[0018] Example 1
[0019] A biological enzyme finishing process for hemp yarn and hemp fabrics, using an overflow dyeing machine with a bath ratio of 1:6 to perform biological enzyme finishing treatment:
[0020] (1) Low-temperature neutral composite enzyme singeing: Place the composite enzyme ingredients in the tank, turn on the stirring device to mix the composite enzyme ingredients evenly, control the pH of the composite enzyme ingredients to 6.5, and then raise the temperature to 50°C to obtain a solution. Use the expansion machine with the lower machine width of 160cm, control the overfeeding amount to 1% and the cloth speed to 90m / min, put the hemp yarn and hemp cloth to be processed into the solution, keep the cloth below the liquid level, and keep it warm for 30 minutes;
[0021] (2) Low temperature neutral complex enzyme softness: Put the soft ingredients in the material tank, turn on the stirring device to mix the soft ingredients evenly, control the pH of the soft ingredie...

[0025] Example 2
[0026] A biological enzyme finishing process for hemp yarn and hemp fabrics, using a continuous long car production line for biological enzyme finishing treatment:
[0027] (1) Low-temperature neutral composite enzyme singeing: Add the composite enzyme ingredients into the automatic feeding device, then add the composite enzyme ingredients into two tanks, control the pH value of the composite enzyme ingredients to 8.0, and then raise the temperature to 60°C to obtain For solution, use an expander with a lower machine width of 170cm to control the overfeed amount to 3% and the cloth speed to 110m / min. Put the hemp yarn and hemp fabric to be processed into the solution, keep the fabric below the liquid level, and keep warm 60min;
[0028] (2) Low-temperature neutral complex enzyme softening: Add soft ingredients into the automatic feeding device, then add the soft ingredients into two tanks, control the pH of the soft ingredients to 8.0, and then heat up to 60°C to ...
