The technical effects and advantages of the present invention: through the modification of the burnt-out velvet fabric with polycarboxylic acid, the polyester fiber is loaded with carboxyl groups, nano-titanium dioxide and plasma composite finishing, and the comfortable and health-care burnt-out velvet fabric with hydrophilicity and antibacterial properties can be obtained .

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The invention provides an antibacterial and hydrophilic treatment process for burnt-out velvet fabrics, which specifically includes the following steps:

S1, preparing modified polycarboxylic acid and cross-linking the fabric;

S2, preparing a titanium dioxide finishing agent and padding the fabric;

S3, using a plasma dryer to dry the fabric;

In step S1, the modified polycarboxylic acid is formed by mixing various polycarboxylic acids, chitosan, and sodium hypophosphite, and acts at 190°C for 90s;

In step S2, the titanium dioxide finishing agent is prepared by a sol-gel method, and is prepared from butyl titanate, absolute ethanol, glacial acetic acid, and deionized water as raw materials.

In the present invention, through the synergistic effect of multiple polycarboxylic acids, the wrinkle elasticity of the fabric can be greatly improved, and the copolymers of various carboxylic acids can also provide more free carboxyl groups when they are firmly cross-linked with cellulose, It is beneficial to the adsorption of chitosan, and the better adsorption of chitosan can ensure the hydrophilic performance of the fabric, and make the fabric have better washability. At the same time, the titanium dioxide finishing agent makes the fabric have better antibacterial performance. So that the fabric has better performance in terms of antibacterial and hydrophilic.

In the present invention, as a preferred solution, in step S2, the fabric is preferentially de-ironed.

In the present invention, the fabric is ironed, so that the subsequent polycarboxylic acid and titanium dioxide can be better adsorbed on the fabric, thereby ensuring the hydrophilic and antibacterial properties of the fabric.

In the present invention, as a preferred solution, the ironing treatment steps of the above-mentioned fabric are as follows:

A. Soak the fabric;

B. Semi-dry the soaked fabric at 90°C, and the fabric is in a semi-wet state at this time;

C. Iron the semi-wet fabric under the ironing machine.

In the present invention, when the fabric is ironed from a semi-wet state, more water vapor will be generated during the ironing process, and this water vapor will cover the fabric so that the fabric has a better ironing effect.

In the present invention, as a preferred solution, in step C, the ironing machine performs ironing treatment on the front and back sides of the fabric in a semi-wet state, respectively.

In the present invention, the front and back sides of the fabric are ironed to ensure that the front and back sides of the fabric are in a flat state, thereby ensuring that the polycarboxylic acid and titanium dioxide have a better adsorption effect on the front and back of the fabric.

In the present invention, as a preferred solution, the molar ratio between the above-mentioned butyl titanate, absolute ethanol, glacial acetic acid, and deionized water is: 1:25:5:0.5, after being sealed and aged for 15 hours, the Calcined at 450°C to obtain titanium dioxide powder.
