Embodiment 1

[0020] Take 25 packs of 15N pure linen yarns (5Kg in every bag) to dye dark blue linen yarns as example.

[0021] A) Skein wet water, first put the flax yarn skein evenly into the sarong, and hang the sarong into a semi-filled dyeing vat such as produced by Hong Kong Lixin Co., Ltd., the temperature of the hot water in the dyeing vat is 90 ° C, start Pump to soak the yarn for 20 minutes, then drain water to obtain wet water linen yarn;

[0022] B) Dyeing, temporarily hang the sarong out of the dyeing vat, pour water into the dyeing vat, the bath ratio is 1:15, then add bone glue 4g / L to the dyeing vat, reduce the dark blue BO2.1% (OWF), and reduce the olive green B3.5% ( OWF) and reduced bleaching blue BC1.6% (OWF), with 400 liters of hot water chemical material of 60 ℃, join in the dye vat behind the chemical material, add in the dye vat that purity is 100% caustic soda 7g / L and adding purity is 85% sodium hydrosulfite 5-6g / L, raise the temperature of the dyeing bath to 55°C...

Embodiment 2

[0030] A) 24N pure linen yarn dyed light yellow linen yarn with 25 packs (5Kg per pack) as an example.

[0031] Skein wet water, change the temperature of the hot water to 86°C, and the soaking time to 30 minutes;

[0032] B) For dyeing, change the bath ratio to 1:12, change the amount of bone glue to 4.5g / L, and use vat yellow G0.092% (OWF), vat olive R0.0096% (OWF) and vat brown G0 as dyes .0074% (OWF), with 15 liters of hot water at 55 ℃, the addition of caustic soda is changed to 2-2.5g / L, the addition of sodium hydrosulfite is changed to 2-2.2g / L, and the heating temperature of the dyeing bath is changed to 2-2.5g / L. 60°C, keep warm at 60°C for 25 minutes;

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

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

[0035] E) Soaping, only change the soaping temperature to 85°C, the soaping time to 12min, the amount o...

Embodiment 3

[0040] A) 24N pure linen, take 25 packs of linen yarn (5Kg per pack) dyed blue-gray linen yarn as an example.

[0041] For skein wet water, change the temperature of the hot water to 96°C and the soaking time to 11 minutes;

[0042] B) For dyeing, change the bath ratio to 1:20, change the amount of bone glue to 4.2g / L, and use reduced gray M1.16% (OWF), reduced brown BR0.3% (OWF) and reduced dark blue as dyes. BO0.05% (OWF), use 120 liters of hot water at 55 ℃ to change the material, the amount of caustic soda added is changed to 8.5g / L, the amount of sodium hydrosulfite added is changed to 2.5-3g / L, and the heating temperature of the dyeing bath is changed to 65 ℃, keep warm at 65℃ for 40min;

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

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

[0045] E) Soaping, only change the soaping temperature to 92°C, the soa...

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...
