Embodiment

[0015] The production process of automotive interior leather with ultra-low total carbon emission includes the following steps: A production process of automotive interior leather with ultra-low total carbon emission includes the following steps:

[0016] A. Hair preservation and depilation: After the cowhide is meat removed, 2wt% sodium sulfide, 1.2wt% lime, solid-liquid ratio 1:3 are used to pre-treat the cowhide so that the hair roots fall off and the hair is filtered out.

[0017] B. Softening: Enzyme softening treatment is performed on the depilated hides at a softening temperature of 30-32° C. and a time of 45 minutes. The enzyme preparation added in the enzyme softening treatment is pancreatin W, and the added amount is 0.3 wt%.

[0018] C. Tanning: subject the softened bare skin to a chrome tanning process to obtain leather.

[0019] D. Retanning / dying / fatting: Put the tanned leather into a drum for rinsing once, add 0.3wt% of low-VOC degreasing agent, 1H for degreasing, wash o...

Abstract

The invention relates to a production process of ultra-low total carbon emission automotive interior leather. The process steps include the steps of fleshing the cowhide, preserving and depilating hair, softening, tanning, retanning, dyeing, fatliquoring, drying, vibrating and softening, and finishing. The process of the invention controls the additives required in the step, so that the total carbon emission and atomization value of the automotive interior leather produced by the process is reduced, organic volatiles are controlled, and the process is healthy and environmentally 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 ...
