Nittobo Group strives to contribute to the realization of an enriched society,
serves as a valued corporate group in society, and commits to the creation of comfortable life.
Nittobo makes free use of single yarns, multiple twisted yarn, and other types of treated yarns to develop diverse cloth products based on the highest technology under rigorous quality control.
Woven glass cloth is rarely used as is (raw fabric). When used as a base material for composites, it undergoes heat treatment or surface treatment so that it has affinity for resin, or in order to give various characteristics to glass cloth according to the purpose of use, it is treated in various ways, including sealing. Only through these ways of treatment does glass cloth demonstrate the various characteristics of glass fiber to the fullest.
One of the greatest uses of glass cloth is to make the most of glass fiber's electric insulation, heat resistance, and dimensional stability for electric insulation. Glass cloth is combined with mica or varnish for components of heavy electric equipment (generators, power transformers, and electric motors) or light electric equipment (such as TV sets and microwave ovens). It is also used for laminated boards.

Glass cloth is used for FRP as mats and roving cloth are. It is employed for molded products that require high strength. It is also employed to make the surface smooth and improve impact resistance.
