Problems solved by technology

[0002] At present, the biggest disadvantages of the tanning industry are: low leather yield, serious loose surface, poor fullness, serious environmental pollution, etc.
[0012] The biggest disadvantage of the traditional liming method is: "cooked inside and cooked outside"
"Raw on the inside and cooked on the outside" leather can be compared to an iron sheet covered with soft rubber on both sides. Although the elongation of the soft rubber is very large, due to the huge stress of the inner iron sheet, even if we exhaust our strength, we cannot pulling this complex apart

Abstract

A new adjuvant for leather production, and the use of this new adjuvant. The adjuvant contains alcohol compounds, inorganic, lactam compounds and sequestering agents of calcium, etc. The additive can be used in the leather production to generate special effects, capble of significantly improving the leather rate, thickness, fullness, flexibility of the leather, reducing the surface relaxation rate and significantly reducing the sewage discharges.

Description

technical field [0001] The invention relates to the field of novel auxiliary agents for tanning production. Background technique [0002] At present, the biggest disadvantages of the tanning industry are: low leather yield, serious loose surface, poor fullness, and serious environmental pollution due to the phenomenon of "raw inside and cooked outside". Although tanners have been working hard to solve these problems, the desired effect has not been achieved so far. After using the auxiliary agent of the present invention, these problems have been significantly improved, which is a breakthrough in the leather industry. The liming process is the process most closely related to these problems in the tanning industry. Here, we mainly describe the benefit, action mechanism and usage method of the additive of the present invention when it is used in the liming process. Of course, the additive of the present invention can also achieve similar effects when used in other processes...
