1. It is mainly used as a leveling agent for cationic dyes in the dyeing of acrylic fibers, and the dyed fabrics have a soft texture. It is also used as a softening and finishing agent for acetate fibers and as a disinfectant. It has strong affinity for acrylic fiber and good levelness for cationic dyeing. It can be used in the same bath with cationic and nonionic surfactants. The amount used as a leveling agent for cationic dyeing of acrylic fibers should be determined according to the dye concentration. The lower the dye concentration, the greater the dosage. Generally, the amount of dye is more than 0.1%, and the amount of leveling agent DC is 1.5-2%; the amount of dye is 0.1-1.5%, and the amount of DC is 1.5-1%; the amount of dye is 1-3%, and the amount of DC is 0.5-1%. Acrylic fiber is dyed with cationic dyes. If the dyeing is too dark or the color is too dark, it can be stripped and re-dyed with leveling agent DC. Stripping is generally carried out in a bath of leveling agent DC1-1.5%, no clear powder 10-20%, 30% acetic acid 2-3%, bath ratio 1:40-80, temperature 98 ℃, treatment for 1.5h, Washing; soaping to remove the residual leveling agent DC on the fibers.
2. In the field of industrial circulating water treatment, it can be used as a bactericide and algicide, a slime stripper and a cleaning agent. Compared with dodecyl dimethyl benzyl ammonium chloride under the same dosage (buy 20/L), its killing rate of iron bacteria and sulfate reducing bacteria is higher than that of dodecyl dimethyl benzyl ammonium chloride benzyl ammonium chloride, and the latter has a better killing rate of heterotrophic bacteria than the former.
