The invention discloses a low-temperature
dyeing and finishing technology of cottonette. The technology comprises the following steps: pretreatment; preshaping; modification treatment;
dyeing;
mordant removing; soaping; color fixing; post-treatment;
drying; shaping; calendaring; rolling. According to the technology, pretreatment is carried out through the adoption of
helicase and alpha-
amylase, and modification treatment is carried out before
dyeing, so that the property of the cottonette is fundamentally modified, and the dye-uptake of the fabric is increased; during the dyeing procedure, large quantities of alkaline substances and inorganic salt are not used, and a
levelling agent, a low-temperature dyeing
accelerant, a migration inhibitor and a dispersing agent are added, so that the dye uniformity is improved; during the whole dyeing process, the temperature is lower than 80 DEG C, and the dyeing process belongs to low-temperature dyeing, so that
energy consumption is reduced; self-cleaning treatment is added in post-treatment, so that the self-cleaning capacity,
wrinkle resistance and water washable firmness of the fabric are improved; post-treatment is carried out through the adoption of silk
fibroin and
sericin, so that the pilling resistance and antistatic property of the cottonette are improved; the whole technology is environment-friendly and free of
pollution.
