Problems solved by technology

[0002] The main components of the traditional non-ironing resin finishing solution contain aldehyde groups, which will volatilize formaldehyde at a certain temperature, resulting in a high content of free formaldehyde in the garment after non-ironing treatment, and it will increase with the prolongation of storage time
In addition, the limitations of the traditional garment non-ironing finishing process will also make the non-ironing shirts produced contain formaldehyde or even exceed the standard
In addition, the metal salt catalyst used in the resin finishing and the acidic substances released during the crosslinking of the methyl dihydroxyethylene urea resin will cause irreversible chlorine-absorbing embrittlement to the yarns of high-count cotton fabrics, reducing the tearing and breaking strength of the fabrics. Affect the wearing life of shirts

Embodiment 1

[0070] Taking the pure cotton 80 / 2 twill shirt as an example, use the non-iron finishing solution for ready-made shirts to finish the non-ironing finishing of finished shirts, and the steps are as follows:

[0071] Step 1. Pre-washing: remove soluble organic and inorganic impurities remaining during shirt production. Process conditions: washing temperature 40°C, washing pH 4.5-5.5, bi-directional rotary washing, rotating speed 25 rpm, washing time 20 minutes;

[0072] Step 2. Drying: Dry the pre-washed shirt until dry at 45°C;

[0073] Step 3. Finishing liquid treatment: pressurize and atomize the non-ironing finishing liquid for ready-made shirts to the tumbling shirts in a sealed environment, with a pressure of 0.5mpa, so that the liquid-carrying rate of the shirts reaches 75%; The mass percentage of the proportion is as follows: 45% crosslinking agent, 3% accelerator, 10% softener, 5% penetrating agent, and the balance is deionized water with impurity content less than 20pp...

Embodiment 2

[0082] Taking cotton-polyester 80 / 20 twill shirt as an example, use the non-iron finishing solution for ready-made shirts to finish the non-ironing finishing of finished shirts. The steps are as follows:

[0083] Step 1. Pre-washing: remove the soluble organic and inorganic impurities remaining during shirt production, process conditions: washing temperature 50°C, washing pH 4.5-5.5, bi-directional rotating washing, rotating speed 20 rpm, washing time 15 minutes;

[0084] Step 2. Drying: Dry the pre-washed shirt until dry at 45°C;

[0085] Step 3. Finishing solution treatment: pressurize and spray the no-iron finishing solution for shirt garments on the tumbled shirts in a sealed environment, with a pressure of 1mpa, so that the liquid-carrying rate of the shirts reaches 80%; The mass percentage of the ratio is as follows: 10% crosslinking agent, 0.5% accelerator, 5% softener, 1% penetrating agent, and the balance is deionized water with impurity content less than 20ppm.

Embodiment 3

[0094] Taking the pure cotton 80 / 2 twill shirt as an example, use the non-iron finishing solution for ready-made shirts to finish the non-ironing finishing of finished shirts, and the steps are as follows:

[0095] Step 1. Pre-washing: remove soluble organic and inorganic impurities remaining during shirt production. Process conditions: washing temperature 40°C, washing pH 4.5-5.5, bi-directional rotary washing, rotating speed 25 rpm, washing time 20 minutes;

[0096] Step 2. Drying: Dry the pre-washed shirt until dry at 45°C;

[0097] Step 3. Finishing liquid treatment: pressurize and atomize the non-iron finishing liquid for ready-made shirts to the tumbling shirts in a sealed environment, with a pressure of 0.8mpa, so that the liquid-carrying rate of the shirts reaches 75%; The mass percentage of the proportion is as follows: 50% crosslinking agent, 5% accelerator, 8% softener, 3% penetrating agent, and the balance is deionized water with impurity content less than 20ppm. ...

Abstract

The invention relates to a non-ironing finishing liquid for a ready-to-wear shirt. The non-ironing finishing liquid is characterized by comprising 10-50% by mass of a crosslinking agent, 0.5-5% by mass of an improver, 5-10% by mass of a softening agent and 1-5% by mass of a penetrant, with the balance being deionized water the impurity content of which is less than 20 ppm. A non-ironing finishing method for a ready-to-wear shirt by adopting the non-ironing finishing liquid is also disclosed. The method includes steps of (1) pre-washing, (2) drying, (3) processing with the non-ironing finishing liquid, (4) drying to certain humidity, (5) finishing and ironing, (6) baking, (7) allowing the ready-to-wear shirt to stand, (8) washing again, and (9) drying. Through the non-ironing finishing liquid and the method, non-ironing shirts are free of formaldehyde really, the content of free formaldehyde meets the undetected grade of the textile product formaldehyde testing national standard GB/T2912.1-2009, crease resistance of shirts is improved, and the appearance of a finished shirt is made durable.
