PURPOSE:To enhance air permeability and to eliminate stuffiness and stickiness at the time of wearing while keeping the dust passing and collecting efficiency and low dust scattering properties of the max. level by forming a laminated structure from three layers consisting of at least one long fiber nonwoven fabric layer and long fiber knitted fabric layers holding the same therebetween. CONSTITUTION:Laminated cloth has a three-layer laminated structure wherein at least one long fiber nonwoven fabric layer is sandwiched between long fiber knitted fabric layers and the dust passing and collecting efficiency of particles having a particle size of 0.17mum or more thereof is 99.0% or more and the number of scattering particles having a particle size of 0.17mum or more thereof measured according to the shaking method of JIS B9923 is 10 particles/ft<3>/100cm<2> or less and the air permeability thereof measured according to the fragile method of JIS L1096 is 20-100cc/cm<2>/sec. As the material of the long fiber constituting the nonwoven fabric and the knitted fabric, polyamide, polyester, polyolefin or an acrylic resin are used. The dustproof clothing made of this laminated cloth has sufficient dustproof characteristics even in a clean room requiring a purifying degree of a high level and, since said clothing has air permeability of a definite value or more, excellent wearing comfortableness is obtained. |
