A kind of 3D three-dimensional printing fabric and preparation method thereof

Abstract

The invention provides a preparation method of 3D three-dimensional printing fabric, comprising the following steps: preparation of foaming coating: firstly formulating water-based polyurethane resin, foaming agent and auxiliary agent into a base material, then adding a curing agent to foam for 7-9min, Add color paste and foam for 1-3min to prepare foamed coating; the mass ratio of the water-based polyurethane resin, foaming agent and curing agent is 90-110:3-5:2-3; the foaming agent includes Fatty acid ammonium salt foam accelerator and sulfosuccinamide sodium salt surfactant; screen printing: the prepared foam coating is printed on the base surface of the cloth through a screen plate within 30min; The thickness is 2‑4mm; curing: drying and curing the coated fabric to obtain a 3D three-dimensional printed fabric. In the technical solution, the foamed coating has strong permeability to the substrate, can form a firm structure during the film forming process, has strong adhesion and is extremely difficult to fall off; at the same time, the coating has a soft touch, good flexibility, wear resistance, Impact resistance and other properties, in the process of use, the coating is not easy to break.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a 3D three-dimensional printing fabric and a preparation method thereof. Background technique [0002] At present, polyamide or acrylic paste is mostly used in shoe upper printing. Generally, 60-120 mesh screen is used. Through several to dozens of screen printing, superimposed coating is prepared to realize printing design and various effects. 3D effect printing. However, the traditional screen printing process is not easy to prepare thick superimposed coatings. Up to 30 printing processes are required for the thickness of superimposed coatings to reach 1mm. Therefore, the thickness of 3D printing is generally 0.6-1.2mm. Over 1.2mm of superimposed coating, the coating is stiff, and the coating is prone to cracking and falling off after a little bending. In addition, the flexibility of the superimposed coating is insufficient, and the impact resistance is insufficient. During intense sp...

Problems solved by technology

However, the traditional screen printing process is not easy to prepare a thick superimposed coating. Up to 30 printing processes are required to achieve a thickness of 1mm. Therefore, the thickness of 3D printing is generally 0.6-1.2mm.

Overlay coatings over 1.2mm, the coating is stiff, and the coating is prone to cracking and falling off when slightly bent, which is not suitable for the processing of shoe uppers, and the coating and coating are also prone to cracking

In addition, the superimposed coating is not flexible enough, and the impact resistance is insufficient. When performing more intense sports, such as playing football, the surface coating is easily broken under the action of impact external force, which reduces the service life of the shoes.
