Problems solved by technology

[0004] However, disperse dye molecules do not contain hydrophilic soluble groups such as carboxyl groups and sulfonic acid groups, so their water solubility is poor; disperse dyes are mixed with water to form a suspension of dye solution, and

Abstract

The invention relates to the technical field of textile processing, and discloses a dyeing technology of a polyester knitted fabric. The dyeing technology comprises the following steps: performing S1presetting, S2 desizing, S3 neutralization with washing, S4 dyeing, S5 continuous cleaning, S7 dehydration, S8 scutching and S9 setting on a grey fabric, wherein a used dye in S4 dyeing is prepared from the following substances in percentage by mass: 5-10 percent of monoazo dye, 3-7 percent of sodium lignosulfonate, 3-7 percent of OP-10, 15-25 percent of levelling agent, 1-3 percent of acetic acidand 48-73 percent of water. In the dyeing technology, by adding the sodium lignosulfonate and the OP-10 as dyeing auxiliaries in the dye, the monoazo dye has good water solubility; and meanwhile, theOP-10 enables the monoazo dye to be wet and prevents molecules in the monoazo dye from coagulation and then sedimentation, so that the polyester fabric is higher in colour fastness after being dyed,and the colour and lustre of the dyed polyester fabric are more lasting under the natural environment of exposing to sun and wind.

Description

technical field [0001] The invention relates to the technical field of textile processing, more specifically, it relates to a dyeing process of polyester knitted fabric. Background technique [0002] Polyester is a synthetic fiber that is widely used in textiles and has excellent comprehensive properties. The polyester filament fabric must be sized before weaving, so that the surface of the filament is covered with a smooth, flexible and firm size film, so as to enhance the cohesion and wear resistance of the polyester filament, so that it can withstand various stresses during the weaving process. Friction and tension make the weaving production run smoothly under the requirements of high quality and high yield. Polyester knitted fabrics are softer than polyester woven fabrics and are often used to make sun protection clothing. Therefore, polyester knitted fabrics have high requirements for color fastness after dyeing and finishing. [0003] Polyester fibers are hydrophobi...
