Embodiment 1
[0022] A waterproof cotton cloth with good antibacterial properties, comprising the following raw materials in parts by weight: 16 parts of absorbent cotton cloth, 4.6 parts of tourmaline stone powder, 2.4 parts of cellulose, 3 parts of negative ion powder, 6 parts of mugwort leaves, 4 parts of polyvinyl alcohol, tartaric acid 3 parts, 2.6 parts of sodium laureth sulfate and 4 parts of chitosan. As the cellulose, hydroxymethyl cellulose was used.
[0023] The preparation method of the good waterproof cotton cloth of described antibacterial property, concrete steps are as follows:
[0024] Step 1, wash the leaves of mugwort and enzymolyze them at a pH of 5.9 and 38 degrees Celsius. After the enzymolysis is complete, the enzyme is inactivated to obtain the enzymatic hydrolyzate of mugwort leaves;
[0025] Step 2, mixing tourmaline powder and negative ion powder and maintaining it in an electric field of 570V for 5 minutes to obtain the first mixture;
[0026] Step 3, uniformly...
Embodiment 2
[0031] A waterproof cotton cloth with good antibacterial properties, comprising the following raw materials in parts by weight: 18.6 parts of absorbent cotton cloth, 5.9 parts of tourmaline stone powder, 2.8 parts of cellulose, 3.5 parts of negative ion powder, 7.2 parts of Artemisia argyi, 4.7 parts of polyvinyl alcohol, tartaric acid 3.8 parts, 3.3 parts of sodium laureth sulfate and 5 parts of chitosan. The particle diameter of tourmaline powder is 0.32mm, and the particle diameter of negative ion powder is 120nm.
[0032] The preparation method of the good waterproof cotton cloth of described antibacterial property, concrete steps are as follows:
[0033] Step 1, wash the leaves of mugwort and enzymolyze them at a pH of 6.5 and 38 degrees Celsius. After the enzymolysis is complete, the enzyme is inactivated to obtain the enzymatic hydrolyzate of mugwort leaves;
[0034] Step 2, mixing tourmaline powder and negative ion powder and maintaining in the electric field for 6 mi...
Embodiment 3
[0040] A waterproof cotton cloth with good antibacterial performance, comprising the following raw materials in parts by weight: 22.6 parts of absorbent cotton cloth, 6.9 parts of tourmaline stone powder, 3.6 parts of cellulose, 4 parts of negative ion powder, 8.4 parts of mugwort leaves, 5.5 parts of polyvinyl alcohol, tartaric acid 4.2 parts, 3.9 parts of sodium laureth sulfate and 6.1 parts of chitosan. Cellulose includes mixtures of hydroxymethylcellulose and hydroxypropylmethylcellulose. The particle diameter of tourmaline powder is 0.24mm, and the particle diameter of negative ion powder is 80nm.
[0041] The preparation method of the good waterproof cotton cloth of described antibacterial property, concrete steps are as follows:
[0042] Step 1, clean the leaves of mugwort and enzymolyze them at a pH value of 6.6 and 40 degrees Celsius with the assistance of 95W ultrasonic waves. After the enzymolysis is complete, the enzyme is inactivated to obtain the enzymatic hydro...
