Problems solved by technology

For pure nylon fabrics, disperse dyes are mainly used for printing, and reactive dyes, vat dyes, neutral dyes or weak acid dyes can also be used for printing. The existing problems are: the light fastness of disperse dyes on nylon is not good enough; The printing hue is not stable enough, and the color fastness is not ideal. Vat dyes can only be used in medium and light colors. Neutral dyes or weak acid dyes need to be developed in a steamer. During the process, there may be relative movement between the fabric and the guide roller. Cause cross-color
This condition is exactly the working condition of a vertical or horizontal steamer for knitted fabrics. The fabric is in a hanging state in this type of equipment, and the width will change after steaming, which has the disadvantage of inconsistent width.
Therefore, these common traditional steaming methods are generally difficult to achieve satisfactory results

Abstract

The invention discloses a chinlon or chinlon / cotton blended printed fabric and a preparation method thereof. The preparation method comprises the steps of (1) boiling and bleaching a gray fabric which is a chinlon fabric or chinlon / cotton blended printed fabric; (2) printing the gray fabric subjected to boiling and bleaching, wherein when the gray fabric is the chinlon fabric, a printing paste for printing is a neutral dye, and when the gray fabric is the chinlon / cotton blended printed fabric, the printing paste for printing is a mixture of the neutral dye and a reduced dye; (3) steaming and soaping the fabric obtained after printing treatment, and then drying to obtain a product. The printed fabric provided by the invention is full, rich and bright in color and high in color fastness, and has a clean cloth cover, clear pattern outlines and stable product quality.

Description

technical field [0001] The invention relates to a nylon or nylon / cotton blended printed fabric and a preparation method thereof. Background technique [0002] Compared with polyester or polyester-cotton blended fabrics commonly used in China, nylon or nylon-cotton blended fabrics have better wear resistance, and the dyeing materials and dyeing and finishing processes corresponding to the dyed fabrics are very mature, and the hue and color fastness can reach polyester Or the level of polyester-cotton blended fabrics; but for printing, limited to traditional technology and equipment, most methods are to directly adopt the process of polyester or polyester-cotton blended fabrics. For pure nylon fabrics, disperse dyes are mainly used for printing, and reactive dyes, vat dyes, neutral dyes or weak acid dyes can also be used for printing. The existing problems are: the light fastness of disperse dyes on nylon is not good enough; The printing hue is not stable enough, and the colo...
