The report is divided into four parts.

Part one: Introduction to Jiarong UNISOL Company. In this section, Mr. Dong provides an overview of Jiarong, including its basic profile, honors, technology, products, and application areas.

Part two: UNISOL Acid-Base Resistant Membrane. He describes the functions of the acid-base resistant membrane and its applications in the industry. The UNISOL acid-base resistant membrane can recover acids, bases, metals, and solvents under harsh conditions in industries such as chemicals and pharmaceuticals.

Part three: Applications of viscose fiber in membrane. This section explains the recovery processes for high-value alkali and hemi cellulose, analyzes data from processing stages of low, medium, and high concentrations, and highlights the current challenges, performance, and other application fields for alkali recovery using alkali-resistant film in the viscose industry.

Part four: Future development of membrane technology in viscose industry. This section discusses the future directions of some alkali-resistant membrane products, such as higher retention rates, higher flux, improved membrane modules and operating conditions, and capabilities for higher concentrations and pressures.
