Copper Ion Antibacterial Raw White: Unveiling a Cutting-Edge Innovation in Textile Technology.

Summary

Health care-associated infections (HAIs) are a global problem associated with significant morbidity and mortality. Controlling the spread of antimicrobial-resistant bacteria is a major public health challenge, and antimicrobial resistance has become one of the most important global problems in current times.[1] The antimicrobial effect of copper has been known for centuries, Copper's antibacterial properties have been known for centuries and are used in clothing and medicine.

As we all know, copper comes in many colors:

If you look at the image above, there are 4 different colours and 5 different element/compounds.

A – Copper metal. Copper metal is a reddish brown solid.
B – Copper(II) carbonate is a green solid/powder.
C – Copper(II) sulfate/nitrate/chloride. These compounds can exist as blue solutions or crystals
D – Copper(II) oxide is a black solid.
E – Copper(II) hydroxide is a blue precipitate.[2]

So the problem is that yarns made of copper ions have their own copper color.

How to solve this problem?

Principle: 

Copper ion antibacterial yarn is produced by adding nanometer copper ions through special crafts in the spinning process. Research found that most of the copper compounds are soluble, thus the copper ions entering the human body are also dissolved and can be easily excreted by metabolism. Therefore the yarn products made of copper ions have been loved by customers.

The exact role of antibacterial material is to maintain the balance of bacterial flora. It plays the role of peacemaker, killing and inhibiting those strains that break the balance of the original flora, and restoring the environment to its proper state.

But Hangzhou Yongxing Chemical Fiber Co., LTD., a company specializing in the research and development of polyester chemical fiber for more than 20 years, they developed a white copper antibacterial polyester.

The white antibacterial polyester is more convenient for dyeing. As soon as it came out, it received a lot of attention

Product overview:

Antibacterial material, a new functional material with the function of killing or inhibiting microorganisms. It belongs to antibacterial fiber, which is functional fiber, playing an important role in antibacterial textile. Metal copper ionic antibacterial polyester has developed rapidly in recent years, it has the characteristics of high safety, no chemical resistance, especially its excellent heat resistance and chemical stability, and has been widely used in fiber and other fields.In addition, white is easier to dye, so it is also more popular.

Downstream products: 

Suitable for different kinds of underwear, socks, bedding, home cloth, decorative cloth, sanitary dressing, hospital sheets, surgical gowns, doctor overalls, patient gowns, food industry special clothing, shoe materials, gloves and various antibacterial clothing.(The earliest use of copper fiber is European and American countries)
