Are there any dangers of sponge bras?

Bra is a necessity for every woman. There are many types of bras, but the most common one is the sponge bra. Sponge bras are not only soft and comfortable, but also make women more confident. However, wearing sponge bras for a long time can also be dangerous. Sponge bras contain fantasy snow elements which are very harmful to the human body and are difficult to clean. In severe cases, they can cause breast diseases and even affect the baby's breastfeeding.

1. The most toxic culprit in the sponge: TDI toluene diisocyanate (banned product during the Olympics)

TDI is a highly toxic chemical. Although there is no direct evidence that TDI is related to breast cancer, animal experiments have shown that TDI is absorbed by mice and decomposes into TDA (toluenediamine) when heated. TDA is a recognized carcinogenic chemical. Experiments have also proven that abnormal presence of TDA can be detected in the urine of workers operating in a TDI environment.

There is always a threat that trace amounts of TDI gas emitted from the PU sponge cups could be absorbed by the breasts through the skin. Although there is no way to prove it. However, my country's quality inspection units require that newly renovated homes be tested for the concentration of TDI volatile gases, which are emitted from PU wood paint, and the toxicity of TDI is also apparent.

2. Sponges cause serious damage to the earth's environment, threatening human survival.

During the production of sponges, the volatilized gases of CFC series foaming agents seriously damage the ozone layer of the atmosphere, causing the temperature of the earth to rise sharply and changing the environment that is beneficial to human life. Although no substitutes with the same cost-effectiveness have appeared so far, Chinese law has stipulated that the use of CFC series foaming agents that destroy the ozone layer will be completely banned in 2010.

3. Sponge bras, due to the characteristics of their composition and tissue structure, can also harbor dirt and filth.

Due to the instability of the molecular structure of the sponge, it is very easy to turn yellow, and almost no manufacturer uses PU sponge to make plain white bras (without lace or other coverings). Also, due to the honeycomb structure of the sponge, it is tightly organized and not easy to breathe. When you sweat, water molecules are stored in the honeycomb, creating a stuffy feeling. Not only is it difficult to dry, but it is also easy to harbor dirt and become a breeding ground for bacteria.

4. Sponge bras cannot be cleaned thoroughly.

Sponge underwear has strong adsorption capacity and is made of petroleum waste. When you wash it, the sponge is quietly absorbing detergents, soaps and other cleaning products. No matter how you wash it, it will not be thoroughly clean. Our chests breathe mainly through the nipples. Just imagine what would happen if our nipples were surrounded by clean elements and dirty things for a long time. The consequences would be serious.
