Antibacterial moisture wicking finishing of polyester/cotton blended fabric
Polyester-cotton fabrics (fabrics) are treated with moisture-wicking, antibacterial and deodorant finishing, which fundamentally improves the comfort performance and hygienic conditions of the traditional product of polyester-cotton blended fabrics (fabrics). This article provides a detailed description of the principles, processes, and testing methods of finishing processing.
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. As we all know: 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, but 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 dispersion speed will also be slower, causing the human body to feel cold and wet. As an important part of the fabric, polyester/cotton blended fabrics need to maintain their smooth feel, good wrinkle resistance, excellent strength and dimensional stability, and easy washing and quick drying, while overcoming 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 fabric quality have become issues of concern to everyone. To this end, we use Beijing Jieershuanggao’s moisture-wicking finishing agent SW and antibacterial finishing agent SCJ-891 to change the performance of polyester/cotton blended fabrics by focusing on the moisture absorption comfort and antibacterial and deodorizing properties of the fabric, so that it can achieve good results. Comfortable and breathable, and added antibacterial and antistatic functions, improving the quality of the fabric.
1. The necessity of antibacterial and moisture-wicking finishing of polyester-cotton fabrics
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 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. 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 away 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 have good absorbency to sweat and other water-soluble pollutants, while socks made of synthetic fibers have poor sweat absorption 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 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.
The production of bacteria will bring the following adverse effects:
(1) Bacteria produce odor:
Clothing smells, first of all, caused by bacteria. Because bacteria metabolize, the products of metabolism produce sulfides or nitrogen compounds that cause 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. uOPPx5oI
