Embodiment 1

[0020] A kind of dyeing process of modal fabric, comprises the following steps:

[0021] (1) Put the modal fabric to be dyed in the washing bucket, where the volume of the washing bucket is 11 times the volume of the modal fabric, add a penetrating agent with a mass fraction of 1%, and rotate the washing bucket at a low speed for 10 minutes and then at a high speed for 5 minutes;

[0022] (2) Place the wet modal fabric on the work platform, fix the edge area of ​​the modal fabric, and let the fabric stretch out naturally; perform pre-setting heat treatment on the surface of the modal fabric, so that there are no wrinkles on the fabric and it is naturally flat;

[0023] (3) Put the fabric in the washing bucket, and pour 12 times its volume of mixed dye into the washing bucket at the same time, and then rotate the washing bucket at a low speed for 15 minutes again, wherein the mixed dye includes the following components by mass: 50 parts of reactive dyes 6 parts of carboxylic ac...

Embodiment 2

[0028] A kind of dyeing process of modal fabric, comprises the following steps:

[0029] (1) Put the modal fabric to be dyed in a washing bucket, where the volume of the washing bucket is 15 times the volume of the modal fabric, add a penetrating agent with a mass fraction of 2%, and rotate the washing bucket at a low speed for 10 minutes and then at a high speed for 5 minutes;

[0030] (2) Place the wet modal fabric on the work platform, fix the edge area of ​​the modal fabric, and let the fabric stretch out naturally; perform pre-setting heat treatment on the surface of the modal fabric, so that there are no wrinkles on the fabric and it is naturally flat;

[0031] (3) Put the fabric in the washing bucket, and pour the mixed dye 15 times its volume into the washing bucket at the same time, and then make the washing bucket rotate at a low speed again for 30 minutes, wherein the mixed dye includes the following components in terms of mass: 80 parts of reactive dyes 15 parts of...

Embodiment 3

[0036] A kind of dyeing process of modal fabric, comprises the following steps:

[0037] (1) Put the modal fabric to be dyed in a washing bucket, where the volume of the washing bucket is 13 times the volume of the modal fabric, add a penetrating agent with a mass fraction of 1%, and rotate the washing bucket at a low speed for 10 minutes and then at a high speed for 5 minutes;

[0038] (2) Place the wet modal fabric on the work platform, fix the edge area of ​​the modal fabric, and let the fabric stretch out naturally; perform pre-setting heat treatment on the surface of the modal fabric, so that there are no wrinkles on the fabric and it is naturally flat;

[0039] (3) Put the fabric in the washing bucket, and pour the mixed dye 14 times its volume into the washing bucket at the same time, and then make the washing bucket rotate at a low speed again for 22 minutes, wherein the mixed dye includes the following components by mass: 65 parts of reactive dyes ; 10 parts of carbox...

Abstract

The invention discloses a process for dyeing modal fabrics, which adopts a set of systematic and complete dyeing technology process from water washing, presetting to dyeing, and is matched with a mixed dye combination which is specially made according to the modal fabrics, and fastens color for modal fibers in dyes through ultrasound by utilizing an high-low ultrasonic switching process. The process for dyeing the modal fabrics is simple in operation, enables dyeing color of fabrics to be fresh and not to lose color by utilizing the high-low ultrasonic switching process, improves degree of friction of dry and wet colors under the premise that extra external force is not acted on the model fabrics, and is excellent in dyeing effect, uniform not to lose color and high in industrialization degree.

Description

technical field [0001] The invention relates to a fabric processing method, in particular to a dyeing process for modal fabrics. Background technique [0002] Modal fiber is a kind of cellulose fiber, so its dyeing performance is similar to that of viscose fiber and cotton fiber, and it can be dyed with reactive dyes and direct dyes. However, due to the particularity of modal fiber, it is more sensitive to dye auxiliaries, which brings certain difficulties to the dyeing process of the fiber. If there is no suitable process and suitable dye, it is difficult to achieve the high uniformity of modal fabric dyeing. Quality staining effect. [0003] Therefore, a new technology is needed to solve the above problems. Contents of the invention [0004] Purpose of the invention: In order to solve the problems existing in the prior art, the present invention provides a dyeing process for modal fabrics that is more systematic, simple to operate, uniform in dyeing effect, and not eas...
