Novel fine mixed leather finished product sorting method

Abstract

The invention relates to the technical field of leather sorting, in particular to a novel fine mixed leather finished product sorting method. The method comprises the steps that fine mixed leather finished products are classified, the fine mixed leather finished products of the same kind are put into a fulling mill, and then the fulling mill is started; an air inlet valve on the fulling mill is opened, steam is injected into the fulling mill, the air inlet valve is closed until the temperature inside the fulling mill is 60 DEG C to 95 DEG C, and the fulling mill continues to rotate for 20 minutes to 30 minutes; a door of an outer sealed room is opened, the temperature inside the fulling mill is reduced to 60 DEG C to 85 DEG C, a feeding switch on the fulling mill is turned on, brightening agents are evenly sprayed into the fulling mill, the brightening agents are sprayed within one to two minutes, and after the brightening agents are sprayed, the fulling mill continues to rotate for 20 minutes to 30 minutes; the air inlet valve of the fulling mill is opened, natural air is led into the fulling mill, and the room temperature in the fulling mill and the room temperature in the outer sealed room are reduced to 20 DEG C to 40 DEG C; the fulling mill is closed, and leather is output. According to the novel fine mixed leather finished product sorting method, the labor intensity of an operation worker can be reduced, the working procedure is greatly reduced, the processing efficiency is improved, and the processing period is shortened.

Description

technical field [0001] The invention relates to the technical field of fur finishing, in particular to a novel finishing method for fine miscellaneous leather products. Background technique [0002] The finishing process of the finished product is a necessary process for the processing of miscellaneous skins, and it is also the last process before the fur is transformed into a finished product, and it is an important process that determines the quality of the finished product. The traditional finished product finishing process needs to consume a large amount of sawdust as the processing medium. The waste sawdust has high cost of treatment and low utilization rate of chemical materials. The sawdust is dusty to varying degrees, which affects the cleanliness of the wool quilt, and the sawdust sticks to the fur and is not easy to remove. Both reduce the quality of the fur, and at the same time, the traditional fine miscellaneous leather finishing process is cumbersome to operate...

The traditional finished product finishing process needs to consume a large amount of sawdust as the processing medium. The waste sawdust has high cost of treatment and low utilization rate of chemical materials. The sawdust is dusty to varying degrees, which affects the cleanliness of the wool quilt, and the sawdust sticks to the fur and is not easy to remove. Both reduce the quality of fur. At the same time, the traditional finishing process of fine miscellaneous leather products is cumbersome, with many steps, high labor intensity, high labor cost and long cycle.
