Embodiment 1

[0029] Embodiment 1: light color (dye consumption X≤1%) printing

[0030] (1) Printing process, as shown in Figure 1:

[0031] (2) Formula and process description:

[0032] 1) Pretreatment (Silk Fiber Graft Modification) formula and process:

[0033] Grafting agent 205: about 30g / L, two dipping and two rolling (at room temperature, 70-80% liquid), and drying at 105-120°C (3-5min).

[0034] Grafting agent 205 was provided by Zhejiang Huasheng Chemical Co., Ltd.

[0035] 2) Color paste formula and instructions:

[0036] Acid or neutral dyes: ≤1%, urea: about 1%, 3% synthetic thickener slurry: 50-70% (under the premise of ensuring that the printing does not bleed, the synthetic thickener slurry should be as little as possible), add water to 100 %.

[0037] Due to the low amount of dye used, there is less floating color after printing and steaming, and generally no washing and desizing are required. Therefore, the paste in the color paste is all made of synthetic thickener p...

Embodiment 2

[0041] Embodiment 2: medium depth (dye consumption X is 1~3%) printing

[0042] (1) printing process, as shown in Figure 2:

[0043] (2) Formula and process description:

[0044] 1) Pretreatment (Silk Fiber Graft Modification) formula and process:

[0045] Grafting agent 205: about 40 g / L, two dipping and two rolling (at room temperature, 70-80% liquid), and drying at 105-120°C (3-5min).

[0046] 2) Color paste formula and instructions:

[0047] Acidic or neutral dyes: 1-3%, urea: about 2%, 3% synthetic thickener pulp: 40-60%, 6% modified sodium alginate pulp: about 10-15% (to ensure that the printing does not bleed Under the premise, the amount of synthetic thickener and sodium alginate pulp should be as little as possible), and add water to 100%.

[0048] Modified sodium alginate is to add 2-3% of anionic detergent (such as cleaning agent 209) to sodium alginate pulp. The detergent can wet and expand the serous film and improve the water washability of the pulp.

Embodiment 3

[0053] Embodiment 3: dark color (dyes consumption X is 3~5%) printing

[0054] (1) printing process, as shown in Figure 3:

[0055] (2) Formula and process description:

[0056] 1) Pretreatment (Silk Fiber Graft Modification) formula and process:

[0057] Grafting agent D: about 50g / L, two dipping and two rolling (at room temperature, with 70-80% liquid), and drying at 105-120°C (3-5min).

[0058] Grafting agent D was provided by Hangzhou Kefeng Chemical Co., Ltd.

[0059] 2) Color paste formula and instructions:

[0060] Acid or neutral dye: 3-5%, urea: about 3%, 4% synthetic thickener pulp: 40-50%, 8% modified corn or konjac starch (plant seed glue) pulp: about 15-20% (On the premise of ensuring that the printing does not bleed, the amount of synthetic thickener and sodium alginate pulp should be as little as possible), strengthening agent 201: 1-5%, softener: 1-5%, add water to 100%.

[0061] Due to the high amount of dye used, the fabric after printing and steaming cont...

Abstract

The invention discloses a real silk fabric dye art fine water laundering stamping, which is characterized by the following: proceeding graft modify for real silk fibre; introducing basic ion group into fabric molecule; intensifying dye seat of negative ion (acid, neutral and so on); intensifying dye-uptake of the dye; improving color stability; adopting synthetic thickener with low solid content as main primary pulp of dye art color paste; decreasing the content of slurry in color paste; adding reinforce agent and soften agent into color paste; further-improve color stability of printing textile; modifying hand touch. This invention can shorten dye printing craft, which can reach the goal of light wash.

Description

technical field [0001] The invention relates to a textile printing method, in particular to a light washing printing method for silk fabric dye printing. Background technique [0002] At present, there are two types of silk fabric printing: pigment printing and dye printing. [0003] Pigment printing is widely used, accounting for about 50-60% of the entire printing production; pigment printing is a printing process that uses adhesives to form a film on the fabric, thereby fixing the paint on the surface of the fabric to obtain the desired pattern. It has the advantages of simple operation, simplified process, generally no washing, soaping, desizing and other processes after printing, energy saving, and no waste water problem. However, pigment printing relies on an adhesive to form a film to adhere it to the fabric. Due to the existence of the adhesive, the printed (especially large-area printed) fabric has a poor feel, and the film formed by the adhesive on the pattern par...
