Resistive heating textiles

Looking at the research landscape on resistive heating textiles, some researchers concentrated on heat generation of polypyrrole-coated fabrics of different origins, such as poly(ethylene terephthalate) (Hakansson et al., 2004 Shang et al., 2010) or cotton (Bhat et al., 2006). Metallized or metal-based yarns, such as... 

Along with nylons, polyester fibers approach and exceed common natural fibers such as cotton and wool in heat stability, wash-and-wear properties, and wrinkle resistance. Blended textiles from polyester, cotton, and wool also can be made to be permanent-press and... 

The guarded hot plate is a standard instrument for measuring the relative thermal resistance of textiles as heat flows from a heated plate in contact with the textile and dissipates into still air at a lower ambient temperature via radiation, conduction, and convection. By design, it minimizes errors due to edge heat losses and validates the total quantity of heat flowing through the specimens. Convection and surface radiation can be controlled by use of a hood (2j+). Simpler devices such as the Reeves warmth tester and a chamois-covered copper cylinder also measure thermal... 

The SILIGEN types are additives, auxiliaries for producing special effects in textile finishing, or softening agents that resist heat.

However, none of these flame and heat resistant, technical textiles would be used without the necessary regulatory frameworks in place at national and international levels so that their technical performance may be assessed using accredited national and international test protocols some of these will be explored in greater depth for protective clothing in Chapters 9 and 10 and for transport in Chapter 11.

For most textile uses, a DS <1 is desirable. Cyanoethylation can impart a wide variety of properties to the cotton fabric, such as rot resistance, heat and acid resistance, and receptivity to acid and acetate dyes. Acrylonitrile and acrylonitrile polymers (qv) has also been radiation-pol5unerized onto cotton with a °Co source. Microscopical examination of ultrathin sections of the product shows that the location of the polymer is within the fiber (120). Examination of the ir spectrum of cotton-containing polymerized acrylonitrile indicates that grafliing occurs at the hydroxyl site of the cellulose (121). Another monomer grafted onto cellulose by irradiation is styrene polymers (qv). Chemical properties, mechanisms, and textile properties of these grafted poisoners of cellulose have been summarized... 

Another important future trend in heated textiles is the development of more efficient heating yams. FabRoc yam used in current research has variable resistance and conductivity. Future research should concentrate on reducing the variations and on how to produce finer even yam. 

The incorporation of e-textiles into military uniforms has helped achieve sophisticated functions such as physiological status monitoring, wearable power supplies and electric resistive heating. A soldier should be in good physical condition to optimally perform his or her mission. Health monitoring can help to improve the promptness in provision of medical facilities in the treatment of casualties. 

Urea-formaldehyde (UF) resins are mainly used as adhesives for wood. Laminated sheets (tables and counter tops) are a major application for melamine resins, which stay in the outer decorative surface. Molding compounds, their first big application, is still a major market, taking advantage of their extreme hardness and heat resistance. Coatings, textile finishing, paper additives, leather tanning and foundry binders, for which methanol- or butanol-etherified resins are usually employed, are important markets discussed in Ref 203. 

Their range of resistance makes conducting textiles suitable for resistive heating applications. Conductance can... 

Insulating products - Textiles for heat-resistant protective clothing are woven from spinning fiber, but most asbestos insulation products are in the form of paper, paperboard, millboard, and mat from paper-grade fiber. Asbestos provides flexibihty, dimensional stabihty, tear resistance, heat resistance, chemical resistance, moisture resistance, low thermal conductivity, and high electrical resistivity. Products include pipe wrap, thermal insulation in appliances, and electrical and heat insulation in electronics.
