Description

Technical Field

[0001] The present invention relates to the field of textiles, and particularly relates to a silica gel composite fabric, a preparation method thereof and an application thereof. Background Art

[0002] Silica gel is soft and has good resilience. The shoe upper containing a silica gel buffer layer can have buffering properties and good resilience. When performing strenuous exercise or being impacted by a large external force, the shoe upper with a silica gel buffer layer of a certain thickness can effectively reduce the damage of the external force to the instep, and the shoe upper can still return to its original state. The insole or sole containing a silica gel layer can also effectively absorb the impact force during walking or running through the resilience of the silica gel, reducing joint pressure.

[0003] Currently, when adding silica gel to the shoe upper, sole or insole, usually a silica gel layer is adhered with glue. However, the silica gel has a large weight, fewer surface active groups, and poor adhesion, and is likely to fall off during activities; or a method of applying silica gel liquid on the surface of the fabric and then performing a molding process by pressing is used to form a silica gel coating. However, in this treatment method, the liquid silica gel will penetrate into the fabric fibers, resulting in the fabric being airtight, and the thickness of the formed silica gel layer is limited, and the buffering is also limited.
