Embodiment Construction

[0029] The specific embodiments of the present invention will be described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0030] Unless otherwise expressly stated otherwise, throughout the specification and claims, the term "comprising" or its transformations such as "including" or "including" will be understood to include the stated elements or components, and not Other elements or other components are not excluded.

[0031] Such as Figure 1-3 As shown, a device for testing the anti-haze effect of fabrics includes: a support 1, an exhaust pipe, and a sample holder 2; the support 1 is provided with an exhaust pipe, and the exhaust pipe is provided with a sample holder 2 The sample holder 2 divides the exhaust pipe into two parts of different sizes, the larger part is the upstream box 3, and the smaller part is the downstream box 4; the upstream box 3 includes the fan 5 and the haze simu...

Abstract

The invention discloses a device for testing the anti haze effect of a fabric and a testing method thereof. A bracket is provided with an exhaust pipe; the exhaust pipe is provided with a sample clamp; the exhaust pipe is divided into a larger upstream box and a smaller downstream box by the sample clamp; the upstream box internally comprises a draught fan, a haze simulator and a dust particle detector; the haze simulator is used for producing dust particles and regulating temperature and humidity environments; an inlet of the upstream box is provided with the draught fan, the haze simulator is arranged in a wind outlet direction of the draught fan, and the dust particle detector is arranged at an outlet of the upstream box; the downstream box is internally provided with an environment simulator and a dust particle detector, and the environment simulator is used for adjusting the temperature and humidity environments and corresponds to the upstream box; a to-be-tested fabric is arranged on the sample clamp and is used for separating the upstream box and the downstream box. The device can adjust the wind speed, the dust particle size, the temperature and the humidity according to needs to test the to-be-tested fabric under different environments.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of fabric filtering effect test equipment, and particularly relates to a device for testing the anti-haze effect of fabrics and a testing method thereof. [0003] Background technique: [0004] In recent years, as the haze weather has become more and more serious, especially in winter, various anti-smog products have emerged, such as anti-haze masks, invisible masks, air purifiers, anti-haze cosmetics, and baby anti-haze covers. The use of these products in daily life is relatively limited. The current anti-smog products are achieved by reducing the porosity of the product. For mask products, it will undoubtedly reduce the air permeability and cause inconvenience to users. [0005] Anti-smog screens have developed rapidly in recent years, and products have emerged one after another. Anti-smog screens have two functions. One is to physically intercept large particles by the precision grid, and the other is to...
