cases, they can also cause mildew and discoloration of the fabrics. . Although synthetic fiber cannot be degraded by microorganisms, its hygroscopicity is poor and its hygienic performance is even worse. The microorganisms retained on different types of fabrics are also different.
Clinical studies have pointed out that people who wear synthetic fiber socks are more likely to have foot infections than those who wear natural fiber socks, and interdigital ringworm cannot be washed from nylon socks inoculated with bacteria. Japanese scholars wore nylon, polypropylene, polyester, acrylic, pure cotton and wool socks for adult men and women for 1-2 months and found that bacteria were more common on polyester and polypropylene socks and less on wool and cotton socks. This shows that cotton and wool socks are very good at absorbing water-soluble pollutants such as sweat, while socks made of synthetic fibers have poor sweat-absorbing ability. The residual dirt on the skin surface combines with the high humidity and high temperature in the socks, and microorganisms Easy to breed. Research results show that many bacteria are still alive in commonly used dry cleaning agents (petroleum-based dry cleaning agents, perchlorethylene) and dry cleaning processes, on fabrics after dry cleaning and in dry cleaning agents without membrane filters in dry cleaning machines. A certain number of bacteria migrate from contaminated dirty clothes to clean clothes. Ordinary cold water washing is completely ineffective in removing harmful microorganisms, and methods such as bleaching and disinfection must be used.

It will bring the following adverse effects:

(1) Bacteria produce odor:

Clothes will produce odor, which is first caused by bacteria. Because bacteria metabolize, the products of metabolism produce sulfides or nitrogen compounds that emit odor. Bacterial excrement and human sweat can also produce odor due to chemical reactions. Therefore, half of the odor is caused by bacteria. If the bacteria are gone, the odor will be reduced by more than half. Another cause of smelly clothes is body odor. It can be seen that antibacterial can indeed remove part of the odor. Most of today’s products combine antibacterial and deodorizing functions for this reason. (2) Bacteria cause fading
The acid excreted by bacteria can cause fading and discoloration of dyed fabrics, which is another hazard caused by bacteria to textiles. Therefore, antibacterial finishing of textiles is not only for health, but also for the maintenance of clothing. It seems that antibacterial has become a function that fiber materials must have, not just an additional performance.
In summary, solving the hygroscopicity and increasing the antibacterial function of polyester-cotton fabrics are important ways to improve their wearing performance.
