The present invention relates to a process for forming cellulose fibers or film from dissolved cellulose. The process comprises the steps of: dissolving cellulose in an aqueous coagulation sodium salt solution to provide a cellulose spin dope; extruding the cellulose spin dope into a coagulation bath liquid comprising an aqueous coagulation sodium salt solution to provide cellulose fibers or film; withdrawing a portion of the coagulation bath comprising coagulation sodium salt and sodium hydroxide (NaOH); cooling the withdrawn portion of the coagulation bath to precipitate solid coagulation sodium salt to recover sodium hydroxide (NaOH) substantially free from the coagulation salt; and using at least a portion of the recovered sodium hydroxide (NaOH) in dissolving the cellulose to provide the cellulose spin dope.

A balance trainer having a dome and a base formed integrally is provided. Also, a mold assembly for manufacturing the balance trainer that has a dome mold, a girdle, and a cover is provided. The girdle is sleeved on the dome mold and the cover is fixed on the girdle and thereby a cavity is formed in the mold assembly. Furthermore, a manufacturing process of the balance trainer is also provided. The process has the following steps: preparing ingredients of the dome and the base; feeding the ingredients of the dome into the dome mold; fixing a membrane on the dome mold via the girdle; feeding the ingredients of the base; sealing the ingredients via the cover; and then rotational molding. With the process and the mold, the rotational molding step can mold two materials at the same time, so the product can have two parts with different hardness.
