Printing technology of hydrophobic fabric

Abstract

The invention discloses a printing technology of hydrophobic fabric and relates to the technical field of printing of hydrophobic fabric such as polyamide and polyester. According to the printing technology disclosed by the invention, the hydrophobic fabric after desizing passes through a plasma atmosphere at a constant speed, and then the fabric after the pretreatment is printed; since the plasmahas energy and reaction activity, by striking the fabric surface with the plasma particles, an active group is generated on the fabric surface; after the active group is rearranged, a new hydrophilicgroup is generated on the fabric surface, thus the color absorption property of the fabric can be greatly improved, and the range of optional thickening agents is widened.

Description

technical field

[0001] The invention relates to the technical field of printing of hydrophobic fabrics such as nylon and polyester. technical background

[0002] Synthetic fibers such as polyester, nylon, acrylic, polypropylene, and vinylon have smooth surfaces, dense structures, and poor hydrophilicity. Such fabrics are called hydrophobic fabrics in the industry. In its printed products, it is necessary to ensure the clear outline of the pattern and to make the printed fabric have a high color yield, so the requirements for thickeners are different from those for cotton and other fabrics. Natural materials such as thickener sodium alginate and starch used in cotton fabric printing have strong water holding properties, and their application in the printing of hydrophobic fabrics formed by weaving synthetic fiber fabrics cannot obtain ideal printing effects.

[0003] At present, most of the thickeners used in synthetic fibers are synthetic thickeners. Their extensive use has...

Examples

Embodiment 1

[0021] 1. Plasma pretreatment process:

[0022] The desized fabric was treated in a plasma atmosphere at 3×10 -3 The running speed of m / s passes through at a constant speed.

[0023] Wherein, the carrier of the plasma atmosphere is a mixed gas of helium and nitrogen, the flow rate of helium is 15 LPM, and the flow rate of nitrogen is 0.3 LPM.

[0024] Power supply: 30W.

[0025] 2. Printing process:

[0026] Dye formula: acid dye deep blue R 10g / L, sodium alginate 2g / L, sodium carboxymethylcellulose 3g / L, urea 50g / L, glacial acetic acid 0.008g / L.

[0027] Dye temperature: 100-102°C.

[0028] Print the pretreated fabric with a liquor ratio of 1:10 for 20 minutes.

[0029] 3. Soaping process:

[0030] Soap the printed fabric.

[0031] Among them, soaping agent: JD 1g / L, soaping temperature: 65°C, time: 20min.

[0032] 4. Fixing process:

[0033] Fix the soaped fabric.

[0034] Among them, color fixing agent: MPT 4%owf, color fixing temperature: 70°C, time 30min.

Embodiment 2

[0036] Other processes are the same as in Example 1, except that the thickener is changed from 2 g / L of sodium alginate and 3 g / L of sodium carboxymethyl cellulose to 1 g / L of sodium alginate and 4 g / L of sodium carboxymethyl cellulose.

Embodiment 3

[0038] Other processes are the same as in Example 1, except that the thickener is changed from sodium alginate 2g / L and carboxymethyl cellulose sodium 3g / L to sodium alginate 3g / L and carboxymethyl cellulose sodium 2g / L.
