    • The floss is comprised of a texturized yarn that has been coated and impregnated with a water-soluble polymer and the water-soluble polymer coating cured and set while the yarn is stretched and is under tension. The yarn while stretched and tensioned is at a reduced width, which allows for easier insertion of the yarn floss between teeth. The yarn floss is wound onto a spool in the decreased width condition. For use, a length of floss is removed from the spool and placed between teeth. The saliva in the mouth dissolves the cured and set water-soluble polymer with the floss expanding to fill the space between the teeth. The floss is optionally coated with flavors, medicants and other substances. These can be synthetic or naturally occurring substances such as herbal substances.
    • 牙线由已经涂覆并浸渍有水溶性聚合物的组织纱线组成,并且水溶性聚合物涂层在纱线被拉伸并处于张力下时固化和固化。 纱线被拉伸和张紧时的宽度减小,这样可以更容易地将纱线插入到牙齿之间。 在减小的宽度条件下将纱线卷绕到卷轴上。 为了使用,一段长度的牙线从卷轴上取下并放在牙齿之间。 口中的唾液溶解固化和凝固的水溶性聚合物,其中牙线膨胀以填充牙齿之间的空间。 牙线任选地涂上调味剂,药剂和其他物质。 这些可以是合成的或天然存在的物质,如草药物质。
