This paper analyses the influence on its mechanic properties of PBO-AS fiber by high temperature, chemical solvent and sunlight, and compared with the mechanic properties of aramid fiber.

Research work and advances in relationship between light fastness of anthraquione dyes and its molecular structures in recent years were reviewed.

The basic principle of photochemistry of dye is briefly presented,and the factors affecting light fastness of the fabrics with reactive dyes are analyzed from this and some improving measures are accordingly taken in order to be helpful with manufacture.

In this paper passage treated the cotton fabric with surfactant,then dyeing with reactive lemon K-4G which in common dyeing process has low light fastness.

Through solar evaporation in 400 m~2 salt field in winter in Zabuye Salt Lake,the rule of composition evoltion of the brine is studied,and we explore and summarize the salt field operating situation and practical result of brine-preparation in winter.
