Do your clothes smell like Torreya grandis? New antibacterial yarn

Core summary: Torreya grandis is a treasure from head to torreya grandis, even the outer aril of Torreya grandis fruit is no exception. Recently, Shanghai Donghua University cooperated to apply Torreya grandis essential oil extracted from Torreya grandis green peel to the textile field, and successfully developed the first "torreya grandis" antibacterial yarn in China.

This antibacterial yarn infused with Torreya grandis essential oil, from the appearance, these yarns are no different from ordinary yarns, but if you smell it closely, you can smell the faint Torreya grandis fragrance emitted by the yarn.

"After analysis, it was found that there are more than 40 substances in Torreya grandis essential oil, which form the unique smell of Torreya grandis essential oil, and this smell has a sedative effect. With the deepening of research, it was found that this essential oil also has antibacterial and antibacterial effects." Donghua University materials science doctor introduced. Utilize the antibacterial and antibacterial effects of Torreya grandis essential oil, combine it with textiles, and develop functional fabrics.

At the beginning, the researchers first used the direct injection method to produce fabrics, but after several washes, there was little essential oil left in the fabric. After hitting a wall, the R&D team tried to explore more paths to achieve the research goal. After nearly a year of scientific research, the Donghua University research team finally successfully developed the Torreya grandis essential oil micron encapsulation technology.

"The so-called micron encapsulation technology is to solidify Torreya grandis essential oil into microcapsules through a special process, and then add it to the spinning system to make Torreya grandis fiber. In this way, the yarn and textiles produced have slow release of essential oils and longer-lasting antibacterial and bacteriostatic effects." The test process has to go through harsh chemical environments such as acid and alkali and complex processes such as high-temperature washing, and it is necessary to ensure that the essential oil is still in the fiber. Now it has finally succeeded.

"What's more amazing is that unlike general antibacterial agents that need to be in contact to have an antibacterial effect, Torreya grandis yarn itself has a volatile effect. With the release of essential oils, a non-contact antibacterial and bactericidal effect can be formed near the textiles.".

After experimental demonstration, the antibacterial and antimicrobial effect of this Torreya grandis fiber yarn was recognized by experts and obtained a national patent, becoming the world's first zero-heavy metal, non-contact antibacterial yarn.
