Abstract
Description
technical field
[0001] The invention is a chemical preparation for changing the waterproof performance of fiber-containing articles, so that the fiber-containing articles have a strong waterproof function. Background technique
[0002] Natural fiber-containing items such as wood products, leather, and paper products are prone to mildew, deformation, and brittleness due to moisture absorption, which seriously affects product quality.
[0003] At present, there have only been reports about leather waterproof and breathable materials in Ludwig's laboratory in Germany. Moreover, the laboratory's technology is not very mature, and the product can only be applied to leather. It can be applied on flexible materials, and the material has waterproof effect without changing the softness, air permeability, color, appearance, feel, etc., and the product that is convenient to use and simple in process has not been found. From a technical point of view, it is also very difficult to brea...
