The Necessity of Antibacterial and Mouldproof Fabric.
There are many microorganisms on the surface of human skin, some of which are beneficial bacteria for the human body, while others are pathogenic bacteria.
These microorganisms obtain nutrients from human secretions, sweat, and shedding skin, and undergo metabolism processes of growth, reproduction, and death. At the same time, because the fatty acids and lactic acid in sweat and secretions can kill a variety of microorganisms, and the mutual killing and inactivation of microorganisms form their balance and coordination in quantity, which generally does not cause harm to the human body.
However, once this balance is disrupted, causing bacterial imbalance, a small amount of pathogenic bacteria will multiply rapidly and cause harm to human health through the skin, respiratory tract, digestive tract, and mucous membranes of the reproductive tract.
Bacteria, fungi, and dust mites can cause serious damage and cause many different problems. They can produce odors in underwear and sportswear, breed extensively in medical environments, cause allergic reactions, and may cause stains on indoor furnishings and other household items.
Microbial growth can also erode outdoor textiles, such as awnings, tents, or lawn furniture, and cause discoloration and degradation.
Mold is a type of fungus that can be found in almost any environment, including the air.
There are many different types of mold, and "black mold" usually refers to a type called Stachybotrys chartarum. Other common types include Alternaria, Aureobasidium, and Chaetomium.
It is important to note that mold in its early stages produces a musty odor and can be easily removed from surfaces, but mold growth indicates that the fungus has matured and become more difficult to remove.
Fungi reproduce through spores and can proliferate on surfaces that are moist and rich in fibers, such as fiberboard, wood, gypsum board, and plasterboard, as well as in areas with small amounts of seepage or water leaks.
Harmful Effects of Mold
When black Aspergillus grows on fabrics, its spore masses appear black, causing the fibers to turn black, while Penicillium is yellow, and green mold is green. The branching spore fungus is brown, and so on.
During their metabolic processes, molds and bacteria produce ethylene glycol, citric acid, oxalic acid, lactic acid, acetic acid, and so on, resulting in unpleasant or peculiar odors, increased fabric temperature, reduced luster, the appearance of mold spots, and potential harm to human health through skin contact or the respiratory system.
Black mold can produce toxins. It releases so-called mycotoxins, which are highly harmful to building residents. Of course, some people are more sensitive to fungal spores than others and may develop respiratory syndrome after inhaling small amounts of spores.
However, a place with a large amount of mold toxins can even cause fungal poisoning in healthy individuals, depending on the concentration of mycotoxins, the length of exposure to the toxins, and other factors.
Exposure to fungi is more harmful for infants and young children. Research suggests that children exposed to mold may be more susceptible to developing asthma. In 2009, the World Health Organization released "WHO Guidelines for Indoor Air Quality: Dampness and Mold," which provided a comprehensive review of scientific research on health issues related to buildings and biological agents associated with dampness. The report's conclusion is that the most significant impact of mold is to make respiratory syndrome, allergies, and asthma more prevalent, as well as interfere with the immune system.
Therefore, to prevent mold growth during the storage, transportation, and pre-sale storage of dyed fabrics, it is necessary to add fungicides to the treatment process, and after anti-bacterial and anti-mold finishing, to prevent mold growth.
