Description

Technical Field

[0001] The utility model relates to the technical field of waterproof testing devices for waterproof leather, in particular to a waterproof testing device for waterproof leather. Background Art

[0002] Leather is a necessity in people's lives. Traditional leather does not have waterproof function, but leather treated with waterproof agent has waterproof performance, which is called waterproof leather. Waterproof leather is divided into hydrophobic and impermeable leather. Hydrophobic leather is made by impregnating leather with hydrophobic materials (organic silicone emulsion or silicone, etc.). When it meets water, the leather fiber reduces the surface tension, increases the contact angle with water, and makes water form water droplets on the leather surface and rolls down, which cannot wet and diffuse into the leather. It can be waterproof without affecting the water permeability of the leather. It is mostly used for the surface treatment of suede leather. Impermeable leather is made by adding waterproof agent into the leather when oiling the leather. When the leather meets water, a viscous water-in-oil emulsion will form in the gaps between the leather fibers to prevent water from continuing to penetrate and prevent water from penetrating from one side of the leather to the other.
