Systems and methods for preparing fish leather, which may comprise lionfish leather, are described. A method of making lionfish leather may comprise cutting, using one or more guidelines, at least a portion of a lionfish body, wherein the guidelines are configured to facilitate removal of skin from of the lionfish body; removing, using the one or more guidelines, the skin from the lionfish body, wherein the removed skin defines a cut skin pattern based on at least the guidelines; and subjecting the removed skin to at least a tanning process to provide a lionfish leather.

Provided is a composition for manufacturing leather comprising: hydroxide and borax (Na.sub.2B.sub.4O.sub.7•10H.sub.2O).

Provided is a method of manufacturing leather, comprising: preparing fabric including soaking, fleshing, liming, reliming, band knifing, deliming, and bating of natural leather; shaving the prepared fabric to a uniform thickness; neutralizing the shaved fabric to a pH of 5 to 7; flame retardant processing of performing a flame retardant treatment on the neutralized fabric with a composition for manufacturing leather; and drying the flame retardant treated fabric.

Use of probiotic technology to support tanners to reduce waste and increase the value of by-products reducing the need of synthetic chemicals, improving the quality of effluents and reducing the carbon footprint to the environment. Probiotics or beneficial microorganisms are used to obtain biochemicals through a controlled fermentation of natural ingredients. The result of the process is a consortium of metabolites including viable probiotic microorganisms with properties very similar to traditional leather auxiliaries extensively needed during leather production, eliminating or reducing the need for use of toxic chemicals and compositions.

The present invention relates to the field of suitcases, in particular to a multifunctional suitcase supporting both work and life. An automatic airbed or a waterproof sleeping bag is arranged inside a case body of the suitcase, so that the user can have a rest anytime and anywhere; a desk board and a folding stool are arranged in a case cover, so that the user can handle official business anytime and anywhere when going out. Meanwhile, a charging power supply and a mini speaker are also arranged in the case cover, so that the suitcase is more convenient and entertaining in outdoor activities. The suitcase has distinct structural gradation, diversified functions and easy access to articles therein, achieves the maximum space utilization of the suitcase and integrates work, life and entertainment functions, so that it can be applied to outing, camping, traveling, fishing, performance, military and other scenes.
