Problems solved by technology

[0002] The current fabric dyeing and finishing process can only dye the cloth sample into the same color, or dye a specific color distribution according to the weaving position of different fibers, and this color and pattern are preset, unified, rigid and immutable; if necessary When there are more or more complex patterns, the printing process is generally used, but the printed pattern is relatively rigid and cannot meet the needs of freedom and individualization; at the same time, the pattern will be prominent, and it is difficult to form a smooth and consistent feeling with the cloth sample, and the printing process requires complex and time consuming process

no. 1 Embodiment

[0023] Fabric pretreatment: Wash the gray fabric (knitted fabric, made of polyester and spandex) in hot water at 80°C;

[0024] Feeding: Put the fabric 1 into the dyeing tank 3, and the fabric is layered in waves in the tank; see figure 1 , a schematic diagram of laying cloth horizontally in the dyeing tank.

[0025] Dye liquor configuration: melt the dye and auxiliaries in hot water at 50°C, filter and defoam; obtain the dye liquor; defoaming the dye liquor can avoid adverse effects on some indirect dyed parts.

[0026] Dyeing: put the prepared dye solution 2 into the dye tank, the height of the dye solution is lower than the height of the cloth, and the cloth part is immersed in the dye solution; after the dye solution is put in place, the temperature of the dye solution is raised, and the heating rate of the dye solution is 2 ℃ / min, the dyeing solution is heated to 130 ℃ and then kept warm for 40 minutes to dye the fabric, the dyeing bath ratio is 1:10;

[0027] Post-trea...

Embodiment 1

[0028] The fabric dyed in Example 1: the part of the fabric located above the dye liquor absorbs the dye liquor below due to capillary action, presenting a gradual pattern effect and irregular blank (undyed) parts.

[0029] The cloth produced in Example 1 is tested for performance, and the results are shown in the table below.

[0030]

no. 2 Embodiment

[0031] The 2nd embodiment: (with high temperature overflow dyeing machine, carry out extra dark color dyeing)

[0032] Fabric pretreatment: the gray cloth (cation modified polyester) is pre-formed in the setting machine at 190°C, and the setting speed of the setting machine is 25 yards / min;

[0033] Feeding: put the shaped fabric into the dyeing tank of the high-temperature overflow dyeing machine (HISAKA WORKS CUT-XF-2L), and the fabric is layered in waves in the tank;

[0034] Dye solution configuration: Melt the dye in hot water at 50°C, filter it, and put it in the dyeing tank

[0035] Dyeing: Put the prepared dye solution into the dye tank, the height of the dye solution is lower than the height of the cloth, and the cloth part is immersed in the dye solution; after the dye solution is put in place, the temperature of the dye solution is raised, and the heating rate of the dye solution is 1°C / min, the dyeing solution is heated to 120°C and then kept warm for 40 minutes ...

Abstract

A cloth dyeing method, comprising the following steps: Feeding: placing the cloth in a dyeing tank, the cloths are stacked along the horizontal direction of the dyeing tank, dyeing: putting the dyeing liquid into the dyeing tank, and dyeing the cloth in the tank , the cloth is partly immersed in the dye liquor, and the part of the cloth above the dye liquor absorbs the dye liquor through capillary action, presenting a gradual, different-shade dyeing effect or a certain whitening effect, with a hazy aesthetic feeling. The final colors and patterns of the indirect dyed or undyed part of the fabric are different, unique and unrepeatable, meeting the needs of freedom and individualization. At the same time, the dyeing method has good dyeing stability and can be applied to the dyeing of various fabrics.

Description

technical field [0001] The invention relates to the field of printing and dyeing, in particular to a dyed cloth and a dyeing method thereof. Background technique [0002] The current fabric dyeing and finishing process can only dye the cloth sample into the same color, or dye a specific color distribution according to the weaving position of different fibers, and this color and pattern are preset, unified, rigid and immutable; if necessary When there are more or more complex patterns, the printing process is generally used, but the printed pattern is relatively rigid and cannot meet the needs of freedom and individualization; at the same time, the pattern will be prominent, and it is difficult to form a smooth and consistent feeling with the cloth sample, and the printing process requires complex and Time-consuming process. Contents of the invention [0003] For this reason, need to provide a kind of cloth that can meet the color of free, individualized demand, pattern an...
