But in the end, it is still necessary to wash off the floating color of the dye that is not fixed on the fabric by repeated washing or soaping, which will also produce a large amount of waste water and pollute the environment.

Embodiment 1

[0025] This embodiment is a dyeing method of pad dyeing with less water and no washing, taking the dyeing of plain crepe satin with reactive dyes as an example. It includes the conventional dyeing process, that is, the steps of silk fabric pretreatment, one dipping and one padding solution, pre-drying, steaming, padding softening solution, drying and finishing. Among them, the process flow, dyeing solution formula and process conditions are as follows:

[0026] Process flow:

[0027] Fabric pretreatment→one dipping and one padding→pre-drying→steaming or baking→padding softener

[0028] Dye formula:

[0029] Dye dosage: Cibaclone reactive black - W-NN 40g / l

[0030] Adhesive and dosage: TYS (polyacrylate polymer) 80g / l

[0031] The rest is water.

[0032] Process conditions:

[0033] Squeezing rate: 80%

[0034] Infrared pre-baking (pre-baking temperature 150°C, pre-baking time 30 seconds) and then pre-baking at 80°C for 2 minutes

[0035] Steaming: temperature 105°C hu...

Embodiment 2

[0042] What this embodiment is different from above-mentioned example 1 is the less water pad dyeing and wash-free dyeing method that is the example that is dyed with liquid reactive dye of sambo satin. The specific process flow, process formula and process conditions are as follows:

[0043] Process flow:

[0044] Fabric pretreatment→one dipping and one padding→pre-drying→steaming or baking→padding softener

[0045] Dye formula:

[0046] Padding solution concentration: Ciba Black pH-RLIQ 50g / l

[0047] Adhesive and dosage: KG-101 (polyacrylate polymer) 70g / l

[0048] The rest is water.

[0049] Process conditions:

[0050] Squeezing rate: 80%

[0051] Infrared pre-baking (pre-baking temperature 250°C, pre-baking time 5 seconds) and then pre-baking at 80°C for 3 minutes

[0052] Steaming: temperature 105°C humidity 80% time 15 minutes

[0053] Softening Lotion Formula:

[0054] Softener: 40g / l

[0055] Softening process conditions:

[0056] One dipping one rolling →...

Embodiment 3

[0059] The fabric used in this embodiment is sambo satin. The specific process flow, process formula and process conditions are as follows:

[0060] Process flow:

[0061] Fabric pretreatment→one dipping and one padding→pre-drying→steaming or baking→padding softener

[0062] Dye formula:

[0063]Padding solution concentration: Ciba blue pH-RLIQ 40g / l

[0064] Adhesive and dosage: UDT (polyacrylate polymer) 60g / l

[0065] The rest is water.

[0066] Process conditions:

[0067] Squeezing rate: 80%

[0068] Infrared pre-baking (pre-baking temperature 200°C, pre-baking time 12 seconds) and then pre-baking at 80°C for 2.5 minutes

[0069] Steaming: temperature 105°C humidity 80% time 15 minutes

[0070] Softening Lotion Formula:

[0071] Softener: 40g / l

[0072] Softening process conditions:

[0073] One dipping one rolling → drying

[0074] 100°C, 2.5 minutes.

Abstract

The invention relates to a textiles dyeing method, especially to a silk facing material dyeing method. The object of the invention is to provide an improved method for silk dyeing. The invention has features of waterless or little water dyeing, reduced cost, reduced sewage water discharging and good products color fastness; the products hand feeling maintains the silk facing material special styles; and the invention is water-saving and energy-saving. The invention adopts the technical scheme: executing according to the following steps in sequence: preparing dye liquor, dyeing, pre baking, decatizing, soft liquid slop padding, drying and finishing.

Description

technical field [0001] The invention relates to a method for dyeing textiles, in particular to a method for dyeing silk fabrics. Background technique [0002] Most of the dyeing of silk fabrics is carried out in an aqueous solution of dyes with water as the medium. All kinds of fibers will expand to different degrees in the water. The dye mainly diffuses in the amorphous region of the fiber in the dispersed state of molecules (or ions), and dyes the fabric thoroughly through three stages of adsorption, diffusion and fixation. . After the dyeing is completed, the dyes that have not bonded or reacted with the fibers are adsorbed on the surface, which will affect the color fastness, so multiple washings or soaping are required. Therefore, the dyeing process is a process that consumes a lot of water, consumes energy, discharges a large amount of waste water, and pollutes the environment. [0003] At present, there have been researches on dyeing silk fabrics with paints withou...
