Problems solved by technology

Although the components of the finishing liquid used in this method will not directly produce formaldehyde, the modified dihydroxymethyl dihydroxy ethylene urea and modified alkyl dihydroxy ethylene urea resin used will indirectly produce formaldehyde during the thermal reaction process, resulting in The formaldehyde content of garments is unstable and cannot be truly formaldehyde-free
Moreover, the final cooling step of the process cannot completely volatilize the residue of the finishing solution, and the unreacted reagent will cause certain irritation to the wearer with sensitive skin
[0003] In addition, high-temperature and high-humidity environments will speed up metabolism and perspiration, and sweaty shirts will become a breeding ground for bacteria. The reproduction and metabolism of bacteria will produce unpleasant body odor, affecting the comfort and health of the wearer. At the same time, the number of bacteria increases It will also damage the texture of the shirt and reduce the wearing life of the shirt

Embodiment 1

[0030] Taking the pure cotton 80 / 2 twill shirt as an example, the steps are as follows:

[0031] (1) Pre-washing: remove the soluble organic and inorganic impurities remaining during shirt production, wash at 40°C, adjust the pH of washing to 4.5-5.5 with citric acid, and wash in two-way rotation at a speed of 25 rpm for 20 minutes;

[0032] (2) Drying: Rotate the pre-washed shirt in both directions at 45°C until dry;

[0033] (3) Finishing liquid treatment: The finishing liquid is atomized and sprayed onto the tumbled shirts through a closed atomization device, so that the liquid-carrying rate of the shirts reaches more than 85%. The components of the finishing liquid in this embodiment include by mass percentage: 45% cross-linking agent, 3% zinc acetate, 10% polyethylene dispersion, 5% silver ion antibacterial agent, and the balance is deionized water with an ion content less than 20ppm. The molecular formula of the cross-linking agent is C 23 h 17 N 6 FO (BASF, Germany),...

Embodiment 2

[0044] Taking the pure cotton 80 / 2 twill shirt as an example, the steps are as follows:

[0045] (1) Pre-washing: remove the soluble organic and inorganic impurities remaining during shirt production, wash at a temperature of 50°C, adjust the pH of washing to 4.5 to 5.5 with citric acid, and wash in two directions at a speed of 30 rpm for 25 minutes;

[0046] (2) Drying: Rotate the pre-washed shirt in both directions at 50°C until dry;

[0047] (3) Finishing liquid treatment: The finishing liquid is atomized and sprayed onto the tumbled shirts through a closed atomization device, so that the liquid-carrying rate of the shirts reaches more than 85%. The components of the finishing liquid in this embodiment include by mass percentage: 35% crosslinking agent, 4% ammonium chloride, 8% polyethylene dispersion, 12% silver ion antibacterial agent, and the balance is deionized water with an ion content less than 20ppm. The molecular formula of the crosslinking agent is C 23 h 17 N ...

Embodiment 3

[0058] Taking the pure cotton 80 / 2 twill shirt as an example, the steps are as follows:

[0059] (1) Pre-washing: remove the soluble organic and inorganic impurities remaining in the production of shirts, wash at 40°C, adjust the pH value of washing with citric acid to 4.5-5.5, rotate in both directions, rotate at 10 rpm, and wash for 30 minutes;

[0060] (2) Drying: Rotate the pre-washed shirt in both directions at 60°C until dry;

[0061] (3) Finishing liquid treatment: The finishing liquid is atomized and sprayed onto the tumbled shirts through a closed atomization device, so that the liquid-carrying rate of the shirts reaches more than 85%. The components of the finishing liquid in this embodiment include by mass percentage: 50% crosslinking agent, 5% sodium citrate, 5% polyethylene dispersion, 25% silver ion antibacterial agent, and the balance is deionized water with an ion content less than 20ppm. The molecular formula of the crosslinking agent is C 23 h 17 N 6 FO (B...

Abstract

The invention relates to formaldehyde-free anti-bacterial noniron finish liquid of a shirt. The formaldehyde-free anti-bacterial noniron finish liquid comprises the following components by weight percent: 30-50% of a crosslinking agent, 3-5% of a catalyst, 5-10% of a softening agent, 5-30% of a silver ion anti-bacterial agent and the balance being deionized water with the impurity content less than 20ppm, wherein the molecular formula of the crosslinking agent is C23H17N6FO. The invention also provides a formaldehyde-free anti-bacterial noniron finish method comprising the following steps of prewashing a ready-to-wear shirt, drying, treating by a finish liquid, drying with constant humidity, carrying out press-ironing, baking, carrying out static equilibrium, backwashing the ready-to-wear shirt and drying. The obtained shirt has excellent crease-resistant, washing-resistant and anti-bacterial performances, meanwhile does not contain formaldehyde, and is environmentally friendly, natural and healthy.

Description

technical field [0001] The invention relates to a non-iron finishing solution and a finishing method for fabrics, in particular to a formaldehyde-free antibacterial and non-ironing finishing solution and a finishing method for shirts. Background technique [0002] The main components of traditional non-ironing resin finishing liquids contain aldehyde groups, which will volatilize formaldehyde at a certain temperature, resulting in a high content of free formaldehyde in garments after non-ironing treatment, and it will increase with the prolongation of storage time. In addition, the imperfection of the traditional garment non-ironing finishing process will also cause the non-ironing shirts produced to contain formaldehyde or even exceed the standard. Media reports on formaldehyde in non-ironing shirts have left consumers with a shadow of formaldehyde in their impression of non-ironing shirts. People not only favor the comfortable feel of ready-made non-ironing shirts and the ...
