Embodiment 1
[0024] The concentration of friction and weighting agent in water is 52g / L, and the pH value is 7.0, in which polymethyl acrylate, emulsifier sodium dodecylbenzene sulfonate, softener fatty alcohol polyoxyethylene ether, inorganic metal salt chlorination The mass ratio of calcium, anionic surfactant sodium dodecylbenzenesulfonate and nonionic surfactant fatty alcohol polyoxyethylene ether is 0.3:2:2:60:3:1.
[0025] The temperature is 20°C, and the spraying process is adopted, and the constant temperature and humidity room (temperature (25±2)°C, relative humidity (65±2)%) is balanced for 48h. The weight gain rate of treated fibers can reach about 10%, the cohesion between fibers has been greatly improved, smooth spinning can be carried out, the blending ratio can be as high as 80%, and the count of yarns can be from 20 to - 50 sticks.
Embodiment 2
[0027] The concentration of the friction and weighting agent in water is 43g / L, and the pH value is 7.5, wherein polyacrylic acid, emulsifier sodium dodecylbenzene sulfonate, softener fatty alcohol polyoxyethylene ether, inorganic metal salt calcium chloride, The mass ratio of the anionic surfactant sodium dodecylbenzenesulfonate and the nonionic surfactant fatty alcohol polyoxyethylene ether is 0.2:1:1.5:55:2:1.
[0028] The temperature is 25°C, and the crystal cotton fiber is treated with the friction and weighting agent, and the constant temperature and humidity room (temperature (25±2)°C, relative humidity (65±2)%) is balanced for 48h. The weight gain rate of treated fibers can reach about 10%, the cohesion between fibers has been greatly improved, smooth spinning can be carried out, the blending ratio can be as high as 80%, and the count of yarns can be from 20 to - 40 sticks.
Embodiment 3
[0030] The concentration of friction and weighting agent in water is 82g / L, and the pH value is 6.5, including sodium alginate, emulsifier sodium dodecylbenzene sulfonate, softener fatty alcohol polyoxyethylene ether, inorganic metal salt calcium chloride The mass ratio of the anionic surfactant sodium dodecylbenzenesulfonate and the nonionic surfactant fatty alcohol polyoxyethylene ether is 1:3:3:90:3:1.
[0031] The temperature is 25°C, and the crystal cotton fiber is treated with the friction and weighting agent, and the spraying method is adopted, and the constant temperature and humidity room (temperature (25±2)°C, relative humidity (65±2)%) is balanced for 12h. The weight gain rate of treated fibers can reach about 12%, the cohesion between fibers has been greatly improved, smooth spinning can be carried out, the blending ratio can be as high as 80%, and the count of yarns can be from 30 to - 60 sticks.
