[0008] Preferably, the ratio of the mildew-proof antibacterial agent to water is 1:50 to 1:100.

[0009] Preferably, the ratio of the hemp yarn, silk thread, cotton fiber, elastic fiber, and polypropylene is 35:20:25:15:5.

[0010] Another technical problem to be solved by the present application is to provide a hemp cotton blended yarn and a preparation method thereof, comprising the following steps:

[0011] 1) First, prepare the container, linen, silk, elastic fiber and propylene fiber are classified and cleaned, and fully washed for 10-15 minutes. During this time, the antistatic agent is prepared according to a ratio of 1:100. The prepared antistatic agent is added to the inside of the cleaning container, and the raw materials are fully soaked to reduce static electricity on the yarn. Then, the cleaned linen, silk, elastic raw materials are dried, and the antistatic effect on the raw materials is consolidated again by spraying after drying.

[0012] 2) The treated linen, silk, elastic fiber and propylene fiber and cotton fiber are mixed according to the proportion, and are twisted into a yarn. The white yarn is prepared by primary twisting and re-twisting.

[0013] 3) Dyeing, the synthetic yarn is dyed and lubricated. The synthetic yarn is immersed in the prepared dye vat for a suitable time. After dyeing, the yarn is immersed in the fixing agent for a suitable time until the dyeing is completed.

[0014] 4) Mold-proof treatment, first prepare 30-45 degree warm water, and mix the mold-proof and antibacterial agent according to a ratio of 1:50. After mixing, the mixture is stirred uniformly with a stirring rod. After uniform stirring, the dyed yarn is immersed in the prepared solution for 3-8 hours. Stir every hour and turn over to keep the yarn evenly immersed, so as to obtain a yarn with better mold-proof and antibacterial effect.

[0015] 5) After soaking, the yarn is dried uniformly. The mold-proof and antibacterial agent prepared in the previous step is filled in a watering can, and the dried yarn is sprayed again to obtain a better mold-proof yarn.

[0016] 6) After completion, the yarn is wound and stored.
