Abstract

The invention discloses a process for quickly producing domestic goat skins. The process comprises the following steps of: washing sheared domestic goat skins with water, and putting the washed domestic goat skins in degreasing fluid for degreasing treatment; washing the degreased domestic goat skins with water, and tanning the washed domestic goat skins for 50-60 minutes in a tanning solution at 42-45 DEG C; washing the domestic goat skins after tanning, and then carrying out neutralizing treatment on the domestic goat skins for 60-90 minutes at 25-28 DEG C; rinsing the domestic goat skins after the neutralizing treatment, and drying the domestic goat skin after rinsing; carrying out spray dyeing on the dried domestic goat skins; and drying the domestic goat skins after spray dyeing. The process in which the production process steps of the domestic goat skins, a used tanning agent and a dyeing process are improved can be used for effectively treating the domestic goat skins, and the whole production cycle of the domestic goat skins is short, so that the production process of the domestic goat skins can be effectively improved.

Description

technical field [0001] The invention relates to the field of animal fur processing, in particular to a rapid production process of sheepskin. Background technique [0002] Tan sheepskin is one of my country's traditional export native products. It is well-known at home and abroad for its strong leather board, light weight and warmth, smooth and beautiful fur, and curved wave pattern. It is a unique animal husbandry resource in Ningxia. The existing Tan sheepskin tanning process mainly contains following several, namely chrome tanning method and aluminum tanning method. However, the traditional rapid production process of a kind of Tan sheepskin is cumbersome, including deashing-aldehyde tanning-washing-oxidation-dehydration-water washing-dehydration-reduction-water washing-dehydration-retanning-dehydration-fatliquor-drying-softening-refolding Tanning - standing - degreasing - washing - dyeing - color fixing - soaping - washing - drying - finishing and other 25 processes, th...
