Textile heating systems

An important aspect in designing textile heating systems is the type of yams to be used. Therefore it was decided to investigate the carbon loaded silicone yam (Fab-Roc ) which is made by mixing together silicone and carbon polymers, and then extmded in a patented process to produce FabRoc yam (see Figme 6.6). 

Chem. Analysis Sodium benzoate (90-92%), sodium nitrite (8-10%) Uses Corrosion inhibitor for antifreeze, closed cycle heating and cooling systems, domestic and industrial heating systems, summer coolants for internal combustion engines, hydraulic systems, emulsion paints, textile emulsions and adhesives corrosion-inhibiting impregnant for wrapping papers... 

In order to determine sensitivity of the textile heat fluxmeters, the conductive heat flux, which is constant at a steady state through aU of the elements of the unidirectional (z) thermodynamic system, was used (Eq. [19.9]). It was considered that the loss of the energy to the axes x and y is insignificant. 

The textile heat fluxmeter was soaked in distilled water in order to have a maximum retention rate. After soaking, it was immediately placed on a heating resistance. The whole system was fixed to the insulation material and placed on a scale. Simultaneously, the output voltage supplied by the THE and the weight of the measuring unit were recorded. 

The combination of heating systems with textiles is a niche sector, as the outcome could be very important. It is important to develop textile-based heating systems without compromising the flexibihty and the drapability of a textile. Therefore the investigation of how to create a comfortable wearable heating system is a very important area of research. 

Lamination. la lamination a film is prepared by caleaderiag or extmsioa (see Laminated materials, plastic). It is thea adhered to a textile at a laminator by either an adhesive or sufficient heat which partially melts the film to obtain a mechanical bond. There are a variety of adhesives available for lamination, including solvent systems, water-base latex systems, and various forms of hot melt adhesives (qv). 

P.R.170 is not always heat stable enough to allow application in polyolefins. In HDPE systems formulated at 1/3 SD, the pigment tolerates exposure to 220 to 240°C for one minute. Its tinctorial strength, on the other hand, is excellent. P.R.170 is also occasionally used in polypropylene and polyacrylonitrile spin dyeing in the latter medium, it satisfies the specifications of the clothing and home textiles industries. Besides, P.R.170 lends color to viscose rayon and viscose cellulose it is used for the mass coloration of semisynthetic fibers made of cellulose last but not least, it colors yarns, fibers, and films made of secondary acetate.
