[0026] C60 / T40 63”32*32 130*70 2 / 1 mesh fabric national flag red dyeing process, with cellulose fiber and polyester fiber blended fabric as the dyeing object, including desizing → scouring → oxygen bleaching → singeing → Mercerizing-booking-→coloring→finishing→setting eight steps.

[0027] The coloring step is to dye the polyester fibers with disperse dyes first, and then dye the cellulose fibers with reactive dyes, so that the two colors are consistent.

[0028] The step of dyeing polyester fibers with disperse dyes is to use disperse dyes to dye the polyester fibers of the blended fabric of cellulose fibers and polyester fibers, which specifically includes the step of disperse dyeing, which specifically includes pad dyeing and coloring , pre-baking, baking, steaming, soaping, drying steps. The soaping temperature is controlled at 90°C, soaping in 4 tanks, and the soaping time is 2-3 minutes. The soaping agent is evenly added to the soaping tanks with flow control, and the a...

Abstract

The invention relates to a national flag red dyeing process for cellulose fiber and polyester fiber blended fabrics. The national flag red dyeing process includes the eight steps of desizing, boiling,oxygen bleaching, singeing, mercerizing, coloring, after-finishing and shaping. The coloring step includes dispersion dyeing and reactive dyeing which are carried out in sequence, wherein disperse dye used for the dispersion dyeing specifically includes 8-34g / L of Serilene bright red SWF-N and 0.9-3.6g / L of Serilene dark red SWF-N, and reactive dye for the reactive dyeing specifically includes 4.6-18.4g / L of Intracron red CD, 3.5-14g / L of Intracron golden yellow MD and 1.7-7.0g / L of Intracron vital red M-2B. The national flag red dyeing process has the advantages that the problem of poor color fastness to red soaping, water soaking and light of the cellulose fiber and polyester fiber blended fabrics is solved through screening of suitable dye, coordination among different dye formulas andreasonable techniques, and the fabrics dyed by the process have excellent color fastness properties.

Description

technical field [0001] The invention relates to a dyeing process formula, in particular to a national flag red dyeing process, in particular to a national flag red dyeing process for cellulose fiber and polyester fiber blended fabrics. Background technique [0002] The existing dyeing technology has the problem of poor color fastness to wet rubbing and soaping for the red color of cotton fabrics, polyester-cotton fabrics, and cotton-polyester fabrics. In the application of tooling, there are often all-red tooling, which is often used in daily life. According to the design requirements, color matching or matching with light-colored clothes is mainly reflected in the friction between white shirts and color matching, and the white shirt partially turns red or the national flag red and light-colored clothes are washed. The fastness is not good, it will wash off with soap and then stain other block colors or other medium and light colors that seem to wash together. In addition, ...
