Abstract

The present invention relates to a functional fabric, comprising: a substrate layer, said substrate layer including a cloth and a functional layer on said substrate layer, said functional layer including a silica gel masterbatch and anion additives, and having a three-dimensional configuration, wherein said functional layer has a thickness such that said functional fabric is capable of releasing a concentration of 1,000-6,000 anions per cubic centimeter.

Claims

1. A 3D printing method for manufacturing a functional fabric, comprising the following steps:

(a) providing a cloth as a substrate layer of the functional fabric;

(b) modeling a functional layer of the functional fabric on computer;

(c) providing, melting and mixing a silica gel masterbatch and anion additives, and

(d) 3D printing the functional layer on the substrate layer using a 3D printer.

2. The 3D printing method according to claim 1, further comprising the following step:

(e) providing one or more additional additives of heat-releasing materials, far-infrared materials, antibacterial materials, aromatic materials and reinforcing materials, the additional additives are melted separately or mixed and melted together with silica gel masterbatch and anion additives, and supplied to the 3D printer.

3. The 3D printing method according to claim 1, further comprising the following step:

(f) printing on different locations of the substrate layer a functional layer of varying thickness and/or varying configurations and/or varying components.
