Embodiment 1
[0030] Stack 14 kilograms of flax two crude fibers in a sealed room at 18°C for 40 hours of wet health, so that the moisture regain of the hemp fiber is controlled at 15%; the fiber carding machine is used to comb and remove impurities to make 10 kilograms; after removing impurities The two crude fibers of flax are packed into the bulk fiber dyeing vat in an orderly manner, add 125 kg of water in the bulk fiber dyeing vat to adjust the water temperature to 55°C, the pH value to 7-8, and add 0.1 kg of biological compound scouring enzyme (product of Bayer Chemical Co., Ltd., Germany) , treatment time is 2 hours; then wash twice with 80°C hot water for 18 minutes; then pour 130 kg of water into the loose fiber dyeing vat, add 0.75 kg of NaoH, 0.1 kg of JFC penetrant, Na 2 SiO 3 0.2 kg, 0.4 kg of 209 lotion, adjust the water temperature to 95°C, and extract for 60 minutes; then wash twice with 80°C hot water for 15 minutes; wash at room temperature for 15 minutes to remove impur...
Embodiment 2
[0032] Divide 72 kg of flax fiber into 4 layers and spray water, that is, the first layer of fiber, spray water, the second layer of fiber, spray water --- to ensure uniform moisture distribution, and stack them in a sealed room at 25°C for 36 hours of moisture preservation , so that the moisture regain of the hemp fiber is controlled at 16%, and the fiber carding machine is used to card and remove impurities to make (by 70% production rate) 50 kilograms; Fiber dyeing vat, add 750 kg of water to the bulk fiber dyeing vat, adjust the water temperature to 50°C, pH value 7-8, add 0.75 kg of biological compound scouring enzyme (product of Genencor, USA), and process for 2.5 hours; then use 80°C Wash twice in hot water for 15 minutes; then add 750 kg of water to the loose fiber dyeing vat, add 3.75 kg of NaoH, 0.5 kg of JFC penetrant, and 2 SiO 3 1 kg, 3 kg of sodium dodecylbenzene sulfonate, adjust the water temperature to 95°C, and extract for 60 minutes; then wash twice with h...
Embodiment 3
[0034] Divide 143 kg flax fiber into 6 layers and spray water, stack it in a sealed room at 20°C for 48 hours, so that the moisture regain of the flax fiber can be controlled at 18%. kg; the flax two crude fibers after impurity removal are packed into bulk fiber dyeing vat orderly, add 1000 kg of water in the bulk fiber dyeing vat to adjust water temperature 53 ℃, pH value 7-8, add biological compound scouring enzyme (German Bayer Chemical company product) 1 kg, treatment time 3 hours; then wash twice with 80 ℃ hot water for 20 minutes; then add 1000 kg of water to the loose fiber dyeing vat, add 7.5 kg of NaoH, 1 kg of JFC penetrant, Na 2 SiO 3 2 kg, 2 kg of 209 lotion, adjust the water temperature to 95°C, and extract for 60 minutes; wash twice with hot water at 80°C for 20 minutes; wash at room temperature for 20 minutes to remove impurities, put it into a dehydrator for dehydration, and take it out, Use spray method, add 3% (o.w.f) hydrogenated amino natural fatty alcoho...
