Problems solved by technology

[0003] But satin also has some disadvantages, which limits its application value to a certain extent.
The special weaving process and internal structure of the satin surface make the water halo spread seriously when the satin surface meets water, which greatly affects the appearance and has certain water stains
The conventional post-finishing process can change the surface structure of the fabric to a certain extent, making it less prone to water stains when exposed to water, but the negative effects brought about by this are: the satin gloss is greatly reduced, and the handle becomes hard

preparation example Construction

[0026] The preparation method of the water-free stain printing satin finish which guarantees the luster handle comprises the following steps:

[0027] step one

[0028] Methacrylic resin (MMA) and ground hydrophobic SiO 2 The airgel nano particles are dispersed in the dispersion system to form a composite emulsion with a concentration of 20-100g / L. That is, every liter of composite emulsion contains methacrylic resin and SiO 2 The total amount of airgel nanoparticles is 20-100g. Methacrylate resin and hydrophobic SiO 2 The proportion of airgel nanoparticles is reasonably determined according to hydrophobic requirements.

[0029] The main body of the above-mentioned dispersion system is water, which contains a dispersant. In order to achieve a better dispersion effect, the dispersant includes a main dispersant and an auxiliary dispersant. The main dispersant is magnesium carbonate, and the concentration of magnesium carbonate in the composite emulsion is 0.05-0.2%. The a...

[0044] step 1

[0045] Methacrylic resin (MMA) and ground hydrophobic SiO 2 The airgel nanoparticles are dispersed in the dispersion system to form a composite emulsion with a concentration of 20g / L. That is, every liter of composite emulsion contains methacrylic resin and SiO 2 The total amount of airgel nanoparticles is about 20 g. The main body of the dispersion system is water, wherein the main dispersant is magnesium carbonate, and the concentration of magnesium carbonate in the composite emulsion is 0.05%. The auxiliary dispersant is sodium lauryl sulfate, and its concentration in the composite emulsion is 0.005%.

Abstract

The invention provides a preparation method of a water-stain-free printed satin face capable of guaranteeing gloss and hand feeling. The preparation method comprises the following steps: Step 1, dispersing methacrylic resin and aerogel nanoparticles into a dispersion system to prepare a composite emulsion; then the composite emulsion reacting at a temperature of 90-100 DEG C for 5-12 h, wherein the dispersion system contains a dispersant; Step 2, adding soft water into the composite emulsion and carrying out diluting; then adding a fluorine type strong waterproof agent and a cross-linking agent respectively and carrying out uniformly stirring; finally, adding acetic acid and a softening agent to obtain a finishing auxiliary agent; Step 3, immersing a satin face fabric into the finishing auxiliary agent; then taking out the fabric and removing the redundant finishing auxiliary agent absorbed by the fabric through a padder; and finally, drying and sizing the fabric. The preparation method provided by the invention has the beneficial effects that the high-grade texture of the satin face is guaranteed, meanwhile, the satin face has a washable super-hydrophobic effect and the problems of water spots and water stains are completely solved.

Description

technical field [0001] The invention relates to a post-processing method for fabrics, in particular to a method for preparing a water-free satin surface with glossy handle, and belongs to the technical field of textile fabrics. Background technique [0002] Satin, that is, the forging of damask satin, is the most complex technology among silk products, the most colorful fabric appearance, and the highest level of craftsmanship. The surface of satin fabric is smooth and lustrous, soft in texture, rich in color, elegant and magnificent, with national style and hometown color, and most Tang suits are made of this kind of fabric. Especially for attending some high-end banquets, the textiles made of satin are the best choice. The society is constantly developing, and people's aesthetics are also gradually changing, but their love for satin has never diminished, which can be seen from the active sales of satin in the market. [0003] But satin also has some disadvantages, which ...
