Embodiment Construction

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0019] This embodiment provides a yarn dyeing process provided by the present invention, and the dyeing process is:

[0020] Step 1: Place the yarn on the loose tube to loosen the yarn;

[0021] Step 2: Add the yarn to lye for bleaching, and add stabilizer at the same time;

[0022] Step 3: Add acid to neutralize the bleached yarn and then wash it with water;

[0023] Step 4: Steam the washed yarn at high temperature;

[0024] Step 5: Dyeing the high-temperature steamed yarn once;

[0025] Step 6: Steam the dyed yarn once;

[0026] Step 7: Perform secondary dyeing on the steamed yarn;

[0027] Step 8: Add the secondary dyed yarn to the fixing agent for fixing;

[0028] Step 9: The yarn ...

Abstract

The invention provides a yarn dyeing process which includes the steps: firstly, placing yarns on a loosening cylinder to loosen the yarns; secondly, adding the yarns into alkaline liquor to whiten theyarns, and adding stabilizers; thirdly, adding acid to neutralize the whitened yarns, and washing the neutralized yarns; fourthly, stewing the washed yarns at high temperature; fifthly, primarily dyeing the yarns stewed at high temperature; sixthly, steaming the primarily dyed yarns; seventhly, secondarily dyeing the steamed yarns; eighthly, adding the secondarily dyed yarns into a color fixing agent to fix colors of the yarns; ninthly, dewatering and drying the yarns, and baking the yarns. According to the method, primary dye fixation of the yarns is implemented in a steaming manner after primarily dyeing of the yarns is implemented, secondary dye fixation of the yarns is implemented in a baking manner after secondary dyeing of the yarns is implemented, fastness of dyed colors of the yarns is improved, the color of the yarns cannot be easily faded, and the service lives of the yarns are prolonged.

Description

Technical field [0001] The invention relates to the field of yarn dyeing, in particular to a yarn dyeing process. Background technique [0002] At present, when the yarn is dyed, the yarn is usually dyed by dip-dyeing the yarn once or twice, but the color fastness of the yarn after dyeing is not high, and the yarn will fade after being used for a long time, which will affect the yarn. The use of the effect, so it becomes very important to solve this problem. Summary of the invention [0003] The purpose of the present invention is to provide a yarn dyeing process, through the first dip dyeing and steaming for the primary dye fixation, after the second dip dyeing and then adding the fixing agent to fix the color, after the fixation, dehydration, drying and baking are performed for the second time. The second fixation solves the problem that the color fastness of the dyed yarn is not high, which affects the use effect. [0004] The invention provides a yarn dyeing process, the dyein...
