It broke, get a new string. Seriously, I know of no meaning for this, and in fact, the red string thing seems not to be a deeply embedded or central tradition of Kabbalah.

People wear a red string on their wrists for the religion Kabbalah.

Yes.

(You should be aware that these strings are trinkets; knickknacks; and they have zero spiritual significance.)

Different religions have their own customs and symbolism, and the wearing of red bracelets in Hinduism and Kabbalah represents different things. In Hinduism, a red bracelet, known as a "kumkum" or "mangalsutra," is worn by married women to signify marital status and to bring good fortune. In Kabbalah, a red string bracelet, known as a "red string of fate," is worn to ward off evil spirits and bring protection and blessings.
