Multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric, preparation method and application

The invention relates to a preparation method and an application of multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric. The multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric is formed by successively arranging and laminating a metal foil reflection layer, a phase change temperature limitation layer, an interval composite membrane heat-insulation layer and a flame-retardant comfortable layer, wherein the metal foil reflection layer has high reflectivity and an enhanced heat-dissipation function; the phase change temperature limitation layer has functions of high energy consumption absorption and evenly-distributed heat conduction; the interval composite membrane heat-insulation layer has the functions of reflection insulation and even distribution of heat; and the flame-retardant comfortable layer has the functions of low-contact heat conduction, heat insulation and comfort. When the front side of the multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric is under the action of open fire and strong heat flow environment, the back side of the multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric can be kept below 50DEG C which is near the safe temperature state of the human skin, and the integral structural form and the mechanical property are stable. The natural thickness of the composite fabric is 5-15mm, the compression thickness of the composite fabric is 3-8mm, and the square meter quality of the composite fabric is 400-1500g/m<2>. The composite fabric is fire-proof heat-insulation material which is totally sealed, stuck and sewn and can be used for individual protection and environment heat insulation in special high-temperature occasions, such as fire control, military, exploration, safe escape and industry and the like.

Fabric or garment with integrated flexible information infrastructure

A fabric, in the form of a woven or knitted fabric or garment, including a flexible information infrastructure integrated within the fabric for collecting, processing, transmitting and receiving information concerning-but not limited to-a wearer of the fabric. The fabric allows a new way to customize information processing devices to "fit" the wearer by selecting and plugging in (or removing) chips/sensors from the fabric thus creating a wearable, mobile information infrastructure that can operate in a stand-alone or networked mode. The fabric can be provided with sensors for monitoring physical aspects of the wearer, for example body vital signs, such as heart rate, EKG, pulse, respiration rate, temperature, voice, and allergic reaction, as well as penetration of the fabric. The fabric consists of a base fabric ("comfort component"), and an information infrastructure component which can consist of a penetration detection component, or an electrical conductive component, or both. The preferred penetration detection component is a sheathed optical fiber. The information infrastructure component can include, in addition to an electrically conductive textile yarn, a sensor or a connector for a sensor. A process is provided for making an electrical interconnection between intersecting electrically conductive yarns. Furthermore, a process is established for sheathing the plastic optical fiber and protecting it.

Method and apparatus for body impact protection

This invention relates to active protective garments which are inconspicuously worn by an individual and which activate upon certain conditions being met. Activation causes inflation of regions of the active protective garment to provide padding and impact cushioning for the wearer. The invention is an active protective garment such as pair of shorts or pants, a jacket, a vest, underwear, and the like. The garments comprise multiple layers of material that constrain pockets or regions that are inflatable by a source of compressed gas or foam. The garments also comprise sensors to detect ballistic parameters such as acceleration, distance, relative acceleration, and rotation. The sensor information is used to determine whether activation is required. Detection and activation are accomplished in a very short time period in order to offer maximal protection for the individual wearing the garment. The system comprises a computer or logic controller that monitors the sensor data in real time and coordinates the information from all sensors. The system calculates velocity, distance, and rotational velocity. A rule-based system is used to detect a complex fall in progress and discriminate said fall in progress from the events of every day life. The pockets or inflatable regions of the garment protect the individual against falls and other impacts that may cause bone fracture or organ damage.

Phase change material thermal capacitor clothing

An apparatus and method for metabolic cooling and insulation of a user in a cold environment. In its preferred embodiment the apparatus is a highly flexible composite material having a flexible matrix containing a phase change thermal storage material. The apparatus can be made to heat or cool the body or to act as a thermal buffer to protect the wearer from changing environmental conditions. The apparatus may also include an external thermal insulation layer and/or an internal thermal control layer to regulate the rate of heat exchange between the composite and the skin of the wearer. Other embodiments of the apparatus also provide 1) a path for evaporation or direct absorption of perspiration from the skin of the wearer for improved comfort and thermal control, 2) heat conductive pathways within the material for thermal equalization, 3) surface treatments for improved absorption or rejection of heat by the material, and 4) means for quickly regenerating the thermal storage capacity for reuse of the material. Applications of the composite materials are also described which take advantage of the composite's thermal characteristics. The examples described include a diver's wet suit, ski boot liners, thermal socks, gloves and a face mask for cold weather activities, and a metabolic heating or cooling blanket useful for treating hypothermia or fever patients in a medical setting and therapeutic heating or cooling orthopedic joint supports.
