Textile and industrial fibers respond to the environment according to their chemical composition and microstructure. Since fibers are typically semi-crystalline, they are generally more stable to both chemical attack and temperature then are wholly amorphous linear polymers. Polymer fibers are very good; indeed, they are the material of choice in some applications, yet they perform poorly in other environment. For example, polyolefins are virtually inert to inorganic, making polyolefin fibers useful as battery separator; however, polyolefins, like most other polymers, do not resist degradation in ultraviolet light. Consequently, polyolefin tent fabric is stabilized so that it can tolerate long exposures to sunlight. We will probe into the cause of poor ultraviolet stability in polymers and discuss ways to stabilize fibers.

擁有高昂興致去獲得資訊的消費者們較為喜好採納營養與產品的相關資訊，且較有可能採購外包提供營養成分的產品(引自某一篇論文)。獲取營養訊息的動機強化了營養成分標示的必要性與提高獲得資訊的可能性。

Language is like a life, we should learn it with flexible way, not just rely on book.
In this digital aged, everything goes digitize no matter in movie,music, games etc.Therefore, learning must digitize as well. We could use digital software to let learning English transform into our life in order to avoid learn English is not just read grammar books and trying to memory vocabulary in terms of boring things.
