Abstract

The invention discloses a refining-dyeing one-bath process efficient short-process dyeing and finishing process for a chinlon knitted fabric. The process comprises the following steps: presetting for30 seconds at the temperature of 180-190 DEG C at the speed of 40-45 m / min, refining and dyeing for 30-45 minutes at the bath ratio of 1:8 at the temperature of 100 DEG C, and after-finishing for 30-45 seconds at the setting temperature of 190-200 DEG C at the speed of 30-40 m / min; the formula of refining and dyeing comprises 2-5 g / L of refining-dyeing one-bath degreaser, 2-3 g / L of chelated dispersing agent, 1-2 g / L of chinlon levelling agent, and 0.1-10 owf of weak acid dye; and the after-finishing needs 10-20 g.L<-1> of a functional finishing agent. According to the refining-dyeing one-bathprocess efficient short-process dyeing and finishing process for the chinlon knitted fabric, the chinlon knitted fabric is preprocessed and dyed in the short process through the refining-dyeing one-bath process, the size and morphological stability of the chinlon knitted fabric is guaranteed, and the problems of fabric wrinkling, bruising, dyeing effect, dyelot chromatism and the like in the conventional process are eliminated.

Description

technical field [0001] The present invention relates to a kind of textile dyeing and finishing processing technology, more specifically, it relates to a kind of polyamide fiber knitted fabric scouring and dyeing one-bath efficient short-process dyeing and finishing process, which belongs to the field of textile dyeing and finishing processing. Background technique [0002] Nylon is the trade name of synthetic polyamide fibers, commonly known as nylon, and its basic constituents are aliphatic polyamides linked by amide bonds -NHC0-. Nylon 6 macromolecules commonly used in textile fabrics are mainly composed of three parts, namely hydrophobicity The methylene moiety, the hydrophilic amide group and the amino and carboxyl groups at the chain ends. Although the amino group content of nylon is low, its molecular chain has a large number of methylene groups that can form van der Waals force and hydrogen bonds with dyes, so nylon can not only combine with anionic dyes through ionic...
