Active fabrics can be created by combining active and passive materials. Active materials with shape memory or other actuation characteristics can generate compression or dynamic fit, and the level of compression and/or change in fit can be determined by setting a knit index, wire diameter, and garment ease, or fit in relation to the body. Maximum compression can be set not only by varying physical properties of the knit structure but by built-in circuit breaking technologies, or by segmentation and control of the garment by a controller. In some embodiments, additive manufacturing can be combined with traditional textile equipment (e.g., circular knitting machine). Uniquely functional or active textiles can be made from additively manufactured, heterogeneous filaments. Yarn-like filament with varying properties (such as elasticity, stiffness, conductivity, activation, or surface properties) can be additively manufactured. This filament can be formed into a textile or garment with functional properties that are a results of emergent interactions between the heterogeneous filament components.

A heating shawl includes a shawl body and a heating element arranged inside the shawl body and configured to heat the shawl body. An outer side surface of the shawl body opposite to the heating element is provided with a contact surface, the contact surface is configured to contact with a human body. The contact surface is connected to at least one heat conducting member, and the heat conducting member is configured to conduct heat. The heating shawl provided by the present disclosure can transmit heat to the human body, fit the user's body, enhance the hot compress effect, and is easy to put on and take off, providing the user with a better use experience.
