Example Embodiment
[0019] Example 1:
[0020] (a) Preparation process: prepare the hemp / cotton blended yarn to be dyed;
[0021] (b) Cone loosening process: use YH18SD cone loosening machine to roll the yarn around the city cone or cylindrical;
[0022] (c) Scouring and bleaching process: Use scouring and oxygen bleaching to remove impurities on the yarn and complete the bleaching treatment of the yarn. The scouring and bleaching process is as follows: sodium hydroxide 1g / L, carbonic acid Sodium 1g / L, sodium silicate 3.1g / L, hydrogen peroxide 3.0g / L, sulfuric acid 1g / L, bath ratio 1:13, temperature 80°C, scouring time 55min;
[0023] (d) Dyeing process: the yarn is dyed. The dyeing is to use D-type reactive dye to dye the yarn. The dyeing formula is as follows: D-type reactive dye concentration is 75g / L, bath ratio is 6:1, The temperature is 70℃, and the dyeing time is 60min;
[0024] (e) Fixing process: use high concentration chlorine resistant fixing agent HH-008S to fix the dyed yarn, its concentrati...

[0043] Example 3:
[0044] (a) Preparation process: prepare the hemp / cotton blended yarn to be dyed;
[0045] (b) Cone loosening process: use YH18SD cone loosening machine to roll the yarn around the city cone or cylindrical;
[0046] (c) Scouring and bleaching process: Use scouring oxygen bleaching method to remove impurities on the yarn and complete the bleaching treatment of the yarn. The scouring and bleaching process is as follows: sodium hydroxide 2g / L, carbonic acid Sodium 0.9g / L, sodium silicate 4g / L, hydrogen peroxide 3.2g / L, sulfuric acid 1g / L, bath ratio 1:20, temperature 90℃, scouring time 70min;
[0047] (d) Dyeing process: the yarn is dyed. The dyeing is to use D-type reactive dyes to dye the yarn. The dyeing formula is as follows: D-type reactive dye concentration is 100g / L, bath ratio is 15:1, Dyeing temperature is 50℃, dyeing time is 50min;
[0048] (e) Fixing process: use high concentration chlorine resistant fixing agent HH-008S to fix the dyed yarn, its concentrati...
