Description

Fabric with three-dimensional effect on surface and preparation method thereof Technical Field The invention belongs to the technical field of functional textile fabrics, and particularly relates to a fabric with a three-dimensional effect on the surface and a preparation method thereof. Background With the continuous development of textile printing and dyeing technology and the increasing of aesthetic demands of consumers, the three-dimensional decorative fabric with special visual effect and touch sense is widely applied in the fields of clothing, shoe materials, bags, home decoration and the like. The traditional three-dimensional effect of the fabric is mainly realized by the following modes: 1) Physical napping/napping, namely forming napping effect on the surface of the fabric by means of mechanical brushing, sanding and the like, wherein the method is only applicable to natural fibers or fabrics with specific tissue structures, and has single effect and poor pattern controllability. 2) The flocking process is to form a fluff layer on the surface of the fabric through electrostatic flocking, but the flocking process is complex, fluff is easy to fall off, and a fine pattern effect is difficult to form. 3) And in the foaming printing step, a chemical foaming agent is added into the printing slurry, and the slurry is foamed and raised through heating, but the foaming temperature range of the traditional chemical foaming agent is wide, the foaming multiplying power is not easy to control, the uniformity and the reproducibility of the three-dimensional effect are poor, and the foaming layer is often limited to a printing area and has insufficient bonding force with the bottom coating. 4) Thermal transfer printing, in which a pattern is transferred to a fabric surface by thermal transfer paper, but this method can only form a planar pattern, lacking in three-dimensional touch. In order to solve the problems, although the prior art has some improvements, the requirements of diversity and controllability of the three-dimensional effect (different textures such as snow frost, foaming, fluff and the like) are still difficult to meet, the flexibility and fineness of patterning treatment are good, and the durability and hand feeling comfort of the three-dimensional effect are good. Disclosure of Invention Aiming at the defects in the prior art, the invention aims to provide a fabric which realizes the accurate and controllable expansion of a printing area by introducing thermal expansion microsphere foaming powder into a synthetic resin coating and combining patterning treatment and a local hot-pressing foaming process, thereby forming a texture effect with three-dimensional sense and rich touch sense on the surface of the fabric, and simultaneously keeping the integrity and combining fastness of the coating and having the three-dimensional effect on the surface and a preparation method thereof. The technical scheme adopted for solving the technical problems is as follows: a fabric having a three-dimensional effect on a surface, comprising: A base cloth layer; a synthetic resin coating layer formed on at least one surface of the base fabric layer, the synthetic resin coating layer including a heat-expandable microsphere foam powder therein; the surface of the synthetic resin coating is provided with a printed area and a non-printed area which are formed by patterning treatment; In the synthetic resin coating of the printing area, the thermal expansion microsphere foaming powder is in an expansion state, so that the printing area protrudes on the surface of the base cloth layer relative to the non-printing area to form three-dimensional textures. Preferably, the three-dimensional texture is at least one of a frosty texture, a foamed texture, and a fluffy texture. Preferably, the synthetic resin coating is an acrylic resin coating or a polyurethane resin coating. Preferably, the patterning process is a pattern formed by any one of printing, screen printing or dyeing. Another technical problem to be solved by the present invention is to provide a method for preparing a fabric with a three-dimensional effect on a surface according to any one of the above, comprising the following steps: 1) Preparing coating sizing agent, namely mixing synthetic resin emulsion with thermal expansion microsphere foaming powder, and adding a thickening agent to adjust viscosity so that the coating sizing agent reaches a viscosity range suitable for coating; 2) Forming an undercoat layer, namely uniformly coating the coating slurry obtained in the step 1) on the surface of the base cloth through a coating machine to form a synthetic resin undercoat layer; 3) Patterning, namely patterning the coated cloth treated in the step 2) to form a preset pattern on the surface of the cloth; 4) And (3) hot-pressing foaming shaping, namely placing the cloth subjected to the patterning treatment in the step (3) into a punching die or a hot pressing ro
