Embodiment 1

[0048] see Figure 1-2 , a digital banner cloth preparation process with high coloring rate and low water permeability, comprising the following steps:

[0049] S1. Combined warping: winding a certain number of warp yarns in parallel on the weaving beam according to the specified length and width;

[0050] S2. Shaft splicing: the warped yarns are spliced ​​according to the needs;

[0051] S3. Water-jet weaving: Water-jet looms are used to insert wefts by the jet force of high-pressure water to weave fabrics to obtain banner fabric base material 1. Since weft insertion depends on water flow, there is no hard friction during the weaving process of warp and weft filaments, and the quality of the fabric is improved. it is good;

[0052] S4. Ingredients: Weigh acrylic emulsion, natural stone powder, hydrophobic filler 201, nano-ferric oxide and dispersant to mix to obtain base layer slurry, and then weigh acrylic emulsion, polyurethane, pigment, natural stone powder, nano-SiO Fe...

Embodiment 2

[0065] The base layer slurry includes the following raw materials in parts by weight: 25 parts of acrylic acid emulsion, 18 parts of natural stone powder, 10 parts of nanometer ferric oxide and 1.3 parts of dispersant, and the surface layer slurry includes the following raw materials in parts by weight: 12 parts of acrylic acid emulsion, 10 parts of polyurethane, 12 parts of pigment, 5 parts of natural stone powder, 4 parts of hydrophobic filler 201, 8 parts of nano-ferric oxide, 1.8 parts of dispersant and 15 parts of scale-type lamination auxiliary film 301.

[0066] In step S5, the base layer slurry is first applied, dried at 90°C for 8 minutes until it is not fully cured, and then the surface layer slurry is applied at a temperature of 110°C for 20 minutes until it is completely cured to obtain a well-bonded dense base layer 2 and scale surface layer 3, improving the density of the base layer 2 and the bonding force of the scale surface 3 prevents the phenomenon of peeling ...

Embodiment 3

[0069] The base layer slurry includes the following raw materials in parts by weight: 30 parts of acrylic acid emulsion, 20 parts of natural stone powder, 12 parts of nano-ferric oxide and 1.6 parts of dispersant, and the surface layer slurry includes the following raw materials in parts by weight: 15 parts of acrylic acid emulsion, 12 parts of polyurethane, 15 parts of pigment, 6 parts of natural stone powder, 5 parts of hydrophobic filler 201, 10 parts of nano ferric oxide, 2 parts of dispersant and 20 parts of scale-type lamination aid film 301.

[0070] In step S5, the base layer slurry is first applied, dried at 00°C for 10 minutes until it is not completely cured, and then the surface layer slurry is applied at a temperature of 120°C for 25 minutes until it is completely cured to obtain a well-bonded dense base layer 2 and scale surface layer 3, improving the density of the base layer. 2 and the bonding force of the scale surface 3 prevents the phenomenon of peeling off f...

Abstract

The invention discloses a digital banner fabric preparation process with high coloring rate and low water leakiness and belongs to the technical field of banner fabric preparation. Innovative adoptionof a brand-new feeding formula can be realized, and the coloring property and the waterproof property of the banner fabric can be improved; a coating is divided into a compact base layer and a scalesurface layer for separate molding, the compact base layer has excellent coloring rate and low water leakiness while the scale surface layer introduces a scale type laminating auxiliary membrane and adopts a stacking treatment mode, and a form similar to multiple scales is formed on the surface of the compact base layer, such that pigment can be protected from being separated easily, and higher coloring rate is ensured on one hand; and on the other hand, water permeation is reduced by stacking layer upon layer, meanwhile, corresponding parts are arranged to promote the permeating water to be discharged back, further permeation to corrode the compact base layer and the banner fabric base material is avoided, water evaporation can be automatically accelerated, and a sparkling effect is formed by matching with the content of later-stage spray painting, and the overall quality and the display effect of the banner fabric are greatly improved.

Description

technical field [0001] The invention relates to the technical field of banner cloth preparation, in particular to a preparation process for digital banner cloth with high coloring rate and low water permeability. Background technique [0002] Banner cloth is one of the most widely used and the largest demanded cloth consumables, mainly used for indoor and outdoor banners, flags, curtains, scenery and so on. It is usually called "advertising cloth" because it uses synthetic fibers as the base material. [0003] The existing advertising banner cloth includes a substrate and a coating. The substrate is made of natural polymer compounds such as cellulose and protein, which are chemically processed into a polymer concentrate, and then made by spinning and post-processing. Textile fibers are woven into the base fabric; the coating is formed by mixing and stirring natural stone powder and oily PVC on the base fabric. [0004] However, the traditional digital banner cloth has a lo...
