Problems solved by technology

[0004] However, in this solution, when electrostatically charged droplets are sprayed and adsorbed onto the fabric, since the volume of the droplets is relatively small, and there is a certain distance from the fabric, there may be cases where the droplets fall out of the fabric, so the dyeing and finishing auxiliaries are sprayed onto the fabric. Time to be shortened
This not only makes it difficult to spray, but also causes waste of dyeing and finishing auxiliaries, so that the thickness of dyeing and finishing needs to be strengthened, which will not be conducive to the improvement of color rate and dyeing and finishing efficiency

Embodiment 1

[0045] see figure 1 , the embodiment of the present invention provides a kind of technical scheme:

[0046] A spray processing method for fabric dyeing and finishing, comprising the following steps:

[0047] S1. Use gas-assisted electrostatic atomization to break the dyeing and finishing auxiliaries into electrostatically charged micron-scale first droplets;

[0048] S2. Under the combined action of air flow, gravity and electric field force, the first droplets are sprayed onto the fabric 22 as second droplets 23 after passing through the alternating cold and heat environment, so that the second droplets 23 form microscopic droplets on the fabric 22. Scale dyeing and finishing area;

[0049] Wherein, an induced electric field is formed between the second electrostatically charged droplets 23 and the fabric 22, thereby providing the electric field force in step S2.

[0050] In this embodiment, the spraying of the first droplets into the second droplets 23 on the fabric 22 af...

Embodiment 2

[0069] see figure 2 , the embodiment of the present invention provides a technical solution, which is basically the same as Embodiment 1, with a slight difference:

[0070] This cooling includes passing through the cooled wire mesh 15 during the spraying of the first droplets onto the fabric 22 .

[0071] Specifically, the cooling part includes a metal mesh 15 , a second liquid storage tank 19 , a circulation pump 27 and a circulation pipeline 24 . The metal mesh 15 is hollow inside and is arranged in the cover body 13 . The circulation pipeline 24 , the metal mesh 15, the circulating pump 27 and the second liquid storage tank 19 constitute a circulating loop.

[0072] In this embodiment, compared with the first embodiment, the cavity ring body 4 is replaced with a metal mesh 15, and the metal mesh 15 is hollow inside, that is, it not only has dense metal meshes, but also can pass through a circulating pump. 27 The cooling liquid (such as cold water that tends to 0 ° C) con...

Embodiment 3

[0074] see image 3 , the embodiment of the present invention provides a technical solution, which is basically the same as Embodiment 1, with a slight difference:

[0075] Specifically, the spraying of the first droplets into the second droplets 23 on the fabric 22 after passing through the alternating cold and heat environment includes the following steps:

[0076] Atomizing the dyeing and finishing auxiliaries after cooling or cooling the dyeing and finishing auxiliaries into the first droplets;

[0077] spraying the first droplet towards the fabric 22;

[0078] In the process of spraying the first droplets to the fabric 22, hot air or heated and then atomized droplets of dyeing and finishing auxiliaries are injected. After becoming the second droplet 23, it is sieved through the metal mesh 15 and sprayed onto the fabric 22 evenly.

[0079] Specifically, the heating part includes a hot air blower 28 and a cavity ring body 4 which is provided in the cover body 13 and has ...

Abstract

The invention provides a spraying processing method for fabric dyeing and finishing and a spraying machine. The spraying processing method comprises the following steps: crushing a dyeing and finishing auxiliary agent into first micro-scale liquid drops with static electricity by adopting air-assisted electrostatic atomization; under the combined action of airflow, gravity and electric field force, enabling the first liquid drops to pass through a cold-hot alternating environment to become second liquid drops, spraying the second liquid drops onto the fabric, and enabling the second liquid drops to form a micro-scale dyeing and finishing area on the fabric; wherein an induction electric field is formed between the electrostatic second liquid drop and the fabric, so that the electric field force is provided. According to the invention, the spraying difficulty is reduced, and the waste of dyeing and finishing auxiliaries is also reduced, so that the dyeing and finishing thickness, the color rate and the dyeing and finishing efficiency are improved within the same time. On the basis of improving the dyeing and finishing uniformity, the deposition rate and the dyeing and finishing efficiency and reducing the energy consumption and the dyeing and finishing processing, the dyeing and finishing thickness, the dyeing and finishing color rate and the dyeing and finishing efficiency are improved in an auxiliary mode by arranging the cold and hot alternating environment area.

Description

technical field [0001] The invention relates to the technical field of fabric products, in particular to a spray processing method and a spray machine for fabric dyeing and finishing. Background technique [0002] At present, corresponding to different dyeing and finishing methods, there are various types of professional dyeing and finishing equipment, but the dyeing and finishing machines that use the traditional padding method for dyeing and finishing generally have the defects of complex structure and high energy consumption in the dyeing and finishing process. [0003] In order to solve the deficiencies of the current technology, the Authorized Bulletin No. CN101974834B discloses a spray processing method and a spray machine for fabric dyeing and finishing (hereinafter referred to as "the solution"), which adopts an air-assisted electrostatic atomization spray dyeing and finishing method. , the dyeing and finishing auxiliaries are broken into micron-scale electrostatic d...
