[0041] Prepare 2-tetradecenyl-1-sodium sulfonate with different contents (0~6wt%), sodium alginate 2wt%, sodium bicarbonate 3wt%, ethylene glycol 1wt%, 2-methyl-4-isothiazoline -3-ketone 0.5wt% and m-nitrobenzenesulfonate sodium 0.5wt% pretreatment agent: 3g sodium bicarbonate, 1g ethylene glycol, 0.5g 2-methyl-4-isothiazoline-3-one and 0.5g of sodium m-nitrobenzenesulfonate are completely dissolved in 86-93g of distilled water, and 0-6g of 2-tetradecenyl-1-sodium sulfonate with an active ingredient of 35% is added, and the process is carried out at a speed of 300r / min. Stir, and pour 2g of sodium alginate slowly during the stirring process, stir for 2 hours, and then obtain the pretreatment agent used after it is uniformly dissolved.

[0042] Use the P-B0 horizontal padding machine to pad the prepared pretreatment solution onto the cotton / polyamide fabric to be treated respectively, and the pressure on both sides of the roll is 0.1kg / cm 2 , the roll speed is 12r / min, and the...

Embodiment 2

[0053] Prepare sodium alginate with different contents (0-3wt%), 5wt% sodium 2-tetradecenyl-1-sulfonate, 3wt% sodium bicarbonate, 1wt% ethylene glycol, 2-methyl-4-isothiazoline -3-ketone 0.5wt% and m-nitrobenzene sodium sulfonate 0.5wt% pretreatment agent: 3g sodium bicarbonate, 1g ethylene glycol, 0.5g2-methyl-4-isothiazolin-3-ketone and Dissolve 0.5g of sodium m-nitrobenzenesulfonate completely in 87-90g of distilled water, add 5g of AOS solution with an active ingredient of 35%, and stir at a speed of 300r / min. During the stirring process, slowly dissolve 0-3g of sodium alginate Pour slowly, and the pretreatment agent used will be obtained after it is uniformly dissolved.

The padded f...

Embodiment 3

[0061] Prepare sodium alginate 2wt%, 2-tetradecenyl-1-sodium sulfonate 5wt%, sodium bicarbonate 3%, ethylene glycol 1wt%, 2-methyl-4- The pretreatment solution of 0.5wt% of isothiazolin-3-ketone and 0.5wt% of m-nitrobenzene sodium sulfonate uses the P-B0 horizontal padding machine to pad the prepared pretreatment solution to cotton / polyamide fabrics, On pure cotton fabric and pure polyamide fabric, the pressure on both sides of the roll is 0.1kg / cm 2 , the roll speed is 12r / min, and the liquid carrying rate of the fabric is (75±1)%. The fabric after padding is dried at 100° C. to obtain the treated fabric to be printed. Inkjet printing was carried out on the treated fabric according to the second part of Example 1.

Abstract

The invention discloses a cotton / polyamide fabric inkjet printing pretreatment agent and a pretreatment process, wherein the pretreatment agent comprises the following components in terms of mass percentage, water-soluble high molecular polymer 0.5-3%, surfactant 1 ~6%, pH adjuster 1~5%, and the balance is water; the treatment process is characterized in that the above pretreatment agent is applied to the surface of cotton / polyamide fabric by one-bath padding, and then dried. The invention can effectively improve the apparent color yield depth of the two fibers on the cotton / polyamide fabric through a simple process of the one-bath method, and obviously improve the pattern definition, color homogeneity, rubbing fastness and washing fastness of digital printing products, At the same time, the present invention significantly reduces the cost and energy consumption in the pretreatment process due to the simple technological process and simple operation.

Description

technical field [0001] The invention belongs to the technical field of blended / interwoven fabric printing, and in particular relates to a cotton / polyamide fabric inkjet printing pretreatment agent and a pretreatment process. Background technique [0002] Cotton / polyamide fabric not only maintains the advantages of high strength, good elasticity, non-wrinkle, and lightness of nylon fiber, but also maintains the simple texture of cotton fabric. It is an ideal fabric for current fashion and high-end clothing. However, due to the differences in the surface structure and properties of cellulose fibers and polyamide 6 fibers, the cotton / polyamide fabrics printed with reactive dyes have low color depth, poor color matching, and poor color fastness. [0003] In order to prevent pattern bleeding on the surface of the fabric and to apply alkali and other auxiliary agents required for dyeing, the surface of the fabric is usually pretreated or modified before inkjet printing. Common met...
