Memory ironing-free foldable composite material suitable for apparels, manufacturing method thereof and application thereof

A memory ironing-free foldable composite material suitable for apparels, comprising:

• at least seven layers of materials;
• wherein a fourth layer as a middle layer is a silica gel layer, a third layer and a fifth layer respectively adjacent to two opposite sides of the middle layer are adhesion layers, a second layer located outside the third layer is a substrate composite layer, a sixth layer located outside the fifth layer is another substrate composite layer, a first layer located outside the second layer is a cover layer, and a seventh layer located outside the sixth layer is a lining layer;
• wherein the first layer, the second layer, the third layer, the fourth layer, the fifth layer, the sixth layer and the seventh layer are sequentially arranged in that order and directly connected with each other;
• wherein the silica gel layer is one selected from the group consisting of a silica gel mesh, a silica gel sheet and a silica gel roll and made of a SiO2·nH2O material;
• wherein the cover layer is a non-stick paper, and the non-stick paper is a silicone oil release paper;
• wherein each of the sixth layer and the second layer comprises a polymer double-sided adhesive layer;
• wherein a material of each of the adhesion layers is a surface treatment agent for silica gel, and the surface treatment agent for silica gel is a combination material comprising a coupling agent;
• and
• wherein a material of the lining layer is a non-stick paper, and the non-stick paper is a silicone oil release paper.
