Example Embodiment

[0019] Example 1:

[0020] Take 25 bags of 15N pure linen yarn (5Kg each) dyed into dark blue linen yarn as an example.

[0021] A) Wet the skein yarn, first put the flax yarn skein into the sarong evenly, and hoist the sarong into a semi-filled dyeing vat such as that produced by Hong Kong Lixin Co., Ltd. The hot water temperature in the dyeing vat is 90℃, open Pump, soak the yarn for 20 minutes, and then drain to get wet linen yarn;

[0022] B) Dyeing, temporarily hoist the sarong out of the dye vat, pour water into the dye vat with a bath ratio of 1:15, and then add bone glue 4g / L to the dye vat to reduce the dark blue BO2.1% (OWF) and the reduced olive green B3.5% ( OWF) and reduced bleaching blue BC1.6% (OWF), use 400 liters of hot water at 60°C to heat the material, and then add the material to the dye vat. Add 7g / L of caustic soda with a purity of 100% to the dye vat and add purity of 85% Sodium Sulfate 5-6g / L, heat the dyeing bath to 55°C, turn on the pump and mix evenly, ...

Example Embodiment

[0029] Example 2:

[0030] A) For the 24N pure Asian yarn, 25 packages of hemp yarn (5Kg per package) are dyed into light yellow linen yarn as an example.

[0031] The hank is wet with water, the temperature of the hot water is changed to 86℃, and the soaking time is changed to 30min;

[0032] B) For dyeing, change the bath ratio to 1:12, the added amount of bone glue to 4.5g / L, and the dye to use Vat Yellow G0.092% (OWF), Vat Olive R0.0096% (OWF) and Vat Brown G0 .0074% (OWF), using 15 liters of hot water at 55°C, the amount of caustic soda added is changed to 2-2.5g / L, the amount of sodium hydroxide added is changed to 2-2.2g / L, and the temperature rise of the dye bath is changed. It is 60℃, keep it at 60℃ for 25min;

[0033] C) Acid neutralization, only the amount of glacial acetic acid added is changed to 0.5g / L, and the pumping treatment time is changed to 6min;

[0034] D) Aging treatment, only the stacking time is changed to 8h;

[0035] E) Soaping, only change the soaping ...

Example Embodiment

[0039] Example 3:

[0040] A) For the 24N pure Asia, 25 packs of hemp yarn (5Kg per pack) dyed into bluish gray linen yarn as an example.

[0041] The skein is wet with water, the temperature of the hot water is changed to 96℃, and the soaking time is changed to 11min;

[0042] B) For dyeing, change the bath ratio to 1:20, the added amount of bone glue to 4.2g / L, and the dye to use vat ash M1.16% (OWF), vat brown BR 0.3% (OWF) and vat dark blue BO0.05% (OWF), using 120 liters of hot water at 55°C, the amount of caustic soda added is changed to 8.5g / L, the amount of sodium hydroxide added is changed to 2.5-3g / L, and the temperature of the dye bath heating temperature is changed to 65 ℃, keep at 65℃ for 40min;

[0043] C) Acid neutralization, only the added amount of glacial acetic acid was changed to 1.5g / L, and the pumping treatment time was changed to 13min;

[0044] D) Aging treatment, only the stacking time is changed to 6h;

[0045] E) Soaping, only change the soaping temperatu...

Abstract

A dyeing method of a linen yarn belongs to the technical field of textile fiber. The method comprises the following steps: reeling and wetting the yarn; dyeing; neutralizing with acid; performing ageing treatment; soaping; and performing softening treatment. The technical scheme is as follows: the method can ensure that a surface of the linen yarn is adequately dyed, and a core is not dyed, and ensure high color fastness, ideal chlorine bleach resistance, light resistance and soaping resistance of the linen yarn, thus a linen material woven by the linen yarn which is dyed by the method can have a jean style with worn feeling and obscurity, and the linen which is a colored woven fabric shows color and luster effects as colored spun fabric, which satisfies color and luster requirements of humans for fading colored woven fabric made of the linen yarn.

Description

technical field [0001] The invention belongs to the technical field of textile fiber dyeing, in particular to a method for dyeing flax yarn. Background technique [0002] Regarding the dyeing of flax yarn, the applicant searched and only retrieved the Chinese invention patent authorization announcement number CN1062619C. The technical scheme recommended by this patent is: pretreat the flax roving after bleaching, then wash it with water, dye it again, and finally Wash again. The raw materials used for pretreatment are SD, JFC, sodium sulfite, sodium carbonate, sodium hexametaphosphate and M80. The above-mentioned raw materials are put into the water tank and treated at 30-65°C for 15-25min under normal pressure; water washing is carried out under normal pressure at 45 Washing at -60°C for 15-30min; dyeing is under normal pressure, dyeing flax roving in a dyeing bath at 45-95°C for 30-90min; washing again is under normal pressure at 30-60°C 15-30min. Obviously, the above-m...
