Detailed Description
The present invention is illustrated below by way of examples, which should be understood as being illustrative of the present invention and not limiting thereof. The scope and core content of the invention are to be determined by the claims.
The scoring groove is an important device for wet processing of leathers and furs. The method is mainly used for the procedures of soaking, degreasing, liming, deliming, enzymatic softening, tanning and the like. The processing machine is divided into a wooden groove, a glass fiber reinforced plastic groove and a cement groove according to manufacturing materials, is semicircular, is provided with a wooden stirring paddle and is driven by a motor to rotate forwards and backwards, and is used for stirring operation liquid, stirring skin and accelerating the processing process. A steam pipe and a water pipe are additionally arranged, so that heating and water injection are facilitated. The movable cover is arranged on the upper surface of the cup body, so that liquid can be prevented from splashing or cooling; and a liquid outlet is arranged below the groove for discharging the operation waste liquid.
The biological enzyme treatment process is recognized as a green production process meeting the requirement of environmental protection, improves the wearability of textiles, and is also beneficial to the protection of ecological environmental protection because of no toxicity, no harm, small dosage, biodegradable wastewater and no pollution. Meanwhile, the biological enzyme is also applied to the field of treating indoor decoration pollution, and can eliminate the pollution of peculiar smell, formaldehyde and the like generated by indoor decoration through phagocytosis and decomposition.
The Tan sheep fur contains fibrin and non-fibrous protein which are present in fiber gaps and epidermis, although the content of the protein is low, if the protein is not removed, the Tan sheep fur is stiff and crisp. Therefore, the Tan sheep fur can be treated by using the biological enzyme.
