Definitions

  • FIELD [0003] The present disclosure relates to articles of manufacture with improved moisture management, as well as methods related thereto.
  • Perspiration is the primary means of thermoregulation for the human body, during which sweat (mainly composed of water) is secreted through the skin and evaporation of the fluid removes the heat from the surface underneath. Without efficient sweat removal during intensive activity, accumulated sweat can drastically increase the humidity level surrounding the skin, resulting in a very uncomfortable feeling.
  • Active wear which uses highly-wicking fabric, has been the current standard solution for removing sweat from the body. However, after absorbing the moisture on skin, the inside and the outside of the fabric become equally wet. After taking in a certain amount of moisture, the fabric will start to stick to skin due to the capillary action between the wet surface and skin.
  • a variety of structures have been proposed to improve the moisture management capacity of fabric.
  • the general idea of these structures is to create the inside of the fabric such that it is more hydrophobic than the outside surface so that, during sweating, moisture can be transferred to the outside surface while the inside surface remains dry.
  • One solution is to pattern a certain area inside the fabric to be hydrophobic while leave the other regions hydrophilic ⁇ see, e.g., U.S. Pat. No. 7,008,887 and U.S. PG Pub. Nos. US2014/0230121, US2016/0090669, US2014/0106138, and US2014/0109282).
