    Abstract: PCT No. PCT/JP89/00532 Sec. 371 Date Mar. 25, 1991 Sec. 102(e) Date Mar. 25, 1991 PCT Filed May 26, 1989 PCT Pub. No. WO90/14024 PCT Pub. Date Nov. 29, 1990.A dust-proof headgear which, although having a simple construction, exhibits an excellent dust-proof performance to thereby remarkably reduce a scattering of hair, dandruff and dust from the wearer's head, while exhibiting a high air-permeability to thus eliminate any feeling of sultryness or stuffyness even when worn for a long time. The dust-proof headgear is made of a material having, as a major component thereof, an electret non-woven fabric having a surface electrostatic charge density of 1x10-10 Coulomb/cm2 or greater and an air-permeability of between 10 cc/cm2.sec and 1000 cc/cm2.sec. The headgear of the invention is highly effective for use in various fields of industry in which environmental contamination by contaminants from the heads of workers or habitants is strictly forbidden, e.g., the foodstuff industry, electronic industry, precision machining industry, and medical industry.
