This instrument simulates heat and sweat production making it possible to assess the influence of clothing on the thermal comfort process for a given environment. Simultaneous heat and moisture transport through the clothing system, and variations in these properties over different parts of the body can be quantified.
  • the manikin consists of several features designed to work together to evaluate clothing comfort and/or heat stress. Housed in a climate-controlled chamber, the manikin surface is divided into 34 separate sections, each of which has its own sweating, heating, and temperature measuring system. With the exception of a small portion of the face, the whole manikin surface can continuously sweat.
  • preheated water is supplied from a reservoir located outside of the environmental chamber.
  • An internal sweat control system distributes moisture to 139 "sweat glands" distributed across the surface of the manikin. Water supplied to the simulated sweat glands is controlled by operator entry of the desired sweat rate. Each sweat gland is individually calibrated and the calibration values are used by the control software to maintain the sweat rate of each body section. Water exuding from each simulated sweat gland is absorbed by a custom made body suit. This specialty designed suit acts as the manikin's 'skin' during sweating tests. It is form-fitted to the manikin to eliminate air gaps and provides wicking action to evenly distribute moisture across the entire manikin surface.
  • Continuous temperature control for the 34 body segments is accomplished by a process control unit that uses analog signal inputs from separate Resistance Temperature Detectors (RTDs). These evenly distributed RTDs are used instead of point sensors because they provide temperature measurements in a manner such that all areas are equally weighted. Distributed over an entire section, each RTD is embedded just below the surface and provides an average temperature for each section. Software establishes any discrepancy between temperature set point and the input signal, and adjusts power to section heaters as needed. Temperature controls are adjustable, by the operator, for each heater control.

  • Conditional language such as, among others, “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain implementations could include, while other implementations do not include, certain features, elements, and/or operations. Thus, such conditional language generally is not intended to imply that features, elements, and/or operations are in any way required for one or more implementations or that one or more implementations necessarily include logic for deciding, with or without user input or prompting, whether these features, elements, and/or operations are included or are to be performed in any particular implementation.

Abstract

L'invention concerne une structure textile comprenant une ou plusieurs couches de fils de chaîne entrelacées avec une ou plusieurs couches de fils de trame, un revêtement de régulation thermique durable, et un liant qui lie chimiquement le revêtement de régulation thermique durable à la structure textile. Les fils de chaîne et/ou les fils de trame comprennent des fils polyester. Un procédé de fabrication d'une structure textile comprend le tissage d'une ou plusieurs couches de fils de chaîne avec une ou plusieurs couches de fils de trame pour former une structure textile tissée, le brossage de la structure textile au moins deux fois, l'application d'un liant sur la structure textile, et l'application d'un revêtement de régulation thermique durable sur la structure textile de sorte que le liant lie chimiquement le revêtement de régulation thermique durable à la structure textile. Le procédé peut également comprendre la thermofixation et le durcissement de la structure textile pour fixer de manière permanente le revêtement de régulation thermique durable sur la structure textile.
