The invention discloses a
wrinkle-resistant
dyeing and finishing process of a
ramie fabric. The process includes the following steps that S1, pretreatment is performed; S2,
wrinkle-resistant finishingis performed, wherein the
ramie fabric obtained through the pretreatment in the step 1 is immersed in finishing liquid at 45-55 DEG C, the bath ratio is 1:25:35, immersion and rolling are performed twice respectively, the rolling rate is 80-95%, pre-
drying is performed at 70-90 DEG C,
steaming is performed under
humidity at 110-120 DEG C, and
drying is performed after
water washing at 60-70 DEGC; S3, reactive
dyeing is performed, wherein the
ramie fabric obtained through
wrinkle-resistant finishing in the step 2 is immersed into
dyeing liquid formed by
reactive dye, the bath ratio is 1:(20-30), the temperature is increased to 40-50 DEG C, heat preservation is performed, dyeing is performed, the temperature is increased to 60-80 DEG C, an alkaline agent is added, heat preservation is performed, the temperature rises to 90-100 DEG C, heat preservation and dyeing are performed, and after the temperature is reduced to
room temperature,
water washing, soaping and
drying are performed insequence. The invention further discloses the ramie fabric.
Quaternary ammonium salt of
chitosan, oxidized
microcrystalline cellulose,
metal oxide sol and
sodium tartrate cooperate and serve as a wrinkle-resistant finishing solution of the ramie fabric, through cooperation with wet
steaming, cross-linking of ramie fibers is effectively promoted, and the wrinkle-resistant performance is improved.
