Embodiment 1

[0021] A kind of pigment printing method of weft knitted fabric, comprises the following steps:

[0022] (1) Modification pre-treatment: put the weft-knitted fabric in the refrigerator for 1 hour at low temperature and then take it out, use the glow sub-atmospheric low-temperature plasma surface treatment equipment as the operating platform, and use O 2 / Ar mixed atmosphere is used as the modification treatment atmosphere for low-temperature plasma modification pre-treatment;

[0023] (2) Washing pre-treatment: put the modified pre-treated fabric into a washing machine in bags for washing, add 1g / L acid detergent and 1g / L enzyme treatment agent, the temperature is 50°C, and the bath ratio is 1: 20. The washing time is 25 minutes; after washing, dehydrate to 70% dry;

[0024] (3) Bleaching treatment: the weft knitted fabric after washing is carried out bleaching treatment, bath ratio 1:10, adding the mixed bleaching agent of the sodium citrate of 1g / L, the sodium salicylate of...

Abstract

The invention discloses a pigment printing method for a weft-knitted fabric. A technological processes including treatment before modification, treatment before washing, bleaching treatment, printing,ageing and fixation and aftertreatment, treatment before modification is carried out before printing to carry out modification treatment on the weft-knitted fabric, then treatment before washing andbleaching treatment are carried out, on the one hand, the shortcoming that a weft-knitted fabric is difficult to dye is overcome, on the other hand, the circumstance of unevenness of printing caused by shrinkage or texture characteristics in a pigment printing process is avoided effectively, moreover, printing is carried out by specially-made pigment ink for pigment printing, and the washability and absorption of the weft-knitted fabric are enhanced. The pigment printing method for the weft-knitted fabric has the advantages of smooth printing, bright color, suitable coloring depth, no easinessin fading, simplicity in process and the like.

Description

technical field [0001] The invention relates to a fabric processing method, in particular to a paint printing method for weft knitted fabrics. Background technique [0002] Pigment printing is a printing method that uses a polymer compound as an adhesive to mechanically adhere the pigment to the fabric, and obtains a transparent resin pattern with certain elasticity, wear resistance, hand rubbing resistance and wrinkle resistance after post-processing. The mechanism on the fiber is different from that of other dyes fixed on the fiber. It relies on the adhesive to form a fast, colorless and transparent film on the fabric, and mechanically covers the paint on the fabric. Therefore, pigment printing is suitable for Most fibers, and the process is simple, the printing effect is better. [0003] Weft-knitted fabric is a knitted fabric in which one or more yarns are formed into loops in the transverse direction on a weft-knitting machine, and the loops are nested in series. The ...
