Provided herein are a controllable liquid transport material, a controllable liquid transport system and a method for preparing a controllable liquid transport material, where a first region of the controllable liquid transport material is treated to be hydrophobic, while a plurality of second regions partially contacted or completely separated with different shapes are treated to have a gradient or varied wettabilities and/or pore sizes for passively controllable liquid transport, and/or integrated with a smart material for actively controllable liquid transport driven by an external force, allowing efficiently and controllably directional transport of a liquid e.g., sweat. The controllable liquid transport system comprises a controllable liquid transport material used as a liquid transport layer and a breathable, waterproof protective layer.

Disclosed is a skin cooling fabric that can provide a user with a soft tactile sensation as well as a cooling feeling or a cooling sensation, a polyethylene yarn having improved weavability, and a method for manufacturing the yarn. The skin cooling fabric of the present invention includes a plurality of weft yarns, and a plurality of warp yarns, wherein each of the weft yarns and warp yarns has a tensile strength of 3.5 to 8.5 g/de, a tensile modulus of 15 to 80 g/de, elongation at break of 14 to 55%, and crystallinity of 55 to 85%.

A thermoelectric module includes two insulating substrates supporting a plurality of thermoelectric fingers.

A heat-generating fabric contains an modacrylic fiber A and an animal hair fiber. The modacrylic fiber A contains an infrared absorber inside of the fiber, in an amount of 1 to 30% by weight with respect to the total weight of the modacrylic fiber, and the fabric has a heat-shielding rate of less than 40% as measured according to JIS L 1951:2019. The heat-generating fabric contains a first yarn and a second yarn whose fiber composition is different from that of the first yarn. The first yarn may contain the modacrylic fiber A, and the second yarn may contain the animal hair fiber. Accordingly, it is possible to provide a fabric with good heat-generating performance and durability, and a textile product containing the fabric.
