Embodiment

[0015] A production process of ultra-low total carbon emission for automotive interior leather, comprising the following steps: a production process for ultra-low total carbon emission of automotive interior leather, comprising the following steps:

[0016] A. Hair preservation and depilation: After the cowhide is fleshed out, 2wt% sodium sulfide and 1.2wt% lime are used to pretreat the cowhide with a solid-to-liquid ratio of 1:3, so that the hair root falls off and the hair is filtered out.

[0017] B. Softening: Enzyme softening treatment was carried out on the depilated rawhide. The softening temperature was 30-32° C. and the softening time was 45 minutes. The enzyme preparation added in the enzyme softening treatment was pancreatin W, and its addition amount was 0.3wt%.

[0018] C, tanning: carry out the chrome tanning process on the softened bare leather to obtain leather.

[0019] D. Retanning / dyeing / fatliquoring: Put the tanned leather into the drum for rinsing once, ad...

Abstract

The invention relates to a production process of automobile interior decorative leather with ultralow total carbon emission. The process comprises the steps of: cow leather fleshing, hair-saving, and unhairing, softening, tanning, retanning, dyeing, fat liquoring, drying, vibration staking, and finishing. The process of the invention controls the additive required in the steps so as to make the automobile interior decorative leather produced by the process has reduced total carbon emission and fogging value. Volatile organic compounds are under control, and the process is healthy and environment friendly.

Description

technical field [0001] The invention relates to a production process of ultra-low total carbon emission automotive interior leather, belonging to the technical field of industrial leather. Background technique [0002] At present, mid-to-high-end cars are equipped with genuine leather interior leather. The existing automobile interior leather generally has the following problems: high total carbon emission (total organic volatile compounds); high atomization value and heavy odor; the production process is not environmentally friendly, and the Lack of control of organic volatiles, the above problems need to be resolved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a production process for automotive interior leather with ultra-low total carbon emission. The product obtained by using the process has low total carbon emission and is environmentally friendly. [0004] In order to achieve this goal, technique of ...
