Problems solved by technology

[0002] The jacquard cloth woven by the rapier loom has different patterns on the bad cloth, and the tightness of the patterns on the surface of the cloth is inconsistent. The place with high density is light color, and the place with relatively loose density is dark color; The ordinary printing process is used to print and dye the gray cloth, and the printing effect is mostly the same in depth, and it is impossible to make the effect that the texture of the jacquard edge position and the middle position are inconsistent in depth as required

Embodiment 1

[0020] The pretreatment is an existing conventional technology, including cloth inspection, singeing, desizing, oxygen bleaching, and mercerizing in sequence.

[0021] Alkali shrinkage: use concentrated alkali with a solubility of 400g / L to shrink the pre-treated gray cloth, so that the jacquard pattern structure is different in tightness, and the gray cloth is placed aside after alkali shrinkage.

[0022] Prepare the dyeing solution: prepare the vat dyes. Since the vat dyes are insoluble in water, the vat dyes must be pre-reduced in order to dye the gray cloth. For each pre-reduced 1g vat dyes, use concentrated alkali with a solubility of 400g / L, 85 1.5g of sodium hydrosulfite, 100mL of water, the reaction temperature is 50°C, and the reaction time is 10min. After the vat dye becomes leuco dye, its hydrophilicity can be improved.

[0023] Exhaust dyeing and water washing oxidation: place the gray cloth that has undergone alkali shrinkage in a J-shaped cylinder, that is, an in...

Embodiment 2

[0031] The pretreatment is an existing conventional technology, including cloth inspection, singeing, desizing, oxygen bleaching, and mercerizing in sequence.

[0032] Alkali shrinkage: use concentrated alkali with a solubility of 400g / L to shrink the pre-treated gray cloth, so that the jacquard pattern structure is different in tightness, and the gray cloth is placed aside after alkali shrinkage.

[0033] Prepare the dye solution: prepare the vat dyes. Since the vat dyes are insoluble in water, the vat dyes must be pre-reduced in order to dye the gray cloth. For each pre-reduced 1g vat dyes, use concentrated alkali with a solubility of 400g / L, 85% sodium hydrosulfite 1.5g, water 100mL, reaction temperature 60 ℃, time 15min, vat dye can improve its hydrophilicity after it becomes leuco dye.

[0034] Exhaust dyeing and washing oxidation: Place the gray cloth that has been shrinked by alkali in a J-shaped cylinder, that is, an inclined tube. The temperature of the J-shaped cylin...

Embodiment 3

[0042] The pretreatment is an existing conventional technology, including cloth inspection, singeing, desizing, oxygen bleaching, and mercerizing in sequence.

[0043] Alkali shrinkage: use concentrated alkali with a solubility of 400g / L to shrink the pre-treated gray cloth, so that the jacquard pattern structure is different in tightness, and the gray cloth is placed aside after alkali shrinkage.

[0044] Prepare the dyeing solution: prepare vat dyes. Since vat dyes are insoluble in water, in order to dye the gray cloth, the vat dyes must be pre-reduced. For each pre-reduced 1g of vat dyes, use concentrated alkali with a solubility of 400g / L, 85% sodium hydrosulfite 1.5g, water 100mL, reaction temperature is 56°C, time is 13min, vat dye becomes leuco dye to improve its hydrophilicity.

[0045] Exhaust dyeing and water washing oxidation: place the gray cloth that has been shrinked by alkali in a J-shaped cylinder, that is, an inclined tube. The temperature of the J-shaped cyli...

Abstract

The invention discloses a handcrafted figured cloth dyeing method with a deep-light effect. The handcrafted figured cloth dyeing method comprises the following steps in sequence: pre-treating, alkali-concentrating, preparing dyeing liquid, dip-dyeing, washing and oxidizing, scotching, soaping, tendering, calendering and baking, wherein concentrated alkali is applied to carry out alkali-concentrating before dyeing gray fabric to enable figured cloth line tightness to be more obvious, so that dyeing is promoted to achieve action of an dyeing accelerant, and therefore, degree of dyeing of the figured cloth is improved; the concentrated alkali and sodium hydrosulfite are applied to carry out pre-reduction on the reducing dye, so that the reducing dye which is insoluble in water can be dissolved in leuco body of the water, and therefore, appetency of the cotton fibers in the figured cloth is improved. According to the invention, a technical problem about how to enable the figured lines on the cloth to be inconsistent in depth can be solved.

Description

technical field [0001] The invention relates to a dyeing method for treating jacquard cloth to make the jacquard texture of the cloth have shade effect. Background technique [0002] The jacquard cloth woven by the rapier loom has different patterns on the bad cloth, and the tightness of the patterns on the surface of the cloth is inconsistent. The place with high density is light color, and the place with relatively loose density is dark color; The ordinary printing process is used to print and dye the gray cloth, and the printing effect is mostly the same in depth, and it is impossible to make the effect that the texture of the jacquard edge position and the middle position are inconsistent in depth as required. Contents of the invention [0003] The object of the present invention is to provide a hand-made jacquard dyeing method with shade effect, and to solve the technical problem of how to make the jacquard patterns on the jacquard gray fabric have the effect of inco...
