As people’s living standards improve, clothing becomes more and more sophisticated. People’s requirements for clothing are no longer just changes in styles and colors. People have increasingly higher requirements for the comfort, health, safety and environmental protection of clothing fabrics.

Polyester fiber has low water absorption and poor moisture permeability. Due to its accumulation of static electricity, it is easy to cause entanglement when wearing, especially when moving, it is easy to feel stuffy;

Pure cotton fiber has good hygroscopicity and is comfortable to wear. However, when a person sweats a lot, the cotton fiber will swell due to adsorption and mixing, and its air permeability will decrease and it will stick to the skin. At the same time, the water dissipation speed is also slow. This causes the human body to feel cold and wet.

As an important part of the fabric, polyester/cotton blended fabric maintains its smooth feel, good wrinkle resistance, excellent strength and dimensional stability, and is easy to wash and quick-dry. It overcomes the shortcomings of the polyester fabric itself, such as its unique hydrophobicity. As a result, the fabric has low hygroscopicity and poor air permeability, and sweat stains cause bacterial breeding, affecting people’s health and other shortcomings.

Improving these shortcomings of polyester/cotton blended fabrics and improving the quality of fabrics have become a common concern.

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 stains cannot be discharged in a timely and effective manner. In addition, the static electricity generated by synthetic fibers will also 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 (recommended: FCK002 is moisture-wicking and easy to remove contamination. Finishing, FCK344 antibacterial and anti-mite finishing agent

), in severe cases, it will cause mildew and discoloration of the fabric. 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.

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 away from nylon socks that are inoculated with bacteria. Experiments have found that when nylon, polypropylene, polyester, acrylic, pure cotton and wool socks are worn by adult men and women for 1-2 months, it is found that bacteria are 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, and the remaining dirt on the skin surface isThe combination of high humidity and high temperature in the house makes it easy for microorganisms to multiply.

Commonly used dry cleaning agents (petroleum dry cleaning agents, perchlorethylene) and dry cleaning processes, many bacteria are still alive 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.
