What Does Sponge Remove Membrane Mean- Yancheng Oukai Sponge Products Co., Ltd.

As we all know, when producing sponge, even if the opening rate of sponge is more than 95%, there is still a lot of residual membrane between the meridians of sponge. When the light hits the surface of the sponge, it can be seen as dotted with points of reflection. This phenomenon affects the perception of sponges. Especially for coloring sponge, the existence of film, resulting in color material itself color distortion, such as: black is not black, red is not red.

In order to solve this problem, many sponge factories have made a lot of attempts on the production process and formula, and achieved certain results, but this fundamentally can not completely solve the problem. Some experiments have pros and cons. For example, when hair black cotton, improve the amount of black paste, sponge blackness increases, the cost also increases; In addition, the increase of the amount of black color paste to the foaming process control has brought adverse effects. After all this effort, the product is still “shining”. In view of this, we will develop a film removal and brightening agent to remove the film remaining in the meridians after the maturation of the sponge, which will be helpful to improve the quality of the sponge.
