Embodiment 1

[0027] The preparation process of the finishing solution: according to etherified 2D resin 100g / L, magnesium chloride 30g / L, water-based polyurethane (3458) 40g / L, nanocellulose 3g / L, penetrant JFC 1g / L, softener polyethylene 30g / L Stir at 200 rpm for 4 minutes at room temperature to obtain a finishing solution.

[0028] Padding process: the cotton fabric is placed in the prepared finishing liquid for two dipping and two padding, and the padding rate is 70%-80%.

[0029] Post-treatment process: After the cotton fabric is padded with the finishing solution, it is pre-baked at 120°C for 3 minutes, then baked at 150°C for 3 minutes, washed and dried in standard water, and the treated cotton fabric is obtained.

Embodiment 2

[0031] The preparation process of the finishing solution: etherified 2D resin 100g / L, magnesium chloride 30g / L, water-based polyurethane (PSF) 40g / L, nanocellulose 3g / L, penetrant AEO 1g / L, softener polyethylene 30g / L Stir at 200 rpm for 4 minutes at room temperature to obtain a finishing solution.

[0032] Padding process: the cotton fabric is placed in the prepared finishing liquid for two dipping and two padding, and the padding rate is 70%-80%.

[0033] Post-treatment process: After padding the cotton fabric with the finishing solution, pre-bake it at 120°C for 2 minutes, then bake it at 150°C for 3 minutes, wash and dry it with standard water, and obtain the treated cotton fabric.

Embodiment 3

[0035] The preparation process of the finishing solution: etherified 2D resin 100g / L, magnesium chloride 30g / L, water-based polyurethane (BSRN) 40g / L, nanocellulose 3g / L, penetrant AEO 1g / L, softener polyethylene 30g / L Stir at 200 rpm for 4 minutes at room temperature to obtain a finishing solution.

[0036] Padding process: the cotton fabric is placed in the prepared finishing liquid for two dipping and two padding, and the padding rate is 70%-80%.

[0037] Post-treatment process: After the cotton fabric is padded with the finishing solution, it is pre-baked at 80°C for 5 minutes, then baked at 160°C for 3 minutes, washed and dried in standard water, and the treated cotton fabric is obtained.

Abstract

The invention discloses a preparation method and application of a cotton fabric non-ironing finishing liquid containing nanocellulose. The preparation method of the cotton fabric non-ironing finishing liquid comprises the step of mixing etherified 2D resin, magnesium chloride, waterborne polyurethane, nanocellulose, a penetrating agent and a softening agent to prepare the finishing liquid. The non-ironing finishing liquid has the advantages that the non-ironing finishing effect of the cotton fabric is obviously improved, the strength retention rate (greater than 65%) of the fabric is also improved, the raw material sources are convenient, the preparation process is simple and green, and the cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of textile post-finishing, in particular to a cotton fabric non-ironing finishing solution containing nanocellulose and its application. Background technique [0002] Cotton fabrics are comfortable to wear, moisture-absorbing, breathable, antistatic, and soft to the touch, but cotton fabrics are prone to deformation during wearing and washing. The unit slides relative to each other, and the hydroxyl group will generate new hydrogen bonds and rearrange in the new position. When the external force is removed, the system undergoes creep recovery. If the resistance generated by the newly formed hydrogen bond is greater than the recovery force, the system cannot recover from the deformation, and permanent deformation occurs, which seriously affects the aesthetics and comfort of the system. Therefore, non-ironing finishing is needed to improve its shortcomings. [0003] At present, the most widely used finishing...
